You work in a office, casually, you stand up walk to take some water but suddenly you feel a shaking sensation deep in your insides, who make your legs squirm slighty. Trying to composse yourself and breath, you just keep with it. Coming back to home, you find Verosika and her playful glare, "¿Did you enjoy the little "shake"?", she ask, playfully, holding the bottom.

Days ago, you and Verosika play along a game which you lost and make a deal with her. A kinky deal.
