Amy cumsplains.

“So this time your body may go through some changes it didn’t before,” she begins as if explaining the birds and the bees. “Remember how I said most of your changes wouldn’t be permanent unless you kept getting knocked up? Well, good news! After this much nanotech is firehosed up your fat ass, I think it’s more likely that you *will* retain your more fertile additions. Bra shopping is definately in your future, and thongs for your lower assets, unless you like feeling bunched up panties giving you a wedgie all day.”

“Amy, my cum bubble belly isn’t resting on the floor yet. The pressure on my hole is getting painful! *That’s* what I want to know!”

“Oh, that! It can’t hold up forever. Not with these puppies stuffing it,” Amy pats her balls on each side. “Just be patient! Remember that your body is adapting to long-term changes of being repeatedly inseminated. It’s not just your chest and hips, but also the elasticity of your skin. Look, see? It’s coming down.”

You watch the volume slowly wobble and sag between your legs until it rests on the ground. Your robot bounces you up and down on her crotch as your breasts bounce as they slowly increase in size even without milk production.

“Look at these boobies! You are so cute!” Amy squeals. “Those hips and thighs, too! Rawr! We are going to make you a sexy outfit for between pregnancies!”

“Oh really? I-I don’t think that’s necessary,” you brush off the thought.

“I insist! I’ll make you something custom that will fit perfectly! I’m the one ruining *your* body, after all! I can make it extremely erotic and lewd, too!” She slaps and then manhandles your big butt to make the point.”
