I’m 16 and my older sister is 17. This evening, I saw her naked but she doesn’t know I saw her. She was walking between her bedroom and the bathroom (while talking on her phone) before taking a shower and she had no idea I got home early from practice.

My mom was working in her office and dad wasn’t home yet.

Emma is one of the hot girls at school (all my friends want her attention, even for a moment), so I’m all confused inside. I’ll admit I got an erection and was turned on as she is only the third girl I’ve seen naked but the first one who didn’t know I saw her. The voyeuristic element is what I keep thinking about. Well, that and her b****.

There’s no way I’m telling her I saw her… at least, well, I don’t know. I’ll admit it seems like a good card to keep in my back pocket for sometime in the future. I’m already trying to figure out how to see her naked or t****** or whatever again.

At the very least, I can see her in one of her bikinis often enough in our pool and when she has her friends over. The trick will be hiding my interest. That wasn’t really an issue in the past, but now it will be.

I’d love to have her catch me naked.
