Placed upon her back, Bon Bon's forelegs and hindlegs were spread and held down by straps. A chill swept throughout the sparse, clinical hospital room, sanitized and sterilized for the work that was underway. Her equine body rose-and-fell with labored breaths, the cold steel of a speculum inserted into her cunt, fully drawn open to expose her.
The moist pink tunnel's walls were connected by strings of vaginal juices that dripped down her canal and over her puckered, hot pink asshole. Her clit was fully swollen, her tail draped over the table, and her feminine musk perfumed the air.
Lyra breathed it in with a flare of her nostrils. Unlike her partner she was human, still maintaining her mint coloration, and her slender but well-shaped supple frame was naked. Erect nipples topped her perky breasts, and a wide grin twisted her face; if she still had a tail it surely would be wagging. Using a tiny mirror with one hand and a pocket flashlight with the other, she gazed into her lover's gaped foal-hole, a hot pink cavern with gooey goodness that dribbled from her dilated cervix.
“This is so undignified,” whined Bon Bon with a roll of her eyes.
“Oh, hush up! I'm about to show you why hands are superior to hooves! Normally a doctor's supposed to wear gloves, but well, I'd rather take the 'hands-on' approach!” She laughed at her terrible pun. With a little Equestrian magic, courtesy of her pal Starlight Glimmer, she'd been able to cross over to that human world and even been allowed to keep that shape on her return!
Bon Bon's ears were pinned against her head, which she turned to one side, her face suffused in a full-on blush. “I'm not sure how you talked me into this. I mean, a human-on-mare? I'm surprised there isn't some kind of law against this!”
“Maybe there will be if we make this a habit!” Lyra set her tools on a gurney to her side and slowly licked her lips from top to bottom. “Now for the real fun to start...”Carefully she placed a couple fingers on Bon Bon's clitoris and traced slow circles around it; and despite how much she'd protested the entire time subdued moans slipped from her snout.
Her marehood winked in rhythmic pulses under her deft touch. She chewed on her lower lip, her eyes watering in joy, and her buttocks clenched with her anus. She writhed reduced to putty under Lyra's mischievous touches, who traced along her puffy, meaty pussy lips, swelled to fullness with blood and slathered in viscous lubrication that ran down her ass cleft.
While she continued to tweak Bon Bon's love button, Lyra used her free hand to slip a couple more fingers into her love's foalhole. She hooked them upwards, traced her spongy g-spot, which caused Bon Bon to arc upwards with a shrill cry as spatters of juices drenched Lyra's arm. “Hee-hee...I think she likes it!” Yet she didn't let up her merciless assault.
“F-fuck....!” Bon Bon continued to thrust her hips at the air, pushed into Lyra's touch, and her shrill screams echoed through their thankfully sound-proofed room. Starlight had set it up to Lyra's specifications to fulfill her fantasy, which Bon Bon had reluctantly agreed to after she repeatedly pestered her. She messily squirted all over Lyra's thin arms with bestial snorts.
“Admit it! Hands are awesome!” She started to withdraw her touch.
Bon Bon pursed her maw and stared into her eyes. “W-wait! I...I was wrong, okay?!”
Leering in a maniacal manner, Lyra redoubled her efforts, thankful she'd been able to get in lots of practice on her lover's human counterpart during her trip over there. She flicked her bean, shoved an entire fist up into her, made her squeal like a banshee when she erupted all over her again-and-again until she reduced her to a crying, quivering, rapturous mess.
Her curls were a frazzled, sweaty mess, and her tongue lolled out. Her dock lashed up her tail and slapped Lyra across the face who giggled. “Knew I'd convince you! Huh, but I'd love to trade places with you sometime, when you're up for it...”
She undid Bon Bon's straps who immediately hopped up and nuzzled her. She returned the gesture with a laugh, holding her, and with a wet pop pulled the speculum free of Bon Bon's gaped cunt which sluiced down her inner thighs. Their tongues met and danced, Bon Bon hooking all her limbs around her companion, body heat shared between them.
Using her earth pony strength Bon Bon pushed back and hurtled them back onto the table. She climbed on top of her, sat her haunches down onto Lyra's face, while her own snout dug its way in Lyra's birth canal. Rapidly wiggling her maw back-and-forth, spatters of love juices spattered her face and shot into her mouth, which she drank down like ambrosia.
Lyra parted her lover's thighs wide as she could and dove in, fingers parting her inflamed folds. She traced circles around Bon Bon's puckered plothole, who treated her to similar service, darting her tongue in-and-out of her soft pink asshole. The pair alternated which orifices they tended to, sucked on pussy lips and pulled on them with their teeth.
“My turn!” Lyra flipped her over so that their positions were reversed.
A loud slap reverberated when Bon Bon struck her love's ass, which quivered and was left with a red hoofmark. She offered similar treatment to the other cheek, determined to take the reigns after Lyra had reduced her to a muddled mess.
Realizing she needed to step up her game, Lyra balled up a fist and shoved its entirety into the slimy foalhole. Her arm slid almost all the way to her elbow, until her knuckles brushed against her cervix. “Umph-!” Bon Bon whinnied and thrashed. Her insides were practically punched while Lyra slammed inwards, and wet splashes sounded while she was drenched.
“Those are some sweet drops indeed,” mused Lyra who licked the mare's honey that glazed her lips. “Ah, I'm close too-!”
Knickers sounded from Bon Bon who cried, “T-together~!” She chewed on her lower lip and squeezed down her holes to a point which made Lyra groan; but she in turn tightened up, and unloaded with her partner in a messy spray. They continuously wailed, dripped over the table, trapped in a climax that seemed to last forever yet was also over far too quickly for the pair.
They disentangled and draped themselves side-by-side. Both panted while they basked in their afterglow, and they interlinked a hand-and-hoof. Both turned to look at the other and shared a giggle.
“So....” Bon Bon sucked in a heavy breath. “Maybe next time I can be the human?”
“We'll see!” Lyra grinned and flicked her nose. While being a mare had its advantages, she almost didn't want to turn back. But she didn't want to freak out the citizens of Ponyville, either; they were always a little slow to accept strange new creatures! Besides, she was also quite eager to see what her companion could do with hands of her own...
