I want to fuck my friend

We know each other for half of our lives. We're best friends. And I really, really wanna fuck her.

All the flirtations rot my brain. New dynamics between us, but it's all talk and no action. It's like listening to someone describe how the cake tastes and not being able to taste it. So we flirt, talk about what we like, talk about sex, and I think about her, her beautiful body, I dream about her. I know when she masturbates. I come thinking about her touching herself. I fantasise about my mouth on her neck, about my tongue between her legs. About her fingers inside of me and her other hand on my lower stomach. I want to hear her moan. Explore kinks together. Be the body she can use for her sadistic pleasure.

Can't be all my fault. She's been as bad as me the last couple of weeks. It's thrilling. It's frustrating. She means the world to me. I want to touch her all the time.

It's bad and I shouldn't do it cos she has a girlfriend.
