If you have an ass like that, you might as well use it.

Dari has always noticed Ricarda, soon to be Ricci, has a fat ass. Before Mistress Harley changed her life for the better it was just a fact, but now, it is a wonderful thing. The ass is almost perfect, only way it could be better is to be a bit bigger, a bit fatter, and her new dick is making that happen. But the physical changes are not all, she will make it so Ricci will have the most sensitive ass, and love when people touch it, fuck it, spank it, do anything to it. Will make Ricci and Babsy a perfect fit considering Babsy's ass obsession.

For now though, she gets to fuck this prime piece of ass, after she is done plowing her pussy of course, wants to make the changes stronger before she takes Ricci's ass. Ricci's mind is currently lost to pleasure, Dari is close behind as she thrusts into Ricci's pussy. She then starts caressing Ricci's ass causing moans from the strokes and yelps of pleasure from the occasional spanking. After quite some time, and many orgasms for Ricci, Dari finally explodes into her pussy, making the ass fatter, tits bigger, and mind more corrupted. Dari pulls out and Ricci surprises her by standing up and picking Dari up.

"Let's move this to the bedroom sweetie, I am supposed to be servicing you, and I want you to be comfortable." Dari is speechless as Ricci carries her into the bedroom and lays her on the bed before straddling her.

"I couldn't help but notice all the attention you paid to my ass, so I figure you want a piece of it Dari." With that Ricci turns around and slides Dari's cock into her ass and starts riding her reverse cowgirl, this gives Dari a mesmerizing view of a phenomenal ass bouncing up and down on her cock. At first Dari just stares at it, admiring it as it bounces, letting out moans, enjoying having Ricci bouncing on her cock. Ricci moans too and leans forward.

"Touch it. Spank it. I know you want to Dari."
