Pony ride

You start crawling around the mat, carrying your Aunt on your back, giving her the most demoralizing pony-ride of all time. You struggle under Rosies weight, she's heavier than you thought, and can only make it halfway across the mat before you have to try to regain your composure.

"Pathetic!" Rosie yells before smashing her gloves against the sides of your head again. The force from her blow causes you to fall forward, pinning your cock between your stomach and the mat.

You try to lift yourself back up, but Rosie has other plans. You're barely able to put your hands on the mat when your aunts still-gloved hands start striking you repeatedly on the back of the head.

The strange combination of adrenaline and humiliation is overwhelming you, precum starts leaking from your dick as you squirm under Rosie. The sensation of your dick rubbing between the mat and your body feels... Amazing! You soon start moaning between grunts of pain as your Aunt pummels you.
