Fantasies about my friend

So I’m friends with a girl named Bri and I’ve never done anything sexual with a girl, but I want to have sex with her sooo bad. I see her naked all the time when she changes in front of me and she’s even shaved her pussy in front of me before. I’ve seen her pretty clit pretty close up and it makes me so wet. Ive texted her while having sex before, I’ve cum looking at pictures of her before, and I made guy talk about her and I rubbing pussies together while he fingered me and I squirted everywhere while I screamed her name. I can’t hardly take it anymore I need to put my mouth on her hole 😩 anyone know any masturbation tricks that feel like tribbing? I need to pretend it’s Bri rubbing on me
