'Lets see. Your step sister catches you jacking off using the panties that you borrowed from her room and she then stays to help you finish. You then ...help her because she had gotten hot watching and helping you. You touch, kiss and lick her breasts while she does herself.Today you wear a pair of her panties while she rubs her hot silk covered pussy along the length of your silk covered cock. You wind up banging the hell out of her because the masturbation wasn't enough. Yeah, that about sums it. "Mark, damn you Mark, FUCK me."He cast any thoughts of going slow to the winds. His hands gripped my hips, still a bit generous, regardless of morning PT. He pulled back until only the head was still lodged in my ass. Then he rammed deeply into me. I squealed. He did it again.

Jack swallowed and stared at my chest. His mouth.

We’re both trying to catch our breaths as her cum slowly oozes out of my ass. I’m left speechless. “Babe, you know, we don’t have to pretend to be a couple. After a fuck like that, I would love to have you as my cute little boyfriend.” I roll on my side to face her..
