It was a pleasant lavender night, courtesy of Princess Luna. The large, red earth pony known as Big McIntosh stood at the foot of a bed upstairs in the Golden Oak Library. The recently arrived unicorn in town was an odd one. Nonetheless, he found her very cute and sexy. Big Mac really liked this mare, but he was still confused about how this was supposed to work. Nonetheless, this eccentric unicorn wanted this, so he wasn't going to argue. Especially since this unicorn had connections to Princess Celestia. A mare he potentially could get to mount if he is nice to her personal student.
His monstrously large cock stood ready to mount her. He wasn’t a 30-second wonder like your average stallion, either. He was built to endure. His massive, black cock cast a dark shadow over the smaller purple pony below. The mare lay prone on the bed with her lovely rump presented to him. The sight of her tail wagging excitedly back and forth brought a smile to his face. An open book lay in front of her on the bed. She hummed happily as she read her book.
He took a deep breath, taking a moment to brace himself, before clambering himself up onto the bed. From there, he positioned himself over the mare; his legs came to touch off her sides. He lined up his cock to the entrance of her marehood. He could feel her hot marehood quivering excitedly against his tip below.
"Uh, miss Twilight Sparkle, are ya sure about this?" he asked.
"Yeah. Just try to go slow and gentle, then I should not be too distracted while reading my book."
“Hmm, should we get ready first? Ah mean, this is probably going to hurt a lot if Ah go in dry.”
Twilight groaned in annoyance. “Big Mac, stop! I am trying to read. I don’t have time for that! Just stick your massive dick in me already!” she said in a stern tone of voice.
He shrugged; by raising his two front forelegs for a brief moment. “Well, alright, but don’t say Ah didn’t warn ya.”
The stallion braced his back hind legs tightly together before he pushed forward into the mare. Immediately, upon entry, he could feel her marehood clampdown hard around his thick tip. The mare before him pulled her head back to utter a loud neigh at the feeling.
Twilight turned to look back at him with a frown on her face. “Big Mac! Don’t be so distracting!” she said in a stern voice.
Big Mac merely nodded in answer. Twilight smiled at this, before returning to reading her book. With that, he slowly pushed into her, giving her inch, after inch of his long and thick cock into her. The mare before him moaned and made the occasional quiet neigh as he gradually made his way into her. Twilight found it impossible to read her book. Her eyes were closed throughout the whole ordeal. The tightness of her marehood made it very difficult for him. Nonetheless, he continued on with the slow journey. He found himself uttering moans, and the odd quiet neigh, at the feel of her hot, slick marehood oh-so lovingly squeezing down on his invading member.
When he finally bottomed out inside the mare, his hefty balls came to smack against her lovely rump with a light slapping sound. It took Twilight a moment to get her bearings, before she opened her eyes, and returned to reading her book. Big Mac remained still, he was quite content to have his cock held within the tender grasp of Twilight’s marehood oh-so lovingly squeezing down on his cock. Big Mac was rather fearful if he started moving, it could distract her from her book.
For quite some time, he watched Twilight below, humming happily as she read her book. On occasion, Twilight would light up her horn with a deep pink glow and turn to the next page of her book with her magic. Despite not moving, Big Mac found himself enjoying himself too. Twilight, after all, was giving his cock tight squeezes with her strong vaginal muscles.
Eventually, Twilight looked back at him, and gave him a questioning look, her right eyebrow quirted upward. “Big Mac, you don’t have to be a statue. You can move if you like.”
“Uh, Ah’m not sure if that’s wise. Ah may distract ya from yer book.”
She rolled her eyes at him. “Just go slow,” she said sternly, before returning to reading her book.
The stallion hesitated for a moment, before pulling back by a couple of inches. He took a deep breath before he gently thrust forward. His balls came to gently smack against her lovely rump with a light slapping sound of flesh, slapping against flesh. Twilight gasped; her marehood clamped down hard on his massive invader.
Twilight turned to face him, glaring daggers at him with her eyes narrowed to slits. “Big Mac! You're distracting me from my book!” she said in a stern tone.
Big Mac sighed; shaking his head. “Twilight, Ah don’t know if ya realized this… but even slow and gentle sex is mighty distracting. Especially since Ah got probably the biggest penis in all Ponyville… if not Equestria, or even Equus itself.”
Twilight smiled sheepishly, her cheeks lighting up with a pink colour. “Oh… well, this is the first time I had sex. So, I had no idea.”
“Really? Ya took it like a champ. No blood or anything.”
“Well, I heard it was painful for your first time. So, I used some pain-dampening spells. I thought such spells would prevent me from being distracted. But your massive penis seemed to override my magic in that regard.”
“Well, Ah know a stallion who is a real shorty. Perhaps Ah could talk to him for ya, and ya two could–.”
“No!” she said in a raised voice. “What would be the point of that? I want a big dick to fuck me while I read a book.”
“Well, okay. Ah’ll try my best not to distract ya from yer book. Ah now have a good idea.”
With that, Twilight returned to reading her book. The mare hummed happily as she read her book. Big Mac gave her a couple of minutes to read her book in peace, before he slowly pulled back by a few inches, and then gently thrust his hips against her. The mare before him craned her neck back to utter a loud whinny. However, once she came down from her high, she returned to reading her book. Big Mac gave her a bit of time to read her book some more before he pulled back a little again and gently thrust against her. More or less the same thing happened, but this time Twilight uttered a moan. He gave her some time, before doing the same thing again.
Rinse and repeat, he did this throughout the night. This was some very strange sex with this odd unicorn, but Big Mac was willing to go along with it. If this was his chance to tap Princess Celestia's big fat butt in the future, then so be it. Big Mac was glad to do his patriotic duty for Equestria.
