My slovenly sister who lives with me is constantly slacking off with household chores. So, I added a rule that instead of me doing the chores, she would let me massage her breasts for three minutes! At first, my sister was unresponsive, but as I gradually got better at it, she started to feel it... Demanding more than three minutes of pleasure, she repeatedly reached her peak with breast stimulation! Then, she became so lewd that she started craving my penis and begging for creampie...!?
