Fuck Sleeping Katherine

You keep pounding into your fucktoy Sabrina and she suddenly orgasms, her legs going limp as she starts to shake. You hold her up in position and keep jamming your cock into her as hard as possible.

"Ohhhh, fuck, fuck, ow, ow, fuuuuuck" Sabrina says as she is overcome with pleasure. You don't let her have a break and keep fucking Sabrina as she tries to squirm away, her clit too sensitive for such a rough fucking as her orgasm dies down.

"If you don't want to get fucked, then your sister is getting fucked instead," you say, "Is that what you want?"

You can tell Sabrina is conflicted. She wants a break, her pussy now soaked and bright red from the beating it has taken. She doesn't want her sister to share that fate but she ultimately chooses to save herself. Sabrina nods her head shamefully and you push her off your dick immediately, letting her collapse to the floor.

You then yank her up by the hair, Sabrina yelping as you do so, and lay her over her sister's lap.

"You're going to stay there and feel the fucking your sleeping sister is about to take," you say.

You then line your cock up with Katherine's opening and push into her. She's tight. Very, very, very tight. In fact you can't get your cock into her fully. You wonder if she's ever been fucked before or if she's a virgin like Sabrina.

"Is your sister a virgin?" you ask Sabrina.

"I don't know," Sabrina whispers, "She might be but I'm not sure."

You pull back and try and push in again. You finally get your full length into Katherine and it feels like heaven. You start to slowly piston in and out of the sleeping teenager, admiring how Sabrina also moves with each thrust as she lays across her sister's stomach, blindfolded and tied, feeling her sister get unknowingly fucked because of her mistakes.
