A shy guy has a lover, Tsumugi Akari, and they've known each other for over a month. His shy nature makes him rarely talk to his girlfriend and they haven't even kissed. Tsumugi quickly gets bored of this affair and she finds herself at the park sitting and drinking beer. A good flower digger at school came to sit next to Tsumugi and soon she was able to seduce her and record the video. And about a month later, the senior guy showed Tsumugi's boyfriend his flirting exploits with that video, and the boyfriend was startled and distressed when it was his girlfriend. And from then on, he only knew how to silently watch his girlfriend being fucked by his seniors in agony.
