This may be what is happening to your wife right now. These are all married women with uninhibited lower halves, addicted to pleasure massages, frequenting them when their husbands are out, enjoying one-night adventures at class reunions, secretly rendezvousing with the man next door when their husbands aren't looking, and having affairs with their fathers-in-law. S1 actresses such as Saki Okuda, Tsukasa Aoi, Yua Mikami, and Moe Amatsuka perform a variety of vulgar and erotic adulterous sex scenes that culminate in climaxes with tongues entangled in intense, dense performances.
