I Fucked My Wife’s Sister While She Was Out of Town

“Shhh,” she put her finger over my lips. “It’ll be worth it. I’ll do things with you my sister has never done before.”

One night, a couple of days after my sister-in-law, Monica, moved in with us after her boyfriend kicked her out for some apparent reason, the two of us were sitting on the couch watching TV. My wife was out of town for a couple of days, on a business trip, and we were both bored.

Every time I glanced at her, I found her just staring at me, pure lust in her eyes. A couple of times I think I even caught her rubbing her jean-clad pussy as she stared at me, which made my cock throb and twitch as it started to grow hard.

I don’t know what came over me, but a little over an hour into the movie, I stood up and looked down at her little form, and before I could think that this was a bad idea, I leaned over and started kissing her passionately.

“I was wondering when you were going to finally do this,” Monica suddenly said, breaking my kiss and I saw her beautiful green eyes looking up at me.

“Uh… I-I’m sorry,” I stuttered as she sat up, all the while smiling at me.

“There’s no need for an apology,” Monica said and grabbed my hand.

“I’ll go take a walk outside. I’m sorry about what happened. Please forgive me,” I said with shame in my eyes and tried to leave but she caught my hand and pulled me back.

“Please don’t leave,” she said, then looked down and saw the bulge in my pants. “I think we both want something.”

“I want you to know I don’t do this… I mean… I’m not one of those guys…”

“Shhh,” she put her finger over my lips. “It’ll be worth it. I’ll do things with you my sister has never done before.”

It was the absolute last thing in the world I would have ever expected to happen.

“Oh, you’re killing me, Monica,” I whispered. “If your sister finds out about this… or your parents…”

“No one will know, relax,” she said while holding my hand against her face.

She took my thumb and put it against her lips, licking it slowly and then sucking on it seductively while looking into my eyes.

“Please?” she asked, fixing me with the most intense gaze. She bit her lower lip, and I shivered from the sexy sight.

I was done the moment her top slid up and over her breasts. She wasn’t wearing a bra over her little mounds. Her nipples stood out, pointing toward me; long and large in contrast to the breasts they adorned. The small circles surrounding them had only the slightest blush of pink to contrast with her fair skin.

Monica reached up, slid her hand behind my neck, stood on her toes, and kissed me hard. My inhibitions shattered, and my tongue slipped over hers, while my hands explored the soft skin of her bare back. She grabbed my shirt and yanked it out of my pants. A moment later, she pulled away from our kiss with a gasp. I lifted my arms, allowing her to take off my shirt, and toss it away.

She went straight for the fastenings of my pants, looking up at me with a level of needy desire I hadn’t seen in ages. Her eyes remained locked with mine, her lips slightly parted as her fingers continued their work. When she finally pulled my dick out and curled her fingers around it, I couldn’t resist and leaned in for another hungry kiss.

Her hand pumped up and down my shaft as we kissed, and we both gasped when our lips parted. She sat down on the couch, holding onto my cock for as long as possible. As soon as she sat down, she lifted her right foot.

I slipped off her shoe, and let it clatter to the ground. Monica unbuttoned her jeans and began to wrestle them down even as I removed her other shoe. While she wriggled and pushed at her jeans, I quickly shoved mine down and began to stomp my way out of them. A few seconds later, we were both naked, and she turned to recline against the arm of the couch.

A loud whimper escaped her when I bent over her and sucked her pebble-hard nipple between my lips. One of her hands moved to caress the back of my head, while she wormed the other between our bodies. I groaned around her nipple when her fingers tickled the head of my cock.

“Yes. Oh yes,” she cried while arching her back to press her breast tight against my lips.

I suckled and tongued her nipple, making her squirm beneath me. After a few seconds, I switched to its twin, drawing another whimper from her.

Suddenly, she pushed me and put her left foot on my chest, keeping me at distance, toward the opposite end of the couch. Her eyes lit up and a thrilled, open-mouth smile decorated her face. She pulled her knees up and out in anticipation, letting me see her pussy in all its glory.

Her folds were the perfect pink of youth, with a glimmer of wetness shining from the center. A prominent hood wasn’t enough to conceal her large clit, which peeked out from beneath it. She teased her saliva-slick nipples while parting her lips with the other hand, revealing a shimmering pucker that I could almost feel wrapping around my cock, from the mere sight of it.

“Mmm hmm,” she moaned as I leaned forward between her legs, catching a whiff of the perfume of her arousal just before parting her folds with a stiffened tongue.

Monica moaned loud and long when I probed deep to gather up her nectar, lapping for every drop I could reach, aided by her hips lifting to grind her pussy against my lips.

She gasped once, twice, and then a third time before emitting a loud, “Oh!” and a shudder rippled through her lithe body, and her next several cries sounded even more arousing.

I growled and flicked my tongue even faster. Up and down. Side to side. Diagonally. A hand pushed on the back of my head, her fingers stiff and trembling. I paused long enough to give her button a hard lap, lifting the hood and exposing more of her clit before renewing the assault.

“Oh! Oh my god! Yes!” she erupted into joyous laughter.

A feminine grunt escaped her when I pulled her hood back with my thumb, exposing the once-guarded little pleasure nub to my tongue and she yelped when I attacked her naked clit with rapid laps, and then a brief suck.

Her breathing quickened. When I glanced up, I could see the flush in her cheeks. I wanted more, I wanted her to come. I sucked her hood and pulled it in, my upper lip pressing against her clitoral shaft and she cried out, arching her back from the sensation and then again when I sucked hard and rolled her clit with my tongue as rapidly as I could manage.

“Yes. Yes. Right there. Like that. Don’t stop. Don’t stop,” she cried out in a voice that grew louder and higher in pitch with every exclamation.

What followed were exclamations of almost words, a sudden tightening of her muscles, and then a scream of release, before her thighs clamped down around my head with ferocious strength.

Monica thrashed and bucked while I continued to lick her throbbing button. Her muffled cries rang out between gasps for breath. Her nails dug into my scalp and back. For the first time in years, I felt truly alive with the beautiful young woman climaxing on my tongue.

Her upper body lurched upward and she screamed, burying my face in her pussy for a second. Her hips fell as rapidly as they had risen and her feet lashed out, pushing me away, and I finally relented.

She rolled onto her side and curled into a quivering ball, jerking and yelping with each shockwave of her slowly decreasing orgasm, and drew in ragged breaths between them. I caressed her leg, my eyes roaming from her flushed face to her pussy winking at me from the continuing contractions of her intimate muscles.

“That was… Wow,” she said in a nervous voice. “Nobody has ever licked my pussy like that before.”

I leaned over her and pressed my lips to hers. Our kiss was long and deep.

“I taste pretty good, don’t I?” she asked, licking some of her juices off my chin.

“Like heaven.”

“I need you inside me,” Monica said, biting her bottom lip, then licking the upper.

I took my cock in hand, right behind the head, and rubbed it between the parting of her lips. She was soaked to the point of dripping from my tongue, and the very first swipe left me quite slippery. An explosive gasp escaped my mouth as I slipped inside her. She was absolutely tight, her walls molding around my cock like a second skin.

She squealed as my cock stretched her out, slowly opening her up a little more with each thrust.

“Yes. Yes. Yes,” Monica cried out in time with my thrusts.

She grasped the couch cushions in a white-knuckled grip and yelled when my balls slapped against her on the very next thrust. I moved my right hand from her thigh to her clit, and began to roll it beneath its protective sheath.

“Oh! Oh! Oh my! Yes! Yes! Ah!” she screamed as the flush in her face deepened and spread down to her neck.

Loud claps sounded from our colliding flesh, mingling with my exertion grunts and her pleasure yelps. Her little breasts quivered. Her head lashed back and forth. Her eyes grew wide and rolled up in her head.

“Come for me,” I said while rubbing her clit faster and harder.

Her body undulated as if cracked like a whip and she screamed loud as her orgasm took hold of her. She quickly put her arms around my neck, pulling me closer, while her feet thumped into the small of my back. I kissed her as I gave her short, quick, deep thrusts into her climaxing pussy.

She moaned and gasped into my mouth, clawing savagely at my back, but I continued slamming into her, driving her to even greater heights. Her pussy clenched with every wave of orgasm, the time between steadily growing longer until at last, her arms went slack and her legs fell limp.

“Thank you,” she gasped after a few seconds and then went into another brief fit of shuddering.

“You’re… You’re amazing,” I said, still buried to the hilt in her embrace.

I pushed up onto my arms and the movement of my cock inside her must have set off an aftershock, because she yelped and lurched, causing me to slip out. I simply sat back on my heels, marveling at the sight of her in the afterglow of her orgasm and just smiling like a fool.

Her eyebrows twitched up when she saw my dick coated in her juices. She sat up and rubbed her fingers through the spatters of pussy nectar dotting her skin, and running into the crack of her tight little ass

“You didn’t come,” she said.

I shook my head.

“You want to fuck my ass and come inside it?” she asked seductively.

It was my turn to shiver at the thought of that.

Monica grabbed her legs and pulled them behind her head, pushing her ass forward. That was all I needed.

“Mmm,” she moaned as I scooted forward, aiming my cock at her rear entrance.

She gasped when she felt the tip press against the iris of her ass.

“I want it. Please,” she begged.

I put my thumb over her clit as the head of my cock pressed against her back door. I pushed, and she groaned. Her eyes shot wide open and the groan turned into a squeak when the head popped inside her ass.

“Okay?”

“Uh-huh,” she answered.

I rocked my hips slowly while running my thumb up and down her nether lips, and she squealed. I pushed even deeper, and she peeked up over her breasts to see half of my erection buried in her back door.

Though I kept the pace moderate, I was truly fucking her ass and I watched her breasts quiver as I built up to speed. Now fully stretched, accepting the invader plundering her forbidden canal, she soared rapidly toward another climax, crying out as my cock vanished into her depths, balls slapping against her skin.

“Give it to me!” she cried out, her voice rising into a scream as an even more powerful wave of orgasmic energy swept through her.

I roared as the tight squeeze and her words summoned up a wicked itch in the head of my cock. It swelled and spread rapidly as I slammed into her and grunted uncontrollably. After only a few more thrusts, I was teetering on the edge.

Monica had the most amazing look of wide-eyed anticipation on her face when she said, “Yes! Do it. Come in my ass.”

I let out a long, loud, rumbling growl as my hands moved beneath her, and lifted her from the couch. I slammed into her one last time and erupted like a volcano into her little ass. My hips bucked spastically and a shamefully high-pitched sound emerged from my throat.

“Oh, I feel it throbbing. Fill me up,” she encouraged me.

That was a request I had no trouble fulfilling. Cum surged up my shaft and spurted so hard into her depths that it felt more like peeing than cumming. Over and over again, my cock pulsed, pumping cum into her tight canal.

She let out a soft moan when my trembling hands let her drop back to the couch and my cock slipped out of her now gaping ass. Monica giggled when I collapsed limply against the back of the couch.

I looked up through heavy eyes when she moaned and saw her dipping her fingers into her cum-filled ass and examining them with an expression that mingled amusement with just a touch of disgust. My cum immediately began to seep out of her red and gaped hole, and she whimpered at the relief of the cool air kissing her hot, tormented flesh.

“I can’t believe how hard you made me cum,” she said smiling.

“You’re amazing,” I whispered, trapped in her mesmerizing green eyes.

“I should probably get in the shower,” she said and scooted to the edge of the couch

Monica gingerly made her way to the bathroom, cum still dripping out of her ass. I watched her go inside and close the door behind her. When it closed, I pinched my arm to make sure I wasn’t dreaming.
