SDMT-239 - SOD New Weapon: Magic Mirror Fitting Room - Groping a girl who is changing clothes

A hidden camera prank set in a clothing store where all the fitting room mirrors are two-way mirrors (the store itself is a set). The moment a female customer gets down to her underwear, an actor waiting behind the mirror grabs her breasts from behind. However, from the second person onwards, the execution gets sloppy, with actors just walking in from the 'front.' Furthermore, in the middle, they start doing 'short skits' between the actor and the customer, completely abandoning the original concept. The actresses playing the victims don't resist at all and just endure having their breasts groped, which is quite surreal. Also, there are no penetration scenes; it's basically just 'groping only' until the end.

Who is the second girl? I think she appeared in a pizza delivery-themed video too, she's cute.

It's exactly what the title suggests. It's just a guy groping a woman from behind while she's trying on clothes in a fitting room. There's some crotch touching, but 90% of it is just groping. I expected more of a 'happening' style plot, but the guy in the mask just makes jokes while he does it, so it's basically a comedy. The girl resists at first, but eventually just gives up. I was hoping for more of a prank-style scenario, so it was a letdown.
