After their onsen soak, the men retreat to a private tatami room. The handjob continues, the giver's slick, soapy hand gliding up and down the other's shaft. The recipient's moans fill the room, his body tensing as he approaches climax. With a final, firm stroke, he releases, his cum shooting onto the floor, a stark contrast to the pristine room. The men clean up, their bodies still glistening from the hot spring, their eyes promising more to come.
