Pose as her assistant

You pull yourself out of bed and stretch, basking in the pleasant numbness of your dick. That was easily the best sex of your life, and it took maybe 10 minutes to, uh, expand your nurse's duties.

... Duties.

Oh, baby. You have an idea!

You slip into the bathroom behind her, and Nicole is cleaning herself with a towel, sponging around to clean off the grease. She glances at your reflection and averts her eyes, trying not to show her elation. As you ease up behind her, you wrap your hands around her hips and interlace them at the front of her waist. She smiles a little and gingerly rubs her bum against you as she cleans her face.

You lean in and push her hair aside to nibble at her neck a little. She laughs and swats you away, and in mock disapproval, you blast her face without warning. The green fog assaults her senses and your nurse's (half-hearted) cry for mercy dies on the tip of her tongue. The towel drops to the floor. Her muscles loosen. You nibble her neck again.

"I'm your assistant, Nicole. We've only worked together for a few months now, but I've bedded you a solid 20 times since we first met... you just couldn't handle being alone with me, could you?" You see her lip quiver as her brain accepts and rewrites her memory. "And even though you're the nurse, you still defer to me if I have orders. It makes you feel sooooo good when you obey my orders. And today, you've got rounds to do... and I'll be there every step of the way.

"Now clean yourself up, slut (she quivers again) and get me a uniform. We're going to be late!"

You release your grip on her and she hurriedly dresses herself, smoothing her pants and salvaging what makeup remains on her face. "Your uniform got trashed? Yah, you shouldn't use public laundry places these days! They're the worst!". You arch an eyebrow. Apparently she must've subconsciously justified your orders without you even telling her to. That makes things easy.

She scampers out of the door, and you take the time to wash yourself off while she's gone, trying to hit objects from across the room with your gas. By pursing your lips and using a forceful exhale from the diaphragm, your gas can barely hit an object as far as 7 feet away, but not that well. Maybe singing classes could improve it?

Nonetheless, after all this time, you nail down the ability to stop leaking multicolored smoke every time you exhale. It's not something you can really describe... like learning to wiggle an ear. It's just there.

Nicole returns abruptly, her makeup freshly redone, holding a set of sky-blue scrubs and a name tag. Below your name, the title reads "CNA".

You dress yourself and admire your reflection in the mirror, surprised at how well the uniform fits you. She may be your doting ****, but she's also got a hell of a brain for sizes. Maybe that brain's how she became a nurse. It's nice to know you own it now.

Nodding in agreement, you take a clipboard from her and she lead the way out of the room, her ass swaying just barely for you to see.
