You make her cum

You sit up, with your Aunts tit still in your mouth, and put your hands on her shoulders. She pushes back against you, but you manage to push her on her back and spread her legs.

You thrust your dick repeatedly in her wet pussy and pin her arms down, but she keeps grinding on your shaft all the same.

Rosie starts moaning as her face shows the pleasure she's getting from your big cock. The back of her head falls against the mat as she cums all over herself.

You pull out and roll her on her fat stomach, before climbing on top of her and reenter her cunt, this time from behind.
