If school girl Beth Bell doesn't do something drastic, she's going to fail Biology. Her teacher Ms. Shiri is nice enough to invite her over for after school tutoring. Ms. Shiri sees that Beth isn't really the type of girl that's interested in reading books, in an effort to grab her attention and help her, she decides to teach her with something a little more hands on. Beth Bell, puzzled by what DNA is, decides that Ms. Shiris idea to extract some DNA (from her huge cock) is a good idea to learn. Beth fondles Shiri, then the two take turns sucking each other off. Shiri slaps Beth's ass with a ruler and then fucks Beth bareback in her tight little ass long and hard! Shiri fucks Beth in multiple positions and when she's finished teaching her a lesson, she blows a HUGE load all over Beth's cute little school girl face!
