[Ichimura] First Time XXX (Otokonoko HEAVEN Vol. 18) [ShotaYuu]

Manga-loving schoolboys Kazuma and Minoru share a weekly serial ritual until the afternoon discovery that one of them has been hiding a sailor uniform and a stash of toys. What starts as shy teasing — "can you use this even when you're a guy?" — melts into breathless first-time exploration, with buzzing toys, eager hands, and a flustered boy learning exactly how good it feels while his friend whispers about how incredibly hot his insides are. By the final embrace the games fall away entirely, as "I've been thinking about doing this with you all day long" turns a curious experiment into something far more honest.
