My sister Maria Marley just had her nails done and they are supposed to change color with her mood. This isn't working so she calls me in to see if I can help warm them up. Nothing seems to work as Maria even tries to put them into my pockets. My sister has teased me like this before and I see that she has candles and lube out on her nightstand. As I try to leave my horny sister lays me back down and starts to take off my pants. She is convinced that stroking my cock will change the color of her nails. Maria uses both hands to jerk me off and massages my heavy balls before I bust a huge load into the air and onto her hand. She is happy with having cummy white colored nails.
