Hey guys, its Kim. I tell my brother about gym exercise....You won't believe what happened - or maybe you will;-) I got back from the gym yesterday and went in my room. He got in my room and jumped up on my bed and started showing me how to stretch muscles - I think he's pretty cute. I popped his fat cock in my mouth and started blowing him. My little brother was freaked out. I sucked and jerked my brother until he was on the verge of cumming and then I told him to fuck me. He definitely needs more practice because he was about to cum after just a few minutes. I yanked his cock out of my pussy and told him I wanted to see it. He cumm all over my face...My little brother asked if we could practice again sometime and he gonna be at his room - I told him of course, that's what sister's are for.
