Play dirty

You realize that the only way you might be able to get her off you without losing your dignity and tapping out is to play dirty so you reach your right hand towards her and roughly grab one of her boobs, gripping and twisting it as hard as you can in hopes it will make her loosen or even relinquish her grip.

Your sudden, forceful squeeze and twist makes her yelp in a mix of pain and surprise "What the fuck is wrong with you? You are gonna pay for that." She glares at you and swats your hand away.

She gives one extra vicious squeeze with her legs before letting go. You gasp as she releases you and try to roll away but before you can do so, her fist comes crashing down on your stomach, eliciting a pained groan.

She presses her fist harder into your stomach "You think it's okay to just grope me like that?" You grab her wrist and try to pull her fist away from your stomach but she is too strong. She leans in closer to your face, anger evident in her expression.
