[C Hange (Hangeshō)] Bodyswapped School Trip

A class trip to a hot-spring inn goes sideways when the boys fish a strange mirror out of the bath and one flash of light later, Komi and Koga are stuck wearing each other's bodies. While the girls' room erupts into giggling, clothes-stealing chaos before lights-out, the two swap victims quietly slip away into the night, where idle curiosity about what the other half feels like turns into a very hands-on experiment with borrowed anatomy. Nervous consent, perverted discoveries, and one extracurricular activity that was definitely not on the itinerary.
