A married man's long-held fantasy becomes reality when his wife's stunning younger sister agrees to a night of forbidden fun.

I (Josh, 27) am a reasonably happily married man, who has a very attractive skinny brunette wife - Sophie (25) I am very fortunate she has a great sex drive and generally there is nothing wrong with our relationship or sex life.

However ever since I have met Sophie 4 years ago there has been one problem... Claudia

Claudia was Sophie's younger sister, petite, and absolutely stunning. She had the perfect ass and the kind of breasts that were just the right size.

We had 'flirted' over the years. With me commenting over how good she looked and how ANY man would want to fuck her, I even talked to Sophie about how hot her sister was. I had spied her in underwear, and swimming was always fun, with lots of accidental touching. But never anything sexual.

Having not seen Claudia for a few weeks I asked Sophie if we should have her round (some stories here had got me confident) for a piss up night. Fortunately they both agreed. We also agreed to dress up. Sophie looked great in a tight red jump suit, and to be honest any over night I would have been all over her, but that was not my goal.

Claudia wore this short black dress, it was shear and I could see a black bra under it, that kept my hard over dinner and first few drinks.

After dinner the alcohol was flowing freely. Sophie was already feeling the effects of the booze and decided to call it a night, with some encouragement from me. I watched her sway her way up the stairs, a smirk playing on my lips, as I knew what I had planned. This was the moment I had been waiting for, the chance to finally have Claudia all to myself.

I turned to Claudia, who was sitting across from me, her eyes sparkling from the alcohol. "So, Claudia, now Sophie has gone to bed, are you ready for some fun?" I asked, my voice low and husky.

She bit her lip, a smile playing on her face. "What kind of fun did you have in mind, Josh?"

I leaned in closer, my gaze never leaving hers. "The kind of fun that involves you and me."

She paused, looked at me as if checking and then her eyes lit up as through a very cheeky grin she said . "I've been waiting for this moment for a long time, Josh."

I was shocked, after 4 years finally realising she wanted the same thing. I didn't waste any time. I stood up, holding out my hand to her. She took it, and I led her up the stairs, my heart pounding in my chest. We slipped into the guest bedroom, the room bathed in a soft, warm light.

I turned to Claudia, my hands already reaching for the hem of her dress. She didn't stop me, instead, she helped me pull it off, revealing her lacy black bra and panties. My mouth went dry at the sight of her, her body perfection in every sense of the word.

"Fuck, Claudia, you're beautiful," I whispered, my hands already tracing the curves of her body.

She moaned softly, her hands reaching for the buttons of my shirt. "I want you, Josh. I've wanted you for so long."

I didn't need any more encouragement. I pulled her into a passionate kiss, our bodies pressing against each other. I could feel her nipples hardening against my chest, and it only served to make me harder.

I broke the kiss, my hands already unclasping her bra. I pulled it off, revealing her perfect breasts. I leaned down, taking one into my mouth, my tongue flicking over her nipple. She moaned, her hands tangling in my hair.

I moved lower, my hands hooking into her panties and pulling them off. I spread her legs, my gaze fixed on her glistening pussy. I leaned in, my tongue tracing her folds. She tasted sweet, like honey, and I couldn't get enough of her.

She moaned, her hands gripping the sheets. "Oh, Josh, that feels so good."

I didn't stop, my tongue moving faster, my fingers joining in the fun. She was writhing beneath me, her moans growing louder. I could feel her pussy tightening around my fingers, and I knew she was close.

I pulled back, my eyes meeting hers. "I want to be inside you, Claudia. I want to feel you cum around my dick."

She nodded, her eyes filled with desire. I positioned myself at her entrance, my eyes never leaving hers. I pushed in, her pussy tight and wet around my dick. We both moaned, the sensation overwhelming.

I started to move, my thrusts slow and steady. She met each one, her hips moving in time with mine. I could feel her pussy tightening around me, and I knew she was close.

I reached between us, my fingers finding her clit. I rubbed it in circles, my thrusts growing faster. She moaned, her body tensing beneath me. "Oh, Josh, I'm going to come."

I didn't stop, my thrusts growing more frantic. I could feel my own orgasm building, my balls tightening. I thrust into her one final time, our bodies shuddering in unison. I could feel her pussy milking my dick, and it only served to prolong my orgasm.

We lay there, our bodies slick with sweat, our breathing ragged. I looked at Claudia, her face flushed, her eyes filled with satisfaction. "That was amazing, Josh," she whispered.

I smiled, pulling her into a kiss. "It was, wasn't it?"

She nodded, her arms wrapping around my neck. "I want to do it again."

I chuckled, my hands already reaching for her. "I thought you'd never ask."

And so, we spent the night exploring each other, our bodies becoming one in a dance as old as time itself. It was a night I would never forget, a night of passion and desire, a night of Claudia.
