Manage to find a way to join together

Sophie 3: "Aww c'mon, do you really want that?"

Sophie 1: "As hot as it would be to smother the planet under my gorgeous butt, I wanna keep a functioning society around me so that I'll be able to go to restaurants, buy nice things and go on dates."

Sophie 4: "We could just staff all the restaurants, produce all the nice things, and you could go on dates with us!"

Sophie 1: "Yea... no. Actually maybe sometimes for funsies, but the point is, we need a way to reduce our numbers."

Sophie 4: "You could just kill us."

In saying this, Sophie 4 has wide puppy dog eyes. The other Sophies look at her indignantly. Do the clones get stupider the more there are? Hopefully not, and this one's just an outlier.

Sophie 1: "I'd rather just absorb you back into myself. You know, since we can clone, it's not unfeasible to assume that the reverse is also possible?"

You try to sort of mentally pull back your clones into yourself. In moments, the clones dissipate as if into thin air, and you can feel their entire essence compounding into yourself. Their memories, their thoughts, the sex they just had... The feeling is so overwhelming that you orgasm hard there and then, causing a new clone to appear. You and your clone also each orgasm again, producing two more clones. Now you're back to four.

Sophie 1: "Nghh.... Well that kinda worked."

Sophie 2: "G-good gawd that was a metric fuckload of pleasure!"

Sophie 1: "Yea. I didn't even know I was capable of multiple orgasms, but apparently if you funnel in an orgy's worth into a single person, they sort of compound..."

Sophie 4: "I wonder what would happen if you made like a hundred clones, and we all had constant sex for a day, and then you absorbed all of us at once?"

Sophie 1: "I'm gonna guess that my brain would fry like a snowflake dropped into hot oil. Let's not do that."

Sophie 4: "Oh you're no fun!"
