In the end, he inserts it raw! Creampie! My younger sister, who goes to a slutty girls' school and wants to graduate from raw sex, makes a ridiculous request: "I want you to teach me how to put on a condom!" She says, "I want to practice putting on a condom, so I'll get you hard," and starts giving me a handjob! I thought there was no way I'd get an erection from my younger sister, but in an instant, I got a full erection!
