I catch my brother spying on me while I'm in the bathroom getting ready to go on a date with my boyfriend. I snap at the pervert and threaten him that I'll tell mom what a sick son she has. He keeps apologizing and begs for me not to tell her. He says he owes me and he will do anything for me . Since I'm planning to give my new bf ours first BJ, I ask him a few tips in exchange for my silence. He then suggests that I can even "try it on him" to gain some experience, ewww! No way. Ugh, but I don't want to embarrass myself and ruing this >.< Fine, I think this is the best option. He gets it out and I'm surprised at the size of my brother's cock O.O I start sucking my brother's cock and ask for his feedback. He then tells me to open my mouth so he can cum in it. -------- [real dialogue between the 2 of us]
