Miss Cate has caught this student kissing other boys. So, it is important he gets some proper sex education. So that when it is time to be bummed by other boys, either for fun - or to get ahead in a career - he will be ready. Bending him over the desk, she loosens his arsehole with her gloved hands - before she is ready to give him the sex education he needs. A big, hard, fucking, over the Head Mistress' desk. He moans as his tight arse is stretched by the Head Mistress' arse; his anal virginity taken. He doesn't need to just kiss the boys anymore; he's been upgraded.
