You give Franklin a choice.

"So," you ask suggestively, "which do you want?"

Franklin is rearing to go. An erotic display of pure shameless sexuality by his own kin has him in a frenzy, ready to go again. Almost shoving you aside, he claps his hands onto Beth's ass and reels her in for himself. Emma reaches back and opens up her pussy lips with two fingers, telling you it's time to do the same. You, Emma, and the siblings are fucking side-to-side, racing to climax like horses at the track. Franklin's fat meatstick is stretching out Beth's delicate pussy, and he pulls her hair back so that her moans escape loud and clear. Emma swivels her head and gives Beth a sloppy kiss, almost missing the mark from how much you're all pounding away. Emma is muttering to Beth about all the ways she can fuck her brother.

"From behind, in your mouth, against the wall, up your ass-- Hey!" She protests for a moment as you roughly pull out of her and tap Franklin's shoulder. You point from Beth to Emma and back again, and he picks up on your idea. You shift over to kneel behind Beth and Franklin does the same for Emma. Beth grinds up against you as she takes a deep breath and slides all the way down your length. She's so sopping wet that even your huge dick can get all the way inside of her. She squeals. She's becoming a complete animal, just like Emma, and you feel like you aren't far behind. She moans in pure bliss as you put her pussy to work. Next to you, Emma starts a long, low moan that ticks up in register until she's screaming in delight. Franklin grunts like a barbarian as white fluid escapes from Emma's pussy, he's cumming deep inside her. Beth starts cumming on your cock, shrieking in harmony with Emma, one bitch teaching another. Emma gyrates on Franklin's cock as they take a breather, but you keep bucking and thrusting into Beth, until you feel her body start to quiver a second time. With an ear-splitting scream, she has a second orgasm and collapses in a heap. You jerk yourself to completion and paint her backside, cheeks heaving as she gasps for breath.

"Shotgun orgasm? John, you're such a stud."

The fireworks have ended, for the moment, though the show has only begun. In the brief quiet as everyone recovers their energy, you hear it again, the same as last night. The other tents around you are getting rowdy, too. A chorus of moans and cries for more, people masturbating, fucking themselves with beer bottles and toothbrushes, anything on hand. The sounds of sucking and licking, bodies sliding and rubbing together, coming from all around you. It's hypnotic and you suddenly realize you're in the middle of a campground orgy, happening all around you. There's got to be dozens, maybe over a hundred people all listening to you and getting horny. The smell of sex hangs in the breeze. Here in this tent, on this campground, you and Emma are sex gods, immortal avatars of arousal, and these are all your worshippers, Beth and Franklin your chosen disciples.
