Pink gas

You quickly cut off the petite little nurse and exhale a wheezed, high-pitched breath. Nicole's frightened face is enveloped in a blast of pink, and both of you stumble back in confusion.

"NO PLEA-- (koff) I c-c-- (KOFFKOFF) I... (...koff...) ... ... ... hehe."

The gas clears and she is still standing there, holding her head and looking at you with a confused expression. "... What? Heheheh." She covers her mouth in shock, eyes wide with confusion. Why was she laughing? You just stare and watch. "What did yo-- hahahehehehaaaa... (snort)", she giggles, unable to keep a straight face as she backs up a step or two. Her laughter quickly escalates and she stares at you with horrified eyes, but a joyful expression. "HhhhhheeheeheehaaahehehehAAHHHAHAHAHAHAAAA!"

After one long laughing attack, her breathing begins to normalize and she grips both of her sides to calm down. But you realize what the gas does, so you try again by stepping forward and hissing a light-pitched breath. You blast Nicole with the laughing gas once more, and there's no delay this time - her pleading dissolves into hapless giggling and squealing.

"N-NOOOOOeeeeEEEEHEEHEHEHEEEhaaa! AAAEEHaahahHEEEheeheehaaaaa!!", she bellows, falling at your feet and shaking helplessly from your gas. Nicole's face is stretched ear-to-ear in a massive, toothy smile that visualizes what she feels inside - an endless sensation of tingles that combine pleasure with the feeling of feathers all over her body. She can't help but tremble and cry from laughter.

This goes on for about 10 minutes while you just stand there, alternating between little puffs of pink and green gas, reflecting on just how fuckin' weird this is. Nicole just shakes and laughs like a woman possessed, tears leaking from her face.

(At this point you can backtrack to the "Green" option to continue, try a different color, or write your own continuation. You're an adult. Make a decision.)
