In the cramped, humid shower, Mirio and Tamaki's initial banter turns into a heated exchange. Tamaki, driven by pent-up desire, grabs Mirio's cock, stroking it vigorously. Mirio, taken aback but eager, returns the favor, handling Tamaki's throbbing member with expertise. The sound of running water and their ragged breaths fill the small space as they push each other's limits, their bodies pressed together in a passionate dance, ultimately leading to a satisfying release.
