A plump housewife named Izumi Sakuma, who has been sexually frustrated for seven years with her husband, fantasizes about being taken by many men. As she sits on the tatami floor in a dimly lit room, her desires become increasingly evident. The men touch and undress her, caressing her ample breasts, causing her to breath heavily. She becomes aroused and begins masturbating vigorously at their request. When given an electric massager, she uses it to pleasure herself intensely. Soon after, another man surprises her with a vibrator, sending her into multiple orgasms.
The men then proceed to take turns pleasuring her orally and anally using various toys such as dildos, rotators, and electric massagers. They also ejaculate onto her face and body while continuing their relentless assault on her senses. Finally, they fixate her in a position over a toilet bowl where several more men join in to violate her thoroughly. Their actions include covering her body with lubricant and stimulating her erogenous zones until she experiences multiple climaxes and squirts copious amounts of fluid.
Throughout this intense encounter, Izumi's moans echo through the room as each man takes his turn filling her up completely. Despite being exhausted from all the non-stop action, she remains eager for more and even begs them not to stop. In the end, dozens of men have left their mark on Izumi's body, leaving her satisfied yet yearning for more of these taboo encounters that have transformed her into a true "mature woman" who enjoys being used by strangers.
