Pinkie needed some time off, so her sister Maud offered to fill in for her at Sugar Cube Corner. She didn't expect it to be difficult, but the recently divorced Miss Swirl’s initial kindness turned out to be more that it appeared.
In the afternoon of the second day Maud was called back to the kitchen while trying to assist a customer, and not for the first time. She found the boss whipping up some buttercream, holding out a spoonful for Maud to taste.
Maud allowed the portly pony to feed her. The buttercream was delicious, as always, and this time there was a hint of rock-salt which reminded Maud of home.
Miss Swirl slid the spoon out delicately, holding the end with her teeth and looking at Maud with eyes half-lidded, which made the stoic Pie-sister blush in spite of her bored expression.
"Thank you, dear." said Chiffon with a soft smile. "What did you think?"
Maud swallowed the last of the cream. "Good." she said calmly. She meant it, too. Though the cake lady made her uncomfortable at times she was very good at what she did. Besides, Maud thought she seemed lonely, which was something Maud understood fairly well. After all, stallions didn’t tend to stick around long, mistaking her lack of expression for lack of interest. At least Miss Swirl wasn’t put off by her, and that made her feel good.
As the last light of day slanted in through the windows Maud bid a monotone farewell to the final customer before closing up. When she was done she sought out Miss Swirl to let her know she had finished.
When she couldn't find her in the kitchen she checked the freezer to discover her sat on her rump and eating vanilla ice-cream from a tub held in her hooves.
"Oh, goodness! I didn't notice you there.” she said when she came up for air. “Sorry you had to see me in such a state." It looked as though she had been crying.
Maud approached without a word, placing her hoof on the pudgy mare's shoulder. She was freezing, and Maud wondered just how long she had been in there.
"What are you..." Miss Swirl began, but was unable to finish, for Maud leaned in and kissed her. It was a long kiss that sent shivers down both their spines even as it warmed their frigid bodies.
When Maud pulled away a string of saliva connected their lips afterward, until Maud wiped her mouth with her hoof. The taste of vanilla lingered for a bit on Maud's tongue.
"Turn around." said Miss Swirl after a moment, her hot breath misting in the freezer air.
Maud obliged, as though merely following her boss's instruction.
Chiffon slid the tub of ice-cream between Maud's legs, underneath her straight-cut tail which she brushed aside to get a look at the delicate parts behind. She then instructed Maud to hold in her mouth, which she did, ensuring unrestricted access to her pudenda.
Maud barely had time to wonder what she had gotten herself into before Miss Swirl, (formerly Mrs. Cup Cake,) pressed her tongue up against the grey mare's chilly pussy, her snout pushing against the tight little button of her anus. Maud shivered, but stood still. Her face was turning red, but her expression was still neutral. It was just her nature.
Chiffon licked her pussy from bottom to top, tickling the space between her slit and anus with light jabs of her tongue. She then stepped back and watched Maud's pussy wink, dripping juice into the tub of ice-cream below. Miss Swirl looked around and found a box of popsicles, grabbing one in her teeth as she did the spoon and using the icy tip to tease Maud's anus, though try as she might she couldn't quite get it inside.
This pony could make diamonds in there.
She aimed a bit lower and plunged the frozen spear straight into Maud's steaming pussy as far as it would go, satisfied by the sudden gasp from the rock farmer's other end.
She withdrew the popsicle and set it aside, then placed both hooves on Maud's butt and spread it apart, watching the flesh of her pussy stretch and shift. She pulled them together again and was pleased when a pulse of pussy-fluid was squeezed out, falling once more into the tub of ice-cream.
Miss Swirl thought about eating it herself, then decided to press her luck. "Turn around again, hun." she said to Maud, and Maud obeyed. "Eat."
The Pie-sister looked down at the tub of ice-cream coated in her glittery fluid. For a moment Chiffon wasn't sure she would do it, but she did, lowering her head and lapping up the mixture as though it were a bucket of oats.
Miss Swirl sat back again and began stirring her own pussy with her hoof, focusing intently on the image of Maud consuming her own fluids.
When at last Maud looked up, licking the remaining ice-cream from her lips Chiffon came, squirting Maud in the face and making her wince.
"Sorry dear." managed Miss Swirl between breaths. "Let me make it up to you."
She spun Maud around again after cleaning her face with her tongue, then went to work on Maud's pussy. She dug deep with her tongue, massaging the mare's ass-cheeks as she did.
Maud's tongue lolled from her mouth and she slid down to her elbows as Chiffon pressed into her behind, savagely making love to her sex with her practiced tongue. Maud let out another gasp and a drawn out moan, then fell to the floor as Miss Swirl pulled away.
Lying flat on her belly, legs apart, Maud's twitching pussy pumped fluid onto the floor.
Miss Swirl sat back and admired her work, breathing heavily herself. Though it was tiring, she felt invigorated. It had been some time since she last felt like this, and was grateful to Maud for her part in all of it.
