Chapter 1

Pound Cake flew down from the night sky, sweat on his brow as he finished his daily exercises. He had to stay in peak shape for his Tae Kwon Do tournament, and flying always got his heart rate up.

He trotted through the doors of Sugarcube Corner, seeing his Mom and Dad busy behind the counter. They had an order to fill, and decided to spend their night working on it. They'd be busy until sunrise, based on what he'd heard, but he knew they could do it.

He trotted up the stairs, passing by Pinkie Pie's room. Her door was closed, which was a little atypical; she was probably at a party with her friends. Pound chuckled to himself. That mare sure did love her parties.

It didn’t take much longer to get to the end of the hallway. He opened the door, walking into the well-lit room. He spied his sister on the lower half of the bunk bed, reading to herself.

Pumpkin Cake looked up. There was her brother, all right, sweaty and tired from exercise. He was a well-built stallion though, from all the practices and tournaments he did. He would often win, given his propensity to strike hard and strike fast.

"Back from yet another night flight?" asked Pumpkin, setting down her book.

"Yup! Was a piece of Cake!" He giggled. "I mean, no sweat!"

Pumpkin giggled as well. "No sweat? Then what's that on your brow?"

Pound quickly wiped his forehead with a hoof, replying "Nothing, nothing!"

"Anyway," he continued, "It's time for me to get some sleep! I'm pooped!"

"Alright, Pound, go ahead and turn off the light."

The stallion did so, flying up to the top bunk and settling there, lying back. Pumpkin lit up her horn, creating a little glow for herself as she continued to read.

However, something was wrong.

As she tried to read, she heard a faint shuffling noise. She tried to ignore it, but it was a little too loud, nagging at the back of her mind. She tapped lightly on the wall, and the shifting seemed to stop, but before she could read another page, the noise started up again.

Pumpkin sighed. She crept out of bed, trying to look for the source of the noise. After searching her room, she found it was coming from the top bunk. She brought her horn a little closer, and saw that her brother's blanket was rustling slightly.

Ah ha! she thought to herself. I bet Pound is trying to sneak in a snack! He's so greedy, always looking for a second dessert. I'll catch him red-hoofed!

She snuck up onto the top bunk, placing her hooves on the top of the rustling blanket.

"I've caught you!" She exclaimed, pulling the blanket down. She did not, however, find her brother enjoying a tasty morsel.

Instead, her eyes saw a very surprised pegasus, his hooves reaching on his underbelly. Looking down, she saw a thick stallioncock between the set of hooves coming to a quick halt.

Both siblings were frozen there, taking a moment to process the scene. They then both immediately blushed heavily, Pound turning himself while Pumpkin tried to look away.

"Sorrysorrysorrysorrysorry!" gasped Pumpkin, trying to avert her eyes. Pound was too shocked to speak, simply trying to hide his erection against the bed.

"I just thought--! I thought you were eating--!" Pumpkins words were short, trying to explain herself despite her embarrassment. However, despite her efforts, her eyes continued to wander down.

Her brother hadn't done a good job of turning himself--she could clearly see her brother's thick, brown cock against the blue sheets. It was quite large, and quite impressive. She'd bet it probably tasted--

Pumpkin tried to shake herself off, blushing even harder. How could she be thinking this about her brother?

Pound tried to bury his head in his pillow so he wouldn't have to look into his sister's eyes. Here he was--caught by sister with his hooves right on his stallioncock. If only he had been more careful!

However, his head was not clear. He had clopped quite a bit before his Sister arrived, and his arousal was still very high. His mind started to drift, imagining a sweet mouth to help him get release--the sweet, warm mouth of the mare right next to him, his sister--

He pressed his head into the bed a little harder, his blush quite visible in Pumpkin's horn's light.

The two twins remained still for many moments longer, trying to convince themselves to move, but being unable to. Pumpkin's mind was going crazy--she wanted to try that thick member, but--

Her mind finally got the best of her as she opened up her mouth to speak.

"U-um, bro? I...is it okay i..if I watch?"

Pound could hardly believe his ears. His entire face must have been red at this point. However, that lingering bit of pleasure in his mind took over, and he slowly turned his body over, presenting his erect stallioncock completely to his sister.

Pumpkin gulped. There it was, in all its glory, right in front of her face. Her eyes widened, watching intently as her brother's hooves returned to his cock, slowly starting to run along his impressive length once more. The mare watched intently as her brother slowly pleased himself, his hooves caressing his member, which was twitching gently in pleasure.

Pound's head was still pressed against his pillow, but his pleasure was showing on his face as she started to breathe a little faster, the thought of having an audience--his sister, no less!--augmented his pleasure. His hooves started to shuffle a little faster as he let out little groans, letting himself show his pleasure for his sister.

Pumpkin was completely mesmerized, watching the hooves glide up and down, up and down, up and down. A sort of desire started to build into her, and she opened her mouth once more.

"P-pound? I...is it okay if I do it?"

The stallion froze. Of course it was better when someone else did it, but...

"O-okay, Pumpkin."

Pound let his hooves fall to the side, his stallioncock craving the new attention. Pumpkin slowly moved hers up to replace them, resting herself on her brother's flesh. It was so warm, and so hard--she could tell that her brother was very aroused.

Slowly, her hooves began to mimic his, sliding up and down the shaft. Pound shivered as he felt his sister start to please him. Her hooves were so soft and delicate--the sensation was absolutely wonderful, and pleasure was racing through both his loins and his mind.

Pumpkin started to shift her hooves a little faster as she felt her heart rate increase, very turned on at the thought of how much pleasure she seemed to be giving her brother, based on his heavier breathing and gentle groans.

"P-please, Pumpkin...Just a little more..." escaped the stallion's lips as she shut his eyes tight. The cock in her hooves was starting to twitch a little more, her brother's hips gently rocking back and forth in time with her strokes. Pumpkin nodded, speeding up her strokes a little more, making sure to run up and down the entire impressive length of her brother's shaft.

Pound could hardly think straight--he was on the brink of orgasm, his mind filled only with pleasure and the thought that his sister was there, helping him get off. Before long, he felt his cock start to tense, and let out a moan, a little louder than before.

"Oh, Pumpkin~!"

Pumpkin felt the cock twitch even more in her hooves, still shifting as she saw her brother shoot his cum hard onto his chest, the white liquid flying and landing on his beige fur as he shut his eyes tight, gasping and moaning. As she continued moving her hooves, she saw her brother slowly stop his twitching, the last of the cum depositing onto his chest as he started to pant silently.

Pumpkin lifted her hooves of her brother. There he was, lying back, panting, covered in his own seed, all thanks to her and her hooves. She felt desire burning in her hips and in her mind, but decided to let her brother rest.

"G'night, Pound. Sweet dreams," whispered Pumpkin, before giving him a kiss on the cheek and climbing down the bed.

"G-g'night Pumpkin. T-thank you..." Pound lay his head back, his head swimming in pleasure, and pulled the covers back over himself, quickly drifting off to sleep.

Pumpkin lay in her bed, bringing her book back up, but her mind was distracted by a replay of the entire scene over and over again. She decided to distract herself by turning down her horn and trying to get some sleep, but not before promising to herself that she would try to get her brother to please her back another time.
