Sakura, a full-time housewife suffering from severe lower back pain due to recent household fatigue, one day her husband brings home a flyer for a business trip massage that was in the mailbox. The flyer promises extremely low prices and no payment if no effect, so Sakura decides to call for the massage. Unaware that it is a trap set by a despicable masseur... The pressure points that are supposed to help with back pain initially around the waist start moving towards the groin. By the time she feels discomfort, it's already too late. Her underwear is overflowing with a large amount of semen.
