[Flicker10 (Kuronyan)] The Last Day of Summer [Team Rabu2]

On the last day of summer break, a young man reunites with Yuki-nee-chan, the busty older cousin who was his childhood playmate and possibly his first love, and a splash fight in the river leaves her clothes soaked and clinging to every heavy curve. What starts as teasing play in the water escalates outdoors against the trees, where he finally buries himself inside her, confessing years of longing while she gasps for more. Their secret doesn't end at the riverbank, as heated rounds indoors leave her moaning beneath him—and the season of their forbidden tryst closes with consequences that will last far beyond summer.
