A new discovery that you can see as much of their underwear as you like while they're in the kotatsu!

When I looked inside the kotatsu, what do you know?Her panties are completely visible! When she plays with her crotch with her fingers, the heat from the kotatsu quickly makes her pussy all sweaty and wet. She fucks him raw inside the kotatsu, which is full of the smell of her sweaty pussy.
