Had a based sex dream where my sister was 9 again but I was still old and she was rubbing on me in hed and I was BEHAVING but couldn't help getting hard and I thought "it's not bad as long as I don't rub it on her!" so I didn't move but let her keep crawling all over me, and then she felt it, and got interested and was smiling, and she could tell I was powerless, and she rested her head on it and said in a playful child voice "Oooohhhh (like I've been naughty for an involuntary response!) it's getting hard >:3 " and then I was frozen, I didn't know what to do, but the I said FUCK IT and we started making out gently and rubbing and she started pulling it out and I was helping her by pulling my pants down...then my STUPID Mom walked in, and we had to pretend nothing was going on, but then the bitch left and we started making out again and were practically having sex when I woke up all groggy confused where my good little sister had gone then I remembered I live in the real world where I have a bitch little sister who never was a good little sister who helped my pp /vent
