Day 7: Strap-on

Summary:

“That’s yummy, what is it?” she asked, once she had swallowed.

Shadowheart turned around and surveyed the half-empty vial in her friend’s hand. Her heart sank.

“That was full when I gave it to you.”

“Yeah

“Oh no.”

“Oh no what, Shads?”

Shadowheart clapped her hands to her face. “I thought you knew you’re only supposed to take a tiny sip at a time.”

Nocturne was beginning to panic. She could feel her pulse climbing and her neck heating. Her heart was loud in her ears.

“Shadowheart, what did you give me?!”

Shadowheart sighed. “It’s an aphrodisiac potion. Just a sip helps me relax—it loosens me up much faster than alcohol.”

It was then Nocturne realized the thrumming pulse and the heat spreading across her body wasn’t panic—it was arousal. She grabbed one of the decorative pillows from Shadowheart’s bed and positioned it across her lap.

Notes:

Slowly getting caught up by dipping my toe into the rare pair pond. Here is day 7! The prompt strap-on came from @thatonefanaticinclass's Kinktober 2025 list. If you see this, thank you!

I actually started writing this for different Kinktober prompt last year and never finished it. Thank you also to my past self for the lift!

Happy reading!

Day 7: Strap-on

“I’m so excited you’re finally coming out tonight,” Shadowheart said. She spread a large array of tubes across her bed—long transparent ones filled with colorful glosses mixed amongst plastic and metal bullet-shaped ones. “Now, pick a color.”

Nocturne picked up one tube at a time, popping each cap off, twisting it to reveal just enough of each perfectly pointed product to examine the color, then back down into the casing before snapping the lid back down.

“You’re sure this is a good idea?” she asked.

“Of course it’s a good idea,” Shadowheart insisted. “You need to let off some steam and so do I. Work’s been an absolute nightmare this week; Vic is such a hardass. We’ll find a couple of dumb boys to buy us drinks and dance the night away together. Come on! It’ll be fun!”

Shadowheart was right about one thing, at least. Nocturne desperately needed to blow off some steam. It was her second to last semester of undergrad and she’d nearly been crushed under the weight of the many papers she’d had to write for midterms. She wasn’t much of a partier, ordinarily preferring one of the quiet research libraries on campus or the cozy sanctuary of her own small, lofted bedroom in the apartment she shared with a few other girls from her program. As her oldest friend, Shadowheart knew this, but that didn’t stop her from begging Nocturne to accompany her bar hopping almost every weekend.

“I know what you need,” Shadowheart said. She opened the bottom drawer of her nightstand. Nocturne tried hard not to stare at the perfect curve of her friend’s ass in the tight ribbed dress she wore as she bent over. Out of the drawer, Shadowheart pulled a round potion vial full of shimmery violet liquid. She handed it to Nocturne.

“Here. Liquid courage. Look how cute, it matches your hair.”

Nocturne uncorked the vial as Shadowheart turned back to the mirror to apply a second coat of mascara. She lifted it to her nose and sniffed. It smelled of freshly sliced strawberries. She brought it to her lips and took a deep pull, then held the sweet liquid in her mouth for a moment, letting the tiny bubbles fizz and pop across her tongue.

“That’s yummy, what is it?” she asked, once she had swallowed.

Shadowheart turned around and surveyed the half-empty vial in her friend’s hand. Her heart sank.

“That was full when I gave it to you.”

“Yeah, and?”

“Oh no.”

“Oh no what, Shads?”

Shadowheart clapped her hands to her face. “I thought you knew you’re only supposed to take a tiny sip at a time.”

Nocturne was beginning to panic. She could feel her pulse climbing and her neck heating. Her heart was loud in her ears.

“Shadowheart, what did you give me?!”

Shadowheart sighed. “It’s an aphrodisiac potion. Just a sip helps me relax—it loosens me up much faster than alcohol.”

It was then Nocturne realized the thrumming pulse and the heat spreading across her body wasn’t panic—it was arousal. She grabbed one of the decorative pillows from Shadowheart’s bed and positioned it across her lap.

“Shads, I can’t go out like this,” Nocturne said. “Just…give me some time to cool off and I’ll head home.”

“Don’t be silly,” Shadowheart said. She took the vial from Nocturne’s hand, uncorked it, and downed the remaining liquid in a single swallow. “I just need a moment to catch up.”

Nocturne gaped at her friend. The potion was working; she could feel a tightening in her groin and what seemed like too much saliva collecting in her mouth. She swallowed hard.

“Shads, don’t be crazy.”

“Listen to me,” Shadowheart said, her voice lower and huskier than before. Her own body was beginning to respond to the effects of the potion. “I know you’re going to think this is the potion talking, but I’ve wanted to do this for a really, really long time.”

She knelt on her bed in front of Nocturne and cupped her face in her hands, skimming her thumbs over the ridges along her cheekbones before pulling her in for a deep, lingering kiss. Only a few breathless seconds passed after Shadowheart pulled away before Nocturne was chasing her mouth for another. Her teeth crashed into Shadowheart’s lower lip, drawing a bit of blood, but she didn’t seem to mind.

Nocturne’s hands found Shadowheart’s long, dark tresses—the hair I learned to braid when mine was nowhere near long enough, she thought. She weaved her fingers through, grabbing fistfuls of it as Shadowheart’s hands moved to the base of Nocturne’s horns. Shadowheart broke their kiss.

“Is this all right?” she asked, panting and stroking up the curved length of one of Nocturne’s horns.

“Yes, gods, yes.”

Shadowheart spread her legs wider apart, straddling one of Nocturne’s. She leaned forward and pinned her to the mass of pillows on her bed, grinding on her thigh and kissing down her perfumed neck. Shadowheart had always loved the way Nocturne smelled of amber and vanilla and something floral, which she thought she recognized as tuberose now that her nose was buried into the pulse point on her throat. Her kisses pulled a ragged sound from Nocturne’s chest that captured Shadowheart’s heart in a vice. She wanted to hear it like a song on repeat.

A tremor in her hand was nearly all that was left of Nocturne’s inhibition. She needed to touch and be touched. Her open palm skidded along Shadowheart’s side, dipping along all the soft curves that she’d long coveted out of both envy and desire. Never did she think she’d actually get to touch them in this way. Shadowheart’s tight, black dress was hiked up to her hips and Nocturne could feel the damp heat radiating from her core as she pressed and dragged herself along her thigh. The layers between them were comically thin—just two layers of tights and Shadowheart’s cotton panties separated them.

Nocturne was hard. Under any other circumstances—and if she wasn’t enjoying this so damn much—she would have been mortified to be this hard in Shadowheart’s bed. The clutch of the throw pillow against her crotch was enough to have her leaking and smearing all over the inside of her own underwear. So when Shadowheart snaked a hand under the pillow and began pawing at her length, Nocturne feared she might explode. Her spine straightened immediately and she dug her fingers into the softness at Shadowheart's hip much harder than she’d intended.

“Sorry,” Shadowheart cooed as she lifted her and sat back on her heels. “I didn’t mean to make you uncomfortable.”

“You didn’t!” Nocturne said. The words rushed out, partly to assure Shadowheart that she hadn’t done anything wrong, and partly so they could get back to what they were doing—and quickly. “It felt good. Really, really good. Too good, actually. And…I want this to last.”

Shadowheart smiled. “Me too.”

Reluctantly, Shadowheart climbed off of Nocturne and stood at the bed side. Slowly, and with some amount of showmanship, she pulled the skirt of her dress up even higher so that it bunched around her waist. One hand slipped between her skin and the unforgiving lycra of her tights, then lower until three fingertips rested under the waistband of her underwear. She rolled her head back, exposing the column of her throat. Nocturne admired the length of it, her pale skin in stark contrast to her dark hair. Shadowheart’s fingers dipped lower, two between her lower lips. She moaned at the relief of her own touch. Nocturne could hear how wet she was. She watched, enchanted, as Shadowheart rubbed quick, protracted circles around her clit and tried to memorize what the outline of her hand looked like as it moved beneath her tights. Shadowheart ran her other hand through her long, wild tresses and she panted and teetered closer and closer to the edge.

Just as Nocturne thought Shadowheart was about to bring herself to climax, she withdrew her hand from between her thighs and raised her glistening fingers to her mouth.

“Let me.”

The words were out of Nocturne’s mouth before she could even consider them. She brought her fingers to Shadowheart’s elbow and eased her forearm down towards her. Shadowheart aided by pressing her wet fingers to Nocturne’s lips. Hungrily, Nocturne opened her mouth and licked each one gently before sucking all three into her mouth. Her taste was sweeter than she’d imagined—warm and primal and faintly metallic. They groaned in tandem.

Shadowheart took her fingers from Nocturne’s mouth, stroking her thumb along her lower lip a few times before she returned to undressing. Slowly, sensually, she peeled off her tights, leaving them in a pool on the floor. She tugged the snug dress higher, up over her breasts and shoulders and finally her head. Nocturne marveled at her friend’s round, pert breasts the soft, enticing cushion of her belly, the way the band of her black thong hugged her full, feminine hips.

“In my wildest dreams, I never imagined I’d be lucky enough to witness a Shadowheart striptease,” Nocturne said, half-joking and half in genuine awe.

“Dream of me often, sweet thing?” Shadowheart purred.

“Yes,” Nocturne admitted. There it was. The truth finally laid as bare as the glorious woman before her.

“Good,” Shadowheart whispered.

Shadowheart opened her nightstand drawer again—the one that had stored the potion that had derailed their entire evening in the most delicious way—and pulled out a striking leather harness. She held it up to Nocturne.

“Will you let me fuck you?”

Nocturne bit her lip. She wanted to—badly. The potion was working wonders in terms of keeping her hard and horny and desperate for touch, but that didn’t change the fact that she was still new to penetration. She’d experimented enough with the small, silicone plugs Shadowheart had helped her pick out to know that she liked the feeling of her hole being stretched. Liked it a lot, actually. Shadowheart must’ve seen the trepidation flash across her face, because she dug around in the draw again and pulled out the biggest bottle of lube Nocturne had ever seen outside of sex toy shop, along with two thin dildos, one slightly shorter than the other.

“We’ll start slow, and we’ll use as much of this as you want,” Shadowheart said, shaking the bottle of lube.

The truth was that Nocturne wanted nothing more than for her first real time to be with Shadowheart. She had the knowledge, the toys, the experience to make Nocturne more than jus comfortable. What more could she ask for than to be in the care of someone she trusted—someone who loved her?

“Yes.”

Excitedly, Shadowheart bounced on the balls of her feet a few times, and Nocturne’s brain went white at the sight of her jiggling breasts in front of her.

They each took a few moments to prepare—Nocturne disrobing and letting her clothes mingle on the floor with Shadowheart’s, and Shadowheart removing her thoroughly soaked panties and fastening the harness low across her hips. She centered the smaller of the two dildos into the holster and waited patiently for Nocturne to get into a comfortable position on all fours.

Seeing Shadowheart with a dick—silicone and bright blue though it may have been—was almost too much for Nocturne to handle. Her mouth watered as she grasped the toy firmly in one hand.

“Just when I thought you couldn’t get any more beautiful,” she smiled. Shadowheart grinned back and kissed her once turning her around by the shoulders to face the bed.

“On your hands and knees, sweet thing.”

Nocturne did as she was told and heard the soft, plastic click of the lube opening. Both girls giggled at the lewd, reverberating sound the slippery substance made as Shadowheart squeezed a dollop of it into her hand. She warmed it between her fingers, then ever-so-gently used her opposite hand to part Nocturne’s cheeks, just below the base of her tail.

“Ready?”

“Ffffffuck yes.”

Nocturne felt the press of Shadowheart’s coated fingers at her entrance and tried to relax. Her nerves were on fire, her painfully hard cock dripped onto Shadowheart’s bedspread. She’d worry about it later. Shadowheart’s fingers pushed past the warm, tight ring of muscle—once, twice—and then she was fingering her and exploring slowly. Nocturne cried out in pleasure, backing her hips into Shadowheart’s hand, silently begging for more. She couldn’t control the swish of her tail, the tip of which twitched high over Shadowheart’s head.

“The strap, Shads. Please. I’m ready.”

Nocturne heard the bottle of lube open again and Shadowheart coated the dildo in viscous fluid, She knelt on the bed behind Nocturne and nudged her way between her ass cheeks with the cold, slick tip of the toy.

“Breathe in…” Shadowheart said.

Nocturne did.

“…and out.”

Shadowheart gave the first slow, confident thrust as she watched Nocturne’s ribcage contract. Nocturne greedily took half of the strap before a long groan tumbled out of her. Gently, slowly, Shadowheart slid deeper inside until the harness made contact with Nocturne’s flesh.

“It’s in, sweet girl,” she said. “Are you okay?”

There was no verbal response befitting exactly how okay it was. Nocturne drew her hips forward and then sank back into Shadowheart, fucking herself along the strap. She’d never felt so full and she wouldn’t soon forget it.

“Oh, eager, are we?” Shadowheart asked playfully.

“More, Shadowheart, please. Harder.”

Shadowheart reared back and sank faster and deeper into Nocturne, causing the metallic hoops on the harness to clatter and jingle. Nocturne’s moans were high and loud as her full, curvaceous ass slapped against Shadowheart’s hips. Before she knew it, Nocturne was dragging her own length along Shadowheart’s soft, satiny purple comforter. It would certainly need to be washed now.

Nocturne felt her orgasm building low in her belly. Her vision was going white at the edges and she grasped great fistfuls of the fabric beneath her, rocking hard against the strap. She whimpered and whined as she came, gasping down big gulps of air as tears pricked the outer corners of her eyes.

A warm hand rubbed comforting circles above her tail.

“Did you like that, sweet thing? You did so good, my beautiful girl.”

Suddenly, Nocturne understood all the fuss.

Later, after they’d cleaned up and exchanged Shadowheart’s ruined comforter for a soft cozy blanket, they snuggled together, kissing, giggling, and kissing some more. Nocturne laid boneless and blissed out in Shadowheart’s arms.

“So…how long is that potion supposed to last?” she asked.

Shadowheart kissed the top of head, between her horns.

“Hmm…with the amount we took? Probably several hours. Maybe until morning. Why?”

Nocturne’s fingers traced circles along Shadowheart’s hip, along her thigh, slowly making their way to the valley between her legs.

“No reason,” she grinned.
