A simple, reserved wife has opened her mouth to S&M! Shiori is excited when she hears about a romantic date project. First, the two go on a date around town and then head to the studio for some intimate sex…or so you'd think, but it suddenly turns into ******* and finger-fucking! With tears in her eyes and gagging, she is told the true plan! Further on, she goes for a walk outdoors wearing a fucking mask, is tied up in nature and subjected to incontinence toy *******, and then has S&M bondage sex at an S&M hotel! Spanking so hard it feels like her ass is going to be torn off, and fucking so hard it feels like her throat is going to break. A new pleasure she discovers beyond the pain awakens her to a new self in this S&M training documentary!
