Fill that ass!

You continue to slide your swollen cock head to balls, head to balls in her tight ass while you orgasm. You can't help but shudder, too, during such a furious climax. The whole while you feel yourself spouting huge gouts of cum with every thrust, deep into her rectum.

It's truly a biblical flood of semen, furthering your suspicion that Blowjob Universe has bestowed you with divine testicles. In fact, it's almost as if your orgasms GROW in volume each time you wreck a girl, instead of tiring and running out of juice, literally. You look forward to this prospect.

Six thrusts, seven thrusts... by this point there's very little space left insider her, and cum gushes through the seams between your dick and her sphincter. Eight, nine... at last, on the tenth spout you're finished, and release your deflating cock from her gaping red asshole. As you lift her up by her perky asscheeks, the remaining cum pours out onto your stomach, dick, and balls.

"Jesus fucking Christ that was the hugest orgasm I've ever had!" you exclaim.

"No kidding you motherfucker, I can still feel a bunch of it inside me. Fuck, my ass is gonna be sore for days! My throat hurts too, it feels like I have strep!" She never stops complaining. Younger siblings are always so annoying...

"It's not over yet, fuckhole, Tommy still gets a turn with your perky butt!" you remind her.

Tommy doesn't look as enthusiastic, though. "Aww man, I dunno, I don't want your sloppy seconds..."

You admit, the thought of fucking a hole lubed with another man's jizz IS a little off-putting... Maybe someday in your eternal sex-themed afterlife, you'll give it a shot, but for now it doesn't seem fair to expect Tommy to go for it.

"Oh whoops, you're right, sorry. C'mon Sis, get your fingers up there, wipe yourself clean for Tommy." You remember your crotch is still coated in your own cum as well. "And while you do that, lick this mess off me, too." You take a handful of her hair and **** her still-sloppy face toward your dripping cock.

"Oh Hell no!" she responds, trying to wring free, "if keeping a load of YOUR JIZZ up my ass is what it takes to keep HIS DICK out, I'm all for it."

"C'mon guys, I'm getting anxious here!" Tommy whines petulantly. Strands of Rachel's gack slime still hang off his rock-hard, throbbing, and as-yet unsatisfied flagpole. It looks sufficiently-lubed to start fucking any hole of his choosing.

Just then, you hear a car pull into the driveway. You realize you have no idea what time it is. Time really flies when you're brutally fucking your kid sister three times in a row! Perhaps it's your stepmom Claire, on lunch break? Or back from work? Boy, she'll probably be pissed about the mess you've made... and the whole **** thing. Hopefully you can just blame it on Rachel; it's HER puke, after all, and her perky teen body is just too irresistible!

You weigh the options: if Tommy really wants to stick with Rachel, you're sure you can find a way to punish her for being so uncooperative. Then again, if Claire's home, you know from experience that she's down to fuck. Plus, you still haven't broken-in your older sister, Melanie.
