My sister, who is usually mean to me, treats me like a virgin, teasing and making fun of me. Although she is generally considered cute (beautiful) by the public, she is a sadistic sister who vents her stress by bullying her younger brother... Today, on the way back from school (work), she must have been under a lot of stress, as she bombarded me with obscene language that she usually wouldn't say out loud, and while she smirked, she toyed with my dick and quickly squeezed out my cum...
