A married woman with big tits is troubled by her male neighbor. Six months ago, she invited him into her home for several days while he was renovating, and since then, her large breasts have been constantly groped. Originally in a sexless marriage, she began masturbating to relieve her pent-up desires, but was caught by the neighbor. After that, he started barging in freely and relentlessly fondling her breasts from behind. Even when she panics and pleads, "No, stop it...!!", he ignores her and continues without restraint. This situation deepens her distress while profoundly affecting both her body and mind.
