[Caramel Milk (Nishikanda Maneko)] Suou-san no Katei no Jijou (Persona 2)

Katsuya and Tatsuya, brothers bound by both blood and desire, find their relationship fracturing under the weight of hidden longing, as Katsuya confesses his desperate need to claim what another man wouldn't—"I want to do with you what he wouldn't do." Tatsuya, caught between propriety and raw temptation, is stripped and overwhelmed, his lithe body yielding to his older brother's advances on the bed they've shared since childhood. As their heated encounter escalates, Katsuya's final breathless command seals the brothers' taboo union in a haze of sweat, trembling limbs, and forbidden fulfillment.
