[ENG Ver.] Extracurricular Excursion ~The Sultry Night My Girlfriend Was Plundered~

Editorial Review

★3.7 / 5 — henhenta editorial rating (our own assessment, not the DLsite official user score)

Beach-trip netorare with a “cheating in the same room” setup, this sits in a well-worn corner of the adult doujinshi landscape, where the appeal comes from proximity and risk rather than elaborate plotting. The one-month relationship timeline places it in the “fresh couple, fragile bond” subset, which tends to emphasize vulnerability over long-standing betrayal.

What sets it apart is how deliberately the synopsis builds its tension. The opening day is warm and affectionate, with kissing and a playful handjob between Yukari and her boyfriend, so the later turn lands as a contrast rather than an abrupt switch. The core scenario, with Yukari under the sheets beside another man while her boyfriend is nearby, is driven by suppressed moaning, hazy consciousness, and a heroine persuaded by flattery she isn’t used to hearing. Her characterization adds a layer: a tanned, energetic track and field athlete who is treated like “one of the guys” yet is secretly a curious closet pervert. That gives the persuasion plot an emotional hook, since the other man’s attention speaks to something she rarely gets. The seaside heat, sweat, and glistening skin supply a strong summer atmosphere. On the practical side, the English release comes in both JPEG and PDF formats, which is convenient for different reading setups.

Readers who enjoy netorare built on secrecy, suppressed reactions, and a sporty, tomboyish heroine with a hidden side will get the most from it.

Verdict: a tension-forward summer NTR piece whose “don’t make a sound” premise and contrasting heroine make it an easy pick for fans of the subgenre.
