You watch as her body plumps up a bit, her breasts quickly fill to FF cups as she feels them up in the shower. Her waist expands to make way for an exaggerated bubble butt that she goes to squeeze, her hands sink into her softer flesh, leaving your dick harder than diamond. Her hair flows down to her waist and billows outward while as her skin tans slightly and softens up further. Her lips plump up a bit as she bites her lip. She teases her pussy, feeling the lips fatten as she spreads them out. She squeaks a little as her pussy clenches around her fingers, and you watch all this happen while stroking yourself. She turns the water off and smirks at you, knowing she gave you a bit of a show. With the extra weight, you think she would be a bit uncomfortable, but her movements are graceful as she steps out of the shower. She flutters her eyes and gives you a kiss as she reaches for a towel.
“So how long are you gonna stand there staring at me you silly perv?”
She snaps you out of your stupor as you realize, the shampoo turned your girlfriend into the most voluptuous babe you’ve ever seen, even better than the women you fapped to in the past. You contemplate whether you want to cuddle her, just flat out fuck her right then and there, or try some kinky foreplay with her new body.
