[Today is the day I had sex with my girlfriend. Her pussy suddenly got loose] A kind-looking black man moved in next door. He had a cheerful demeanor and I really liked him. Apparently, he came to borrow the bath because the gas was out, and we got into a fight over it. But since that day, she's become cheerful and has even started buying new underwear. I got home earlier than usual today. I heard a woman's moans echoing down the hallway, so I peeked into her room. She was on top of the black man, shaking her hips and moaning, saying, "Make it bigger."
