She wasn't particularly beautiful. Hair long and dark and straight, eyes wide and dark, her lips kissable. I mean don’t get me wrong – I never intended to end up in bed with my friend’s girlfriend - but these things happen.

I’m not entirely sure how it happened but we weren’t drunk. There were four of us - two girls, Joe and another guy I didn't know. Us girls were being particularly flirty, our skirts short, our shirts tight and…well, we weren’t wearing any underwear, despite it being a cold day.

To put it bluntly. We were all talking about lesbians – about how real lesbians aren’t pretty, they’re butch - or so we thought. How you never see girls kissing each other and really being attracted to each other when they’re sexy. And then she kissed me. The guys were pretty horny, I’m telling you. But she made me leave them to watch dirty movies or whatever it is they do, and led me upstairs to “do girlie things”. And honestly – I didn’t guess what she meant. Or at least not until she shut the door, pushed me against it and shoved her hand up my skirt whilst kissing me.

It’s not everyday I get into a situation with my knickers round my ankles and think “I’m actually enjoying this, and it’s not a mistake…and I’m not drunk so I’ll remember it tomorrow!” Granted, it’s probably classed as cheating but what did I care?

She wasn’t gentle – she was horny and she wanted it. She pulled me onto her boyfriend’s bed and she was stripping me naked, while my hands flew to her shirt and pulled it off. We sat up, her body presssed against mine, kissing me, her tongue exploring my mouth – tasting, licking. Her teeth nibbled my lips, her mouth open and moist to mine. I could feel her hand snaking their way to my pussy, her fingers stroking me, exploring.

I bent to her breasts and sucked her nipples, biting them, licking them. We were both moaning and panting, hot and wet. She pushed me down on the bed and began to work her fingers inside me, then her tongue followed. I can honestly say it was the best I’ve ever had – she knew everything a girl wants.

She sucked my clit and licked my pussy, trailing her tongue from front to back. She moved her fingers inside me, pushing upwards and finding my G-spot quicker than any guy. She rubbed it, making me moan even louder, her tongue still flicking my clit. I arched beneath her, pulling at her hair so she buried her face in my pussy. I came loudly and she laughed delightedly, moving up onto me to kiss me. She tasted of me and I relished it.

But I was curious to know what she tasted like. I loved it - loving to taste every bit of her, to savour her sweetness, to fill my mouth with her. We rolled over so I straddled her and after kissing my way down her body, I began to slowly lick her. She was horny as hell, and so wet.

My fingers slid easily into her – 1,2,3. She bucked her hips, unable to restrain herself as I pinched her clit. She pushed down hard on my hand so I reached her G-spot and as I continued to lick her, she came. She moaned and arched her back, pushing her breasts out like I always do.

I thought that’d be enough for her. After all, any guy I’ve ever been with has one orgasm then rolls over and gets dressed or falls asleep. But she was like me, with an insatiable appetite. And god, I wanted her. I admit I’ve found women attractive before, but finding myself having just given one an orgasm was a whole new ball game.

She wanted us to do 69 style. To be honest, I’ve never been able to concentrate when someone’s licking my pussy and then was no exception. I straddled her and leant so my pussy was above her mouth, then bent to lick hers. She was so good – even tho her body was shaking from the orgasm building up inside her, she kept licking me. I couldn’t concentrate; her tongue kept probing me and flicking my clit. We came at more or less the same moment, in a loud, messy explosion. I rolled off her and collapsed, my mouth full of her, my pussy dripping and still burning hot, reeling from the touch of her tongue.

I wriggled round and kissed her, my hand on her waist, slipping to her ass. She did the same, pulling my hips closer to hers until they touched. We sat up and wrapped our legs round each other, our pussies exposed. We writhed closer to each other, still kissing, until they touched, hot and horny.

It was at that precise moment that the boys walked in. The look on their faces were priceless.
