Pie Sister Surprise Swap Day (With Rarity)
The Diamond and the Rough
"I want to get Maud a good gift," Rarity said, "but your sister is simply impossible to shop for, dear."
"I've already got you covered!" Pinkie Pie said, giving Rarity a wrapped box with Maud's name on it.
"Oh? What is it?" Rarity asked.
"It's an accessory for her pet," Pinkie said.
"Oh, like the rock pouch from last year?" Rarity asked.
Pinkie shrugged. "Eh, more or less."
"Well, thank goodness! I was worried that I'd be showing up empty-hoofed!"
Returning from the market, the three of them sat together at Rarity's kitchen table. Pinkie gave Rarity her gift. She unwrapped it and looked inside.
"It's a necklace!" Pinkie squealed. Rarity lifted out the 'necklace'. It was a collar. Though it was just like Pinkie to do all of her shopping in one manic stop at a pet store. "Here! Try it on!" Pinkie moved in a flash to put it on Rarity, adjusting it to be snug, without being too tight. It seemed similar to one of those 'choker' necklaces that Sweetie Belle kept mentioning.
"It's, uh..." Rarity smiled. It was the thought that counted. "Thank you Pinkie." Rarity presented the wrapped gift for Maud. "An accessory for your pet."
Maud unwrapped the box and looked inside. Then she looked at Rarity. And then at Pinkie, who was grinning like always. And then back at Rarity. She lifted the leash out of the box.
"Thank you, Rarity."
"Are we ready for our Rarity experience, Darling?" Rarity asked from the bed.
"Almost!" Pinkie Pie said, bounding into the bedroom with her bag of things.
"Ah, and what sort of toys do we have this time?" Rarity asked. "Are we doing that party trick with the beads again?"
Pinkie Pie giggled. "Not exactly." She pulled out a pair of fuzzy hoof cuffs.
"Oh." Rarity looked at them curiously. "This is both more and less interesting than I was expecting."
"That's me!" Pinkie said, climbing onto the bed with her. "Full of surprises!" She cuffed each of Rarity's hooves and fastened them to the headboard of her bedframe. Rarity looked up at her standing over her. Pinkie Pie looked back down at her and smiled. "The safe word is banana." She leaned down and started sucking Rarity's horn.
Rarity purred from the oral stimulation. "Pinkie, darling, appreciate that you've done your homework on the matter. But I don't think a safe word is really necessary. I am a unicorn after all."
Pinkie carefully maneuvered her tongue and then backed off. "Well, you see, about that..."
Pinkie moved out of the way and Rarity could see herself in her vanity mirror. Her eyes crossed as she looked up at her own horn, and the magic inhibition ring on it. A simple attempt to test it confirmed that it was indeed working and firmly snugged in place around the base of her horn. "Oh dear..."
Pinkie grinned. "There's just one more surprise. Don't go anywhere!" she teased as she trotted out of the room.
"Not that I've much of a choice," Rarity breathed at she experimentally pulled at her restraints, finding them to be quite secure. Her heart fluttered in her chest. Was it fear? At it's core it was fear, yes. It was the first time in a long time that she felt genuinely vulnerable.
But she trusted Pinkie Pie. She was a friend who would never actually hurt her. It was like riding a rollercoaster. She was scared but it was tempered by an underlying sense of safety. She was still in control. She had her safe word. She could stop this at any time.
But even the best built rollercoasters have a non-zero chance to fail. Theoretically, Pinkie Pie could ignore the safe word rule and do whatever she wanted to Rarity, and she would be helpless to stop her. She didn't genuinely think that she was going to die. But she couldn't know for sure that she was going to live either. The very thought gripped her with fresh terror. Her heart raced in her chest. And her clitoris winked in aroused excitement.
Steady hoof steps walked back up the hallway towards the bedroom. Carrying a duffle bag on her back, Pinkie Pie was almost unrecognizable under the hooded mask and cape. No. Not a cape. It was a familiar frock. Rarity looked closer and squinted.
"Maud!?"
"Yes."
Rarity snapped her legs together to hide her modesty. "Oh! Uh, this is unexpected!"
"That's Pinkie for you," Maud said. "Full of surprises."
"I take it that she knows you're here?" Rarity asked.
"At her request."
"Yes, well, be that is it may..." Rarity pulled at her restraints. "Why?"
"You have brought her much joy. I wanted to return the favor to you. You don't need to reciprocate," Maud said.
"Oh, heavens, no, it's not that! I-"
"I know," Maud said. "You can't get away from your own generosity. Even to a fault. You give and give without thought for yourself. But deep down, in a place that you bury deep in your heart; what you don't want to admit, even to yourself, is that you want somepony to be just as generous as you, to you. You want, just for once, to not have to always be the responsible one, the one in charge. You want to surrender control and let somepony else take the reins." Maud produced the leash and clipped it onto Rarity's collar. "Your reins."
"Oh, you don't have to do that, darling."
"I understand that I am under no obligation," Maud said. "My choice to do this of my own volition is what gives it value."
"I appreciate that, but what about my volition!?"
Maud looked at Rarity's horn ring and hoof cuffs. "Unless you wish to voice an objection, of the fruit-based variety..?"
Rarity felt her pulse quicken, but she said nothing.
Maud shrugged off the large duffle bag of toys. They hit the floor with a heavy thud as Rarity chewed her lip. "You've been a very good girl. And I'm going to give you what you want. What you deserve. Whether you will admit it or not." Maud held the leash taut and leaned closer to her ear and hissed, "Bitch." Maud used the leash as a lead and pulled Rarity's head to the side and started lightly nibbling on her ear. "I hope you weren't expecting another quickie..."
"M-Maud..."
Maud tugged her leash. "No!" It was the first time that Rarity had ever heard Maud raise her voice slightly. "When I'm holding the leash, it's Mistress. Or Mommy if that's what tickles your nipples. Speaking of..."
She ran her free hoof down along Rarity's belly. She wasn't pregnant or nursing a foal, so she didn't have noticeable teats. Her nipples were little more than a pair of pencil eraser nubs amid the fur of her lower abdomen. They were easy to miss to a less experienced or caring lover. Maud was neither. Her hoof lightly grazed the tips of her nipples but then moved in small circles on them giving no doubt to Rarity that the contact with her erogenous zone was intentional.
Rarity purred and her eyelids flittered. She rubbed her thighs together to self-stimulate her marehood. Maud stopped touching her nipples and tugged the leash to pull her from her daze. She scolded Rarity simply, "No."
Maud climbed off the bed and opened the duffle bag. Rarity strained to crane her neck and see what she was getting. She didn't have to wait long for her to climb back on the bed with what was obviously a spreader bar. She grabbed one of Rarity's legs and fitted the shackle around her ankle. Maud grabbed her other ankle and Rarity tensed. Maud's eyes met hers for just a moment of hesitation.
If Rarity had access to her magic, she would have been able to easily defend herself from such a violation. But without it, her lithe frame was powerless against the ropey muscles of the hard-working earth pony rock farmer. Rarity clenched her jaw and swallowed back the safe word. Maud held Rarity's legs firmly and pried them apart, exposing her wet marehood on full display in the cool open air as Maud shackled her other ankle into the spreader bar.
Rarity flinched at Maud's sudden movement, expecting a full-on assault of her vulnerable sex. But none came. Strangely, in the wake of Rarity's fright came not relief, but disappointment.
"No more rubbing for you," Maud said to Rarity's thighs. "That is my job." She took the free end of the leash and held it at the ready like a whip. Rarity clenched her eyes and braced herself. Maud gave her inner thigh a light slap. It was barely audible, let alone anything even close to painful. Again, much to her confusion, Rarity felt only disappointment where she had expected relief.
Maud moved to her side again to hold her leash in one hoof and the other resuming to play with Rarity's nipples. Rarity squirmed and flexed but only managed to frustrate herself. Maud gave her leash a firm tug, making her movements stop. She nibbled on Rarity's ear again and whispered. "I know you're the kind of mare to get excited. But I promise if you just relax, I won't leave you on the edge for too long."
Maud nibbled her other ear, massaging the edge of it with the muscles of her lips and tongue before moving back to her horn. Even though Maud wasn't a unicorn, herself, she understood just how sensitive the horn was. It wasn't the hasty slobber that Pinkie had managed while she snuck the magic ring on. Maud started lightly, barely-there contact. It was like butterfly kisses with the tip of her tongue, starting at where the edge of the ring stopped, working her way up along the ridges.
"Mau-" Rarity started to moan. Maud stopped in an instant. "...Mauommy. Mommy." Rarity hastily corrected. "Mistress! Please, don't stop!" Maud sat upright and turned her other hoof around. Rarity braced herself for the slap from her disobedient outburst. Maud simply caressed the side of Rarity's cheek with the back of her hoof.
"Of course. I am a generous mistress." Maud said as she leaned forward and resumed licking Rarity's horn. Starting lightly at first again before being... less so. She kissed the tip of her horn and very, very slowly, took it into her mouth. Her tongue took no break, licking the ridges of her horn even more. In her peripheries, Maud could see Rarity's hips bucking, grinding at the empty air. She arched her back to try to get her marehood some friction against the bed sheets.
"You're being very aggressive, Rarity," Maud said. "We can't have that." She went into the duffle bag and grabbed a length of chain, fastening one end to the spreader bar and the other to the bottom of the foot of the bed frame, keeping her body flat against the mattress.
Rarity made a sort of whimpering whine in compliant. Maud was a consummate dominatrix. Rarity wasn't restrained in any way that was creating discomfort. Restricting Rarity's ability to stimulate herself was more of psychological irritant than anything else, forcing her to abide by the surrender of her will.
Maud hovered her free hoof above Rarity's marehood. Rarity tried with what little mobility she had to arch her hips up to touch Maud's hoof. But just as her violet pubic fluff barely grazed Maud's hoof she lifted it just barely out of reach. "Ah..." Maud teased.
"Touch me!" Rarity demanded.
Maud's other hoof took the free end of the leash and patted Rarity's cheek. "Naughty."
"Please touch me!" Rarity corrected.
"Please touch me..?" Maud lead her.
"Please touch me, Mistress!"
"There's a good pet," Maud said. She touched the tip of her hoof against Rarity's side, feeling the contours of her ribs under her fur. "Here?" she asked. Rarity squirmed and tried not to laugh from being tickled.
"N-no!"
"Where?" Maud asked, trying harder to tickle her.
"D-down there!" Rarity said.
"As you wish." Maud moved to the foot of the bed and started touching Rarity's hooves. Rarity bucked and struggled against the restraints, but the shackles kept her hooves in place. Rarity could not quiet her laugh as Maud barely had to try to tickle her hooves.
"No. No!" Rarity squealed between bouts of laughter. Maud relented just enough to let Rarity catch her breath. "Please don't tickle me Mistress!" Maud simply held Rarity's hoof still without tickling her. Rarity panted. "Touch- please touch my flower, Mistress!"
"As you wish." Maud got up from the bed and walked over to the vase on the vanity to hold the stem of one of the tulips. "Is this your fetish, Rarity?"
Rarity huffed in frustration. "You- you know perfectly well what I mean!"
"Do I?"
"I mean for you to touch my intimates!" Rarity said.
Maud opened her dresser drawer and touched a pair of her panties. "How scandalous."
"I should expect this sort of silliness from Pinkie, not you! Must I spell it out to you!?"
"Yes."
"Please! Touch my- my genitals, Mistress!"
Maud almost smirked as she walked towards the bed. "Genitals? I did not realize you were a physician. Are you referring to this?" Maud pointed her hoof closely to Rarity's crotch.
"Yes!" Rarity bucked her hips trying to make any kind of contact.
"You want me you touch your hot, wet, horse..." Maud hissed the word, "pussy?"
"Yes!"
"Say the words."
"Please Mistress, touch my- my pussy!"
Maud smiled the briefest sliver of her teeth. "Soon." Rarity whimpered. "Pick something else first."
Rarity whined a little more and struggled against her bindings. "Nipp- no, horn! Horn again please! Mistress!"
"Well, since you said please..." Maud sat on the bed next to Rarity's head and leaned over to lick her horn again.
Rarity closed her eyes and flexed her hips with what little range she had. Maud understood that in addition to being a conduit for magic, a unicorn's direct connection with her central nervous system made it a sensitive erogenous zone. Her entire body reacted together to the sensual stimulation. This did not escape Maud's notice. She held Rarity's steady head with her hooves.
"Look," Maud commanded between licks of Rarity's horn. Rarity opened her eyes. The way Maud was holding her from off to the side forced her to look at her reflection in the vanity mirror. Rarity's marehood was on full display from the spreader bar keeping her legs wide apart. Maud sucked Rarity's horn, licking the ridges, making her clitoris wink in the mirror. "Look at that horny whorse in the mirror." Such name-calling would have normally hurt Rarity's feelings. But she just moaned and flexed her body, making her pussy wink again harder.
Maud shifted herself slightly, getting her free hoof on Rarity's nipple again, rubbing and gently flicking. Rarity's torso bucked with what little range she had. Her hips desperate to feel a penis that just wasn't there. She shifted her hoof slightly lower. She could just barely reach her pubic tuft while still sucking Rarity's horn. She bucked her hip again, just barely hitting Maud's hoof with with her winking clitoris.
Maud felt her tongue tingle and her mane started to stand up. She pulled her hoof away and stopped sucking to keep Rarity's horngasm from yet going off. Rarity nearly thrashed, she shook for a moment before calming down, once again denied release.
"You're awful!" Rarity growled.
"Tisk," Maud scolded. "Be patient." She shifted down the bed to between Rarity's legs. She held her hoof just in front of her marehood. Rarity stretched and strained her hooves in the shackles to get her vulva to reach Maud's hoof. Maud waited for her to stop before she slowly closed the distance.
She cupped the base of her vulva with her hoof, taking care to intentionally avoid touching her clit. With a mild pressure she rolled her wrist from side to side as though she was gently washing a a cooking pan with a sponge. She leaned closer and sucked at each of Rarity's nipples, licking them as she did, giving them just the lightest of pinches with her teeth. She switched back and forth between them as her hoof kept rubbing her vulva. Rarity flexed and arched her back but Maud was able to easily avoid her tactics.
"Please! Please no more teasing Mistress!" Rarity begged.
Maud sat upright. She lifted her hoof and looked at Rarity's syrupy wetness dripping from it. "Hmm. Maybe you are ready."
"Ready!?" Rarity's voice was rough and haggard. "I am beyond ready!"
Maud smirked. "It's cute that you think that." She climbed off the bed. "Let's see how long that confidence lasts. I know what you want. What you need. I have it in my frock. In fact, it rhymes with frock."
Rarity considered the mare. "It better not be a rock." Maud unfastened her frock and shrugged it off her shoulders. And then Rarity saw it underneath her. One could be forgiven for mistaking it for a stolen bed post. Maud reared up and displayed the massive beast to her.
"Cock."
Rarity would have recoiled if she were physically capable. Not that she had mistaken the strap-on for the real thing, but the sheer size of it alone. Maud stepped closer. Rarity would have snapped her legs together were they not braced apart, leaving her helplessly vulnerable. Maud laid the massive dildo against Rarity's belly, only exaggerating the sheer enormity of it.
"Heavens, NO! My poor lady bits would be ruined! That- that thing would split me in half like a piece of timber!" she shrieked.
"You'll be fine," Maud assured her. "You'll get off for sure. Although..." Maud stepped away for a moment and reached into the duffle bag. She lifted out a large blindfold. "Maybe it's better that you not see this." She put the blindfold on Rarity.
"M-Mistress, wait! I... don't make me say it!" Rarity said.
Maud paused. "You could, I suppose. I suppose I would have to stop. Or..." She trailed off, letting the implication hang in the silence. Rarity's heart raced even faster. Her breathing was rapid and shallow. Her pussy winked and flexed in fresh, confusing arousal. Maud whispered into her ear. "Don't worry. It won't even hurt."
Maud silently grabbed another toy out of the duffle bag and then positioned herself between Rarity's spread legs. She heaved the massive dildo onto her belly again with a heavy thwack.
Rarity whimpered but waited. If it hurt even a little she was going to scream the safe word and Celestia help Maud if she didn't respect it.
Maud shifted her hips back and silently unbuckled the ridiculously-large strap-on, setting it on the floor. The other toy in her hoof was a simple design. Barely thicker than a broom handle no longer than a flashlight, it looked more like a modest cucumber than anything else, with a slightly-thicker bulb at the end with a bit of upward curvature.
"Ready? Here it comes." She touched the tip of it to Rarity's marehood and she shuddered, expecting the worst. Her copious wetness and the modest size of the toy let it slip inside easily. Still blindfolded, Rarity could feel it sliding inside her, but to her imagination, it was still that monstrous strap-on. "Wow. Look at you just swallow this thing up. I knew I picked the perfect size for you. You make it look easy." Rarity was prepared for visceral pain. But somehow, this outcome was even worse.
Maud worked the small toy in and out of Rarity's pussy, using the curved bulb to focus on that soft, spongey spot just a few inches inside. Back and forth across that spot. In and out. She angled her wrist to really point it upward and hit it while her other hoof applied a light pressure to Rarity's lower abdomen.
Rarity's panic of expecting pain subsided, and her fear of Maud's empty implication passed. The endorphins were still flooding her system, amplifying her pleasure even more. She felt almost light-headed from the euphoria. But behind all of that, she started to feel a strange, yet familiar sensation growing. Part of it was her growing orgasm, but more than that was something more urgent.
"Mistress, I- I hate to interrupt, but- I think I need a potty break."
Maud knew better. "Denied. All you've done is complain and make demands."
"I know I've been a very naughty filly, but I really need to-" Rarity's voice hitched in her throat as Maud suddenly quickened her pace. Behind the blindfold, Rarity saw stars. All the wires in her brain crossed and misfired. Any words she tried to form dribbled out of her mouth as a jumbled mess of guttural vowels. Somewhere in her brain, she could register the growing pressure in her lower abdomen. If there were anything left of her conscious mind, it would have felt embarrassment of a little filly for what was about to happen.
Maud's hoof holding the toy was a blur. The ring on Rarity's horn glowed brighter and brighter. Her she inhaled sharply. Maud's free hoof reached up and grabbed Rarity's blindfold, pulling it off her head at the last moment. Rarity barely had a second for her eyes to adjust to the light before Maud pressed the button on the base of the toy, turning on the vibrator and in the same motion, she released the toy. Maud's hoof played with Rarity's clit like a DragonForce guitar solo.
Rarity's back arched and her hips bucked, all but levitating off the mattress as she came hard. Her strong pelvic muscles ejected the small toy out of her vagina like a champagne cork, ricocheting off the mirror, followed by a powerful jet of marecum. Not just once, but repeatedly, again and again as she bucked her hips against Maud's hoof still playing with her clit. She splashed and blurred her mirror reflection with mouth gaped in a silent wail.
When at last she had gone dry her hips collapsed onto the mattress and Maud removed her hoof instantly. Rarity's entire body quivered and trembled as the aftershocks of her orgasm continued to rumble through her. Maud worked quickly to undo the shackles on Rarity's legs and hooves, letting her finally relax her limbs. But rather than snapping her thighs closed like Maud expected, she just left them splayed apart.
Rarity's eyes crossed as she looked up at Maud taking the ring off her horn, freeing her at last from the final restrain.
"Oh, goodness! I fear that I may have cum so hard that I may have had an accident!" She looked at Maud's dripping mane. "And it looks like you were caught in the splash zone, as it were." Rarity covered her face in embarrassment. "I'm so sorry!"
Maud climbed on top of Rarity and pulled her hooves away from her face. "There is nothing to apologize for. Have you never had a squirting orgasm before?"
"I beg your pardon? A what now?"
"Squirting. It's not pee. Some mares do it when they cum really hard. How was it?"
Rarity looked at the mess she had made. Embarrassed as she was, she couldn't deny the truth.
"Darling, it was simply divine! I have never ever climaxed so hard before in my life!"
Maud bit her lip and trembled. Her entire body practically vibrated. A few droplets of her arousal dripped onto Rarity's belly. "Same."
"What? Just now? But I didn't even touch you!"
Maud smiled. She really smiled. "That's my secret Rarity. Getting you to cum gets me to cum." She leaned closer and kissed Rarity. "This was the best threesome ever."
"Threesome!?"
Maud squatted over Rarity's belly and squeezed Boulder out of her vagina.
