[MASM-030] A story about how an adult me was played to submit to my damn cheeky bratty niece, Rina Masako (Censored)

I decided to take care of my niece at my house for a week. Even though I made her dinner, she said, "I don't want to eat it! I'll order takeout, so lend me your credit card!" She's a really cheeky brat. I thought I'd show her what would happen if she told an adult what to do, but instead she pushed me down and made me cum inside her in the cowgirl position! "If daddy finds out, he'll kill me lol" I couldn't resist this girl anymore... It was the beginning of a hellish life of having my sperm sucked out of me.
