Dusk landed on Twilight. He felt her hot breath leaving her lungs, but it didn’t stop him from plunging his tongue into her mouth. She wrapped her hind legs around his waist and it drove him wild. He started thrusting. His cock had become erect while Twilight had been reading from the book. Now it was pressed between his body and her belly. He was humping anyway. He was too excited to help himself. His hips worked instinctively, primitive desires overwhelming him.

If anything, Twilight was far more excited. All this time of trying to suppress her desires only made her want it more once she finally accepted it. It was like opening up flood gates. She could feel his long hard cock pressing into her belly, hot even through her coat. His loaded balls were pressed up against her wet, hungry pussy. She could feel each ball rubbing up against her clit. She was grabbing and pulling at his mane. She forced his tongue back into his own mouth and kept pushing it back. She was loving every second of this, but she wanted him more deeply. She wanted him inside of her.

She started to push on his chest, backing him up. She didn’t want to break the kiss, so she strained her neck up until their lips were forced apart. She got up out from underneath him. She was going to turn around. She wanted to “spontaneously raise her hindquarters” for him, as the book so eloquently put it, so he could mount her. She peered into his deep, dark, bottomless eyes. There was so much about love that books just couldn’t say. Even the shameless, unexpected, carnal kind of love she was experiencing right now.

“Fuck it,” she whispered. She reared up, and placed two hooves on his shoulders and pushed. He stepped backwards and into the table. She pushed him so hard he fell over backwards on top of it. More books fell to the floor with a crash. His four legs stuck up in the air. Twilight looked down at him. She took in the sight of his rigid manhood. Bare skin lying on his purple coat, pink mottled with black. His hefty black balls dangled beneath. She hefted it up, gazing at it, so that it was pointing at the ceiling, then she stuck it in her watering mouth.

Dusk’s face was twisted, contorted. If looking at it by itself, someone might think he was in intense pain and unimaginably afraid, when really he was experiencing the most amazing sensation he had ever felt. His front hooves automatically closed around Twilight’s horn as it bobbed, her face moving up and down his shaft. Twilight’s response to just the touch of his hooves was electric. She sucked him down faster and deeper. When he actually started to rub the length of it, she swallowed the whole thing.

Little white-hot sparks were occasionally shooting from the tip of Twilight’s horn. A few were leaping from the tip of his own. That had never happened to him before without direct stimulation. Now, just the sight of Twilight’s lips slipping down his cock, and her horn between his hooves was enough to set him off. The facts that he had just met her, and that they could be discovered at any minute did nothing to diminish his excitement. He tried to focus on the sensation of it, hoping he would be able to remember when they were through. Her mouth was warm and wet, he could feel her moving tongue on the underside of his shaft. Her lips were soft but stretched tight. When she opened her eyes and looked up into his face, he gasped and almost came in her mouth. He gritted his teeth and tried to hold it back. Dusk watched her slide all the way back up, her eyes never leaving his. He watched her lips pucker outwards as she slowly drew the head out of her mouth. It flopped down onto his stomach and she smiled at him. It was the single greatest smile he had ever seen.

Before she could speak, he sat up and kissed her on those lips. She started to back up, and he leaned forward with her. He fell off the table and onto his four hooves. They started to turn around each other, lips still locked. When they got a quarter of the way through the turn, their kiss broke, Twilight turned towards the table, and Dusk was getting behind her.

“Listen, I... I gotta tell you something,” he whispered to her. “I’ve never done this before. Do... do you think I’m ready?”

“Why don’t you take a look at this, lover boy,” Twilight said, “ask me again if you’re ready.” Twilight lifted her tail for him, exposing her vulva and ass. She flexed her muscles and her pink, thimble-sized clit parted her deep purple pussy lips and stuck out, taunting him.

Dusk lunged at Twilight. At only the last second did he realize he was supposed to get on top of her and not drive himself into her. He only managed to get his head up past her tail. His shoulders bumped into her round, soft rump and pushed her into the table. His front hooves dangled, just an inch off the floor.

He leapt up again and this time successfully mounted her. He squeezed his legs around her waist tightly. He flexed his cock up towards her. For a second he felt with the tip of his dick the warm, fleshy heaven of her outer pussy, then he slipped inside of her.

“Oh, Celestia!” Twilight moaned. Dusk had it stuck all the way in for a moment as he shuffled his hind hooves on the library floor. Then he set his hips to pumping.

For Twilight, it was one of the shortest sessions of sex that she had ever had so far; her new lover had a hair trigger. It was also the most satisfying. “Heat” she always thought, was a poor term for what it actually felt like. There wasn’t an actual sensation of heat. Yet there was an overwhelming sense of relief now that she was being good and properly fucked. It reminded her, on a certain level, of the relief of slipping into a cool pool of water on an unbearably hot day. She was so wet she was dripping. There was a little puddle on the floor between her hind legs.

She soon started to cum. “Oh Celestia! Oh Celestia, I’m coming!”

“Shhh!” her librarian lover said. It was the only thing his heavily occupied mind could think to say. It was like a reflex.

“Oh Celestia,” she whispered. “Fuck me. Fuck me. Aaaaaahhhh.” She stifled every sound as a massive orgasm rocked her body. The only sound that could be heard was the slapping of Dusk’s hips against Twilight’s ass. Then there was the gasp as he himself came. He shot his load into Twilight. He pumped a few more times. He hopped off of her, and his diminishing cock came sliding out, adding some of his white cum to the puddle of her wetness on the floor.

She turned around to face him, still stunned by the suddenness of it, and the intensity of the passion. They pressed their necks against each other. They parted and each felt the hot breath of the other on their ears. They sat back down at the table, without having said a word. Their manes were disheveled; their sweat had worked to a lather. They picked up the fallen books, and placed them back on the table. Not knowing what else to do, they started reading again, silently. A couple of library patrons came and went, without noticing anything. Again they were alone. Dusk was searching the books for a million new questions he just had. Several minutes later, he looked down at his lap. He had another massive erection.

So they did it again.
