Ballbusting Your Stepbrother

You are a teenage girl named Lucy. You have long, strawberry blond hair and a slender figure. You have lived with your stepbrother Alex, who is only a few months older than you, for about a year now, and it's gone pretty well between you. Now that summer has arrived, your parents are going to be on vacation for quite a while. With this comes the opportunity for you to have quite a bit of fun.

You have always known that a boy's weakest point is between his legs. Whenever you were watching a movie with Alex, you would laugh at guys getting hit there. This made him quite uncomfortable, which just made it even better.

Despite this, you haven't actually hit anyone yourself. In elementary school you can recall one of your friends being dared to kick a boy. She came up to him from behind, and snapped with force you would never expect out of a little girl. The boy fell down in pain, and you can't even remember him getting back up.

Part of you really feels bad for guys having such sensitive parts right there between their legs, and all the pain they have to go through. But there's another part of you that is fascinated by it. That second part has come to power today, so you're determined to get your stepbrother sometime soon. But you can't decide how it's going to happen yet.
