A misfire, but a pretty sexy one nevertheless!

"Fuck." Set grunted. "Give me your hot ass and I'll fill it up for you."
Alyxia shook her thick booty at him, precum dripping down her thighs. "If you want my butthole again, come and take it."
Set grabbed her slim, toned waist and pulled her backwards towards him. His tumescent swinging cock slid between her huge, tanned buttcheeks, glistening with a light sheen of sweat like it was oil in the blaze of the burning sun.

As he pulled Alyxia back into him, he felt his cockhead pop through her hole, forcing it to greatly expand to ridiculous proportions in order to accept his vast girth.
After Alyxia had let out a cry out in surprise, she turned her head back to glance at him inquistively. "That's not my butthole Set, that's my pussy..."
Set looked down. Oh. She was right. Guess it's not the first time that's happened, but he was sure...
"I'm not surprised you mistook it." She grinned, wriggling her ass back against him. "They are after all both hot, super tight and sticky wet inside." A couple more inches of bulging manmeat stuffed their way in, and her eyes half-closed in satisfaction. "But after you've fucked my sexy cunt sore I'm sure you'll quickly remember the warm, nasty tightness of my asshole again, soon as it's filled up once more with your rectum-pleasing horsecock."
Set nodded, his concentration of the here-and-now stuffing of her sopping wet pussy briefly distracted by the thoughts of going back into her clutching buttocks, pounding it raw... and maybe even spurting out a great load of creamy heated jizz into her hungry bowels...mmm...

Set was quickly brought back down to reality by two things. First, the feeling of the length of his mighty shaft now completely encased within a super tight pussy that was busy soaking him in its honeylike juices. Second, the interruption of Alyxia, clearly torn between exasperation, amusement and sexual hunger.
"Oi! Stop being away with the fairies and fuck my slutty cunt already! You can bugger my pretty butthole later, and fill it with your tasty manmilk ready for this whore Zayi to suck out, but for now you're a foot deep in my horny honeypot, so quit staring into space like a lost sheep and FUCK ME!"
Zayi groaned at the mention of the future task for her, groping one of her massive mammaries and roughly jamming fingers into her own lusting, engorged butthole.

Set grabbed Alyxia's huge stuck out melons, squeezing them and revelling in their softness and juiciness as he used them as his handholds in his thrusts into her foaming snatch.
Alyxia moaned in short bursts, her back bent over slightly and her butt stuck out as Set's turgid cock disappeared and re-appeared between her dripping legs.
"Tell you what." She breathed. "Zayi-Whore, how would you like to have your own slut anus filled up after mine? How do you wanna share ass juices between us?
Zayi nodded excitedly. "Mmm yes pleeaase! I'd love that so much!" The pace of her fingers screwing her own rectum increased in speed and roughness. Wetness flowed down from her pussy to coat her dirtily sodomistic fingers and ringpiece, allowing enough sloppy lubrication to **** two more fingers in, sultrily popping them in past her sticky sphincter with a lewd and debauched look on her makeupped and semen-stained face.

Alyxia licked her velvetine lips as she viewed the nasty display of anal masturbation. "Well Miss High-and-Mighty, bring that big black booty over here, and prepare to have that delicious-looking dark ring rimmed, tongued, sucked on and royally eaten out by the best asskisser around!"
Zayi promptly removed her fingers from her slick rectum with a 'shlllop' sound, stood up and walked in front of Alyxia, bending over with her hands on her knees, her perfectly pendulous cum-dripping breasts swinging beneath her as she happily presented her ass for Alyxia's inspection.
