Rei, a married woman who is frustrated by the lack of sex with her busy husband, has an affair with a man she met on a dating site at home while her husband is away, in an attempt to soothe her throbbing groin. Rei is addicted to the pleasure of sex after a long time, and they continue to have affairs while her husband is away on business. One day, she invites the man over to have sex with her, but he gives her drugs and plays with her body with his friends. He makes her cum with a large number of vibrators and electric massagers, climaxes with a deep throat blowjob, and then makes her cum with continuous follow-up fucking.
