4 and a half months ago, I visited my cousins house. So they don't get into trouble, lets call them Chloe and Cara. One night, I (ahem) was having a dream involving a girl giving me a blowjob, and I ended up being awoken. What I found shocked me. My cousin Chloe, was actually giving me head! With Cara watching! Now I am a nerd, so I was repulsed at first, but then realised "Hey, Frank, this may never happen again. Don't spoil it." So she continued until I...well, you can guess. I moaned, catching their attention, but quickley rolled over to cover this up. "And that" said Chloe to Cara "is how to suck a boy off". "Wow!" said Cara. As they left, I heard Cara ask Chloe, "Hey...you'll do it tohim... Why not your sister?" I couldn't see anything, but I heard it all. Moaning, sucking, and squeals. I confronted them the next day, and told them, and they burst into tears. I told them it was alright, blah blah blah...Now Cara is trying! Shouldn't they stop? I mean, Cara is 7, and Chloes 9! Is it normal for them to be this sexually active?
