I live with my super lazy sister, but I do almost everything around the house! But I have no complaints! Why? Because in exchange for doing housework, I get to massage my big-breasted sister's breasts as much as I want for one minute! At first, my sister didn't react, but as I get better and better at massaging her, she starts to feel something! Gradually, I can't contain my arousal, and she turns into a dirty slut, asking for breast massages and dicks, repeatedly cumming on her breasts and cumming inside her! It's a truly fascinating deal!
