Frozen marital relationship. Her wife, Aika, was feeling her loneliness. Without a night with her husband, she has saggy skin and fat as she ripens. Corrective underwear I secretly bought... One day, my husband's brother, who is older than me, sees his underwear. A brother-in-law who can't suppress his excitement at his sister-in-law's obscene appearance. Two people who escalate by drowning in forbidden acts while knowing that it is an unforgivable relationship.
