The Loser goes down on the Winner

"The loser must go down on the winner" You tell her.
"I'm fine with that. Hope you like eating your greens." She winks and makes her way to the ring. You can't help but stare at her muscular green ass clad in a tight leotard. It is almost at eye-level after all.
As you make your way to the ring, She-Hulk makes sure everyone in the gym gathers round and pulls Steve Rogers in to referee. She starts stretching as you step between the ropes. Cap gathers you both in the the middle. "Okay, standard mixed martial arts rules. Keep it clean people. Go to your corners." You both do. Cap takes a step back and rings the bell on the wall. She-Hulk charges towards you.
