[Equal] Nukegake (Hatsuiku Collection) [MrBubbles]

Natsuki's plans to laze through summer homework collapse when Shou and Ken-chan show up at her door and drag her to the river, and her still-damp school swimsuit proves impossible for the two boys to resist. Fumbling curiosity over her heavy chest quickly spirals into a full afternoon on the riverbank — her riding one boy with her mouth stuffed full, then taking both of them at once — until the confession that makes her tearfully admit she was happy all along because they said they love her. Back in the classroom with their assignment still unfinished and the teacher furious, Natsuki lifts her skirt with a smile: summer isn't over yet.
