You really left your door unlocked? You're lucky it was just me.. and not our parents.. Please don't stop just because I walked in. I'm only your step sister. Not like we're actually related. Aww thats cute, you even have tissue next to your bed for "cleanup". Please go on.. I wonder what you think about when you masturbate, haha. I think you could use a hand, you should pull it out, don't be shy. Yeah, just like that. Do you like when I do this? Does that feel good?
