The sound of Eiki Shiki's moan instantly drew the attention of everyone in the restroom. They all turned toward the source.
"Lady Eiki, everyone heard you. It looks like we can't hide it anymore," Kars said, his voice loud and clear, making it impossible for Eiki to pretend it was a hallucination.
"Want to show them?"
"No... no... a situation like this... how can I... aaahhh!"
Eiki shook her head; the shame of being seen in this state was overwhelming. She tried to muffle her voice, but Kars gave a powerful thrust that forced a lewd scream from her lungs, audible to every woman outside the stall.
The onlookers blushed furiously. They couldn't believe their respected Yama was in a public restroom having sex with a male, making such depraved sounds.
Curiosity got the better of them. They wanted to see the Yama's face in this state. Kars obliged them by kicking the stall door open. The women gasped as they saw their superior, completely naked and flushed with lust, her buttocks grinding against a massive cock that was churning her pussy.
"Aah~ don't... don't look at me..."
The sudden gaze of so many eyes flooded Eiki with an unprecedented sense of shame. She buried her face in Kars's shoulder, yet her hips began to move even faster. The humiliation was acting as a powerful aphrodisiac, making her body even more responsive.
"Lady Eiki's vagina is getting so tight. Does being seen really turn you on this much? Maybe they should get a better look. Hey, do you all want to join in?"
"C-can we?!"
The invitation was irresistible. Driven by the allure of the cock and the chance to be intimate with the Yama, the women flocked forward.
"Of course. Lady Eiki will be happy too, right?"
Eiki only moaned in response, which was answer enough. One girl rushed in, grabbed Eiki's swaying butt, and began nuzzling her face against it.
"Aah~ Lady Eiki's ass! I've always wanted to touch it! And such a pretty puckered hole."
The girl kissed Eiki's anus and then slid her tongue inside, making the Yama's screams reach a new crescendo. More women crowded into the stall, stripping naked. They began to serve both their respected leader and the boy who had brought them this unexpected "gift."
"Aah! Lady Eiki's pussy and this cock... they're both delicious..."
"Lady Eiki's breasts are so cute. Let me taste them."
"Give me your tongue, Lady Eiki."
"And you, little boy—do you want tits, a kiss, or our pussies? Don't be shy, you can do whatever you want to us!"
The commotion in the restroom grew until a long line had formed outside. The sound of moaning didn't cease for hours, continuing until Kars finally fell asleep from exhaustion.
Eiki Shiki lay slumped against Kars, her body covered in semen. Thick fluid leaked from her vagina and anus. Her eyes were vacant as she gasped for air. She didn't know how long they had been at it; she had lost count of her orgasms. At some point, she had even been double-penetrated by Kars and someone using a strap-on modeled after him.
When they finally woke, they were back in Eiki's bedroom. Thinking back to the absurdity of the previous hours, Eiki covered her face in disbelief.
"I can't believe those girls would do that... fine! If you like it so much, you can play as much as you want! You had your fun playing with me while slacking on the job!!"
When Kars later returned to the restroom area, he found it transformed. The walls now featured "Glory Holes" where girls would wait, naked from the waist down, with their photos posted above so Kars could choose his favorite.
In one such hole, the lower half of Eiki Shiki was visible. Above her, Komachi stood blushing, lifting her skirt to reveal a cock identical to Kars's. She shoved it into Eiki's mouth, and together with Kars, they enjoyed the Yama's body from both ends.
