Charge at her!

Emily looked pretty mad and you wasn't about to wait until she attacks. You rushed at her and take her by surprise, throwing a heavy punch in her soft belly. She doubled over in pain, coughing and falling on her knees. You instantly regretted hurting such a beautiful girl and take a moment to appreciate her nice butt as stands on her knees. You feel a boner appeared in your pants.

"I'm sorry, Emily, but you attacked me first," you told the girl.

She growls at you in rage and climbs back at her feet, still holding her belly.
