Don't ask me about how this all started but for the last year or so, when my brother and I are alone sometimes I let him finger my butthole while he Jacks off. I'll stand facing the wall, I'll pull my pants down to my knees and my bro gets up behind me and plays with my butt....for the weirdest reason when we mess around I get really turned on. He wants to do more but I refuse. One time while he had a finger in my butt he bent over to try to bury his face 8n my butt... it pissed me off....still, I felt his tounge for about 3 sec on my butthole and again, I kinda liked it. I really need to find someone other than my bro to mess with... by the way he's 13 and I'm 15 female
