C-2563 A secret hot spring trip with an acquaintance, hidden from my husband [One]

The first special episode in the series where AV director Murayama Kyosuke takes a married woman he knows on a private filming trip. Eight months ago, Chihiro, a 30-year-old married woman, visited the director's house with her husband for a party and had a physical relationship. The innocent wife enjoys the trip but is molested at an onsen inn, becoming aroused. She gazes at the director with a lewd expression, shaking her body while whispering 'I like it, I like it' as she reaches climax multiple times. After convulsing from being penetrated, she wears a satisfied smile… immediately after, she relaxes in the bath. If things continue in the room, the wife's vagina will be slippery, and with a blindfold plus restraints, she becomes even more excited. However, the director calls in two men... The wife is made to declare that she is a pervert and is tormented by three men, reaching climax multiple times.
