"Karyn, you will not remember having seen me in your room when you got out of the shower" you say "And for the next hour you cannot see or hear me, but you will continue to do as I say as if you could hear me."
Karyn's eyes glaze over slightly as she adjusted to not being able to see you. She had one towel around her body and one towel in her hand, drying off her hair. She walked over to her full body mirror and looked at her self.
"Karyn, take off your towels." Karyn loosened the one around her body and tossed them both in her clothes hamper. Thinking she did this on her own free will, she continued to look at her self in the mirror from different angles. She grabbed her boobs and tried adjusting them, seeing how they'd look from different angles.
"God, these breasts are so huge. I can't believe I made that stupid wish." Karyn said as she bent forward to see how much they forced her body forward.
You meanwhile were getting excited. Karyn was naked in front of you practically doing a strip tease.
