Back in the school basement, the teacher stood there puzzled by the gift lying in front of him. It was a black leather mask with a large tube and funnel connected to its mouth. He turned around to face his students, Arima and Yuki, who suddenly sprang into action.
Without warning, the two girls pounced on their teacher, tearing off his clothes in a fury. Arima then grabbed the mysterious mask while Yuki picked up a roll of duct tape. They quickly forced the helpless man into the leather contraption, securing his arms tightly to the tube using the tape. His legs were bound together too, leaving him completely immobilized and at their mercy.
As they stood over him, their cruel grins spread across their faces. "Now, you're really ours," Arima sneered. Yuki nodded in agreement before reaching down and pulling off her panties. She spread her legs wide in a show of dominance as Arima reached for a large syringe and a bottle filled with milky white fluid.
With determination in her eyes, Arima began emptying the contents of the syringe into the funnel connected to the mask. The viscous fluid made its way down the tube and into the teacher's unwilling mouth. As he gagged and struggled against his bonds, Yuki watched on, her stomach churning with anticipation.
Finally, after what felt like an eternity for the terrified teacher, Arima picked up the syringe again. This time, she approached Yuki with it, who patiently waited with her legs spread wide open. After filling up the syringe with milk from her overflowing bladder, Arima inserted it into Yuki's tight butthole.
Slowly but surely, Arima emptied the syringe into Yuki's bowels. The warm liquid filling her up from the inside out. Yuki grimaced in pain, but also in pleasure as she felt the intense fullness spread throughout her body. As Arima pulled out the syringe, it left behind a trail of clear fluid oozing from Yuki's ass.
She took a moment to gather her breath before pushing her bulging stomach forward, sending a massive wave of creamy, brown scat infused milk blasting out of her asshole and down the funnel into the mask. The once milky white liquid was now murky brown and teeming with chewy chunks of feces.
The teacher squirmed and gagged as he felt the warm, sticky mess slide down his throat. It was revolting, yet he couldn't help but feel a strange pleasure coursing through his body. These two girls had completely taken control of him, and there was nothing he could do about it.
As they watched their helpless teacher struggle to swallow every last drop, Arima and Yuki couldn't help but smile. They shared a knowing glance and proceeded to him tie him up tighter with the remaining tape, ensuring that he wouldn't be able to escape or even move for the rest of the day. Their sickening game was far from over.
