Formula 267.30 free porn video
It had been a long day in the lab. Formula 267.30 had taken 6 hours to prepare, and it was finally done. Now I could inject it into the test subjects and set up the camera. Then in the morning I could see if there had been any changes.
I pulled some into a hypodermics and went to the testing lab. I looked at the chart and saw that cage 6 was available. I went over and looked over the notebook on the top. Ahhh, perfect. Subject F34 met all my needs. About 10 months old, she was the only female mouse in a cage with 6 males. While not aggressive with them, she always set herself apart, not joining in the nest for sleeping but staying apart. And other than if they absolutely forced it she would not engage in sex with any of them.
I smiled, made notes in the notebook, and gently pulled her out of the cage. A little swab of alcohol, I administered the injection and put her back in. It was like she was looking up through the top of the cage staring at me, as she went back to her own little corner.
“Oh, come on now 34, it's not so bad. Just a little prick.” I chuckled, and then watched for a few minutes. Then I saw one of the males perk up his head from their nest on the other side of the cage and sniff the air. He sniffed for about 15 seconds and crawled out of the bundle of other mice and work his way to her corner.
I then saw a second mouse give the same reaction. By this time, the first male (number M28) had approached F34. He went over to her and after sniffing her several times he crawled behind her and got in a position to mount. Now I remembered seeing this several times, but each time F34 would react the same way. Pulling away, showing teeth, backing up so her rear was against the glass of the cage. But not this time! Her head went down, and I saw M28 mount her. And for around 30 seconds he humped her like crazy then scurried off when he had finished.
He had just moved away when I saw M103 do the same thing! And once again F34 did nothing! I continued to watch as each and every male in the cage mounted her, 3 of them twice before all the males went back to their corner of the cage.
What in the hell had I found? I was supposed to be working on a d**g to help with the symptoms of menopause, that is why my subjects were females between 9 and 11 months old. This is roughly comparable to female humans between 35 and 45 years old. Ovulation stops, hormone levels change, hair follicles start to die, almost all the same symptoms, just time compressed.
But here was something I did not expect. The idea was that this could become a d**g to be used in treatment of symptoms, nothing more. Hot flashes, mood swings, even loss of sexual desire maybe, these were all things I had hoped this would cure. At the most maybe alleviate hair loss.
“Well F34," I said with a chuckle. “It seems that at least one symptom has been cured.” I injected the lone female mouse in each of the other cages, and each time it was the exact same result. A female that was past breeding age and therefore of little interest in sex was suddenly the center of a mousie gangbang.
The next day I pulled another sample and went to cage 9. I selected F67 and gave her the injection. Within 5 minutes the second of six males in her cage was mounting her and rutting like crazy. Apparently I had discovered something completely unexpected. As the night before, all females tested, all with the same result. They no longer fought off attempts to mate, and the males almost fought for them.
Over the next 2 days I tested it on all 12 of my female mice. And each time it was the exact same reaction. While none of the other females were as active in refusing male sexual activity as F34 was prior to the injection, within 2 minutes the males would start to approach her and mating would commence. Each time continuing until each of the male mice had mated with her. Sometimes 2 and even 3 times. One vigorous little fucker M423 mounted F62 5 times before he crawled back to his nest.
I collected up all my notes and headed home. By now I had made some graphs, which were interesting but told me nothing. Injections less than 4 hours apart had no effect. But each time so long as they were 4 hours apart would cause the same reaction in males and females alike.
On Monday I went to the “Zoo”, the basement level where all our mice were bred and kept unless they were needed. I selected 4 new female subjects, each one close to a year old or more. These were all well post-menopausal, and went back to my lab. F34, F62, F67, and F51 were removed and put into a euthanasia box and sent down to the vivisection lab as I introduced the new females to their new homes. 2 of them nested with the males, the other 2 nested alone. And there was no mating activities.
A few hours later after the lab was empty I gave them their injections. And it was the same results! Each time I injected them, within 2 minutes the males were surrounding them and pumping away with their little mousie rumps. And the females would do nothing, simply wait for them to finish.
Fascinating. Had I invented an orgy d**g?
Well, it was clear Formula 267.30 was causing some kind of reaction. I read over the vivisection results the next morning on the 4 subjects I sent down. Physiology was perfectly normal for mice into their middle age. Ovulation had apparently ended in 3 of the 4, none was gravid, no apparent negative bodily changes.
The next week after much testing I sent all the mice to vivisection and selected 12 females of 3-4 months of age, and 72 males. This time the females were entering their peak breeding age. And after each injection the same thing happened. Males would mount them furiously, this time for over 45 minutes for each female, one after another. But repeat injections had to come over 6 hours apart, and repeat performances were maybe 1 or 2 times.
Were these younger females causing the males to basically fuck themselves out? I held off the next morning in cage 12, and gave the injection to cage 11. Same reaction, for almost 45 minutes the males rutted on her. I then removed the males and swapped them with the males on Cage 12.
And as soon as I put them in cage 11 they immediately went to her. Another 45 minutes of non-stop mouse sex ensued, and the female almost looked comatose at the end. The next day I repeated the experiment, but after cage 12, 11, 10, 9, and 8 had their way with F96 in a span of 4 hours, I saw that she was not responding. I waited until all the males were satisfied. I had already learned that trying to remove a female during the frenzy risked getting bit by one of the males and possibly even one of the females!
I pulled her out and laid her in an examination tray. I looked closely, no apparent respiration. I touched, no apparent pulse I could find. I checked with a stethoscope, she was dead. Good god, did they actually fuck her to death?
The rest of the week I did a more careful repeat. But now carefully never more than 24 males for 1 female. And in all of these the females looked exhausted but recovered after 5 or 6 hours. The vivisection results from F96 came back. No obvious cause of death, not gravid, no abnormalities.
Once again another batch of mice the next week, others sent for vivisection. I repeated the experiment again, this time with males over 1 year old and 4 month old females. The males were only able to accomplish 1 or 2 matings each. By the end of the week 3 of the males had died, 2 of them “in the saddle”. All sent off for vivisection on Friday.
The latest batch had just been delivered and I was preparing for the first test of this round. This time I had 72 female mice, 6 in each cage. I was curious what the reaction of a female mouse would be to one of these with the injection. And then, I was fucking clumsy.
My phone rang as I was finished filling a syringe, and it distracted me. I ended up not putting the needle into the protective covering, but instead it went into my hand. And it apparently hit a nerve, because instead of my hand jerking away from the needle in a reflex motion, my hand did the opposite and jerked towards the needle. And I injected myself with Formula 267.30.
I felt sick, I felt scared. I quickly secured the lab, and called my supervisor and told him I was not feeling well and had to go home. I went downstairs to my car, and once getting in I laid there for an unknown amount of time. My body felt hot, and I was uncomfortable. And even my clothes did not seem to feel right. I realized I could not drive home in this condition, so headed to the train station.
Something felt funny in my walk, and even my shoes seemed as if they were too large for my feet. I used my bank card to buy a ticket and leaned against a sign as I waited for my train. Then I saw a man come up and stand next to me. I looked over at him, he was around 40, and I think Hispanic. He looked at me, and pulled me away from the sign and had me bend over leaning against it.
I felt my pants being pulled over my hips, and realized that they had been snug at my hips, something that should not have been. I felt fingers move between my legs, and it was... wrong. The hand should have been grazing my balls, and instead found a fleshy area that caused me to moan into my hand when rubbed. I then felt something hard and blunt pressed up there, and thought “Oh good god, this guy is going to fuck my ass and I can't stop him!”
And I moaned as he slid into me. But he did not slide into my ass, he slid into another opening which was positioned lower. I felt a sharp tearing pain as he entered, then pleasure! Oh good god sweet pleasure! I rested one arm on the sign and moaned into my other hand, as feelings like I had never felt before swept through my body. Then I felt a pulsing, then the man withdrew. I gasped as he left my body, and felt wetness on my thigh. Then another man entered me. I moaned and my hand moved away from my mouth, moving down to my chest. But I did not touch my chest, I touched breasts. I felt the part of my brain still working telling me that if I had breasts, then the men that were in me and not in my ass must be in my pussy.
My pussy! Good god, I was now female!
Number 2 finished, and was quickly replaced with number 3. And I realized I was feeling something I had never felt before. A tightness in my lower belly, like an anticipation. I looked over my shoulder and say the guy in me this time could not be more than 18, and I thought he was cute. And just then I lost all control, moaning as my legs wanted to give out and I realized I was having an orgasm!
Number 3 pulled out of me, and I knew for sure I was leaking fluids down my thigh. I saw number 1 move behind me, and gasped as he entered my body yet again. I recovered enough to look around the platform. There was another man standing a few feet away, just rubbing himself and watching. “Curious” I thought in the back of my mind, as I realize he looked effeminate and wore eye shadow. Watching, but not wanting to participate.
The females though, that was stranger still. They were ignoring what was happening. Not watching, not turning away. It was like I was not even there, and there were not multiple guys fucking me one after the other. Number 1 finished again, and I felt somebody get shoved and another penis plunged into me. I looked over my shoulder again, it was young number 3. And after 2 minutes he once again finished, and I can only assume number 2 took his second turn.
Finally I felt no more men. I pulled up my briefs and pants, and indeed my waist was smaller and my hips larger. I tightened my belt as much as I could, and only my wider hips prevented my slacks from sliding off. I felt like a wet sticky mess between my legs, and carefully walked into the train when it arrived and took a seat. I selected one at the back of the train, it was 3 seats wide. I took a seat, and saw that the 6 men inside the car were all looking at me. And the 8 women were all ignoring me.
Then one man 3 rows forward stood up and turned towards me. He opened his pants as he walked, and when he got to me he rotated my body and pushed me onto my back so my head was against the wall of the train, my legs over the seat hanging into the isle.
He opened my slacks, pulled them down to my knees, then moved my legs so they were pointing straight up. His hips moved against mine and I looked down. Indeed I was correct, my penis was gone. There were breasts on my chest, and I looked down my body between them and saw a mat of pubic hair, and I could only assume below that out of my sight was a vagina. A vagina that the man was pushing himself into.
I lost total count of how many men used me on that trip home. At least 10, maybe 15. I know several were more than once. One Asian guy who could have been 15 or 25 did me 4 times. Finally I heard my stop on the PA and said “Enough”, reaching up and pushing on the chest of the man inside of me. He pumped me a few more times, then grunted and came inside of me. I pulled my slacks back into place and stood up on feet that would barely support me.
I managed to get home without further incident, but did notice that females that passed me acted as if I was not there, and males across the street would stop and act like they were sniffing and looking for something. I got inside the house and went to the bathroom, stripping as I went. Then I took a deep breath and looked into the mirror.
Good god, I was really cute. My face had softened, looking more female. My hair was the same length, barely touching my shoulders. But it looked, nicer. My breasts really were breasts, maybe a C cup. I looked down my body in the mirror, afraid of what I would see, but also resigned to it.
Yes, my penis was gone, and obvious distended and swollen vulva peeked out between my thighs. And, they were a mess! Swollen and pulled slightly apart, thick white goop was slowly flowing out from between them, and some would drip down my thigh as some dripped down onto the floor.
I reached down, and touched myself. I moaned as my fingers made contact with what was now my clitoris, and shivered. Then down more, my lips were spread, and cum was leaking everywhere. I turned on the shower and spent 20 minutes cleaning myself down there. Then I crawled into bed and fell asleep.
My mind was full of dreams as I slept. I felt aroused, reliving all the guys that had fucked me on my trip home. Man after man, each one mounting me and I did nothing to stop them. Did nothing to discourage them until I realized I had to get off the train or risk having to switch trains and repeat this all over again.
And during these strings of dreams, I realized it felt good.
I woke up at around 6 in the morning, having slept for almost 15 hours. And I reached down, and felt my cock again. I went into the bathroom and took a piss, and everything functioned perfectly. I looked at myself in the mirror, and saw nothing different.
Had it been just a dream? Was the day before all a hallucination, caused by the injection I had accidentally given myself? I took another shower, having sweated heavily as I was dead to the world in slumber. Then I got out and after shaving I got dressed.
I went back into the bathroom to get my wallet from the day before out of my slacks. And I froze when I picked them up, and saw the inseam inside was stiff and white with something crusty. I set them on the counter and picked up my briefs from the day before. The center was the same, stiff and crusty.
That is when I realized it had not been a hallucination or a dream. I went to work and ran the experiment I had planned. On Monday and Tuesday I injected 1 female in each cage. And sure enough, all the other females ignored her. In fact, it was like they were avoiding her. They would not look at her, if she moved near them they moved away. In 1 cage I injected all 6 females, and they settled into 6 different areas of the cage. For some reason, if a female was injected with Formula 267.30, it was like they did not even exist to other females.
On Wednesday I sent them for vivisection, and pulled 72 male mice. In each cage I selected 1 male and injected him. And watched as over about 30 minutes they morphed into females, and the other 5 mice repeatedly mounted them. In cage 2 I injected 2 males, and the same thing. But each female settled on the opposite side of the cage as they were mounted over and over again.
I sent them all off for vivisection. And the results came back and I sat in my office and pondered them.
No pregnancies in any mouse given Formula 267.30. All males were normal males with no deviations outside of the expected norm. 6 of the reports even noted I had made a mistake on my end, reporting the males dissected as being female. So there was a post-mortem reversion back to male, even after death.
On Friday I locked up my lab and after putting a few vials in my pocket headed home. But first, I found myself stopping at a thrift shop. I selected 2 dresses that looked like they would fit, and a skirt that seemed like it would fall to my knees. Then a pair of sandals. I then went home.
I had a few drinks, then went into my bedroom. I removed all my clothes, and set my camera up to film what would happen. I laid on the bed, then gave myself an injection. And it was a repeat of the last time. I felt hot, sweaty, light-headed. I felt drunk, and could barely think for maybe 15 minutes. Then my head mostly cleared. I looked down, and sure enough I was female again.
I smiled as I reached down and explored myself. Breasts were indeed more sensitive on a girl than on a man. Moving down I found new places that caused reactions my old body never had. I moved all the way down, and checked all the parts. Clitoris, Vulva, Labia Majora and Labia Minora were all there. And oh so sensitive. I felt my Vagina, and could only get the first part of my finger inside.
I pressed and pushed, feeling an obstruction which was not really comfortable. Then I gasped as I felt something tear and my finger went back inside. Good god, it hit me as my finger slipped fully into myself, my hymen had returned! I experimented with my finger, and it felt amazing. I laid there and gave myself 3 orgasms, and each one felt better than the last!
Finally I took a shower, and threw on one of my white short sleeve shirts and the skirt. I had not gotten any panties, so just put my feet in the sandals and went outside. I had 2 chairs and a reclining lounger in front of the house, and took a seat on one of the chairs and watched the neighborhood, pondering what this all meant.
I saw Billy from next door on the sidewalk walking towards the house. He was a nice k**, about 16 and I sometimes let him mow my grass. I appreciated his doing it, and he appreciated the money. I waved at him, and he waved back. “Hi, are you a friend of Dr. Cassius?”
My mind raced. “Uhh, I'm his sister, Christine. Christopher is my brother.”
He turned and started to walk up my walk towards me. “Hi Christine, I'm Bill. I live next door.”
“Call me Chris please,” I said, and just then I noticed he had stopped walking and was just standing there staring at me. He walked more upright towards me. He lifted me out of the chair, and I felt his young but strong hands turning me around so I was facing my house, and pushing me over.
And my body did nothing to resist him as I bent forward and my hands grabbed the back of the lounger, and I felt the back of my skirt lifted up. Then I heard a zipper being lowered and Billy slid inside. He lasted a few minutes, then I again felt the throbbing inside, then wetness. He pulled out of me, gasping. Then 2 minutes later he was pushing into me yet again. This time he lasted over 5 minutes, and I came towards the end. Then more of that internal throbbing, and more wetness.
When he pulled out I moved over and collapsed onto the lounger, laying on my back and panting as I looked up at him. His face still looked slack, and like there was little thought in his head. Inside my head I was yelling that this is wrong, he was only 16 and I had to stop him. But I just lay there, and a few minutes later saw his cock stiffening yet again.
I could not control my thighs as they spread yet again. There was no control, it was like my body recognized a cock that was hard and ready for use, and wanted that use. Billy laid on top of me and my body welcomed him inside. This time I was feeling a body against me as it should be, his cock rutting inside of what was now my pussy, and I was moaning as I realized the rubbing against my clit was exactly what I needed. This time little Billy (who was not so little, he must have been 6 inches long) lasted for over 15 minutes and I came 2 more times before he once again spent himself inside of me.
I reached up and pushed him away, telling him we were done and he had to go home. He nodded, then pulled his pants back up. Then he simply turned and walked home. I went inside myself, and took another shower. I was feeling exhausted and crawled into bed.
The next day I gave myself another injection. I laid in bed and masturbated twice once the transformation was complete. One thing for sure, my orgasms were so much stronger as a female. I had just finished and heard a knock on the door. I threw on a robe and went to answer it.
“Oh, hi Chris. This is my friend Jack, we saw your lawn was a bit thick. We were wondering if your brother...”
That was as far as he got. I saw Billy and his friend standing there, slack jawed and looking at me. Jack gently pushed me inside, and Chris followed. Thankfully he also closed the door, because less than a minute later I was laying on my back in my living room, my robe on the ground and Jack both between my legs and inside of me. He lasted maybe 2 minutes, and right after he came he moved off and Billy took his place. Then 3 minutes later they swapped again.
I came again as Jack pushed into me for the second time, and he lasted over 5 minutes this time before spending in me. I felt him move off, and Billy had recovered enough to mount me again. I had yet another orgasm, my hands and legs wrapping around him, feeling so much better when a guy was on top of me rather than behind me. I came yet again as he did, feeling that throbbing inside my pussy.
When he pulled out I felt a large glob slip out from between my lips and ooze down over my asshole and then lower. By then Jack was once again moving between my thighs, and I spread them and my arms wide open to welcome him in.
Each repeat was now taking longer, as it was harder for them to cum each time. But this also allowed the boy not in me more time to recover himself. Each boy fucked me 5 times, and I was starting to get sore. I knew my pussy was a sloppy mess, and it felt like each time they pushed into my pussy, more of their cum was pushed out to flow over my ass and drip onto the carpet.
Finally I sat up as Billy finished number 5. “Enough, time for you boys to go home. You want to mow my brother's grass Billy? Come back tomorrow, he should be home by then. For now, get dressed and get out.”
I pulled on my robe, and the boys got dressed again. They headed towards the front door and I stopped them. “No, go out the back. I do not want anybody to see you two leave. Now go, goodbye.” I realized I needed another shower, I was a mess in more than one way. The mixture of my cum and theirs had not only run out of my pussy and over my ass, it had flowed up the crack of my ass when I was laying on my back. And now that I was upright, it was oozing down each of my thighs.
They had barely left when I heard another knock on the door. I opened it, and saw Bill there, Billy's dad. We sometimes had a few beers together, but I did not know him well.
“Oh, hello. You must be Chris' sister Billy told me about. I was looking for my son...”
I saw his nostrils flaring, and he moved closer. I sighed inside my mind, and moved back into the living room. I heard Bill following, and asked him to close the door. I dropped my robe on the floor and laid down, thighs already parting as I watched him drop his ugly Bermuda shorts. Then felt my pussy quiver as I realized that monster that must have been 9 inches long and thicker than I could ever imagine was about to be inside of me. I opened my thighs and arms again, welcoming him down and inside of me. And even though in the back of my mind I was gibbering, the part that was inside my body knew I could not resist this until it had its fill.
I felt his weight on top of me, my sensitive nipples being rubbed by the fabric of his shirt, and all thought left as I felt the fat head of his cock pressing between my labia.
I pulled some into a hypodermics and went to the testing lab. I looked at the chart and saw that cage 6 was available. I went over and looked over the notebook on the top. Ahhh, perfect. Subject F34 met all my needs. About 10 months old, she was the only female mouse in a cage with 6 males.

And other than if they absolutely forced it she would not engage in sex with any of them.
I smiled, made notes in the notebook, and gently pulled her out of the cage. A little swab of alcohol, I administered the injection and put her back in. It was like she was looking up through the top of the cage staring at me, as she went back to her own little corner.
“Oh, come on now 34, it's not so bad. Just a little prick.” I chuckled, and then watched for a few minutes. Then I saw one of the males perk up his head from their nest on the other side of the cage and sniff the air. He sniffed for about 15 seconds and crawled out of the bundle of other mice and work his way to her corner.

Something felt funny in my walk, and even my shoes seemed as if they were too large for my feet. I used my bank card to buy a ticket and leaned against a sign as I waited for my train. Then I saw a man come up and stand next to me. I looked over at him, he was around 40, and I think Hispanic. He looked at me, and pulled me away from the sign and had me bend over leaning against it.
I felt my pants being pulled over my hips, and realized that they had been snug at my hips, something that should not have been. I felt fingers move between my legs, and it was... wrong. The hand should have been grazing my balls, and instead found a fleshy area that caused me to moan into my hand when rubbed. I then felt something hard and blunt pressed up there, and thought “Oh good god, this guy is going to fuck my ass and I can't stop him!”
And I moaned as he slid into me. But he did not slide into my ass, he slid into another opening which was positioned lower. I felt a sharp tearing pain as he entered, then pleasure! Oh good god sweet pleasure! I rested one arm on the sign and moaned into my other hand, as feelings like I had never felt before swept through my body. Then I felt a pulsing, then the man withdrew. I gasped as he left my body, and felt wetness on my thigh. Then another man entered me. I moaned and my hand moved away from my mouth, moving down to my chest. But I did not touch my chest, I touched breasts. I felt the part of my brain still working telling me that if I had breasts, then the men that were in me and not in my ass must be in my pussy.
My pussy! Good god, I was now female!
Number 2 finished, and was quickly replaced with number 3. And I realized I was feeling something I had never felt before. A tightness in my lower belly, like an anticipation. I looked over my shoulder and say the guy in me this time could not be more than 18, and I thought he was cute. And just then I lost all control, moaning as my legs wanted to give out and I realized I was having an orgasm!
Number 3 pulled out of me, and I knew for sure I was leaking fluids down my thigh. I saw number 1 move behind me, and gasped as he entered my body yet again. I recovered enough to look around the platform. There was another man standing a few feet away, just rubbing himself and watching. “Curious” I thought in the back of my mind, as I realize he looked effeminate and wore eye shadow. Watching, but not wanting to participate.
The females though, that was stranger still. They were ignoring what was happening. Not watching, not turning away. It was like I was not even there, and there were not multiple guys fucking me one after the other. Number 1 finished again, and I felt somebody get shoved and another penis plunged into me. I looked over my shoulder again, it was young number 3. And after 2 minutes he once again finished, and I can only assume number 2 took his second turn.
Finally I felt no more men. I pulled up my briefs and pants, and indeed my waist was smaller and my hips larger. I tightened my belt as much as I could, and only my wider hips prevented my slacks from sliding off. I felt like a wet sticky mess between my legs, and carefully walked into the train when it arrived and took a seat. I selected one at the back of the train, it was 3 seats wide. I took a seat, and saw that the 6 men inside the car were all looking at me. And the 8 women were all ignoring me.
Then one man 3 rows forward stood up and turned towards me. He opened his pants as he walked, and when he got to me he rotated my body and pushed me onto my back so my head was against the wall of the train, my legs over the seat hanging into the isle.
He opened my slacks, pulled them down to my knees, then moved my legs so they were pointing straight up. His hips moved against mine and I looked down. Indeed I was correct, my penis was gone. There were breasts on my chest, and I looked down my body between them and saw a mat of pubic hair, and I could only assume below that out of my sight was a vagina. A vagina that the man was pushing himself into.
I lost total count of how many men used me on that trip home. At least 10, maybe 15. I know several were more than once. One Asian guy who could have been 15 or 25 did me 4 times. Finally I heard my stop on the PA and said “Enough”, reaching up and pushing on the chest of the man inside of me. He pumped me a few more times, then grunted and came inside of me. I pulled my slacks back into place and stood up on feet that would barely support me.
I managed to get home without further incident, but did notice that females that passed me acted as if I was not there, and males across the street would stop and act like they were sniffing and looking for something. I got inside the house and went to the bathroom, stripping as I went. Then I took a deep breath and looked into the mirror.
Good god, I was really cute. My face had softened, looking more female. My hair was the same length, barely touching my shoulders. But it looked, nicer. My breasts really were breasts, maybe a C cup. I looked down my body in the mirror, afraid of what I would see, but also resigned to it.
Yes, my penis was gone, and obvious distended and swollen vulva peeked out between my thighs. And, they were a mess! Swollen and pulled slightly apart, thick white goop was slowly flowing out from between them, and some would drip down my thigh as some dripped down onto the floor.
I reached down, and touched myself. I moaned as my fingers made contact with what was now my clitoris, and shivered. Then down more, my lips were spread, and cum was leaking everywhere. I turned on the shower and spent 20 minutes cleaning myself down there. Then I crawled into bed and fell asleep.
My mind was full of dreams as I slept. I felt aroused, reliving all the guys that had fucked me on my trip home. Man after man, each one mounting me and I did nothing to stop them. Did nothing to discourage them until I realized I had to get off the train or risk having to switch trains and repeat this all over again.
And during these strings of dreams, I realized it felt good.
I woke up at around 6 in the morning, having slept for almost 15 hours. And I reached down, and felt my cock again. I went into the bathroom and took a piss, and everything functioned perfectly. I looked at myself in the mirror, and saw nothing different.
Had it been just a dream? Was the day before all a hallucination, caused by the injection I had accidentally given myself? I took another shower, having sweated heavily as I was dead to the world in slumber. Then I got out and after shaving I got dressed.
I went back into the bathroom to get my wallet from the day before out of my slacks. And I froze when I picked them up, and saw the inseam inside was stiff and white with something crusty. I set them on the counter and picked up my briefs from the day before. The center was the same, stiff and crusty.
That is when I realized it had not been a hallucination or a dream. I went to work and ran the experiment I had planned. On Monday and Tuesday I injected 1 female in each cage. And sure enough, all the other females ignored her. In fact, it was like they were avoiding her. They would not look at her, if she moved near them they moved away. In 1 cage I injected all 6 females, and they settled into 6 different areas of the cage. For some reason, if a female was injected with Formula 267.30, it was like they did not even exist to other females.
On Wednesday I sent them for vivisection, and pulled 72 male mice. In each cage I selected 1 male and injected him. And watched as over about 30 minutes they morphed into females, and the other 5 mice repeatedly mounted them. In cage 2 I injected 2 males, and the same thing. But each female settled on the opposite side of the cage as they were mounted over and over again.
I sent them all off for vivisection. And the results came back and I sat in my office and pondered them.
No pregnancies in any mouse given Formula 267.30. All males were normal males with no deviations outside of the expected norm. 6 of the reports even noted I had made a mistake on my end, reporting the males dissected as being female. So there was a post-mortem reversion back to male, even after death.
On Friday I locked up my lab and after putting a few vials in my pocket headed home. But first, I found myself stopping at a thrift shop. I selected 2 dresses that looked like they would fit, and a skirt that seemed like it would fall to my knees. Then a pair of sandals. I then went home.
I had a few drinks, then went into my bedroom. I removed all my clothes, and set my camera up to film what would happen. I laid on the bed, then gave myself an injection. And it was a repeat of the last time. I felt hot, sweaty, light-headed. I felt drunk, and could barely think for maybe 15 minutes. Then my head mostly cleared. I looked down, and sure enough I was female again.
I smiled as I reached down and explored myself. Breasts were indeed more sensitive on a girl than on a man. Moving down I found new places that caused reactions my old body never had. I moved all the way down, and checked all the parts. Clitoris, Vulva, Labia Majora and Labia Minora were all there. And oh so sensitive. I felt my Vagina, and could only get the first part of my finger inside.
I pressed and pushed, feeling an obstruction which was not really comfortable. Then I gasped as I felt something tear and my finger went back inside. Good god, it hit me as my finger slipped fully into myself, my hymen had returned! I experimented with my finger, and it felt amazing. I laid there and gave myself 3 orgasms, and each one felt better than the last!
Finally I took a shower, and threw on one of my white short sleeve shirts and the skirt. I had not gotten any panties, so just put my feet in the sandals and went outside. I had 2 chairs and a reclining lounger in front of the house, and took a seat on one of the chairs and watched the neighborhood, pondering what this all meant.
I saw Billy from next door on the sidewalk walking towards the house. He was a nice k**, about 16 and I sometimes let him mow my grass. I appreciated his doing it, and he appreciated the money. I waved at him, and he waved back. “Hi, are you a friend of Dr. Cassius?”
My mind raced. “Uhh, I'm his sister, Christine. Christopher is my brother.”
He turned and started to walk up my walk towards me. “Hi Christine, I'm Bill. I live next door.”
“Call me Chris please,” I said, and just then I noticed he had stopped walking and was just standing there staring at me. He walked more upright towards me. He lifted me out of the chair, and I felt his young but strong hands turning me around so I was facing my house, and pushing me over.
And my body did nothing to resist him as I bent forward and my hands grabbed the back of the lounger, and I felt the back of my skirt lifted up. Then I heard a zipper being lowered and Billy slid inside. He lasted a few minutes, then I again felt the throbbing inside, then wetness. He pulled out of me, gasping. Then 2 minutes later he was pushing into me yet again. This time he lasted over 5 minutes, and I came towards the end. Then more of that internal throbbing, and more wetness.
When he pulled out I moved over and collapsed onto the lounger, laying on my back and panting as I looked up at him. His face still looked slack, and like there was little thought in his head. Inside my head I was yelling that this is wrong, he was only 16 and I had to stop him. But I just lay there, and a few minutes later saw his cock stiffening yet again.
I could not control my thighs as they spread yet again. There was no control, it was like my body recognized a cock that was hard and ready for use, and wanted that use. Billy laid on top of me and my body welcomed him inside. This time I was feeling a body against me as it should be, his cock rutting inside of what was now my pussy, and I was moaning as I realized the rubbing against my clit was exactly what I needed. This time little Billy (who was not so little, he must have been 6 inches long) lasted for over 15 minutes and I came 2 more times before he once again spent himself inside of me.
I reached up and pushed him away, telling him we were done and he had to go home. He nodded, then pulled his pants back up. Then he simply turned and walked home. I went inside myself, and took another shower. I was feeling exhausted and crawled into bed.
The next day I gave myself another injection. I laid in bed and masturbated twice once the transformation was complete. One thing for sure, my orgasms were so much stronger as a female. I had just finished and heard a knock on the door. I threw on a robe and went to answer it.
“Oh, hi Chris. This is my friend Jack, we saw your lawn was a bit thick. We were wondering if your brother...”
That was as far as he got. I saw Billy and his friend standing there, slack jawed and looking at me. Jack gently pushed me inside, and Chris followed. Thankfully he also closed the door, because less than a minute later I was laying on my back in my living room, my robe on the ground and Jack both between my legs and inside of me. He lasted maybe 2 minutes, and right after he came he moved off and Billy took his place. Then 3 minutes later they swapped again.
I came again as Jack pushed into me for the second time, and he lasted over 5 minutes this time before spending in me. I felt him move off, and Billy had recovered enough to mount me again. I had yet another orgasm, my hands and legs wrapping around him, feeling so much better when a guy was on top of me rather than behind me. I came yet again as he did, feeling that throbbing inside my pussy.
When he pulled out I felt a large glob slip out from between my lips and ooze down over my asshole and then lower. By then Jack was once again moving between my thighs, and I spread them and my arms wide open to welcome him in.
Each repeat was now taking longer, as it was harder for them to cum each time. But this also allowed the boy not in me more time to recover himself. Each boy fucked me 5 times, and I was starting to get sore. I knew my pussy was a sloppy mess, and it felt like each time they pushed into my pussy, more of their cum was pushed out to flow over my ass and drip onto the carpet.
Finally I sat up as Billy finished number 5. “Enough, time for you boys to go home. You want to mow my brother's grass Billy? Come back tomorrow, he should be home by then. For now, get dressed and get out.”
I pulled on my robe, and the boys got dressed again. They headed towards the front door and I stopped them. “No, go out the back. I do not want anybody to see you two leave. Now go, goodbye.” I realized I needed another shower, I was a mess in more than one way. The mixture of my cum and theirs had not only run out of my pussy and over my ass, it had flowed up the crack of my ass when I was laying on my back. And now that I was upright, it was oozing down each of my thighs.
They had barely left when I heard another knock on the door. I opened it, and saw Bill there, Billy's dad. We sometimes had a few beers together, but I did not know him well.
“Oh, hello. You must be Chris' sister Billy told me about. I was looking for my son...”
I saw his nostrils flaring, and he moved closer. I sighed inside my mind, and moved back into the living room. I heard Bill following, and asked him to close the door. I dropped my robe on the floor and laid down, thighs already parting as I watched him drop his ugly Bermuda shorts. Then felt my pussy quiver as I realized that monster that must have been 9 inches long and thicker than I could ever imagine was about to be inside of me. I opened my thighs and arms again, welcoming him down and inside of me. And even though in the back of my mind I was gibbering, the part that was inside my body knew I could not resist this until it had its fill.
I felt his weight on top of me, my sensitive nipples being rubbed by the fabric of his shirt, and all thought left as I felt the fat head of his cock pressing between my labia.
