Twilight couldn't help but want to go back up and snuggle down, give a long passionate kiss and make love to Pinkie. Unfortunately for her, Pinkie was already making her way down the stairs with a bit more pep in her step than yesterday.

"Good morning, Twilight!" She called out, jumping the last four steps and landing on her front legs. "It's such a nice day today! Those birds you adopted are sounding really pretty!" She shouted, positively glowing for somepony that had just woken up.

Twilight glared over to her marefriend, unable to comprehend how she can be happy at such a time. "Good morning, Pinkie," she replied, finishing her cereal and levitating it over to the sink. "How are you?"

"I'm fandazitastic, thanks for asking!" Pinkie bounded over to the couch, stopped and sniffed, then backed away slowly saying, "Sorry, Twi... I can't stay if I want to work..."

Twilight sighed and nodded. "I understand. I'll look for something to help you when you get back."

"Okay," Pinkie replied, looking over to the bathroom and rushing over, holding her nose and hoping it would stop the pheromones. "I'll take a quick shower and then head off."

Twilight nodded again and watched as Pinkie closed the door to the bathroom and let out a breath she didn't know she kept. Her entire body was stiff and she melted once the lock clicked. "This is horrible... I can't even hug her..."

Getting up, she walked over to the library’s collection of spell books and started to skin through, looking for anything to help with her heat, at least temporarily. Twilight was so absorbed in finding something that she didn't hear Pinkie leave or the sad goodbye she had called out.

Soon enough, night had set upon Twilight and she was in autopilot mode. She had skimmed through at least a half of the library's books and had found nothing of value. Huffing, she looked around to see the remains of her session strewn around her.

Sizable piles of books were scattered around, threatening to topple over, cups of all shapes and sizes half full with coffee sat in a line from the door and a thin trail of Twilight's fluid spread next to them.

She blushed and looked about, thankful that the library had been closed for the past few days. She gasped as she remembered that she had forgotten to pick Spike up from Rarity's and then relaxed a little as she imagined him running around after her.

Twilight rolled her eyes and decided to ask Pinkie to go out after she came back to pick him up. "It's not like I can go out..." She reasoned, nodding to herself and leaving the downstairs library and entering her apartment.

It was only a mind numbing hour of waiting later and Pinkie hesitantly trotted through the door, looking around. "Twilight!?" she called out, rearranging a saddlebag she was wearing on her back. "I'm coming in now... don't pounce me..." she mumbled, whispering the last half of the sentence.

Closing the door, she spotted Twilight on the balcony to the second floor and beamed. "Heya!" She shouted, happy to see her marefriend.

"H-Hi, Pinkie~" Twilight replied with a predatory look. She seemed to be barely holding herself back and Pinkie looked at her worried.

"I know what's on your mind, but we have to talk..." Pinkie said, moving over to the couch and taking her saddlebag off then unloading the contents out onto the table.

A scroll, some cupcakes and a tube of frosting fell out, clattering onto the wood. Pinkie picked up the scroll she turned around, letting out a yelp as she saw Twilight standing right behind her, a lustful look on her face.

"Hey~" she purred, placing a hoof on Pinkie's cheek. "I'm so horny right now..."

"I c-can can smell it..." Pinkie stammered, Twilight's heat invading her head and making it hard to think. "P-please... we need... to talk..."

"About what~" Twilight asked, leaning forwards and kissing Pinkie's neck, taking her time. Every time her lips would touch the skin, she would nip a little. She loved how it made Pinkie jump. "Come to bed... I'll make you forget about talking..."

"Princess... Luna..." Pinkie just about made out. Twilight hesitated, looking worried and pulled back with a hot flush on her face.

"W-what did she say?" she asked, barely holding herself back from pouncing her mare.

"S-She's happy that we're t-together and has invited us to a p-party..."

"Oh... is that it?" Twilight rolled her eyes and nipped Pinkie's ear, blowing warm air into it.

"W-with everypony..."

Twilight pulled back again, confusion on her face. "Everypony?" she asked, unsure of what she meant. "Everypony everypony?"

Pinkie nodded, a little breathless. "Yep... she's declaring it a public holiday."

Twilight's eyes widened and she looked down shaking. "B-but... I asked the princess to fix it!" She shouted as she started pacing back and forth, her tail twitching, unable to decide on whether she was angry or horny.

"Why... Why would she do this?" she asked, rhetorically, glancing to Pinkie every so often and panting.

Pinkie stared at her, slightly worried, "I never thought I'd say this, but... calm down!"

Twilight looked at Pinkie, confused. "Why would I need to calm down? I'm perfectly fine, never better!" Her mane was frazzled and her eyes bloodshot. "Why wouldn't the Princess do this for me?!" She growled.

"Twilight..."

"Yes?" Twilight snapped, turning to look at Pinkie.

Pinkie leaned forward and pressed her lips to Twilight, closing her eyes at the same time. She let out a small moan as Twilight's pheromones invaded her mind and she let out a small moan that slowly grew in noise.

Twilight shivered and leaned into the kiss, wrapping her hooves around Pinkie's neck and pushing her tongue out, asking for entrance. Pinkie very much obliged and parted her lips, allowing the appendage to slip through to wrestle Pinkie's tongue.

Ever so slowly Twilight backed up and lead Pinkie to the bedroom, almost by instinct as their eyes were shut, enjoying the feeling of each other's lips. They passed through the doorway and Twilight used her magic to close the door, locking it after.

They fell onto the bed, both of them lost in the sea of heat, their minds fogged up as their bodies heated up from the contact and their nerves yearned for each other's touch.

Twilight took the initiative and crawled on top of Pinkie, straddling her and sitting up. She took a deep breath and summoned an ethereal double-ended dildo that simply floated behind them for a second then found its targets.

It prodded their dripping and puffy lips, before started who press in, inching inward and being gobbled up by both of their cunts.

Pinkie let out a moan and gripped the bed so tightly that the sheets were in danger of ripping. She squirmed about, wanting the toy to fill her up faster. Faster I did fill her up, as she squirmed, Twilight felt every movement that happened to the toy, as well as her own pussy being filled, adding to her own pleasure.

"By Luna, YES!" She screamed, falling onto Pinkie. She leaned up and kissed her lover, moaning into her mouth and gripping her poofy hair, pulling it back roughly and sticking her tongue down her throat. "Yes, Pinkie, fuck me!" She grunted, gyrating her hips as the toy bottomed out in both of them.

Pinkie let out a squeak which quickly turned into a moan as her mane was pulled and gripped Twilight's Cutie-mark, squeezing hard.

Twilight panted, her body covered in sweat, her mane slick and stuck to her body. She let out a coo of pleasure as the dildo started to exit her, only leaving the tip inside. She couldn't wait to push it back in, to feel its ridges and bumps grind against her silky walls and fill her no stallion ever could.

She didn't have to wait though as she plunged it back in, both ponies screaming in delight as it filled them both.

"Ah... Ah... Ah..." Twi heaved, thrusting the toy in and out of both of them, her juices flowing freely down her thighs and onto Pinkie, mixing with hers and soaking the bed.

Pinkie groaned as her orgasm neared, she couldn't help it and pulled Twilight down, locking lips with hers as she stiffened, screaming into the kiss. Her body froze as the orgasm raged within. Her eyes rolled up with the pleasure and she laid back, Twilight still going strong.

Although not strong enough it would seem as her own orgasm hit her. Twilight's horn lit up, shooting magic into the air, condensing and raining liquid magic onto the pair. "Ooh~" she let out, falling onto Pinkie Pie as she relaxed.

The pair of them nuzzled each other affectionately and laid there kissing each other until they fell asleep, Twilight's heat gone, but not for long.
