[Pero (Mesotane)] Loli x Shota unravelling {Chin²}

When Tomo-kun comes to stay over at his friend Nao's house, the last thing he expects is Nao's little sister Naho waltzing into the bath with a cheerful 'Mom said to get in with you, so we're not wasting money on heating' — and suddenly three fourth graders are crammed into one tub with every boundary unravelling fast. Squeezed close between the two flustered boys, innocent Naho seems perfectly content with the arrangement while poor Tomo fights to keep his dignity and his composure intact. But when he finally stands, one accidental reveal leaves Naho covering her mouth in wide-eyed wonder and Tomo lamenting that he's done for — a sweet, blushing comedy of childhood embarrassment.
