[Sebire] How Sisters Go from Friendship to Romance [EHCOVE]

Two sisters arrange an ordinary afternoon meetup, but one returns transformed into a boy, and a single breathless kiss tips their easy companionship into something far hungrier. Shy curiosity melts into a tender first time as she discovers the bitter-salty taste of him, the warmth of his release on her tongue and skin, and the way he trembles apart under her touch. Spent and shaking, he still can't refuse when she leans close and sweetly asks if he can go again.
