A Stepmother's Sin - Chapter 5: I Try To Understand What Is Motivating My Stepson free porn video

Chapter Five: I realize I needed to understand Robert's motivation and desires better

It happens again the next morning.

I arose early, slipped out of bed without waking Robert. Silently, I went into the bathroom. I turned the water on, giving the hot water time to work its way through the pipes for my warm shower.

While waiting for the water to warm up, I stared into the mirror and assessed my thirty nine year old body. Objectively speaking, I was in excellent shape. My breasts were firm and perky, my waist was flat and small, and my hips and buttocks were in excellent proportion to the rest of me. Most people would have believed I was not yet thirty.

I reached down between my legs, squatting slightly and reached in to retrieve my diaphragm. As I pulled it free, a flood of semen mixed with my own juice spilled from my vagina in large globs that ran down my thighs. A few dollops of it spilled on to the floor between my ankles.

I tossed the diaphragm into the sink. I grabbed a tissue and wiped the globs of semen from the floor.

Up to that point, the events of the previous night seemed surreal and dreamlike. But here was irrefutable evidence dripping from me that yes, I had in fact allowed my stepson to enter me, and spill his seed deep inside me…..twice.

Rather repulsed by the gooey mess running down my thighs, I was intrigued by it, and somewhat amazed, at the sheer volume of his ejaculate. My young man had certainly pumped a full load inside me. It had been a long time since I had any man ejaculate inside me, but this seemed to be a much greater residual volume than I could ever remember before.

I reached down and scooped up two of the larger globs from my inner thigh on my finger tips, and I brought the spent semen up to my face to study it further. I held the semen under my nostrils, gently inhaling the scent; it was not at all unpleasant; on the contrary I enjoyed breathing in the aroma. I closed my eyes as I enjoyed my stepson’s most intimate fragrance.

I was reliving the experience through my sense of smell. I realized that very few stepmothers ever got to enjoy the scent of their stepson's semen. I guess that’s how it should be. Nonetheless, I was enjoying inhaling Robert’s scent for an extended moment.

The mirror was fogging up now, indicating that the hot water had arrived. I brought myself back to reality and stepped into the shower to wash away all the evidence of my crime; the physical evidence at least.

After washing and drying myself, I walking over to the sink and picked up the beige, concave rubber device that had been protecting my cervix from Robert's invading sperm. I washed my diaphragm, dried it, and placed it into its plastic container. I then placed the container and a tube of spermicidal jelly in my purse. I realized I needed to keep this handy and accessible while Robert was home for the summer.

I put on my make up, dressed and prepared to meet the day. I was early, it was not yet five forty five a.m.

I still had an hour before I needed to leave. So I sat at the kitchen table sipping my coffee, trying to make sense of the massive changes in my life and the events that caused them.

I could not make sense out of any of this. I alternated between gut wrenching guilt, a debilitating sense of anxiety and a level of excitement that I could not recall previously experiencing.

I heard Robert moving about. I looked up and saw him bounding down the stairs completely naked, his flaccid penis bobbing wildly in front of him. As he entered the kitchen he stopped and looked at me grinning.

“Well Willy, lookie who is here…..it’s Miss Cindy,” he said, referring to me by my first name in a show of familiarity that indicated a level of comfort with this situation that I had difficulty comprehending.

“Willy?” I questioned.

“Miss Cindy - or should I say Mom? - let me introduce you to my good friend Willy," as he motioned to his penis. “I actually think you two have already met,” he said coyly. “In fact, if I remember correctly, you two have become very close friends.”

My god, he was a confident and cocky bastard. He was his father’s son, no question about it. Almost on cue, Robert’s penis seemed to pulse upward as though it was a 'one eyed man' trying to look up at me during our ‘introduction’. As I watched, his penis pulsed and throbbed several times, each time growing slightly longer, thicker and stiffer.

When it was sticking straight out from his tight abdomen, about half erect, I said, “That is amazing. Is this going to happen every time you enter a room where I am?” 

 He was only partially erect yet it was already about six inches long and was hanging just south of horizontal. Even though he was only partially firm, my young lover had the start of a very impressive boner already.

“I think so mom,” Robert said confidently, pausing before continuing, I was more than a little distracted as I watched ‘Willy’ continued pulse as he grew erect before my very eyes.

“Willy is a lot like Pavlov’s dog. He starts salivating when he hears the bell ring. He is merely reacting to being in the presence of the most beautiful and sensual woman on the planet.”

“Oh my God,” was all I could utter. “You are a most amazing young man. Never have I seen anything like this. I have never known anyone like you. Your length, girth and ability to respond are like nothing I have ever seen before.”

I was genuinely astonished.

“I have never seen a man grow erect without physical contact. I didn't even know this was possible.”

Had I not witnessed it myself, I still would not believe it happened.

As strange as it might sound, I couldn't help but feel some level of pride in my stepson’s physical and sexual prowess. He was a remarkable specimen. At six foot, two inches, with broad shoulders and muscular chest, he had the physique that looked like he just stepped out of Greek mythology. And his penis was the most impressive male tool that I had ever seen.

In so many ways, Robert reminded me of his father, only Robert seemed to be more attracted to me and was far more smitten with me than Jim ever was. Robert's attentions were highly flattering. But perhaps the most flattering thing was the way his penis did, in fact, respond to my mere presence. Robert’s response to me was incredibly appealing to me.

I could feel myself grow wet as I watched my boy grow erect as a tribute to me! I knew I was falling in love with this young man in a deeply emotional way. I was on a very dangerous path.

I had never felt so desirable in my life. If this had been the neighbor’s nineteen year old son, I would have no conflict at all; I would simply think that every thirty nine year old woman needed a nineteen year old lover. However this wasn’t my neighbor's college aged son; this was my stepson. And I was deeply conflicted right now. I did not know what to do.

“What are you going to do with that thing now that you have him fully awake?”

“It is an offering to my goddess. It is an offering to you.”

He stood there proudly displaying himself.

“Robert, I have to go to work. I cannot stay home and play.”

“Mommy, you can’t leave me like this all day. Look at me. Look at our friend Willy. We need your immediate assistance, Miss Cindy. Please? We are both crazy about you.”

He looked at me with the biggest puppy dog eyes while sporting the biggest boner I had ever seen; the irony was obvious.

I sat staring for several seconds, contemplating my options here. How did my world change so dramatically and so quickly? How did I become responsible for Robert’s frequent boners and responsible for initiating his orgasms?

Finally, shaking my head in disbelief, I said simply, “Come here.”

He walked towards me, his erection swung side-to-side with each step. My god, he was a magnificent specimen, he was an Adonis, he was my Adonis. He stood in front of me, and I reached up and took his rigid tool in my fist, stroking him slightly.

“Before I assist you and ‘Willy’, tell me, have you been a good boy?”

“Oh, I have been a very good boy,” he answered in a feigned little boy voice.

“Yeah, what have you done that is so good? What have you done to earn my assistance that you claim to need so badly?”

He thought for a moment before answering, continuing to rock his hips to encourage my strokes. “Well, I gave my mommy an orgasm last night.”

“I am not sure that qualifies as ‘being good’, young man. It seems to me that you have been pretty bad lately. In fact, if I remember correctly, you tried to fuck me bareback, even though you knew I was not on the pill.”

“But I didn’t, did I? I was a good boy, wasn’t I?”

“Well, you sure did try to fuck me bareback; you tried real hard, didn’t you?”

He got serious for a second. “Mom, you have no idea how badly I wanted to enter you last night, here in the kitchen. You have no idea how hard that was.”

“Son, I am well aware how ‘hard it was’, it was pressing into my vagina as I convinced you to stop. In fact, you ‘poked your head in a bit’ before you stopped. You were well past the front door when I got you to slow down and reconsider. I just hope you didn’t leak any of your little 'spermies' into me. You could be one minor plumbing leak from having a brother and son in once fell swoop.”

I continued to stroke him, and he continued to rock his hips as we talked.

“Mom, I know. I know I was already in a bit. It was all I could do to keep from plunging into you. It was really tough for me to pull back and wait.”

“I know, Robert. But you must never do that.”

He nodded in agreement as he humped my fist.

I decided that Robert needed to articulate that fact. “Repeat after me ‘I will not try to fuck my mommy unprotected any more.’ Go ahead, let me hear you say it.”

Robert made an expression that indicated he thought this little exercise was silly. He seemed like he did not want to say those words. So I stopped stroking his erection for a second and waited.

Robert quickly relented and said, “I will not try to fuck my stepmom unprotected any more until she is on the pill, which she needs to take care of right away. I promise.”

“One more time…”

“I will not try to fuck my step mommy bareback any more until she is on the pill. I will not pump my stepmom’s pussy full of my potent cum….”

He just could not keep from ‘cracking wise’ with me, even on this subject.

The fact that he was obviously very proud of his virility and the 'potency of his semen' was not lost on me. I wondered if, on some level, he did actually want to impregnate me? I put that thought out of my mind momentarily, but made a mental note to get on the pill quickly as a preventative measure.

“Good boy.”

I brought his erection to my lips, kissed it several times, placed the tip of my tongue into the opening slit. A loud guttural moan escaped him as I tongued his slit which told me he liked the tip of my tongue probing his urethra. He liked it a lot.

I took him into my mouth and slowly brought him to a slow torrid orgasm. As he came, I continued to suck and swallow; I certainly did not need my stepson’s cum spots on my business suit. Beside, I had recently learned that I found the smell and taste of Robert’s semen enjoyable. Who ever would have guessed?

When I thought he was done ejaculating, I took him out of my mouth, but another small translucent white drop appeared on the tip of his glans, I leaned forward and licked it off, realizing that I truly enjoyed the taste of Robert’s semen. Swallowing him seemed the most natural thing in the world now.

“Thank you. I needed that.”

“I know you did, baby. Go get dressed, I have to go.”

I stood up and hugged him. I noticed that he made no attempt to kiss me. It was clear that having just cum in my mouth, he did not want a taste of his own medicine, so to speak. Men are strange animals indeed; they love to have us women ingest their semen, but they want no part of tasting their sperm themselves.

Moments later, as I walked out the door, I heard him say, “Mom, I love you so much.”

And I knew he really did. 

At the office...

I arrived at work, still aware of the very faint taste of Robert’s semen and uncertain what I should do, or what I could do with this emotionally and morally complicated mess in which I found myself. But my first step was to go to the ladies room to brush my teeth. As irrational as it might sound to you, I was fearful that the scent of Robert's semen might be detectable on my breath.

I was paranoid that someone would somehow instinctively uncover the truth and discover the horrific act I was committing. Part of me kept questioning whether or not I was truly the monster that society would label me if they only knew. Mothers do not sleep with their stepsons, ever. But I had done just that.

I did not fully understand how this all happened, although I felt very culpable. My childhood Catholic upbringing taught me plenty about guilt, as well as some about forgiveness. I was feeling an enormous burden of guilt, and I feared I could never be forgiven.

I could revisit the events leading up to this moment, but to what end? Yes, I should not have invaded his privacy the night I saw him first masturbating. And yes, I should never agreed to our mutual masturbation session, that was totally over the line. And I should never have allowed him to touch and taste me. Each mistake led to another. But I do not know how I could have prevented last night; Robert was intent on having me, with or without my diaphragm in place. I knew then as I know now, it was far better to agree to insert my diaphragm and allow my stepson to enter me, than to try to resist and risk having him take me without protection.

On the other hand, I was not a victim here. I did respond physically to Robert’s attentions, and I did respond emotionally as well. I responded in a profound and shattering manner. I should not have; I wish I had not, but I had.

So what now? The important thing was doing what was best for Robert. He seems to have no problem with the current arrangement. He seems to have no pangs of guilt. I needed to think more; I needed to have a serious discussion with Robert. I also needed to understand better what was really going inside Robert’s head. Then I thought, I do not even understand what is going on inside my head! I was totally confused.

Later that morning I called my ObGyn and got a prescription for birth control pills. I did not know what the future would hold, but it was clear that neither Robert nor I could be trusted to put these events in the past where they belong, and I knew that I did not have the physical or emotional strength to stop him from taking me whenever he chose. And I was not sure I could turn away from the pleasure my stepson gave me either.

When I picked up the prescription over lunch, the pharmacist reminded me to use another form of birth control for at least seven days after starting to take the pill. Note to self, keep diaphragm in place whenever there was any risk or potential.

Back in my office, I shut my door and sat silently, trying to sort things out. I needed to assess how this happened and what to do about it. Just how culpable was I? Did I do something that caused Robert to come on to me, or was I merely thrown into a difficult and unexpected situation to which I responded poorly? What exactly did I do to encourage Robert to feel so comfortable pushing the boundaries with me? When did I cross the line from being his mother to being a sexual target for him? How did this happen?

Wait, I realized, I was asking all the wrong questions. While understanding my level of culpability might lessen, or increase the level of guilt I was already feeling, it was not going to help me determine what I should be doing next? Unintentionally, I had crossed a line that should never have been crossed, actually several lines. On the other hand, Robert was of legal age, and he was a fully developed and mature man; at least physically he was.

And although I knew what Robert and I did was wrong by any measure, he did not think it was wrong; he thought it was one of the most beautiful encounters two people could experience. Was I really in a position to argue against his assessment? Could he be right? Could it be that these would be the most precious and cherished memories he ever experiences as he passed through life?

I had to accept the fact that not only wasn’t I going to change Robert’s view of this, I was not going to be able to dissuade him from trying, in a most tenacious manner, to maintain the physical nature of our relationship.

And did I really want to dissuade him?

Objectively speaking, on one level, I felt the proper thing was to stop this craziness; however, I knew I would be unable to resist his determined full pressure assault on my will power and my loins. On a very deep level, I knew I desired this to continue as much as Robert did; perhaps more. After all, as a college student, Robert had numerous other alternative sexual outlets available. I did not.

Although I verbally had discouraged Robert's advances, I did not resist enough, if at all. In fact, my physical reactions did nothing but encourage my stepson to continue. While I was saying the word ‘no’, I was allowing Robert to remove my panties, and I was squatting and opening my thighs to give Robert better access to my most intimate parts.

I did enjoy his touch. I loved the feeling of having him inside me, filling me and stretching me open. I loved the feeling last night of laying with Robert inside me in a post-coital cuddle as I slowly descended from a powerful orgasm. Wrong as it was, I enjoyed it, a lot.

I would like to think that if I really wanted to do so, I could behave better going forward, but I was fairly certain I would not be able to resist his pressure and advances. He simply knew how to push my buttons too well. And I felt certain his pressure would continue after the success he had had so far.

Okay, if I could not institute a “dead stop” on the physical and sexual aspects of our relationship, what were the rules? First, I needed to make sure that I was protected from pregnancy. I would use my diaphragm religiously in addition to getting on the pill starting today. Robert and I needed to have a candid discussion and agree what was in and what was out of bounds.

It was now five o'clock, time to go home and face my son.

Going home to face Robert

As I got up to leave, it dawned on me, I needed to always have my diaphragm in place when I came home. Robert needed not know I had it in place, but I could not risk being taken, either by force or by seduction, without having time to get my protection in place.

I went into the ladies room with my purse. I entered the stall, opened my purse, removed the beige diaphragm and filled it with spermicidal jelly. Sitting on the toilet, I open my thighs, and inserted my diaphragm, covering the opening of my cervix. At least now I had a barrier to protect me from becoming pregnant by my stepson.

I convinced myself that I was doing this as a strictly precautionary measure, not intending to resume the intimacies with my stepson. I convinced myself that I did not know what I would encounter at home, and had to be prepared in case Robert go too insistent.

I shook my head in disbelief that I had inserted my diaphragm in case my nineteen year old stepson insisted upon taking me tonight. Amazing. And being honest with myself, I knew if he 'insisted', I would cooperate.

I arrived home that night to find Robert had prepared a meal for the two of us, and had already chosen a bottle of wine for us to share over dinner. He was attempting to create a romantic mood for his ‘date’ tonight.

“Can we talk?” I asked as I sat down at the dinner table with a plate of blackened tilapia in front of me.

“Sure, what do you want to talk about?” Robert said with a sly grin.

I took a sip of merlot as I gathered my thoughts.

“About all that has happened between you and I the past two nights. I realize I may not be able to convince you that this is wrong, or that it should not have happened, or that we need to stop and place this in the distant past….”

Robert interrupted, “That’s good. My work here is done!” he said as he pumped a celebratory fist in the air for effect.

“Robert, please, don’t joke now. This is not a good situation for you. You should be chasing college girls, developing relationships with girls your own age, and ultimately finding one you will marry and raise a family with.”

“Mom, I intend to do all those things. But I want you too. I need you. All I ever wanted was to have a woman like you. Now, not only do I have a woman like you, I have you. And I am never, ever letting you go. You are mine now. There is nothing anyone can do about it; not you, not anybody. A part of you will always belong to me.”

There was a real passion and conviction in Robert's words as he spoke. I thought I actually heard his voice crack slightly revealing the level of emotion he too was feeling right now.

Once again, my head was swirling.

There was no question, Robert was feeling deep, passionate and real love; not simple teenage lust. To him, this was a committed relationship; a life long commitment of sorts. It was wrong, it was twisted; but it was real, genuine, and to him, beautiful.

I could not help being flattered that any man could be so taken, so in love and so committed to me. It was certainly more complicated and emotionally charged since this man was also my stepson; but it was flattering nonetheless. No man had ever been this taken with me, or smitten with me. If I am honest with myself, I must admit that at that moment, I did not want to give this up either.

It was also clear that Robert did not think he was doing anything wrong for him, or for me. He did not see any way that passionately loving me would harm me. And it was clear that he was a very tenacious and determined young man, and he was not going to be dissuaded from this course upon which he had set us both.

After several moments of uncomfortable silence, I responded to what Robert had said, “Robert, you need to understand that I really believe we made a mistake, what we did was wrong, and that we should stop this insanity now…”

“I will not let you make this into something ugly or wrong,” he interrupted.

“I think I understand that - or at least, I accept that is how you feel. I disagree. But I accept that I am not going to change your mind. But you do need to understand that I really think we should stop.”

I paused to let that sink in.

“But regardless of whether or not I can convince you to stop, we need to establish some boundaries and guidelines,” I said while watching closely for Robert's reaction

Robert initially looked puzzled, and then he smiled, relieved at this sign that I was considering some scenario where we would continue.

“What would those boundaries be?” he inquired. His demeanor was much more positive now that he understood that I was not going to insist we end this torrid love affair at all costs. He seemed to be actually beaming at the thought that I was agreeing to continue our intimacies.

“Well, first, you need to have other interests, pursue other girls your own age; if not while you are here, certainly when you return to college.”

“Okay, that seems fair. Are you going to date other men while I am staying here this summer?”

This brought a huge smile to my face.

“No, I think I can give up my very active dating life for the next three months while you are here. Robert, I have not been ‘on a date’ in nearly six months. I have not been ‘with a man’ in the sexual sense in nearly a year prior to me ‘being with you’ last night. My dating, and my sex life have been very boring, and very inactive. Robert, my sex life prior to you was... well... non-existent.”

I chuckled as I answered.

“That’s good, because, to be honest, I would not like to have other guys taking you out, and ‘doing you’ while I am here.”

“Doing me?” I laughed.

“You know what I mean. I know that we are not going to be a monogamous couple for the rest of our lives, but for the time I am here, I want you to belong to me, and only me.”

“You are cute, and that is very sweet. Okay, while you are here, I will be your woman. You will be my man. It will be an interesting summer,” I said, shaking my head at the absurdity of the situation.

Then it hit me, I just agreed to 'go steady' with my stepson.

"Robert, no one can know about this, ever; especially not your father," I said emphatically.

Robert's expression turned immediately to exasperation. "Of course, mom. Do you think I am stupid?"

He was obviously a bit insulted that I felt the need to point out the obvious.

"Robert, I know you know this; but you can't ever slip up. If you are sitting around the dorm, drinking with your buddies, telling tales about wild sexual adventures, you can't say 'I got one that will top you all...I banged my stepmom this summer'."

"Mom, I know that."

"And Robert, normally I would never advise you to keep anything from your wife, when you get married someday; but this is one intimacy that needs to remain between you and me. Your wife can never know what you and I shared, okay?"

"Mom, I promise you, I will never tell a soul. I will never disrespect you in any way. I realize people would not understand what we are doing. But mom, this is not about sex; it is about love. I love you. That's why I want to be with you."

I could feel tears form in my eyes as I knew he was right; this was about love and intimacy, not sex.

"God, I love you Robert."

"I love you too, mom."

"Robert, one last thing. We need to keep the intimacy inside the house. When we are out in public, we need to act like a stepmother and her son, not like lovers. There can not be any 'public shows of affection'; not even holding hands."

Robert nodded indicated that he understood.

"Mom, do you think maybe we could take a short trip this summer and go somewhere that no one knows us? Somewhere we could actually go on a real date? Maybe go dancing? And hold hands?"

"Robert, you are so sweet. Perhaps we can. I think I would like that too. But let's not get ahead of ourselves."

I smiled, deeply pleased at the thought of Robert and I taking a trip this summer and being able to act like a true couple in public. Perhaps Atlantic City might be an option? Or upstate New York? I would have to work on this later.

Robert stood. The bulge in his pants was noticeable. I finished my glass of merlot. Robert stepped around the table, took my hand and pulled me to a standing position. He guided me to the living room couch. It was clear that this discussion was over for the time being.

We kissed deeply, each of our tongues exploring the other’s mouth. Robert began unbuttoning my blouse, removing it and then my bra; leaving my smallish, but perky tits exposed to the air-conditioned air. My nipples stood up proudly on display. I started unbuttoning Robert’s shirt and removing it. I was still in awe of his taut abdomen, as well as his well defined chest, shoulders and arms.

"Robert, I just love your chest and arms. God, you are a gorgeous young man," I said while caressing his chest, and gently teasing his nipples. "Baby, if I had known someone like you when I was in college, I likely would have gotten knocked up before my eighteenth birthday. I could never say 'no' to you."

It was an honest admission to my nineteen year old stepson that I would not refuse him, not tonight, not tomorrow, not ever. By telling Robert that I could never say 'no' to him, I was actually making a commitment to my stepson. I was committing to allowing him access to his stepmother's pussy for the rest of his life.

I don't know if this commitment was lost on him, but at that moment I knew I would never deny my stepson access to me for the rest of his life. I belonged to him!

 I leaned forward and took one of his nipples in my mouth sucking it, much the way he had sucked my nipples last night. I kissed his chest, and massaged his erection through his pants.

While I was caressing and kissing him, a thought re-entered my mind. I wanted to test whether or not the thought of impregnating me aroused him, or if it scared him. Was the risk of getting his stepmother pregnant part of the excitement and allure of the torrid affair that he had imposed on the two of us?

I did not know what I would do with the knowledge, but on a very core level, I wanted to know.

As Robert unzipped my skirt, I raised my bottom off the couch allowing him to remove it. I fumbled with his belt and zipper of his slacks. It was a bit embarrassing, my stepson was far more nimble and adroit at undressing me than I was at undressing him. I guess he had far more practice in college than I had recently.

For a moment, I wondered how many girls had Robert been with? I felt a silly pang of jealousy come over me as I realized that my nineteen year old stepson likely had more sexual partners than I had in my entire life. I forced the thought and the jealousy from my mind.

Robert finally assisted me in releasing his belt, and the top clasp of his pants. He stood, and removed his pants, boxers and socks quickly. His penis was partially erect already.

Robert kneeled in from of my, separated my thighs, and he kissed my pussy through the wet material of my panties. I lifted my bottom up to allow him to remove my panties.

He sat back down next to me.

We were now both naked, necking and groping each other on the couch. To me, there was something sexy about being naked outside of the bedroom. I can’t quite explain it, but it added to my excitement.

As we necked on the couch, I lowered my hand into his lap and found his penis. Robert’s erection was large, rigid and standing straight up on its own. God, he was sexy, no question about it.

I softly ran my fingers around the ridge that separated the glans from the meaty shaft of his cock, barely touching him. The head of his erection swelled and pulsed in response to my very soft touch.

Robert arched his hips, attempting to increase contact as he moaned in frustration. I continued to tease him, barely touching the smooth, very sensitive skin of his glans and the area right beneath the head.

"Shit, mom... I can't take that... you are driving me crazy."

"I know. That's why I do it."

Robert patience with my teasing was wearing thin. He stood up, pulling me standing as well. As he did the previous night, in order to kiss me more comfortably without bending over so far, Robert placed my arms around his neck, and simply hoisted up my tiny frame, grabbing my both my legs and pulling me so I was straddling his well conditioned torso; my arms wrapped tightly around his neck as we kissed.

I liked the way he was able to lift my light frame at his will. It made me feel petite and vulnerable; somewhat powerless in the presence of this strong powerful man who was both my lover and my stepson.

I felt the head of his erection bouncing against my legs and buttocks as we necked like teenagers. I guess that should not be too surprising since one of us was a teenager. Then I felt his cockhead start to search more urgently for my opening, or any opening!

Just as had happened the previous night, once the head of his penis found the wetness of opening Robert arched up for gain entrance to my wet and dilated vulva.

Since he did not know that I had already inserted my diaphragm, I decided to tease, and test, him a bit. I was curious to see how he would react to my teasing.

With the head just at the opening, actually inside me less than an inch, I broke off our kiss and said, “whoa baby, you can’t go inside me quite yet.”

He looked at me puzzled, as if to say, ‘Why not?’

“Baby, I need to get my diaphragm in place.”

But rather than pull away, I held myself steady, my arms propping me up on his shoulders. Then I lowered myself ever so slightly, allowing his cock to edge inside me another half inch or so. I had just the head inside me inner folds. I looked into his eyes with all the love and lust I had, and I contracted my vagina to give the large bulbous head of his cock a loving squeeze.

The moan that escaped his lips and the sudden pulse of his entire penis let me know he felt my contraction, and he liked it. He liked it a lot.

I told him, “Baby, you feel so good. You stretch me wider than anyone ever has. But you can’t go inside quite yet.”

I adjusted my weight on his shoulders slightly causing me to slide down on his rigid pole just a bit. “Oh, baby, you need to lift me off your tool. I will get my go diaphragm in place. I will do it quickly.”

I contracted my vagina once again; and his penis throbbed again in response.

“But, Robert, you can’t fuck me bareback. You just can’t. No matter how good it feels.”

And I squeezed his cock's head with my vagina one more time.

I was getting an enormous amount of pleasure from teasing my boy like this. I was watching the facial expressions. He was completely lost in his lust for me at that moment.

Since the very first night, when he caught me spying on him in my voyeuristic moment of weakness, I have felt like he had all the power, all the control. Robert had been pulling all the strings. But now, for these last few moments, I felt I had regained some control.

And most importantly, I knew something he did not know. I knew that my diaphragm was in place; I had started taking the pill; a protective barrier was there to keep him from impregnating me. But Robert thought the risk of pregnancy at that moment was very, very real.

What would he do, I wondered?

I adjusted my weight again, pushing on his shoulders and pushing my legs down against his strong hands that we holding me in place with his cockhead just inside my vulva. I lifted up, barely allowing his penis to exit my vagina, but, after hovering over him for only a second, immediately lowered myself a bit so that one to two inches of his massive pole returned into me.

With just the head of his penis inside me I kissed him deeply, sucking his tongue inside my mouth as I contracted my vagina again.

I repeated my request, “Baby, please lift me off of you so I can put in my diaphragm. Please don’t fuck me bareback. I am in the fertile part of my cycle. If you cum in me, I could get pregnant. And neither of us want to have your baby growing in my belly.”

I contracted my cunt again as I teased him; trying to determine if he would lift me off the rigid tool that was just starting to pierce my vagina, or would he take me right there standing in the living room and spill his seed inside me? Would Robert try to impregnate me?

As I contracted my vagina again, hugging the head of Robert's cock one last time I hissed into his ear, “But you do feel good, baby. You do feel very good.”

I leaned forward and kissed him again deeply, this time, probing my tongue into his mouth. I was hot, I was as aroused as I could ever remember. And my passion was clearly present as I sucked his tongue into my mouth in this deep soul searching kiss, the head of his hard cock throbbing anxiously inside me a couple of inches. This was very sexy and I was very aroused. I knew I was going to cum tonight, it was building already.

Robert broke off the kiss and leaned me backwards, separating the distance between our shoulders while holding my hips to keep his penis just inside me. My arms were stretch out, my fingers locked together behind his neck, holding myself in place.

It appeared he had made a decision as to whether to set me free to allow me to install my diaphragm or not. As he leaned me backwards, my body formed an angle with his torso. He was holding me back almost horizontal now, the head of his penis had now slid inside me several of inches, but was still only halfway inside me. I looked between my legs and could see that at least four inches of his thick shaft remained outside my vagina..

In this position, the rigid head was pressing up firmly into the front wall of my opening, pressing on my very sensitive g-spot. Yes, I was going to have an orgasm tonight, and I would not hold out long. Robert’s cock was so rigid that it felt like his dick could support my entire 105 pound frame if he released me from his grip.

He moved his hands from under my legs to my hips where he pulled me, suddenly and violently, towards him, fully impaling me on his erection.

The suddenness of his large penis piercing my vagina was unexpected and, surprisingly painful, and extremely stimulating. I was not ready to accommodate his full length and girth.

The sudden shock of pain and pleasure as he impaled me evoked a loud screech from deep in my core. It was a sound I had never before heard, and certainly never before made. (I do not even know how to imitate the guttural sounds I made at that moment.) Of course, the sudden penetration was like nothing I had ever experienced or felt before either. 

But the shot of pain subsided quickly and rapidly became waves of pleasure as my vagina was forced open to accommodate my stepson’s erection.

This massive penetration initiated my orgasm. My hands were now clasped, fingers interlocked behind Robert’s neck as I held on for dear life, Roberts’s hands on my hips pulling me into him violently to meet the rapid thrust of his hip as he pulled in and out of me. His thrusts slapped up against my ass and thighs, bouncing me up and his strong hands were catching me and positioning me for his next thrust.

Being a relatively petite (and short) woman, I had never been able to make love standing up. My partner was always too tall. And no one had been able to lift and move me with such ease to fuck me in the manner and position that my muscular stepson was at this moment.

The rigidity of his penis, and the ‘angle of attack’ forced the head of his cock to strike the front wall of my vagina with such force that it initiated a very powerful orgasm that had me responding uncontrollably to the rapid and violent pounding my stretched little pussy was being subjected to.

I was being bounced up with each thrust only to be driven back down to meet the next one. I was crying out, I was afraid I would pass out.
