No, not my cock, I'd been doing that for a few years when this happened.

I was 14 and it was a nice summer day and being perpetually horny I went into my parents room to get in to my dad's porn magazines (this was the 70's, no internet) and jerk off. I slipped off my shorts and was happily jerking myself to a good orgasm when the door to my parents room opened. Oh shit, I figured I was fucked and in super trouble getting caught by my mom or dad but no, it was my little sister (12)and her friend(13).

They thought it would be fun to catch me and see me jerking off. So, there I was, hard cock waving as I moved and pre cum dripping off the end of it and two girls giggling who can't take their eyes off of my dick.

My sister says they just wanted to watch me jerk off. I think about it and tell them that they can but........they have to get naked too. They decide that is fair and strip down too and get on the bed, reclined and legs spread wide. I had never seen a cunt before and now I had 2 of them to observe. I almost shot my load just seeing them, almost.

I resumed my wanking and told them to play with their pussies too, which they did. They were both already wet but they got wet enough that they were glistening. I couldn't help myself, I reached out and touched the friends cunt and ran my fingers up and down her slit and inside to the hymen.

That was all it took, I blew my load. I gushed and gushed the biggest load I had ever blown up to then. It went all over my sisters friend, from her legs to her chin. They must have thought it was pretty hot as both of them orgasmed after that.

All 3 of us had a lot of fun that summer, together and seperately. One or the other of them, or both, would come ask if they could watch again and being always horny and a gentlemen, lol, I obliged them.

I did finally fuck the friend but it was after she lost her v card but that is a story for another time.
