I Hate Myself For This. Family Fantasy.

Right now, I’m on vacation with my family in a house in Maine. Me and my cousin, who is around my age, are sleeping in the same room. I, of course, being a horny teenager, am finding it difficult to not have certain thoughts. I have this stup!d idea that if she walks in on me naked, something will just happen, so I’ve been leaving the bathroom unlocked. Her bathing suit was hung up to dry in the shower and I’m ashamed to say that I held it and put it up to my face- the top and bottom- while masturbating.
