I really need to improve my grades, so I go to my professor to see what I can do about it. I tell him I'm willing to do anything as long as my boyfriend doesn't find out! I convince him by teasing my tits. His cock is huge! After giving him a blowjob he slides it into my pussy from behind. It feels so good inside me. After fucking me on his desk, I ask him to cum on my face. I tell him I should come for extra tutoring more often ;)
