president, you are the degenerate one here...

 

[caseo78]

Thanks for the chapters as always!
Ueno needs to control her desires for this invention to work.

 

[RandomFanguy]

You know what I noticed, Ueno is always changing up the legwear she has on. I can appreciate that.

 

[rc1138]

She's just that easy turn on?

 

[zaib]

[Simpleton]

I'm agreeing with rc1138. The "mysterious spirit" the device measures is probably the victim being stimulated, and in this case Ueno got too excited too fast.
