Rarity, that is, the one who had brought you here, gently encircled your glans in magic and pointed it straight upright while her magic did the work of sliding up and down your spire. Another bit of magic broke away from the first and centered around your testicles, squeezing and massaging them like they were a block of putty. This unbeatable combination of sensations caused you to shudder in delight and your tongue to hang freely out of your mouth,

Your hands clawed at the sheets for purchase as you arched your back. Rarity seemed rather pleased with herself at your reaction and shuddered a bit herself as she tweaked at her own clit with her magic. Heavy blushes adorned the snouts of every mare present. Each of them was pleasuring themselves in their own way.

"They're not just my clones, darling," Rarity revealed between moaning breaths. "Believe it or not, they're all versions of myself from completely different worlds, each one of them from a different stage in my life. I met them while experimenting with dimension-hopping during my magical studies with Twilight. Aren't they just darling? This pocket dimension connects to all of their home dimensions."

"It's true. It was such a surprise meeting my younger self when she slipped into my boutique, but not an unpleasant one,"
fawned the older version of Rarity, whom you shall henceforth refer to as Milfity, "We traded dress ideas for a little while, and when she asked me if I could link her home to mine so that she could visit more easily, I gladly accepted. What a good thing I did, since she brought this hot piece of meat into my boutique."

Rarity smirked and then drew her slightly younger teen version close to her, wrapping a foreleg around her shoulder. "Yes, and this one was starting to go into the sewing business when I found her, and with my help and expertise was able to run and manage a business all on her own at a young age, even younger than I was when I first started. She's going to go far in life, I guarantee it."
Rariteen blushed and scraped her hoof against the bed as if she was getting bragged on by her own mother, but said nothing to counter and deny it.

A squeaky voice came from beside her, not quite the MidAtlantic flavor of her older counterparts but somewhere close to that of Sweetie Belle. "Hey, what about me?"

"Oh, right." Rarity stepped away from the teen and fondly patted the filly between the ears. Filly Rarity closed her eyes and received the petting with pleasure while let her ears droop to the sides. "This one right here is a very special filly. A magical prodigy of unmatched potential and the next in line to receive the Element of Magic in her own universe. Right now she's enrolled at Princess Celestia's school of magic, but I'm sure they won't mind if I 'borrow' her for a little while. As you can tell, she's very eager to have her first encounter with a real stallion so I didn't want to let her down."

... Wow. You of course knew that there was a myriad of other possible universes out there with different versions of the mane 6, but to meet three of them here in the flesh at the same time was an experience on another level. The magical kneading on your nutsack ceased but Rarity's magic still held your glans upright in her magic.

Rarity flashed you a lascivious grin and heavily batted her eyelashes. Now was the time for the main event. "Now that we've all had the chance to introduce ourselves, why don't you choose which one of us will get to go first?"
