Misty becomes your toilet.

You feel your cock throb with the desire to relieve yourself and you look at Misty.

"Do you want to feel masters water gun?" You say, mentally slapping yourself for making such an overused joke

"I live to serve you, I am your robotic anime cock slut." she says, squeezing her breast and playing with her nipple as she fingered herself in front of you.

"Then drink every drop Im about to give you."

You forcefully grab Mistys head and **** your cock into her mouth, still covered in her juices and a bit of your cum, and start to urinate into her. You hear a mumbled moan, and then soon the sound of rapid gulping as she attempted to drink down every drop. Her cheeks puffed out as her mouth filled with your piss and some started dripping out the side of her mouth, but being a robot, thankfully, she was able to guzzle down most of it. You let out a contented sigh as you pull out. Misty lets out a gasp for air and pants heavily, but then licks her lips and gazes up at you with a sexy smile

"Thanks for the drink Master...next time you'll have to fill my pussy with it too."

"You're welcome. I hope you feel refreshed now because I'm not done using you"
