I was turning 35 and my girlfriend, Anne, had invited four other couples to come celebrate. We'd rented a large house an hour outside of London. It was the typical country mansion with many rooms and corridors and large elaborate grounds. Everyone showed up with numerous bottles of wine, whiskey, vodka - you name it. The food was catered and delicious. We all had a great time and far too much to drink. The first to go down was Jessica, the petite Asian girlfriend of Geoff, a mate of mine from Uni. She complained of being dizzy and needed to lie down. Anne told her to just go upstairs and pick any room -- there were far more rooms than couples after all and no one except us had put their bags away.
Anne, was the life of the party. Blue eyes, blonde, pale skin, tall, and buxom - she was just about the polar opposite in looks from Jessica. When I walked down the street arm-in-arm with Anne, I could just about hear the "luck bastard" looks from all the men and women we crossed paths with. We'd been going out for five years and at my age of 35, and her's at 30, it was time to start thinking of getting married. Anne was putting no pressure on, which was part of the reason I adored her, but it wasn't right to string her along and I'd secretly been making trips to a jeweler friend of mine to design the perfect engagement ring.
Anne was like most English women, able to drink with the best of them, and it wasn't long before we were all legless and stumbling around. Anne bowed out next and hauled herself up the stairs. The rest of the couples headed up shortly thereafter to find a spare room and a bed to collapse upon. I made sure to lock the front door, close the grate to the fireplace, and turn off the lights before staggering myself up to our room.
Not wanting to wake up Anne, I didn't turn on the lights and quietly brushed my teeth in the adjacent bathroom, changed into pajamas and climbed into bed. It wasn't long before two arms reached out to me and we started making out. Being somewhat inebriated I barely managed to pulled down my pajama bottoms, while Anne shimmed out of her clothes. Neither of use spoke a word -- the need to fuck was too urgent. Within seconds I was balls deep in a wonderfully tight and wet pussy, giving me excruciating pleasure. I was in heaven. It only took a few minutes before I emptied a bucket of cum into her. Then we moved into our regular cuddling position, spooned together. To my surprise, instead of the generous handful of D-cup tits that I was used to, I found a small B cups worth. Then when I reached down to fondle her bottom I found a pert muscular version rather than the plump soft one of Anne. Even in my foggy state, it was becoming clear that I had just shagged someone other than my girlfriend. That someone had to be Jessica since she'd gone up earlier and all alone.
I was both appalled and extremely turned on by this turn of events. I was supposed to be in love with Anne, a woman who I was buying an engagement ring for, for fucks sake, but instead all I could think about was Jessica and the huge crush I had always had for her since we met over five years ago. The truth was that I had a thing for petite Asian women and dominating them in bed. Something I'd manage to push out of my mind by staying faithful, at least until now, with Anne. And Jessica was a prime specimen of my "type" -- younger at just 25, petite, nice small handful of tits, long dark hair, trusting caramel brown eyes, and a rounded muscular and firm behind. Also, she was just a wonderful person: funny, outgoing, generous and kind, smart and good at her job -- some sort of prop trading in the City of London.
What was I to do? I knew my girlfriend was probably collapsed out on some other bed. I felt compelled to keep everything secret from Anne. It was an accident after all. So I whispered into Jessica's ear: "Jessica"
"Ummm" she replied.
I thought I'd best be direct: "It's John, I guess you got in the wrong bed."
"What!" she cried out.
"I thought you were Anne" I said trying to defend myself.
"Fuck. We just had unprotected sex and you came inside me." said Jessica.
I'd heard via the grapevine that Geoff had a problem with his swimmers and that was the main reason why Jessica and him were just friends with benefits and nothing more. Guess she didn't need to use contraceptives.
