You told the Tomboy Milf you wanted to explore her ass more. In response she gives you an unsprusing eyeroll and grabs you forcefully, it was a bit painful of a grab but you did end up tucked between her Buttcheeks as she lays down on her couch.

She was already butt naked when you were shoved in, so you feel every part of her skin, her nasty sweaty remains, her grimy unwashed asshole, the smooth silky shaved bums. 

She took out her phone and begins browsing, all the while letting you do as you said, crawling around her ass. From jumping about to sky diving, fooling around like some bouncy castle. Her plump blubbery butt was nice to walk and press yourself in.

However you didn't expect...
