Chapter 26 At That Time, the Slaves… ① – Tsukigase Sayaka
Edited by: Kanaa-senpai
In the depths of the test dungeon’s lake field training facility, second-year student Tsukigase Sayaka, with her short, boyish blue hair, stood among her peers.
”Alright, ladies! Next up, let’s master deep throating after a stroke!”
At the succubus trainer’s enthusiastic command, the girls paused their licking. They then buried their faces into the life-sized doll’s crotch, where a 15cm prosthetic penis was attached, wearing only their panties. The doll, crafted from silicone-like material, stood firmly anchored to the floor of the Grand Hall, where over a hundred girls were gathered. In unison, they took the prosthetic into their mouths and began stroking it rhythmically.
”Come on, girls! Get it deeper into your throats!”
The succubus trainer urged, forcefully pushing the head of a first-year girl.
”Guh, gah!”
The girl’s face contorted in obvious distress. Witnessing this, the rest of the girls desperately tried to avoid drawing attention, forcing the prosthetic deep into their throats. Sayaka’s best friend, Sanae, tears welling in her eyes, did the same. Sayaka followed suit, despite the discomfort.
”Nice job! That face is perfect! Men get really turned on by that. Oh, wait, don’t pass out on me.”
Noticing the girl’s face turning blue, the succubus trainer released her head.
”Gah, ugh, cough, cough!”
”Oh, don’t throw up. Men hate that. Come on, keep going. Or do you want to end up as a Soul-less Doll²?”
”Y-yes! I’ll keep going!”
The girl, now pale for a different reason, forced the prosthetic deep into her throat. The succubus trainer watched with amusement. Of course, the girl would be desperate. The succubuses would kill them without hesitation.
Nine days ago, the classroom suddenly went dark, and Sayaka woke up in a cave.
The Succubus Queen announced she’d trapped the school to create a test dungeon. The boys were testers, and the girls were their s*x slaves.
The teachers protested, but the older ones were beheaded by the succubuses, along with the cafeteria and dorm staff.
It was Sayaka’s first encounter with death. The kind teachers, the energetic cafeteria ladies—gone in an instant.
Tears wouldn’t stop, and her body shook with fear.
She realized her underwear was wet too. It wasn’t just her.
Almost everyone there was the same.
Later, she heard that women over 40 were to be disposed of from the start. No s*xual value, they said.
Paralyzed with shock, the succubuses introduced them to a human Soul-less Doll—a girl their age, cute but lifeless, following orders like a puppet.
They forced her to lick their boots, threatening to turn them into dolls if they didn’t comply. Soul-less Dolls are sealed in crystals, dropped in dungeon chests or as rewards.
Testers use them for servitude and s*xual release.
Even if they aren’t turned into dolls, they’re still slaves, marked with a crotch tattoo paid for in DP⁴. The only difference is whether they’re alive or dead.
Sayaka doesn’t want to die.
She wants to escape, see her family. Becoming a doll means losing herself.
If she dies, her body will be used by the boys.
She hates that thought. Honestly, she hates being a s*x slave too.
But she can’t disobey.
Her body moves on its own when commanded. If bought by a boy, she knows what awaits.
Still, it’s better than dying or becoming a doll. If she stays alive, she can see her family again.
Everyone feels the same. That’s why they train so hard.
After oral training, they took a short break, then practiced riding position on the doll, now lying down with a smaller prosthetic.
They gyrated their hips and pistoned up and down. Being a virgin increases their value, so thankfully, they could keep their panties on.
It’s been nine days since Sayaka woke up in the cave and was brought to this lakeside mansion. They’re divided into two groups.
Mornings are for running around the lake and strength training to maintain their Pro-Potion⁵. Afternoons are for endless s*xual training.
This place looks real but isn’t. The lake, the grass—at first, she thought they were in Europe.
But the succubus trainer told them it’s a space created within the dungeon.
A field-type dungeon layer, the animation and voice acting exchange students explained. No exit in sight.
Running is hard for the artsy girls and the heavier ones. If they don’t meet the distance, they skip meals.
And the distance increases daily.
The food is already scarce and tasteless. Everyone runs desperately.
In this dim, cloud-covered space with no exit, they train daily—physically and s*xually.
All to maintain their Pro-Potion or lose weight, making them more appealing. And to satisfy the boys with their skills, so they’ll want them more.
If they’re not bought, they stay here, training on scraps.
Unsold slaves are disposed of when the test ends, the succubus said cheerfully. So work hard.
The boys see their faces and measurements in real-time.
It’s embarrassing, but necessary to be bought. If she’s bought, she’ll do anything to help her friends, especially Sanae.
She’s too proud to flatter men, so without Sayaka, she’d suffer. Sayaka needs to be bought first and plead for her.
But who will buy her? If she could choose…
While pistoning on the doll, she looked at the screens on the wall, showing the boys fighting. They’re battling to buy them.
A reminder to be grateful? She searched for him—Guard-san. He fought a two-legged dog, alone, stronger than anyone.
She’s watched him daily. Six months ago, at the gate, he seemed scary.
But during summer camp, he saved a drowning underclassman from the pool. He knew first aid, even dislocated her shoulder to save her. He comforted her, carried her to the infirmary, and encouraged her.
The underclassman was smitten. With his scar hidden, he’s handsome.
She started greeting him daily. He always smiled back. No longer scary.
Now, watching his broad back, she felt a tingle. If she must be a slave, she wants him to buy her.
But it’s unlikely. So she’ll work hard, catch his eye. Determined, she moved her hips vigorously on the doll.
