Concept: a bratty sub whispering “my heart is beating so fast right now” into their dom’s ear in public.
Just think of all the possible responses…
1) A firm grasp of the sub’s wrist whilst they sink their thumb into their radial pulse. “Behave,” the dom quietly growls as the two of them lock eyes. The sub’s pulse immediately picks up its pace, resulting in a chuckle of amusement from the dom, their eyes glistening with admiration. Their sweet sub is just too easy to fluster. “I swear you look even prettier when I know your heart is racing for me,” the dom says, smirking, “now keep that pretty mouth shut about heart stuff until we’re back, will you?”
2) A threat of “I’ll make it beat even faster when we’re home if you’re good for me,” and a smirk at how the sub blushes. The sub opens their mouth, desperate to share how their heart just skipped a beat at the mere suggestion, but quickly shuts it, their needy heart too desperate for attention later to misbehave. “Goooood,” the dom purrs, “but I haven’t finished getting my revenge. You up for the challenge of me teasing you until we get back? The second you make a snarky comment, the most you’re allowed to do is listen to my heartbeat whilst only I touch myself.”
3) A laugh and bear hug attack, the dom pressing their body tightly the sub’s. The dom leans in towards the sub’s ear, purposely grazing their lips up their carotid. “You feel that, baby? Mine too.” The dom whispers, tapping the rhythm of their own heartbeat against the sub’s back.
4) The sub doesn’t even get a chance to turn away before the dom places their hands on the sub’s cheeks. As the dom leans in for a kiss, they slowly move their hands down, their thumbs settling over the sub’s carotids. “I can feel it,” the dom breathes, their breath hot and desperate against the sub’s lips, “I need to feel how fast it beats for me. Kiss me?”
5) The dom pulls up the sub’s sleeve and tuts at the BPM displayed on their watch, shaking their head with a fond smile. “You call 84BPM fast? That’s cute. Run up the rest of the path and back for me and I’ll reassess.” The sub swallows, looks around to make sure that they won’t have to explain themselves to anyone, and obeys. The dom has a shit-eating grin on their face as the sub returns, panting. “112,” the dom hums, satisfied, “that’s much better.”
