Fluttershy was nervous. She had been nervous ever since she realized what the odd and inappropriate gifts, that she received every Advent Sunday from Rarity, would lead up to. And now, on the midnight of Hearth's Warming Eve, she was sitting on her couch, a present box on her lap. Fluttershy had a very good idea what it was, especially since the unicorn was stark naked, but that only excited her more.

“Go ahead, open it, darling,” Rarity said with a naughty smile. “I'm sure you will find it very... sweet.”

After hesitating for a bit, Fluttershy slowly reached out and unwrapped her present. When she opened the lid of the box, her suspicions were confirmed. It was painted with red and white stripes, like a candy cane, but the shape and the fact that there was a hole on the bottom of the box left no doubt: It was Rarity's cock, completely erect as if it was just waiting for her.

“Do you like it?” the unicorn asked. “Pinkie Pie helped me with... the preparations.”

Fluttershy just nodded, her eyes fixed on the hard member. The coloring made it look even tastier than it would have been otherwise. As she looked at it, she felt a tingle between her legs.

Rarity set the box aside, freeing her cock and patted the seat beside her. “Well, then you should take a taste.”

The pegasus got on the couch, kneeling next to Rarity. Looking down at her erection, she couldn't help but lick her lips in anticipation. After some hesitation, she leaned down and licked the tip. Unexpectedly, it tasted pretty sweet. But that fit the coloring well and was probably the reason she had help by Pinkie. After that small taste test, Fluttershy grabbed the base of the cock and took it in her mouth, first just the tip but then sinking lower and lower.

Rarity gasped as the pegasus licked her cock and began to moan softly when she lowered herself on it. She felt her lips engulfing her and her wet tongue moving all over the hard shaft. While she sucked on her, the unicorn grabbed the hem of Fluttershy's sweater and pulled it over her chest, revealing her large breasts that now hang down freely.

“Even in this cold, you're wearing no underwear?” she remarked with a smile. “You're really a naughty filly, Fluttershy...”

She grabbed one of the breasts, squeezing the soft flesh. Her palm brushing over the hard nipple, she caused the pegasus to moan softly, muffled by the cock in her mouth.

Having taken in as much as she could, Fluttershy moved up again, her lips rubbing over the shaft, while her tongue tasted every part. It was very sugary, but not overly sweet. Just enough to make it a delicious treat.

Getting hornier from sucking Rarity's cock and having her breast fondled, Fluttershy slipped a hand into her pants, down between her legs. She rubbed her pussy, moving along the lips, slippery from the wetness, and circling them. The pleasure made her moan and soon she dipped her fingertips between the folds, fingering herself slightly.

Still kneading her breast, Rarity watched the pegasus masturbate, while she sucked her off. The sight aroused her even more and soon made her crave something else. Leaning down to her, she whispered: “Let's go all the way, darling.”

Fluttershy stopped and looked up at her, some saliva running out of her mouth and dripping down at the cock. The coloring was nearly completely gone, revealing the natural gray underneath. She nodded and stood up again, turning around. As she removed her pants, Rarity got a good look at her shapely butt. Reaching out with both hands, she got hold of it, squeezing the soft cheeks, then grabbed her hips and pulled the pegasus towards her.

Guided by Rarity, Fluttershy lowered herself on her lap, until the entrance of her pussy brushed against the tip of the unicorn's cock. Rarity grabbed it, holding it in place, while the tip spread the lips and entered her. Both mares moaned loudly as Rarity's hard cock slowly moved through Fluttershy's wet pussy, until it was fully inside her.

Reaching around, Rarity grabbed Fluttershy's breasts and pulled her back, while she began to move her hips and thrust her cock in and out. The pegasus let out a surprised yelp, but soon relaxed and moved her own hips in unison with her. Steadily, the hard shaft rubbed against the tight walls of the pussy.

While she fucked her, Rarity played around with Fluttershy's breasts, squeezing the large globes and teasing her nipples with the tips of her fingers. Occasionally, she pinched them, making the pegasus cry out in pain and pleasure.

The longer it went on, the more intensive the feeling became. Rarity felt like she was getting tighter, while Fluttershy felt like the cock filled her out more. Their moans too got louder, as the pleasure increased.

“I can't hold it much longer...” Rarity said, continuously thrusting into her.

“J-Just cum... inside me...” Fluttershy replied, riding her with steady pace.

Driven on by that response, Rarity grabbed Fluttershy's hips and increased her speed, nearly pounding into her. It didn't take long until she reached her limit. Coming with a loud moan, she shot many large jets of semen into her.

Fluttershy was very close herself, when the unicorn released her seed into her. Seemingly endless were the streams that filled her body and every one edged her a little closer. Slowly, her belly began to bulge, as her body was straining to contain all the cum. The feeling was getting so intense that it finally drove her over the edge. She cried out in pleasure as she climaxed, just in time for Rarity's stream of cum to end.

Resting for a bit, the two mares stayed like that. “Oh dear,” Rarity said, caressing Fluttershy's enlarged belly. “This will be a mess to clean, when you get up.”

“I-I'm sorry,” Fluttershy replied with a blush.

“Don't be, I made you like that in the first place.”

With that, Rarity pulled the pegasus closer and embraced her. Fluttershy closed her eyes and enjoyed their closeness, not caring about all the things that were still inside her.

“You know how Hearth's Warming Eve is a celebration of all pony races?” Rarity suddenly asked.

“Uh, yeah. Why?” Fluttershy replied.

“Well,” Rarity smiled and caressed her belly again. “Maybe we should invite Applejack next year.”

Author's Note

This was originally the sole chapter, written for Kloudmutt's contest. I wanted to expand it, with one chapter set before (which is "Advent") and one chapter after (which would have been "New Year"). However, I didn't really want to spend too much time on this fic and rather move on and didn't have much motivation, so only the former was realized.
