1:00, with Kristina; not severe

01:00

"What do you mean, I can't take my bag in?!"

Kristina held in a wince at the pitch of the girl's whine. "I mean, store policy says we don't allow bags in the dressing rooms. Anti-theft policy."

The blonde teen's eyes narrowed. "Are you, like, accusing me of something?"

Kristina's eyes twitched, but she managed to keep from rolling them. "Of course not, miss. But I have to enforce the rules."

The girl raised one hand, one finger already extended. "Enforce this, fascist."

This time Kristina didn't bother restraining herself. Her eyes went all the way around, while the teen's bulged in outrage.

"You know what? It looks like I need to show you your goddamn place, you fuckin' cog." The blonde reached down to her pink skirt and flipped it up, revealing a moderately sizable bulge in her underwear - perhaps eight or nine inches.

"...Okay. Sure." With a single smooth motion, Kristina unbuttoned her pants and jerked them down to mid-thigh, allowing her fourteen-inch erection to bounce free. "Well?"

The teen stood frozen, her eyes like dinner plates.

Kristina could see it in her eyes when she made her decision - not that she would've been allowed to back down at this point anyway - and she sidestepped the girl's charge, letting her slam facefirst into the dressing room door.

While she cried out in pain, Kristina stepped up behind her, pulling her arms behind her back and sandwiching her against the door. The teen tried to struggle, but to no avail; Kristina held both the girl's arms in place with one of hers, while she tugged the customer's thong out of the way.

A well-practiced shove landed more than half her length inside the blonde's asshole, eliciting a high-pitched wail of pain, and a second shove brought her in up to the hilt.

All in all, the disciplinary session lasted fifteen minutes, after which the teenager was allowed into the dressing room.

After she was done, the subsequent 'cavity search' lasted another thirty.
