Amateur mature women are invited out to a lewd, erotic AV viewing party just the two of them. Perhaps because they are excited by the lewd acts in the actual AV, they are quiet and restless. The Kokoro mature women blush as they stare at the screen. They seem to be glued to the actor's penis. They don't refuse the devil's hand that starts touching them as the AV gets exciting...the tension of being in a closed room is irresistible.
