Mei's machines

"Mei, why am I here?" Itsuka Kendo looked dubiously at the humming machine in front of her.

"To help me test my babies of course!" The pink haired inventor answered like it should be obvious. The girl had called Kendo down to the lab to help her out, but had no given any instructions past "stand here with your legs apart"

"Ok, but what is this suppos- AEEEIIIIE" whatever question Kendo about the strange machine had was cut short when a boxing glove shot out and slammed into her pussy, her track suit doing nothing to cushion the blow.

"Success!" Mei cheered as she fell over, cupping her cunt as pain shot through the girl. "My Cuntbuster 1000 works!"

But just as fast as the happiness came the girl's face suddenly turned serious.

"Hmmmmm, needs some adjusting." Mei walked over, fiddling on a few knobs before grinning maliciously down at Kendo.

"Time to test these changes."
