Little Brother was NOT expecting Big Sister to come home in the middle of the night to teach him the lesson of a lifetime. "You don't know why you're pitching tent? It's because your penis is supposed to go inside a pussy." Lots of dirty talk when big sister educates you on how to kiss and fuck. There's no pulling out today. "I have sex with all my brothers, and I've been waiting for you. Put a baby inside me. Spray your milk!"
