They're both April now

"Of course," you reply with a grin. "They were both changed, but the real 'template' was Michael's mom. They're both April now."

Mike tears his eyes off of the identical women, glancing at you for a split-second. "Won't that get confusing?"

"We can get something to tell them apart when we need to," you continue. "A couple of collars, maybe, labelled 'one' and 'two...' But I don't want them diverging or anything, so we'll switch the collars around every morning."

"Speaking of divergence," the doctor begins, "I had a couple of ideas that--"

An apologetic voice cuts her off. "Um, sorry, just a sec." One of the Aprils is looking at Mike intently. "That cock looks pretty stiff, baby. Do you need some relief?"

"Oh my God, thank you," the other April pipes up. "I was just about to mention it. Want us to help you, sweetie?"

Mike gives you another glance, tilting his head questioningly.

"Go ahead, man," you tell him. "You enjoy yourself while I touch base with the doc."

"Thanks," he grunts, beckoning his parents closer and pointing to the ground. They leap to either side of him and kneel down, their curvy bodies bouncing with excitement. Two seconds later, both Aprils are licking their son's engorged member, lapping at it until the whole shaft is glistening with spit.

"Anyway, you were saying?"

"Right, um... Divergence. Your lovely ladies are the same for now, because their minds and bodies have been synchronized... But as time goes by, they'll have different experiences and make different memories. If we want them to say the same, we'll need to perform regular check-ups. Just to keep them in sync, you know?"

"Sounds like a plan," you reply, nodding. "I'm sure we'll get a significant discount?" The doctor looks skeptical, so you continue. "My sexual satisfaction is very important, after all... And besides, these check-ups will be a great opportunity for you to make more observations. You're still planning on writing up some kind of article, yeah?"

That gets her on board. "Right, of course! Good thinking. I'm sure I can work something out with management." She pulls out a notepad and scribbles something. "That's about all we need to discuss today, Mr. Doe. April and, um, April are fully recovered and clear to go home. Please enjoy, and if you have any questions, don't hesitate to call me!"

You shake the doctor's hand and she bustles off. The nurse Mike was using gets up off the floor and follows her out, leaving you alone with your friend and his mothers.
