Fuck her instead

Mind control, eh? Instead of taking off my shirt, how about I fuck you instead?

Suddenly, you can sense a change in your sister.

Katherine, take off your panties and lie down on your bed.

Katherine complies. She spreads her legs and gives you an eager smile.

You walk up to the bed and lie down on top of your sister. As she pulls you into a passionate kiss, you thrust your erection into her eager pussy. With each thrust, you can feel the pleasure rolling off of her, encouraging you to go faster and thrust harder.

"Mom's right," Katherine gasps in between moans, "you have grown, Benji." She runs one of her hands through your hair, as the other hand caresses your back.

You're about to respond, when something seems to push you into a daze. When you come out of it, your head is lying on one of Katherine's shoulders. She's breathing heavily and a warm wet feeling around your limp dick lets you know that you came inside her.

As your mind clears, you hear a sigh behind you. You turn around to see your twenty-four year old cousin Natalie sitting in your doorway. She's barefoot with her shorts and panties around her ankles, and it appears that at one point she'd sat there and started fingering herself.

"Hey, Natalie." You walk over to her, kneel down, and kiss her forehead. She smiles shyly and looks down at your crotch hungrily.
