Stay With Your Sister

You decide to stay in the living room and see what happens. On the TV, the eponymous slutty schoolgirl is now totally naked, displaying her pussy and big tits to the camera. It's hard to keep your eyes on the action as they're drawn to your sister less than a foot away. She's watching the porn intently, absentmindedly touching herself, tracing the plump pillows on her chest and lightly grazing over her barely-covered crotch. Your erection is as hard as it's ever been and you're barely restraining yourself from pulling it out, but afraid of how she might react. Her fingers slip past the waistband of her shorts, surely touching her pussy lips, as she bites her lip just like she used to do when she did her math homework with you. Suddenly the actor on screen is pulling down his pants and the slutty schoolgirl is on her knees taking the massive cock into her mouth. Your sister turns to you and you lock eyes. You know right then that this is the moment of no return.
