As we were both standing there completely naked, Derek with a towel in his hand I noticed a stir in his penis. A slight twitch. We were both getting a...oused and you could see it in our cocks. That was the first time that I looked at Derek in a sexual way, his slim build, rock hard abs and little patch of trimmed pubic hair. At 12 I still didn't have any and I had a pretty feeble penis, at about 4" fully erect it was tiny in comparison to Derek's ever growing cock. Without speaking he reached. E till oral sex but never full penetrative sex.I was getting desperate which forced me to find potential girlfriends or flings on the internet. I used to frequent chat rooms and try to chat up girls which would lead to online sex or something of that sort, but this was not enough. I needed to break my virginity. I was casually surfing the internet when I came across Craigslist – a website which offers anything and everything- and I found an ad there, that a couple was seeking potential males. I stood up walked behind her, I bent her over at the waist she moaned and said “Take me as roughly as you can, I love it like that” I then shoved my hard cock deep into her cum filled pussy and started fucking her really roughly.Peter was getting hard watching me fuck her very roughly this got him fully ready as I fucked her from behind. Peter stood up and stood in front of her taking her head in his hands and shoved his erect cock straight down her throat making her gag a little, he then. Wondering who Lady Sarah had invited? Still convinced her going out was just a tease to arouse my submissive nature. But, then there was a shock that would have made me run from the room, if I had not been so well trained (more than I realised) by my wife.“Hi Sarah....see you have your dirty gurl ready. Your Dad and I will take good care of her.”“She looks very nice....I’m guessing her ass is plugged already?”“Of course it is Dad.....getting nice and ready for you.”There was laughter shared.
