The ancient mahogany doors of the stately library creaked open, revealing a dimly lit sanctuary of knowledge and forbidden pleasures. Agatha Harkness, a 51-year-old widow with a voracious appetite for the taboo, stepped inside, her heels clicking against the polished marble floor. Her trenchcoat hugged her curvaceous figure like a second skin, accentuating every dip and curve.
Rio had been seeing the BDSM mistress named “Witch Tamer” for a while, though their relationship had blossomed into something other than just an exchange of pleasure, and of something of love with now weekly sessions.
Rio looked up from the counter where she was cataloging books. Her heart skipped a beat as she took in Agatha’s appearance. Rio’s own outfit was more modest, a crisp white blouse and a navy-blue pencil skirt, but her eyes smoldered with desire beneath her horn-rimmed glasses.
“Agatha,” Rio breathed, her voice a hushed whisper. “You’re very early. Our next session isn’t until next week”
Agatha smirked, sauntering over to the counter with a sultry sway of her hips. “I couldn’t wait, pet. I’ve been aching for you all week.”
Rio’s cheeks flushed, and she bit her lower lip, tasting the glossy red lipstick. “The library opens in an hour. We have time for a quick… session, If you’re willing?” One thing that Agatha has helped with, was Rio’s confidence.
Agatha’s eyes gleamed with wicked intent. “Oh, I intend to take my time with you, Rio. I want to savor every inch of your delectable body.”
Rio’s breath hitched as Agatha rounded the counter and into the office where the bookbinding would happen occasionally, her movements fluid and predatory. Agatha’s gloved hand reached out, fingers trailing along Rio’s jawline, tilting her chin up to meet her gaze.
“You’ve been a naughty girl, haven’t you, Rio?” Agatha purred, her voice a silken caress. “I can smell your arousal from here.”
Rio whimpered, her thighs clenching together as a rush of heat flooded her core. “Yes, Mistress,” she whispered, her voice trembling with need.
Agatha’s lips curled into a cruel smile. “Good girl. Now, strip for me. I want to see what you’ve been hiding beneath those prim and proper clothes.”
Rio’s fingers fumbled with the buttons of her blouse, her hands shaking with anticipation. She shrugged off the garment, revealing a lacy black bra that barely contained her ample breasts. Her skirt followed, pooling at her feet, leaving her in nothing but a matching thong and thigh-high stockings.
Agatha circled Rio like a predator stalking its prey, her eyes devouring every inch of exposed skin. “Turn around,” she commanded, her voice husky with desire.
Rio complied, presenting her back to Agatha. Agatha’s gloved hands skimmed over Rio’s shoulders, down her spine, coming to rest on the swell of her ass. She gave the supple flesh a sharp smack, relishing the way Rio yelped and jolted forward.
“Such a perfect little ass,” Agatha growled, kneading the reddened skin. “I’m going to enjoy marking it up.”
Rio’s breath came in shallow pants, her nipples hardening into stiff peaks beneath the lace of her bra. “Please, Mistress,” she begged, “I need you.”
Agatha chuckled darkly. “Patience, pet. I’m in charge here, remember?”
She guided Rio to a nearby reading nook, a plush armchair surrounded by towering bookshelves. Agatha pushed Rio down onto the chair, straddling her lap. Rio’s hands instinctively reached for Agatha’s breasts, but Agatha grabbed her wrists, pinning them above her head.
“Ah-ah,” Agatha tsked, shaking her head. “No touching until I say so.”
Rio whined in frustration, her hips bucking up against Agatha’s in a desperate bid for friction. Agatha ground down on her, the linen of her pants now slick with sweat and Rio’s own arousal.
“Feel how wet you’ve made me, Rio?” Agatha purred, her breath hot against Rio’s ear. “You’re such a good little slut for me.”
Rio moaned, her head falling back against the chair as Agatha’s hips continued their tortuous rhythm. Agatha’s free hand roamed Rio’s body, tweaking a nipple through the lace of her bra before sliding lower, fingers dipping beneath the waistband of her thong.
“Mmm, so wet,” Agatha groaned, her fingers parting Rio’s slick folds. “I bet you’d let me do anything to you right now, wouldn’t you?”
“Yes, Mistress,” Rio gasped, her hips thrusting forward to meet Agatha’s probing fingers. “Anything.”
Agatha’s lips curled into a cruel smile. “Good girl.”
She plunged two fingers into Rio’s tight heat, pumping them in and out at a brutal pace. Rio cried out, her walls clenching around Agatha’s fingers as she neared her peak. Agatha could feel Rio’s body tensing, ready to shatter, but she withdrew her fingers at the last moment.
“Ah, ah, ah,” Agatha chided, bringing her slick fingers to Rio’s lips. “You don’t get to come yet, pet.”
Rio’s eyes fluttered shut as she parted her lips, her tongue darting out to taste her own arousal on Agatha’s fingers. Agatha groaned at the sight, her own desire spiraling out of control.
“I need to taste you,” Agatha growled, pulling away from Rio’s mouth. She pushed Rio’s thighs apart, settling between them on her knees. “I’m going to devour this pretty little pussy until you scream.”
Rio’s hands fisted in Agatha’s hair as the older woman’s mouth descended on her, her tongue delving into Rio’s wet folds. Agatha licked and sucked, her lips sealing around Rio’s clit and drawing it into her mouth. Rio bucked against Agatha’s face, her moans echoing through the empty library.
“Mistress, please,” Rio begged, her hips grinding against Agatha’s mouth. “I need to come. Please let me come.”
Agatha pulled back, her chin slick with Rio’s juices. “Come for me, pet,” she commanded, her voice rough with desire. “Come all over my face.”
Rio’s body obeyed, her orgasm crashing over her like a tidal wave. She cried out, her back arching off the chair as her walls spasmed around nothing, her release gushing onto Agatha’s waiting tongue.
Agatha lapped up every drop, her own arousal soaking through the crotch of her underwear. She stood, pulling Rio up with her, and guided her to a nearby table. Agatha bent Rio over the smooth wood, kicking her legs apart.
“I’m going to fuck you now, Rio,” Agatha growled, her hands roaming over Rio’s trembling body. “I’m going to fuck you so hard, you won’t be able to walk straight for a week.”
Rio whimpered, her hips canting back in invitation. Agatha reached into her pants, pulling out a strap-on dildo, and quickly secured it around her hips. She positioned the thick, realistic cock at Rio’s entrance, teasing her with the tip.
“Please, Mistress,” Rio begged, her voice ragged with need. “Fuck me. Fuck me hard.”
Agatha obliged, slamming into Rio with one powerful thrust. Rio screamed, her hands scrabbling for purchase on the table as Agatha set a brutal pace, pounding into her with relentless fervor. The table creaked and groaned beneath them, books tumbling from the shelves with each forceful thrust.
Rio’s second orgasm built quickly, her walls tightening around the thick intrusion. Agatha could feel her own release approaching, her hips stuttering as she chased her pleasure.
“Come with me, pet,” Agatha growled, her fingers finding Rio’s clit and rubbing tight circles. “Come on my cock.”
Rio’s body obeyed, her orgasm crashing over her like a tsunami. She screamed Agatha’s name, her vision whiting out as wave after wave of pleasure washed over her. Agatha followed seconds later, her own release flooding her as she slammed into Rio one final time.
They collapsed together onto the table, Agatha’s body covering Rio’s as they both struggled to catch their breath. Agatha nuzzled into Rio’s neck, pressing soft kisses to the sweat-slicked skin.
“That was… incredible,” Rio panted, her voice hoarse from screaming.
Agatha chuckled, nipping at Rio’s earlobe. “You’re incredible, pet. My perfect little slut.”
Rio preened under the praise, her body still tingling with aftershocks. She turned her head, capturing Agatha’s lips in a deep, passionate kiss.
The library doors creaked open, signaling the arrival of the first patrons. Agatha and Rio quickly disentangled themselves, straightening their clothing and smoothing their hair. As they parted ways, Agatha’s hand lingered on Rio’s lower back, a silent promise of more to come.
Sorry for the slightly out of character for Agatha and Rio..
