My little sister teases me crazy all the time. She caught me jacking off in my room last month, and now she teases me. Not about me jacking off, but she makes me hard and laughs.

She is 16 and built. When nobody is looking she giggles her tits so I can see. Lifts her top. Or sometimes she'll run from the bathroom to her room naked if she knows I am in the hall.

She does this to get me hard, because she knows I JO a lot. She is not interested in anything sexual with me, believe me I have tried. She doesn't watch or listen. She just teases me crazy and I end up in my room jacking off.
