...

After a long, grueling day of training, you had somehow managed to convince Phainon to join you in the private baths for a much-needed soak. He was visibly hesitant the entire walk there, his usual stoic expression cracking with faint embarrassment, but he eventually followed you into the changing rooms.

You emerge first, wrapped comfortably in a long, modest robe that covers everything important. A few moments later, Phainon steps out behind you. His robe is much shorter than yours, barely reaching mid-thigh, leaving his powerful legs and, more noticeably, the thick, crinkly white water diaper completely exposed. The padded garment is snug around his waist, the tapes secure and the faint plastic sheen visible under the hem of the short robe. Phainon freezes for a second, his cheeks flushing a deep red as he notices your gaze. He quickly tugs at the hem of the robe, trying to pull it lower.

"...This is ridiculous" He mutters, voice low and gruff with embarrassment. "The staff won't let me in here anymore unless I'm... wearing one of these. Not after what happened last time..." He avoids your eyes, shifting uncomfortably as the diaper crinkles with the movement.
