Kristina, a few minutes earlier

"What do you expect me to do, young lady?!"

Kristina felt like she was getting a headache just from the strain of not rolling her eyes. "Ma'am, I already said, there isn't anything I can do for you except ask you to wait."

The blonde woman sniffed. "Wait how long, until you people can close down and stagger home?"

Before Kristina could interject, the customer continued. "That may be acceptable to you and your little friends, but I came here to make purchases, and I will not tolerate delays."

Kristina's frustration was likely audible in her voice at this point. "It's out of my hands, miss, the dressing rooms are all full. I can't just kick someone out for you no matter how much you need to use one."

The woman opened her mouth again, then paused, and a momentary look of pleased realization crossed her face. "Well then... I suppose I don't have a choice, do I?"

Kristina braced herself, but the blonde made no move towards either the employee or the door. Instead, the older woman shucked her own pants in a single smooth motion, stepping easily out of them and leaving herself clad in only a pair of small pink panties from the waist down. Kristina's mouth hung open in shock.

"What?" The woman's voice almost sounded sincerely confused, with only the lightest pink tinge to her cheeks to give away her awareness of the inappropriateness of her actions. "I need to try these on before I decide if I'm going to buy them, so if you won't allow me into the dressing rooms, then this would seem to be my only option."

"I- M- Y- you can't- I'll- that-" Kristina stumbled over her words more severely than she'd ever stumbled over anything, her hands waving. Then the pink panties joined the crumpled pile on the floor, and Kristina's words abandoned her entirely.

Leah, the store manager, was the best-endowed futa that Kristina knew, or that any of the other staff did. Over the years there had been a few customers that came close, but nobody had ever managed to outsize the stocky redhead's eighteen inches.

Without thinking, Kristina took a small step back, some animal instinct screaming at her to get away.

The half-naked blonde in front of her was eighteen inches if she was a single inch, and the brunette employee felt her knees knock together once. She took a breath, and a strong, hot musk twisted its way up her nose, making her eyes water. She was unable to stop herself from whimpering softly as she felt her pants bulge outward over her own hardening shaft.

No! She shook her head, abruptly and violently. What the hell was she doing?! This was the roughest, toughest, hardiest store in the whole company, and she wasn't going to disgrace her store or her coworkers just because of some cocky exhibitionist waving herself around.

No, no matter how gifted she was, she'd squeal just as loud as any other customer Kristina'd disciplined once the employee got her on her-

Kristina's thoughts were interrupted as the woman stepped calmly forward, took Kristina by the shoulder, and pulled her into a passionate kiss, the older woman's tongue pushing its way into the employee's mouth. The customer's other hand reached down past the waist of her work pants to wrap around her own smaller erection, while the first hand moved down from her shoulder to squeeze her ass through her pants.

It was over a minute before the woman pulled away, leaving the stunned Kristina to blink rapidly with eyes now the size of dinner plates. Her cock was leaking precum into a new stain on the front of her pants, while the customer's cock had left its own, larger stain on the part of Kristina's shirt just below her breasts.

Kristina raised one hand, her pointer finger extended, but the woman ignored her and reached out again, unbuckling the employee's pants and yanking them down, eliciting a high-pitched squeak as she now matched the customer's bottomless state.

"Oh, my." The blonde smiled down at Kristina's smaller penis a little mockingly. "I suppose I shouldn't have expected anything better from such a young person, but that does make things easier - you just need to be shown your place, don't you?"

Words refused to come out from Kristina's mouth, her face now dark red with embarrassment.

The older woman stepped forward again, reaching out and casually turning Kristina around by the shoulder. One hand groped her tit through her shirt, and she could feel the customer's hot, hard erection as it settled between her cheeks.

Too late, she reached out for the buzzer on the wall next to the dressing rooms. She needed help, backup-

Eighteen-plus inches of meat thrust straight up her ass, and Kristina's shriek of pain hit such a pitch that it was no longer audible to humans.
