My best friend and older brother

I'm 16 and my best friend goes out with my older brother. She tells me all about them having sex and we laugh but I secretly listen closely to the details and I think about them when I play with myself. One thing she says is my brothers cum tastes good. I get so wet when she tells me and I think about tasting it and how hard he would be. I think about him being inside me instead of her and how I could make him cum deep inside my wet pussy.
