How does a Futanari Junko manage to trick all the girls in her class into activating the magical artifact?
"Oh, it's rather simple really!"
Junko laughed quite a bit, having simply left the boombox in the middle of the classroom, hours before anybody else would arrive for class.
As the girls made their way to the classroom, the first thing they'd notice was the golden boombox. Of course, some of the girls were a bit confused, though... what was the worst that could happen? It was a bit weird that none of the guys were here though, not even Chihiro.
Sayaka would be the one to turn the boombox on, out of simple curiosity. And, soon enough, the hypnotic beat would begin to work its way through each of the girls' ears, starting with Sayaka. It felt like her body had begun to move on its own.
"H-huh? Wh-what're you doing, you damn Idol Skank?!" Toko began to spit out, before her body began to move as well.
One by one, the girls would start shaking their nice, plump asses. Some would protest in indignation, such as Celeste, in some attempt to keep her dignity.
Others... seemed to just try and enjoy the ride.
For minutes on end, their asses continued clapping together, each girl getting closer and closer, before finally cumming.
"Oh, fuck... That was so hot..." Junko said, finally revealing herself, stroking her nice, fat cock to the sight... "Now, how about each of you do it again?"
Before any of them. could protest, the music started again, each girl being forced into the process once more...
Today was going to be a long day.
