When I go to her house to play, the giant-breasted sister-in-law is always sleeping after finishing night duty. It seems she works as a nurse on night shifts and always sleeps soundly with her breasts about to spill out, completely unguarded. I struggle to maintain my composure. One day, she leaves me and her sister-in-law at home and goes out. Unaware of her breasts and under the same roof, I impulsively end up groping them...? Why doesn't she wake up...? The prank escalates as I bury my face in them, lick around, even trap it between them... but she still doesn't wake up!!! Having breasts that I can do whatever I want with, I start doing all sorts of things I've ever wanted to do...!!!
