Miss Lyall is teaching her class about sex education but they are struggling with the biological details so she calls Josh up to demonstrate. To the students amazement she strips him naked and starts wanking and sucking his cock. She then gets each of the girls to have a wank and suck of their own. Finally Miss Lyall removes her thong and straddles Josh's cock, riding him to an orgasm before bending over and getting him to fuck her doggy style. As he gets close he pulls out and explodes all over her ass as his female classmates watch in excitement!
