Bathroom. It's a great time that every Japanese person loves, as it promises the ultimate in relaxation. A bathtub with flickering steam and a moderate temperature. A man and a woman in a close relationship bathe naked, and the heat arouses sexual desire. The glossy, moist skin overlaps, and the rubbing of the wet cock and private parts enjoys a pleasure that can't be experienced on the bed. 4 hours of bath time filled with mixed bathing sex that will make you forget yourself and go crazy.
