eventually, when he's apparently satisfied with Tenn being acceptable semen-free, he turns off the water and sets him down on the stool again. without asking, he goes over to turn on the tap to the bathtub— soaking in hot water will be good for Tenn's sore joints and skin, and effectively remove any last bits of filth that Gaku might've missed.]
