My lazy sister who lives with me is always slacking off on her housework. So I added a rule that I can rub her breasts for 3 minutes in exchange for doing the housework! At first, she didn't react, but as I gradually got better at rubbing her breasts, she started to feel something... She came over and over again on her breasts, wanting more than 3 minutes of pleasure! Then she suddenly became so lewd that she wanted my dick and asked for a creampie...!?
