Ikan♂Chikan: Hentai darake no Manin Densha

Mao harbors deep feelings for his childhood friend, Riku. Even after enrolling in university, he chooses to commute from home rather than move into a dormitory, unwilling to sacrifice the proximity that keeps him close to the person he loves most. However, this daily routine comes with a hidden burden. Every morning on the crowded train, Mao is subjected to unwanted advances from behind by an anonymous assailant taking advantage of the packed carriages. Though he struggles against these daily violations, Mao finds himself trapped in a deeply confusing internal conflict. Despite his resistance, his body betrays him, secretly responding to the illicit touches with unexpected pleasure. He is caught between his genuine devotion to Riku and the overwhelming physical sensations he experiences during his commute, leaving him torn and unable to confide in anyone about what happens on the rails. As the boundary between distress and secret desire continues to blur, Mao's situation grows increasingly precarious. The crowded train has become a battleground for his conflicting emotions and bodily reactions. With no one aware of his silent torment or his hidden arousal, the question remains: who, if anyone, will step forward to rescue Mao from this relentless cycle of temptation before it consumes him entirely?
