Klaus, is this really you?

It came still in Klackner's male voice.

"K-Klaus!?" came from Martens in disbelief.

"Yes! Or would Frau Brandner do something like that?" came when she turned around and presented herself to the two like that.

In doing so, 'she' emphasized her shapely, if perhaps a little oversized, buttocks. In any case, it made itself beautiful in her tight-fitting pair of panties.

"Klaus, is this really you? How do you feel?" Martens asked.

"It's a bit drafty in here, otherwise...," Klaus paused to squeeze Val's exposed butt cheeks and giggled to himself, his laugh coming out lower than either he or Walter anticipated. "What do you think?" he asked them, trying to make his normal baritone squeaky and effeminate.
"It's impressive," Martens says as he examined the curvaceous body of his transformed employee, "but I'm noticing one issue!"
"Yeah, I didn't get the voice right," Walter sighed, "I'm still ironing out some of the kinks."
"NONsense," Klaus admonished, his voice cracking like a teenage boy's. "WAit whAT othER 'KInks'?"
"Stop trying to talk like a woman, Klaus. Just use your normal voice, that is an order!"answered Martens before turning on the hapless inventor,"But like he, er um she said what kinks are there? Is Klaus safe?"
