They tug on the redhead's ear and she drops. Her eyes roll back, her head slumps to the side, and her knees begin to buckle.

They already have their arm around her waist and a palm at her cheek as it happens. You hear them coo, "Good girl, just sink automatically. Here you can just kneel down and rest." 

The redhead slips down onto her knees, guided by their arms, coming to rest with her face against their tummy, her head cradled in their arm. 

You realize you're staring openly at the pair, a very visible blush across your cheeks. To be fair, the three of you were having a conversation. 

While trying to mingle at a friend of a friend’s party, you gravitated towards the visibly queer couple in the corner, a redheaded femme and her dark-featured partner. You managed to strike up an easy, if unexciting, conversation, when they offhandedly mentioned hypnokink. You asked what they meant, trying not to sound too ecstatic. Apparently, the redhead’s partner decided to demonstrate.

"See it's easy," they say, "especially with such a talented subject who’s doing such a good job for me," they continue, speaking now to the redhead in a babying voice, as they run their fingers through her hair. 

Your blush deepens as the redhead lets out a high moan, and you feel your heart pound. You’re in a packed living room. The hum of music, press of people, and buzz of conversations provide some degree of privacy, but not enough to make a girl moaning on her knees inconspicuous. Yet, no one around you seems to have taken notice. 

They smile, their eyes boring into you. “Would you like me to stop? I don’t want to make you uncomfortable.”

“No!” you blurt out a little too forcefully. “I mean. I’m curious. I just… there are a lot of people around.” 

Their smile widens mischievously, “Let them worry about themselves. I don’t think it’ll be a problem, though.” They wink. “So, what are you curious about?” 

“Well,” you hesitate wondering how much to share, “what does it feel like?” you ask, struggling to maintain eye contact with them. 

“Go on,” they ruffle the redhead’s hair, “what does it feel like?”

“Sooo goood,” she whines, her voice catching in high desperate peaks. 

“I’m afraid that’s probably as much detail as you’re likely to get from her in this state, though,” they chuckle. Leaning down towards the redhead they coo, “What a good girl,” eliciting another high moan. “When she’s more cogent, though, she describes it as a warm tingly feeling that spreads across her body.” They continue to lean over the redhead, their voice low and confident as they describe the sensations. They’re clearly speaking to their partner, but making intermittent eye contact with you, smiling invitingly. “Her thoughts start to get looser and more difficult to hold on to as the sensation of gently floating away sets in. Sometimes she feels an intense, warm tingle from her neck down her spine.” They trace a finger along her neck and she spasms in response. “It’s very pleasurable.” 

By now the redhead is blushing more than you. Her mouth is parted gently, and you can hear her breathing heavily–panting. She seems totally unaware of you or anyone else. Your stomach flips and churns with–you’re not sure–some not unpleasant emotion.

“Can I ask you a question?” they say, and you notice the sharp difference in their timber and pitch. They are once again casual, conversational, although their mischievous grin has only widened.

“Yeah,” you manage. 

“Why are you so curious?” they say staring you down. 

You choke up. Stammer. Try to keep your eyes from flitting away. 

The redhead lets out a high moan, interrupting the moment. 

They look down and coo, “Awww, poor pet. You must be so worked up. It’s ok you can rub yourself against my leg just a little. You’re being such a good girl for me.” 

Your stomach flips again and you gasp involuntarily as you see the redhead begin to grind her hips gently against their leg.

“No answer for me?” they ask, returning their gaze to you. 

And then you identify that not unpleasant emotion: envy. “Because I want it,” you manage.
