He was in bed with his girlfriend but he left the door wide open. His step sister wakes up a bit early and as she walks past their room, she sees them. Her brothers cock his hanging out of his boxers and she can't help but get turned on by the whole situation! He starts touching herself under and over her panties before completely removing them. She orgasms as quietly as possible before she just couldn't contain herself and went into their room. She touched his cock and he didn't awaken. She strokes it and then moves on to sucking him. It wasn't until she inserted his cock into her pussy that he woke up and was stunned. The sister shushed him as to not wake up his girlfriend. He silently lets her ride him until he cums inside her.
