I live with my extremely lazy sister, and I do almost all the housework! But I don't complain! Why? Because in exchange for doing chores, I get to grope her huge breasts for a whole minute! At first, she was unresponsive, but as I got better at it, she started to feel it! She can't hold back her urges anymore, and we repeatedly have orgasms from breast groping and internal ejaculation. She's completely transformed into a sex-crazed slut! It's truly an enticing deal!
