Resting Sister Used Like Fuckdoll

Everyone in the house is resting, even my hot slutty sister. She's laying there wearing almost nothing and I can't resist anymore. I'm going to touch her and see if she wakes up... nothing. At this point I think she's pretending but either way I'm gonna see how far she lets me go. I start by feeling her up and putting my dick in her mouth, then my fingers in her pussy.... Now I'm putting my cock in, it's so warm and tight! I could blow my load now but I wanna enjoy it for as long as possible before she notices. I could cum anywhere, even her pussy.... I bet she will like it. A pleasant surprise.
