my brother's girlfriend is amazing!!! the day his girlfriend stayed over for the first time, i was masturbating in my room when my erect dick was seen... after that, when my brother wasn't looking, she turned her ass towards me and started appealing that she wanted to fuck! i thought it was lucky at first and fucked her, but her libido kept escalating... having sex with my brother's big-butted girlfriend in secret from my brother!!
