Everyone stepped to the side of the room, allowing Reg to greet the pony who was making her way down the stairs. When she emerged the entire group recognised her as Rarity, and shocked murmurs went through the crowd at how Reg was able to persuade one of the most high class ponies in all of Equestria to become what was essentially a prostitute for the group.
"Oh my, so these are the 'clients' you were referring to last night." Rarity said as she walked towards Reg.
"Indeed they are, my dear." Reg said as he noticed the fine dress Rarity was wearing."That's a nice outfit you got there. You know, if you get a bit hot you could always just strip off." Reg said, leaning in towards her and putting emphasis on certain words as to create no uncertainty as to his true in.
"Wait, are you trying to- You are!" Rarity gasped as she realised what she was here for.
"Yes. Now hurry up and get that thing off." Reg said, seeming awfully blunt, given the circumstances.
"Never! How can you honestly expect me to just parade about naked for anyone who asks? I mean really, who on earth would have the nerve to even suggest such an idea?" The unicorn began and intended to continue for some time, most likely. Reg Sighed, not wishing to be subjected to a morality lecture.
"Listen Rarity. You may be offended by the idea now, but if you just give the issue some thought I know you'll not regret what we're asking of you." He said to her in the most charismatic and sensual voice he could muster. He stared at her intently, as if he was looking into her soul. Rarity stared back, almost bewitched, before silently admitting defeat and removing her dress. Reg rubbed his hands together in anticipation. He had experienced ponysex before, but only now could his old feller get in on the action.
"Lads, avert your eyes." He said before stripping himself of his clothes. He was finished in good time to watch Rarity undress, and was relishing the chance to prepare himself for the task ahead. However, just as he felt his member reach its full extension, he began to hear the unmistakable sound of footsteps. Except they weren't, they were what would be more accurately discribed as hoofsteps.

Reg hadn't prepared for this, all he could do was stand there and take what was coming to him. He listened to each step Twilight took down the stairs in time with his rapidly beating heart until. Twilight reached the bottom of the stairs after what seemed like an eternity. At first, she didn't know what to make of the situation. She could register nothing but complete shock at seeing one of her best friends about to have sex with some unknown species. But the more she thought about it, the more the situation slowly began to turn her on. Awkwardly, she approached Rarity slowly before addressing Reg.
"You don't mind, do you?" She said, blushing slightly. Reg thought to object, before it dawned on him what this situation entailed.
"No, go right ahead." He said, his awkwardness now being faked in an effort to disguise his extreme arousal at the thought that had just hit him. He stepped back slowly into the group, putting his trousers back on as he did so, while Twilight and Rarity walked towards each other. Slowly, the two unicorns kissed. They were nervous at first. But now that they had the taste of each other, nothing in the world would have stopped them. Before long, they'd adopted a 69 position. The group of humans stared at them, each of them not surprised to have a stiffy. This was like everything they'd ever wanted fully realised. Towards the back of the group, Flutterfuckershy was tempted to go off into the corner and have a wank, but then they two ponies did something not eve he'd ever expected.

Twilight and Rarity began to change positions slightly. Twilight rolled over and shoved her horn in Rarity's vagina, while Rarity did the same to Twilight. The two took a moment to enjoy the erotic sensations that this act brought on, before Twilight turned her head to Reg.
"You want in on this?" She asked while trying to keep back moans of pleasure. Reg approached them enthusiastically, undressing for the second time, when he stopped. He turned back around to the rest of the group, trousers halfway down his legs, and asked the, a question.
"Any o' you lads fancy a go too? This looks like a bit of a two man job, if you know what I mean." He said. Upon hearing these words, Flutterfuckershy shot to the front of the group as if someone'd shot at his heels.
"Why didn't you say so before? Let's do this!" He shouted. Reg nodded at him, and the two went to work. Reg lay on the bottom with Fuckershy on the top. Almost perfectly in sync, they slid their cocks into the two ponies arseholes, surprised at how easily accessible they were. The four of them went at it like mad, moaning and shouting as if they had something to prove. It felt good to them, but confusion went through the crowd.
"The fuck am I looking at?" One human whispered.
"I dunno. Looks to me like some kind of double decker sex sandwich or something." Replied a second. They didn't have to question the spectacle for much longer though, as the four of them all came one after the other. Panting heavily, they rolled off each other and the two humans began to put their clothed back on.
"Well, that was truly something." Rarity remarked as she too put her dress back on.
"I agree, I've haven't felt that good in forever." Twilight said as she stood up."Thank you for that Mister, um," She said as she realised she didn't know the name sod either of the two creatures who had just brought her to climax.
"Reg." Reg said as he mimed tipping a hat in her direction.
"And Gerald." Flutterfuckershy, or Gerald as he was now known, said.
"Gerald?!" Reg blurted out, trying not to laugh
"Shut it." Gerald said to him.
"Okay then, Reg and Gerald, would you like to stay for a while?" Twilight asked the two of them.
"Why that would be lovely, yes." Reg replied calmly. But then a voice broke out from the crowd of humans.
"But mate, what about uploadi-" it began before it was cut off.
"Shut it!" Reg shouted before turning his head back towards Twilight."Terribly sorry about him, off his meds, you see."
"But seriously, what are we gonna do with the foota-" The voice said before being cut off again.
"Will you shut your fucking face? Erm, actually we'd best be going." Reg said as he ushered the humans back down the tunnel.
"Wait!" Twilight shouted after them."What are you? And why do you have a tunnel leading to my basement?"
"Long story!" Reg shouted as he and all the others disappeared down them tunnel. And that was all he said.
