[Lyrical Seeki] Jinrui Otokonoko-ka Keikaku Natsuyasumi Hen ~Shotaimen no Otoko no Ko-tachi to ikinari Hatsu-Ecchi!?~|Human Traptality Project Summer Vacation Arc ~These Boys are Suddenly Losing Their Virginity After They Just Met!?~

Two inexperienced men meet during a seaside trip, and one’s attempt to understand women by wearing a flower-trimmed bikini soon turns their awkward introduction into an intimate first encounter. Bare-chested tension by the rocks, teasing dialogue, and increasingly close physical contact frame the comedy as their careful boundaries collapse. A bonus page extends the joke with jealous banter and a promise that their vacation embarrassments are far from over.
