Make her deepthroat

You cant help thrusting it all in. You put a hand behind and push her head in as well. Your dick hits the back of her mouth. She opens her eyes and sees you on top of her. She blinks quickly.

"Mmmpph"she makes out. You push your dick down her throat. It feels so wet and warm. She gags. You pound her face harder as she tries to push you away.

"Mmmmpphh"she cries, gagging again. It feels so good. You look at your beautifuls sisters face, her lips struggling to wrap around the base of your dick. With your hand in her soft hair you keep pounding her face. You feel a familiar feeling as you know you're gonna cum soon.
