My first threesome didn't go exactly as i'd foreseen it would, but better than i could have imagined it would. It all started with my then wife's friend (K) we had been flirting with each other and the odd fondle when we thought we wouldn't get caught but that all changed one night when we met up in quiet car park in her car, within minutes of getting in K's car she was all over me. I wasn't complaining as she kissed me and started undoing my jeans and as she put her hand in my shorts and wrapped her fingers around my rapidly growing hard on she stopped kissing me, looked me straight in the eyes and questioned whether i really wanted to do this, my nod and grunt was all she needed to proceed. She started kissing me again and running her fingers lightly up and down my cock and running her finger tips across the tip of my cock teasing my precum back under my foreskin before pulling it all the way back fuck this felt good and i let out a moan of approval. Things then moved up a level, unbeknown to me in my state of arousal and as my eyes were closed to the world i hadn't noticed anything going on as K pulled away and moved down and started to slowly suck my cock in time with her wanking me, i briefly opened my eyes as she wiggled about hitching her skirt up and wiggling out of her knickers, nothing untoward to be seen. after only a few minutes of K sucking me off she clambered across the centre of the car held on to my raging cock and lowered herself onto me, slowly taking every inch of me inside, just as she'd ground herself all the way down and pinned me to the seat, she stopped and whispered very softly that this was one of her real fantasies, i opened my eyes to look into hers just to agree and just as i did the car door opened, the interior light came on and there was this guy (who turned out be K's friend) standing there with a massive hard on glistening in the light, to say i was shocked was an understatement but not quite as shocked as when K asked if id suck his cock while she fucked me as this was her biggest ever fantasy. Let me tell you being a straight guy, being deep inside a woman and having a big hard cock that close to your face is more of a turn on than i could ever have imagined it would be. K sensed my shock and started to kiss and grind herself down on me and wank him off at the same time, K pulled him closer and rubbed the tip of his cock across my cheek towards my mouth, as she wanked him i could smell the musky scent and feel the wet sticky precum dripping from his cock onto my face then the wetness was on my lips, i stuck my tongue out and sort of licked the precum off not quite sure what i should do really, one of my thoughts was that this wasn't to bad actually and maybe i should just enjoy it. Didn't take long for K start trying to force his cock in my mouth i must have just opened my mouth and started sucking just as i like being sucked off i suppose, after only few minutes he pushed K's hand away and started to wank himself off into my mouth, i new what was coming next, his cock grew to a size that i could only just get in my mouth and with a huge groan and a thrust that nearly chocked me he forced his cock in to the back of my mouth and came, he came more than i think i ever have the first burst went straight down my throat the next few bursts filled my mouth and he carried on thrusting and wanking into my mouth forcing it down his cum down my throat, K by this time was squealing and moaning and coming all over me, i couldn't take any more of this and just as i tensed up and emptied myself deep in her she just slumped forward and started to stare at me licking his cock. We sat in that seat for what seemed like an age K still on my lap with my cock in her and this guy with an incredible ability to keep a hard on slowly wanking himself over the two of us, his cock was quite impressive really i was a little envious of his ability to keep it up, i decided to take a bit of control pushed his hand away and took hold of his cock teasing the last drops of cum out, but instead of slowing him down his cock seemed to grow huge again and as i pulled his foreskin back to reveal a huge purple helmet he shot another load on my face. After the shock of the second cumming he pulled away and tried to put his still very erect cock away, K did help him out as she clambered of of me and as she stepped out of the car i caught a glimpse of him as he moved away from the car, thankfully i'd never seen him before, i was a bit dazed and confused as K car back to the car and whispered in my ear that that was the best night of her life and that i could try anything i liked to her from now on.
