Cum inside

You're too far gone to pull out now. You spank your sisters ass again and grab her hair, pulling it slightly as you cum deep inside of her pussy. You continue thrusting inside of her as you feel your cum dribbling out around your cock. As you pull out and get dressed you decide to do at least a little bit of clean up, with a paper towel you wipe her cunt before pulling her panties and pyjama bottoms back up before heading for the front door again.

You open the front door wide before starting time, and closing it behind you. You walk casually into the kitchen and find your sister with a strange look on her face as she continues pouring coke.

You: You okay sis?

Keira: Yeah.. yeah I'm fine.

She smiles at you as she finishes up with her coke and puts it back in the fridge, she then walks out into the living room with her glass. While she doesn't think you're looking you see her rub between her legs, and smell her hand. As she sits down that strange look is still on her face, she wrinkles her nose up at the smell on her fingers. You smile to yourself as you walk past her and head up to your bedroom.
