Does this guy really think he can treat you this way? He will regret it.

“Eric is not my boyfriend,” you mumble under the hand of the shop clerk.

The shop clerk looks surprised and weakens his grip a little. Terrible mistake. Much faster than he can react you break free, turn around and smash your knee powerful against his balls. For a moment you think his eyes pop out of his head when the asshole quietly gasping goes to his knees. There he kneels. You can’t believe how pathetic this guy is. He tried to take advantage of you but after a single knee hit to his babymakers he can’t move anymore.

You consider your options for a second. You can now either scream and get this wanker arrested or you punish him in your own ways. If you choose the first option, your father will likely get him executed in prison and maybe Eric gets in trouble too. But if you punish him on your own you would do vigilantism and maybe he tries this shit again soon. But it would be more fun.
