Pistachio and Pommel

Coco simply took a deep breath, swallowed her nervousness, buried her unfair complaints and said "Yes Miss Rarity" before stepping forward and slipping into the strap-on and securing it around her waist. Pistachio was surprised that Coco had still yet to realize that he was actually a boy, but at this point, he felt more like a girl than a boy anyway.

Rarity raised the riding crop and gently patted the tip against Pistachio's left ass cheek "Come on then Coco" she said "Come here and fuck her ass".

Coco raised an eyebrow in confusion at Rarity and asked "Not her pussy?"

Rarity shook her head and said "No, no pussy action. I don't want you to fuck it, touch it or even see it..." Rarity gave a little smirk before saying "In fact... pretend that her pussy doesn't even exist". The exquisite irony was completely lost on Coco, still under the delusion that Pistachio, with his extremely female physique and slutty outfit, was actually a girl.

Coco popped open the bottle of lube and spread a decent helping all over the strap-on before putting it to one side, she looked at the butt in front of her she had been tasked to fuck, this girl had such a cute little booty, she was the pinnacle of of both cuteness and beauty. Coco took hold of the waistband of Pistachio's panties and pulled them down a little, though not enough for her to spot the very obviously caged up cock and balls between his legs, Coco was more focused on the clear silicon ring sticking out of his hole. She looked to Rarity who simply nodded as if to say to "go ahead".

Well, at least the hole would be slightly easier to penetrate if it had already been lubed and stretched. Coco hooked two fingers around the ring then, making sure she had a decent grip on it, began to pull in an attempt to tug the anal beads out of Pistachio's ass, though that proved to be tougher than she initially thought due to the tightness of Pistachio's pucker and the size of the beads themselves. Coco had to put a little more strength into her pulling before the first bead finally popped out despite the resistance of Pistachio's asshole desperately trying to keep it inside him, while Pistachio let out a barely audible moan Coco was just surprised at the size of the bead that was inside him, bead was hardly the correct word considering it was the size of a tennis ball.

Coco continued to pull and another bead fell out, the same size as the first, then a third one just the same as the other two. The final part of the anal beads was the only one that a had a different shape, a cone about the size of an ice cream cone was what finally left Pistachio's ass, making him feel empty, though that feeling wouldn't last long. Coco put the anal beads to one side and positioned herself right behind Pistachio, placing both hands on his curvy fem-boy hips, Pistachio's breath hitched as he felt Coco's hands gripping onto him from behind as anticipation and want filled his soul, she brought the tip of the strap-on to his twitching asshole and prepared to push inside. As Coco predicted, the initial penetration was somewhat easy considering the ridiculously sized anal beads that had been in this girls ass, plus the fact that Rarity had made it pretty clear that her secondary bitch was a real anal whore.

Once the head was in, Coco felt confident she could pretty much plunge the whole thing in without causing too much discomfort, before doing so however she turned to Rarity and said "What's her name?"

Rarity struggled to come up with a suitable female name in her head and went "Oh... her name isn't important, you can just call her bitch".

Coco shrugged and said "OK, get ready for this cock bitch" then began to slide the strap-on up Pistachio's ass until her hips were pressed firmly against his buttocks. Pistachio moaned as Coco pulled out and then thrust back in, experimenting with her movement, Coco had never used a strap-on before so she didn't have much experience in wielding a cock, let alone using the hip muscles required for a pleasurable fuck session. As the strap-on glided across Pistachio's prostate, he could feel his cock straining against its cage, his body desperately trying to force blood into it and make it erect, but it was simply unable to do so. Coco kept up her slow but firm thrusting pattern, leaving a few seconds between each one and making sure that without every backwards movement she left in nothing but the tip and that with every forwards movement she had her hips pressed up as hard as possible against Pistachio's butt to ensure the strap-on was as far in as it could go.

Coco was also similarly disappointed to find that while she could feel the vibrator shifting around in her vagina with each movement, the sensual pace she had set for herself indicated that even the most rigorous fucking wouldn't be able to provide any kind of enhanced stimulation to her pussy, she was stuck riding the knifes edge between orgasm and denial. Rarity was the only one who was able to fully enjoy the act from a viewing standpoint, though at the moment Coco's gentle yet strong approach wasn't quite hitting the mark in terms of the kind of pounding she wanted to see and enjoy, looks like Coco would need a little persuading if Rarity was going to be able to satisfy herself enough to cum just from watching and she knew Pistachio would need something a little bit more intense if he was going to cum as well. Rarity stood up and said "Coco darling, I appreciate that your very new to being the "boy" in the situation, but do stop treating our lovely young lady guest here like she is a delicate little flower and give her a decent fucking will you? Try to remember that while it's important that you enjoy yourself in this new, exciting, kinky and extremely sexual activity, you are doing this for her pleasure and mine, so fuck her like you mean it. Fuck her like you have two fat heavy nuts filled to the brim with pints of thick heavy load that you desperately need to release inside a sexy little butt, OK?"

Coco nodded and let out a breath she didn't realize she was holding as a single drop of sweat rolled down her forehead, she wasn't sure why but she was just incredibly trepidatious about the entire affair, which is why despite Rarity's very clear instruction to start fucking with as much force as she could muster, Coco sped up by a fraction, like a car that had decided to go from 29 mph to 30 mph. Granted she was now in the flow of a nice rhythmic pumping in Pistachio's ass, which he was very comfortably enjoying if his girlish groans were any indication, but it wasn't anywhere near the kind of desk shaking hips-clapping-ass sex that Rarity was looking for. "Coco dear, perhaps I didn't quite make myself clear, FUCK HER" she said in as stern a voice as she could, Coco gulped and took hold of Pistachio's wrists for better leverage and start going a little harder, willing her hips to kick it up a gear and go into full fuck mode.

Pistachio's grunting got louder and more frequent, Coco's waist was meeting his ass with a satisfying but still relatively small and quiet clap on each thrust, but this still wasn't good enough. This was starting to really piss Rarity off "FUCK HER HARDER" she yelled, Coco scrunched up her eyes and leaned forward to grip Pistachio's shoulders, again trying to comply with Rarity's demands. The clapping of flesh on flesh became louder, which was wonderful, but the desk was still very much a stationary object, this wouldn't do at all. "HARDER!" Rarity shouted in her ear and swung the riding crop down fast and hard, striking Coco on her right ass cheek.
