My stepbro the genius fucks me while tutoring

I have been having troubles with my studies so I cut off a deal with my smart stepbrother that he can suck my tits and fuck my pussy if he tutors me. He of course was smart enough not to take my deal! So after a long day of studying the long awaited sex had come. I sucked his dick so much with passion that he really liked it. Him fucking my tight pussy and having him cum all over me was more than enough reward for helping me study.
