Pent-Up

Vivian and I had been stealing glances at one another the entire evening, and on the occasions that we made full eye contact, the engorged organ hidden in my jeans grew increasingly out of sorts.

She was divorced, but I was, unfortunately, still tied down, and as shitty as my marriage may have been, I was reluctant to fuck it up. But... More than once, I'd found myself thinking an affair with her would be worth every bit of trouble that would come along with it.

If there were one thing about Viv that got me going the most, it would probably be those damn lips. It should be illegal for a woman to have pouty fucking lips like that. The first time I'd met her, all I could think about was how good those lips would look wrapped around the shaft of my cock. Fuck, just the thought of it had been enough to get me hard more times than I care to admit.

As delicious as those lips looked, they were just the icing on the cake when it came to the rest of Viv. Her figure could best be described as an exaggerated hourglass with massive breasts sitting atop a thin waist, which sat atop a thick set of hips and, fuck me is it absolutely perfect, round ass.

Needless to say, Vivian looked magnificent in all the right places, and knowing how much work she put into keeping her forty-three-year-old self in pristine condition, I have no doubts how a night with her would be. But I'd most likely never know.

In all the years we'd known one another, we'd played this game. A hint of subtle flirting here, some covert touching there, and a lot of lust-filled looks in between. By this point, we both knew what the other felt without ever having said one word about it and sadly, this fucked up cycle would continue in perpetuity because neither of us had the balls to act on our desires. So... Viv and I would spend the rest of our days in each other's presence, hinting at what could be, but never would be.

Deep down, I wished we could just fuck and get it over with already, but we both knew the ramifications our tryst would cause. Her marital status might no longer be an issue, but mine was; along with other

complications

, the main one at the moment being the raging erection I'd had most of the evening. It was beginning to get painful. I needed to either take care of it or do something to quell it the fuck down. So, excusing myself from the group, I went inside and to the upstairs bathroom. No one would bother me there in case I decided to relieve the pressure.

Once alone, I stood looking at myself in the mirror. Seeing the state I was in, it was a wonder no one had caught on to my condition. As worked up as I was, the release would probably feel amazing, but it would be an empty moment of gratification.

"Fuck it," I said to my reflection as I turned the faucet on.

Maybe a little cold water on my face would be better, but as I watched it swirl down the drain, I knew

that

wasn't going to resolve anything either. My problem would still be sitting downstairs awaiting my return. Frustrated, I turned off the sink and pulled the door open to find Viv standing there.

"I just thought I'd check on you, Steve," she said, biting her bottom lip. "Everything okay?"

Grabbing her hand, I jerked her into the bathroom with me.

"What do you think, Vivian?" I asked her with contempt as I locked the door. "My fucking head is about to explode."

One eyebrow arched up. "Which one?" she asked teasingly.

I could only stare at her before turning away with an exasperated sigh.

"We can't keep doing this," I told her more calmly. "It's only going to drive us crazy."

"Steve, don't you think I know that?" she asked with venom. "I want it just as bad as you do, but we both know why it can't happen."

Turning back to her, I placed my face within a couple of inches of hers. "Oh, I know alright, but I don't think I give a shit anymore."

It was Viv's turn to stare now, and her face was a mask of mixed emotions.

This was uncharted territory. Up to this point, everything had been kept at a safe distance, but now we were alone together and speaking of our need for one another openly.

"W-we can't, Steven," she mumbled eventually. "It's just not that easy."

"Bitch," I hissed vehemently before pinning her against the door. "If it wasn't so

easy

then why the fuck did you follow me up here?"

Viv had no answer for me and instead could only stutter which pissed me off even more. No longer interested in anything she had to say, I forced my mouth onto those amazing fucking lips of hers and shoved my tongue through them. The suddenness of my actions caught her off guard, but after a moment's hesitation, her tongue greedily wrapped itself around mine. The dam was finally broken, and as we made out, the two of us pawed at one another like inexperienced teenagers. This had been brewing for years, and now that the door was open, I wanted everything Viv had to offer.

Putting enough space between us, I slid my hands under her shirt and pushed it and her bra up over those huge tits. Calling them spectacular would have been an understatement. These were epic, and seeing the skin of Viv's giant areolas crinkle as her nipples hardened, I forgot all about her lips.

Taking both breasts in hand, I squeezed them roughly before placing my mouth on the nipple of the right one, biting it hard. Viv inhaled sharply through gritted teeth as she tried to push me away.

"Damnit, Steve. That fucking hurt."

"Sorry, Viv," I said, trying to hold on to her. "But as you can see, I'm more than a little frustrated."

She stared at me, her body tense, but finally she relaxed and allowed me to pull her into my arms.

"Look, I get it," she said with what looked like tears in her eyes. "I'm just as frustrated with this situation as you are, but you don't have to take it out on me."

She was right. We didn't ask for things to be the way they were.

"Okay. I'll be easier from now on."

As if to drive the point home, I took the same nipple back into my mouth, kissed it gently, and then began licking and sucking on it.

"Better?" I asked, grinning.

"Mmmm," Viv cooed. "Very much so. Now don't stop."

I wasn't planning on it, and as I continued to devour her flesh, Viv ran her fingers back and forth through my hair while moaning softly. They really were the biggest set of tits I'd ever had the pleasure of enjoying, but as much it pained me to say so, I was nowhere near satisfied with them alone.

"Over there," I commanded while jerking my head towards the bathroom counter. "Bend over it."

Without so much as a fuss, she did as I instructed, and I wasted no time taking my place behind her. Viv's reflection looked at me with hungry eyes, as I looked down at her denim-covered backside.

"This is ass of yours is too good for words, Vivian," I said through gritted teeth while grabbing a handful of it. "And you know it too, don't you?"

She nodded slowly. "I work hard to look like this."

"Oh, I know you do," I agreed. "I bet men would line up around the block for a chance with you, if you let them."

"I don't want

them

," Vivian said to me with determination as the eyes of her reflection stared into mine.

"Just me, huh?" I said eventually.

"Just you," she affirmed without hesitation.

Nodding silently, I returned my focus back to the beautiful ass before me.

"Damn it, Viv. It really should be a crime to have such a nice ass. I don't know whether to spank it, eat it, or fuck it. What do you think?"

Vivian just looked back at me.

"I don't care, Steve," she breathed out. "Do whatever you want. It's yours.

I'm

yours. Always have been."

"Well, so be it," I said, reaching around and undoing her fly. Then I curled my fingers into the waistband of her jeans and panties and forced them down over her hips, where they bunched up and stopped.

"Here, let me," Viv said as she stood up and kicked her shoes off. Then, with a little wiggle, she slid her clothes down her legs and stepped out of them before kicking them to the side as well. Finally, to finish things off, she pulled her top and bra off and threw them on the pile.

After years of wanting this woman beyond measure, she now stood before me completely naked and was mine for the taking. I wasted no time and pulled Viv into my arms, kissing her forcefully. The amount of heat coming off her flesh was insane, and I couldn't help but think of Icarus flying too close to the sun. Oh well, I was willing to get burnt to a crisp if it meant having this woman, and I was done waiting.

Breaking the kiss, I turned Vivian back to the counter, and picking up on what I wanted, she bent over it.

Looking down at her back, I ran my hands up and down the firm, toned muscles, then I moved on to the soft, smooth flesh of her ass. Unable to help myself, I pulled my hand back and slapped Vivian's right asscheek just enough to sting, but not injure. The sudden action caused my lover to jerk, and as I looked at her reflection, I noticed Viv was biting her bottom lip seductively. Grinning, I crouched down behind her. I was now getting a front row view of Viv's perfect peach with just a hint of bush peeking out below it. Reaching up, I began softly caressing her outer lips, and after a moment, I turned my attention to the slit in the middle where I inserted the tip of a finger and ran it up and down the cleft of Vivian's pussy. As I rubbed her inner lips, my lover moaned softly and pushed her ass farther toward me.

"My, oh my. Someone's impatient," I said, withdrawing my finger.

"No," Viv replied with annoyance. "I just want you to stop tormenting me already."

If she wanted it, I'd give it to her, so without a word, I put two fingers in my mouth, got them nice and wet, and then I slid them in up to my knuckles.

"Fuck," Viv moaned loudly. "You could have warned me."

I said nothing. Instead, I began savagely thrusting my fingers in and out of her wet snatch, and before long, Viv's annoyance became a distant memory. Over the next little while, I alternated between fingering her and eating her out, intent on not just making her cum, but pushing Viv over the edge so hard, she was left a quivering mess. Then, and only then, would the real business begin.

"Steve, fuck. I don't know how much more I can take," Vivian stammered. "I want your cock in me. Please, before I'm too messed up to stand."

"Not yet," I told her while continuing my assault on her now swollen pussy. "I want you to cum first. You gotta be getting close."

Seeing that there was no point arguing with me, Viv continued to brace herself on the counter as best she could, and eventually, I felt her body begin to spasm as she came. Then, while my lover's orgasm washed over her, I took the opportunity to shed my own clothes before taking my place behind her once more.

"Steve," she said through ragged breaths as she hung her head over the counter. "No more. I don't think I can take anything else. I'm wasted."

"No, Vivian," I said, snaking an arm under her waist to help support her. "We're too far into this to stop now."

Before she could reply, I took hold of my cock and buried in in her pussy up to the hilt. Vivian was a lot tighter than any woman I'd ever been with, and the sudden intrusion into her by something a good bit larger than a tongue or fingers caused her to squeal loudly.

"Quiet," I hissed while covering her mouth with my free hand. "Someone could hear. Now are you ready?"

Vivian stared at me in the mirror before finally giving me a hesitant nod. Bracing herself once more on the counter, I put both hands on her hips, pulled my cock almost out and then thrust it back in all the way. The impact of skin on skin echoed through the room, and Viv gave out an anguished moan.

"This has been a long time coming, Vivian," I told her as I continued making slow, hard strokes into her pussy. "We've been playing this game far too long, and it's time to put an end to it."

She couldn't answer with any coherence, but could only nod at me from the mirror as I fucked her.

"And there's no going back now," I continued. "Is there?"

"N-no," my lover was finally able to stutter. "N-no more talk, Steve. Just f-fuck me harder. Pleee-ease."

"Sure, Baby, whatever you want," I obliged.

Even though there was so much more I had to say, there would be time for that later, so instead I pored everything into fucking this woman whom I'd wanted for so long. They say when you want something so bad, it never lives up to your expectations once you get it, but this case was the exception. Fucking Vivian was everything I'd ever dreamed of, and every thrust into her tightness was like going to Heaven over and over, and the thing that got me going the most were the sounds of our love making: the wet squelch of her tight pussy as I stroked into it, the moans she exhaled with every plunge of my cock, and the sound of her massive tits slapping against her ribcage. Needless to say, it was all building to what I would have never expected to be the most amazing orgasm ever.

"I'm almost there, Vivian," I grunted out after a while. "I want you to cum with me."

She didn't respond. She couldn't respond. Viv was in her own world, but it didn't matter because no sooner had the words left my mouth than my lover's body tensed and then started to shudder. As she came, I felt Viv's pussy convulse around my member, pushing me over the edge.

"Fuck," I groaned as my orgasm hit me like an Amtrak.

My fingers dug into the flesh of Vivian's hips as I continued to pound into her, all the while shooting stream after stream of cum into her trembling pussy. The sensation of my cock pulsing and erupting inside of her pushed Vivian into a third climax and I had hell holding her in place so that I could empty the last bit of cum inside her as she bucked and writhed in ecstasy. When I finally felt the last vestiges of my orgasm slipping away, I let go of Viv and pulled my deflating cock out of her. Without it to stem the flow, I watched as an obscenely large amount of cum oozed out of Vivian's abused snatch while she did her best to come back down to reality. In the meantime, I found a towel and began trying to clean up our mess the best I could.

"Holy shit," Viv said eventually. "I've never been fucked like that in my whole life. Had I known..."

"Had you known what, Vivian?" I asked her, my frustration returning. "Let me guess. Had you known how good of a fuck I was, you'd have pushed for this sooner?"

"Hey, calm down, Steve," she said with frustration of her own. "It's not just about that, and you know it. What's between us is more than sex."

I sighed in defeat.

"I know, Viv, but the fact that we're in love with one another doesn't change things. I'm still married and..."

"And I'm your wife's little sister. I know. It's a whole fucked up mess. If only I hadn't been married when you and Jackie had met. Then things might have been different."

"Maybe so, but they're not," I said bitterly as I picked up her clothes. "Here, we'd better get dressed. People are going to start wondering."

"Yeah, I guess you're right," Vivian said reluctantly.

We finished dressing in silence, put the bathroom back in order, and then left separately. Thankfully, Viv had told the group she was going to her car to answer a phone call, and as far as I could tell, no one had questioned our mutual absences.

The rest of the evening was fairly uneventful, other than watching my wife drink way too much and act even more like the overbearing witch she was, but it kept her occupied enough so that she didn't notice her sister and me occasionally looking at or texting one another. We'd finally crossed the line, and a good bit of the pent-up sexual frustration between us was gone, but as I looked at the two sisters, it was never more apparent that I was in love with the wrong one. That in itself raised a whole new set of frustrations, and now that I'd had a taste of the grass on the other side of the fence, it was going to be hard not to throw my marriage away.
