You are going to leave her like this.

"You are going to stay here for a while as punishment. If I need these milky monsters drained, I'll do it myself." You grab a fat nipple and suck on it for effect. The pressure of the milk is more than you expect and you need to gulp it down. You crawl off of Kako as you drain your right breast and increase your belt size as a result.
"How long? My dick is already itching for attention!" You roll her so she is leaning upright against the couch. You wanted to make sure she watches as you run your hands over your curves from top to bottom: lopsided breasts (the one you are sucking still bigger than when you started sucking, while the other has expanded by at least a couple of gallons more and growing) hanging to either side of your distended belly, (mostly filled with Kako's cum pumped up your ass but now filling with your own milk from the top) flaring hips wider than the sag from the belly above, extremely large bubble butt, (firm enough to hold its shape without sagging, but still pillowy soft to cushion any crotch slamming against it and sway when you walk) large muscular shapely thighs...then you repeat a few times...sometimes from the front, sometimes from one side or another, sometimes from the back where she can see the curves of your breasts hanging to either side as you trace their shapes with your hands. When you can't feel your left breast stretching uncomfortably anymore, you let the right nipple fall from your mouth.
