You. Obviously.

You use your powers to slow She-Hulks reactions as she runs. You then deliver a right hook to her jaw and convince her it felt like getting hit by Thor's hammer. She falls to the ground but quickly gets up and backs away from you. "Stronger than you look." She says, rubbing her jaw.
"Well you better be as good at sucking dick as you look." You taunt. She-Hulk charges at you again but this time you trip her up and climb on top of her, convincing her that you're too heavy for her to lift. You deliver a few more punches to her face before Cap separates you. She-Hulk tries one last swing at you but you slow her down enough to move behind her and pull her leotard up at the back, giving her a wedgie and showing off her muscular green ass. You convince her this is the worst pain she's ever experienced and she taps out. "Okay, okay you win!" She shouts in pain. You release her and she turns to face you, pulling her leotard out her ass. "So do you want to go to my room now, or later?" She asks in defeat.
"Oh we're not going anywhere." You say and point to the floor of the ring in front of you.
"What!? Here!? In front of everyone?"
"Yes"
"Fine." She drops to her knees in front of you. You pull your dick out and slap her face with it, you make it feel like getting hit with Thor's other hammer. "Ow! was that necessary?"
"Shut up and get to work." You make the crowd cheer as she grabs your dick and licks the tip. She then wraps her green lips around it and takes it into her mouth. She sucks the tip for a while but you decide a resilient girl like her can take a bit of face fucking. You grab the back of her head and ram your cock down her throat repeatedly. She gags and looks up at you with wide eyes. You can tell this isn't the first time she's done this. You hold her head down with her nose pressed against you and you feel yourself ready to explode.
