My last GF i met through my younger brothers friends. I was 26 and my younger brother was 23 and living with me at the time, we'd have parties every weekend and his friends ranged from 18-24, i stayed away from banging the women in his circle but we'd had a party one saturday night, had the sauna and hot tub going and finally called it a night around 2am, she had just turned 19 i'd seen her around a couple times but never actually talked to her, she was cute, decent body, nice DDs brunette hair and brown eyes and i'd heard from a few guys she knew how to suck a cock. Anyway we call it a night and i head inside to have a shower before going to bed, everyone had passed out in the living room or the spare room, i finish my shower and i get out dry off and hang the towel up when all of a sudden the door opens, she was clearly drunk we just looked at each other, she was a bit shocked and immediately apologizes and says she really had to pee and didnt realize anyone was else was still awake then she takes a long hard stare at my semi hard cock then closes the door and leaves, i thought it was pretty funny and called it a night, she was gone by the time i woke up.
The following weekend we had people over again, she showed up with one of my brothers buddies and his GF, again we wound up getting drunk in the sauna, as the night died down it was The buddy/GF, me and the ex left, the buddy and his GF got up and said they were done for the night, she says they are her ride so she should probably go as well. It had only been a couple minutes, i was finishing my drink when she comes back in and says "So those two are fucking in the car so i guess i'm not leaving yet" then sits down right next to me, she gave me a look, i made a move and we started making out, after a few minutes though she broke the kiss and basically blurts out "Ok i'm just gunna say it, You've got a REALLY nice cock plus it looked big and you weren't even hard!" , i laughed and asked if she wanted to see it again, she eagerly nodded yes and i pulled it out, within seconds she was naked and on her knees in front of me, the rumors were true she was and still is one of the best blowjobs ive ever had and to top it off when i told her i was about to cum she didn't even slow down she just kept sucking until i blew my load and she swallowed it all, we fooled around a bit more then went inside, i fucked her once in the shower then we fucked a few more times before passing out. I woke up the next morning to her sucking my cock again, then again pump a load into her mouth and she swallowed it all with a smile.
We ended up dating for like a year and a half, I was her first for a few things, first older guy[more than a year or two older than her], first big cock, first guy to go down on her, first threesome, she was an absolute nympho, we'd fuck everywhere and anywhere, but ultimately the sex was the only thing we had in common and we had different priorities in life so i broke it off.
