Hell no! Your sister, your priority!

The prospect of giving Rachel a throatfucking as equally brutal as Tommy's definitely piques your interest, but you're far too absorbed in her ass at this point... metaphorically and literally. You can feel a massive payload of cum beginning to stir within your magical super-balls.

"No fucking way man, I'm riding this out to the end!"

"What the fuck, dude? You told her I'd get her ass again!"

You continue jackhammering your sister's ass while you argue with Tommy. "You got her ass when we DP'd her last time, you get her pussy this time." You flip over onto your side to give him better access.

"Gross, man, I'm not getting in there with that mess!"

The fact that Tommy could be so rough with your kid sister, but afraid of a little slop, is sort of ironic. "Your loss!" you retort, and begin humping her double-time, tucking your arms tight around her waist as you both lie on the bed, spooning. Her head still rests in the puddle of drool and puke, her face a sloppy mess. She can't even open her eyes, and fluids sputter every time she exhales through her mouth and nose.

"Ah, ah, ah, ooh, ooh, uh, ah, eee," Rachel whimpers beneath a thick glaze of gag juice, as you pummel her perky butt with your full 10-incher. Suddenly she starts to shudder and squirm. "Eee, eee, ah, ah, AH, OH, OHH! OHHHH! HMMMMNNN!" she moans, convulsing.

"Holy fuck dude, she just came from you fucking her ass, she wasn't even touching her pussy!" Tommy is momentarily distracted from being pissed-off.

"Oh yeah, you like anal orgasms, Sis? I KNEW you secretly liked getting your ass destroyed by fat cocks!" you taunt her.

"MMMMMMMNNNNH, MMMM, <gasp>, fuck you! <gasp>" she replies, still squirming. You feel her gushing wet pussy drip onto your thighs and coat your balls. She really DOES enjoy getting used, even if she won't admit it.

Just then, you feel yourself about to pop! "OHHH FUCK YES!" you exclaim, flipping onto your back and taking her with you, still hugging her waist tightly. You give her a few vigorous thrusts, and then the jizz fountain begins!
