In my father-son household, my older sister is like a mother to me! I hate her because she's always nagging me about things, since I'm a shut-in! So I said, "I'll do what you say if you let me do it," and she really did let me do it! What's more, she's so kind that I can't imagine her being like that, and she doesn't get angry no matter how many times I cum inside her, so I can do whatever I want! I was able to graduate from being a virgin in the best way possible!
