The narrator tells us that he's going to have sex with one of his classmates, who is hiding under the cover of darkness. He's worried that they'll find out about it, and he wants to do whatever he can to make it happen. He wants to make sure that the other students don't see him having sex with his friend. He tells his friend to rub the ground around him with a warm cloth, and if he doesn't like the feeling, he'll stop. He also tells the friend to squeeze him a little, and the two of them go off to meet up with some other students.
