IMTT-007 - Married aesthetician discovers anal pleasure, corrupted into a bitch through training

The premise is Hitomi Rei playing a male aesthetician. Since she's a housewife, I think they could have leaned more into the sense of taboo or her relationship with her husband. Why was the trainer so obsessed with the anus? When taking off her underwear at the bar, he should have checked for stains before smelling it. Also, in the final aesthetic scene, it would have been nice if there was an anal penetration option instead of just licking. Still, the ending is solid, and Hitomi Rei's mysterious smile is really striking. It's a well-crafted piece.
