I was admitted to a university in Tokyo, so I moved in with my sister. She is an extremely lazy person. Although I had divided the housework before living together, in the end I was the one who had to do it all. Too tired of doing free housework for her, I decided to make conditions with her. If you give me a breast massage within three minutes, I will do the housework for you. At first, she seemed reluctant and unwilling, but laziness conquered shame, so she agreed. And since then, with her laziness, I have been constantly squeezing her beautiful round and full breasts. My breast squeezing technique is also extremely skillful, making her extremely hot! But as soon as she was close to the top, the time ran out, making her feel extremely uncomfortable. And then, when she couldn't control her heat, she took the initiative to come to me, asking me to do housework so that I could continue to squeeze her breasts. But when the three minutes were up, she didn't let me stop but continued to make me squeeze her breasts. Not only that, but she also sucked my cock for me, inserted my cock into her pussy, and even let me fill her uterus with sperm! And from then on, my sister decided not to do housework anymore, forced me to do it for her, in return I could continue to squeeze her breasts at any time...
