I saw my boyfriend's stepsister naked

The other time at my boyfriend's house, we were watching movies as usual, everything was going very well and we were very hungry and we decided to order food through Uber Eats.

While we were eating, her stepsister arrived from work and went straight to her room. We felt bad and decided to invite her to eat, so I went up to tell her there was food ready.

But when she went up her door was a little open so without knocking I opened the door for her to come down to eat and when I opened it I saw her completely naked because she was about to take a bath.

I really ran out and I don't remember if she saw me. When I went down I felt very nervous and my heart was beating a lot, with shame and a little intrigue.

That day I didn't say anything, but all week I kept thinking right at that moment, remembering her body, so perfect and very well formed. It makes me so excited to think about it, and I feel wet, that I decide to touch myself until I reach ecstasy, but I don't know what else to do.

I think about a threesome at night and I start to feel wet and eager for both of them. Oh god
