Jennifer Walters -AKA: She-Hulk- is more than a lawyer or a heroine. She's a pretty strong lady with a very strong tights, always ready to crush the evildoers, whether it may be in the court, in the streets, or in the bedroom.
Maybe this guy has a really big tool, but little he knew about Jenn's strong inner walls, capable of crushing watermelons into juice... An that's exactly what happened.
She hulk crushes this bragging boy, to put him in his place, and show him that she goes big with muscles, justice, and dick-crushing skills
