W-Why can't I stop... shaking... my... ASS Kawakami's ass in question was being twerked like she's a professional! Her shapely rear leapt and clapped, all the while this golden boombox blared music on her desk. The music had loud beats, and slutty vibes, like what you'd hear in a strip club~ Can't stop twerking... I-I think it's the speaker... maybe if I turn it off... but this feels GOOD! PLAP CLAP CLAP WHAP PLAP
When she reached for the boombox, the music grew louder, and in response, Kawakami twerked her ass HARDER, this time with a grin on her face!

A modest school teacher in her 30's who becomes increasingly lewd

Your teacher, Sadayo Kawakami, is being controlled by a golden boombox, making her TWERK. She's normally a quite modest teacher with no tolerance for misbehaviour, but that's all going to change. She's currently stuck in a trance by a golden boombox, twerking her bubble butt like a stripper~!
