I took a seat on the couch next to her to watch. She played and I just watched, and we started talking about whatever came up. First about the game. S...e was getting pretty pissed because she kept dying at this one part, and I was laughing at her."Will you shut up?" she said."Nope," I said, still laughing."Fuck you," she said as she died in the same spot for the thirtieth time. "With a ten inch dildo."I laughed hard."You'd know." I blurted.I know I shouldn't do stuff like this, but I always. "I was almost relieved. "Look. Let’s forget the whole thing. I’ll just go outside, so you can finish in private. I won’t be able to hear you with the windows closed." No. No. Wait. I was getting close a few minutes ago, but then I lost it. Let me try again."She kept at it, but now she wasn't even beginning to breathe heavy.I interrupted her. "Susan...”"Yeah."“...just not happening. Is it?" No. Maybe if you went first."A lightning-bolt of panic ran through me. I was still unsure about letting. I had a piss in one of the cubicles but when I came out there was this older boy by 2 years who stood in front of me and with this huge cock and balls outside his trousers. It was absolutely huge and the head was exposed and it was so hard and purple. He rubbed it a few times and all his mates laughed at my expression and he said well what do you think of that then?I was shocked but I must admit I was fascinated and that night in bed I wanked at the thought of it and produced cum.I was. This time I moan and groan but no words. I start breathing harder and faster and think to myself " I'm gonna cum in her mouth!" And within seconds I spurt and spurt and spurt. I think she will immediately take my cock out of her mouth and be pissed but no, she holds me in her mouth until I'm finished cumming! I'm in ecstasy and can't put a sentence together but she gets what I'm trying to say. She drooled my cum run down my cock and balls. Swallowing would have been the icing on the cake but.
