I was about to go in the bathroom when I heard some weird noises coming from it, when I opened the door I found my step-sister, Riley, playing with her Hitachi. Riley had no idea I was home and freaked out dropping her toy to the ground and covering up with a towel. She must have been really horny cause she started to come on to me, I can not believe this is the chance I have been waiting for to fuck my step-sister's tight pussy.
