Boku ni Harem Sefure ga Dekita Riyuu

An inexperienced young man with no history of romantic relationships finds his quiet life upended after a routine trip to the local convenience store. There, he unexpectedly crosses paths with three outgoing girls from his class. Upon discovering that his apartment is just around the corner, the trio boldly invites themselves over, barging into his home without hesitation. With little regard for his privacy, they immediately begin rummaging through his cluttered room in search of something to pass the time. Their search quickly yields far more than innocent entertainment. The girls uncover his hidden stash of adult magazines and explicit videos, instantly shifting the atmosphere of the visit. Rather than expressing disgust, their curiosity takes over, steering the conversation toward highly provocative territory. They openly debate intimate techniques, with one even demonstrating her theories by mimicking the act on her own finger to illustrate what supposedly brings a man the most pleasure. Overwhelmed and entirely out of his depth, the young man watches the scene unfold in stunned silence. Despite his desperate attempts to remain composed, his body betrays him completely, leaving him visibly aroused. His frantic efforts to conceal his reaction from the three girls prove utterly futile, trapping him in an inescapable situation as his ordinary evening spirals into something far beyond his control.
