Yes

Just as everything: the vibration, the stimulation, the sensory deprivation, are becoming unbearable and you're worried that you just signed your life away... it stops. The latex retreats all the way and you find yourself in a new outfit, one that looks more like Domanatrix attire. All black latex as before except now all that you're wearing are knee high boots, a corset that shows off your modest breasts, and gloves that cover from your fingertips to your elbows. Still breathing heavily, you look up at Mary who seemed to be masturbating on the bed as she watched you, now with a slightly disappointed look on her face.

"Well... Shit. Congratulations new Mistress! i look forward to serving you!"

still reeling from the now absence of stimulation where moments before that's all there was, you almost don't notice Mary taking your collar off and handing it to you.

"As my new owner you may now put my collar on, giving me completely to you until the day you either die, free me, or return me to the Island to continue my work here. Any Questions?"

You put the collar around her neck and her outfit immediately responds, changing it into a full body latex outfit like the one you were just wearing with openings around the nipples and at the crotch area.

"i have a question, yeah. the test is over right?"

"Yes Mistress."

"So there's nothing saying i can't orgasm?"

"Correct."

"well then my new pet... get licking."
