"Dang it... not again!" Pound Cake mumbled to himself. He was in the kitchen, baking a cake for Pinkie for an upcoming party when he notice that he had gotten a massive erection. This had been happening for a few weeks now, ever since that trip that him and his family took at the beach a few weeks ago.
He remembered that day clearly, not because of the perfect weather, but because of his sister. She was wearing a swimsuit that was clearly too tight for her, but Pumpkin didn't really mind. Normally, Pound wouldn't ignored the sight due to them taking baths together back when they were fillies, but the sight of his sister's wet mane made him get his very first erection.
Since then, Pound Cake had been finding himself more attracted to his sister. If it wasn't her cheerful and calm personality that made his heart leap, it was the way her hips would sway every time she walked around Ponyville. Pumpkin was a knock-out. Sometimes, he found it humorous that he saw his beautiful sister as just his sibling. There was those days where he found her voice annoying and dreaded hearing it or how he hated it when she would follow him around like he was a celebrity.
But eighteen years have gone by since those days. Things were different now. He wanted her by his side. He needed her.
However, he knew that he had to keep his newfound feelings for Pumpkin a secret because he was certain that she didn't feel the same way about him. She probably just thought of him as her brother, nothing else. There was no way that she felt the same way towards him.
Yet, Pound couldn't get his sister out of his mind. She had looked so amazing in that tight swimsuit, her wet mane had been hanging free from their bows and it fell loosely on her neck as her marehood was visible through the thin material of the swimsuit.
He remember after seeing his sister in that suit, not to mention all wet, he had almost constantly gotten horny that day, and every time his sister would sneak into Pound's thoughts, he would instantly grow hard.
With a heavy sigh, Pound took off his apron and sat down on the floor, which was covered in flour and many other ingredients. It was seven o'clock at night and both his parents and Pinkie Pie were out of town for an important party while Pumpkin was spending the night at a friend's house, so nopony would catch him. Besides, it normally didn't take him very long to finish up his business and go back to baking.
Unbeknownst to him, the door leading to the kitchen had creaked opened slightly as Pumpkin Cake peeked her head out from behind the door.
Is he still in there? He's been baking all day! She thought to herself. She knew that her brother loved to baked, but she knew that he would never bake all day long! Something was going on and she wanted to know if Pound was okay.
All he had been doing for past few weeks was bake cake and cupcakes in the kitchen for their parents and had been ignoring her, and that worried Pumpkin. She cared so much for her brother, she was the one who knew him the most, and she knew, for a fact, that he would never act like this unless he was worried or nervous about something.
She slowly walked into the kitchen, hoping not to make a noise to acknowledge her presence to her sibling. She was about to call out her name when she heard soft moans coming from behind the counter. She quickly dodged to the opposite side of the counter and slowly began to crawl towards the sound. She peeked around the side of the counter, but she kept herself hidden.
"P-P-Pumpkin.." Pound Cake's voice moaned out as he stroked himself nice and slow, his face covered in dark red blush.
Pumpkin continued peeking out from the side of the counter, she had no words to what she was seeing. There was her brother, his face covered in blush, moaning softly as he stroked himself with his hoof. He was leaning against the wall of the counter, panting as he rubbed his hoof against his long and hard cock.
Pumpkin had no words and she wanted to walk away, ignoring on what she just saw. However, she couldn't look away form the sight. He looked alluring with his tongue hanging out of his mouth, letting out soft moans and pants of extreme pleasure as his hoof increased their pace.
"Pumpkin.." Pound Cake breathed out in a soft yet husky voice as dirty fantasies of his darling sister fluttered through his mind. He pictured her sitting in front of him, covered in flour and wearing that tight swimsuit that he loved. He imagines that instead of him pleasuring himself, it was Pumpkin. He imagined her lips going up and down his shaft, the thought of this was for sure going to send him over the edge.
"Pumpkin!" He began to scream out, repeating her name over and over again. "Sis, don't stop!"
Pumpkin Cake continued to watch her brother pleasure himself at the very thought of her. Her heart was racing as she felt her face rise in temperature out of both embarrassment and excitement. She slowly found herself getting aroused by the sight.
As much as she wanted to stay and watch her brother, Pumpkin knew that if she stayed any longer, she would get caught by her brother. It would make things terribly awkward between them if he found out that she was watching him pleasure himself.
Pumpkin slowly got up from the side of the counter as she tried her best to be as quiet as possible. She crawled her way towards the doorway and as she crawled, Pound's cries and moans were getting louder and louder. She paused for a moment to listen as her eyes widened at the words she heard him yell out.
"Pumpkin, I love you!" Pound cried out as he reached his climax, releasing his load all over himself.
Her hoof went up to her mouth, her face now red with blush after hearing what her brother said. Her heart was beating loudly, her eyes wide as saucers as she felt herself tremble at his words.
Not knowing what to do, Pumpkin continued to slowly crawl towards the door. She knew that her brother had finished masturbating and she was for sure that he was going to get up to wash himself off and continue baking.
She was almost to the door when she heard Pound Cake get up. He was licking off some of his cum from his hoof when he walked out from behind the counter. He made his way round the corner when he saw the sight before him. There was Pumpkin Cake, her face red with blush, her eyes wide with astonishment.
"P-Pumpkin?" Pound stuttered out as he felt his jaw drop slowly. "What are you doing here? I thought you were spending the night at a friend's house!"
Pumpkin Cake quickly stood up from her crawling position as she stared at her brother, both of their cheeks darkening by the second. "I'm sorry, but my friend got sick, so I had to go home! I only came in here to check on you, and I,um..." She stammered loudly she stared at the floor, avoiding her brother's stare, not knowing what to say.
The two siblings stood there in silence for what seemed like an eternity. Pound stared at his blushing sister and let out a sigh, rubbing the back of his head with his hoof. "How much did you see, sis? All of it?"
Pumpkin's heart began to increase its pace as she looked up at her brother, "I..um..not very much.." she whispered quietly.
"Yeah, but you were there long enough to know what I was doing. You saw me, didn't you? Or, at least heard me." Pound said, he knew that his sister was smart enough to know what he was doing. If she didn't, she wouldn't be acting so nervous and looking so tense.
Reluctantly, she nodded at her brother, not knowing how to reply. She sighed heavily before looking at her brother with a pitiful, pleading look. "Pound, there's no need to be embarrassed. I'm sorry, this was a completely invasion of privacy."
"Just forget it. Let's pretend this never happened." The colt grumbled as he walked past her towards the door. "Let's never acknowledge this ever again..."
Pumpkin's eyes began to fill up with tears as she ran to him, hugging him from behind. She wrapped her arms around him tightly in an embrace, burying her head in his fur, tears streaming down her face.
"I love you too, Pound... I've loved you for a very long time. I'm very happy you were touching yourself while thinking about me." Pumpkin whispered as she rested her cheek against his back. He smelled like vanilla and cake, causing her to nuzzle into his fur softly.
"You can't really mean that.." Pound replied, turning around to face her, a suspicious look in his eyes.
Pumpkin looked at her brother and her face lit up as she put a hoof on the side of his cheek softly. "No, brother, I really mean it. I've loved you for years! I've just been scared to tell you how I feel because I thought you only thought of me as your sister, but now I know that you love me too." She locked eyes with his, smiling brightly at him.
After a moment of silence, Pound leaned over and softly placed his lips against hers. He heard her gasp as she felt his arms pick her up from her hind legs and in her against the wall. The impact of the kiss caught Pumpkin off guard, but she wasn't going to complain. She had been dreaming of this day and she didn't want to ruin this moment.
She wrapped her arms around his neck, refusing to break the kiss. She felt his tongue lick her lips, begging for entrance into her sweet an soft mouth. Pumpkin was more than eager to fulfill his request as she parted her lips slowly. Pound moved his arms to caress her rear softly. He wrapped her hind legs around his waist as he shoved his tongue inside of his sister's mouth, she tasted like vanilla and blueberries. Pumpkin responded to this by encircling her tongue around his in fiery passion.
Pound Cake found himself hard once again and this time, he didn't care. He knew how his sister truly felt for him and he didn't want this moment to stop. A tiny moan escaped from his sister's lips as she felt him squeezed her rear softly and tenderly.
The two siblings finally broke away from the kiss, a line of saliva connected to both of their lips. Pumpkin leaned over to Pound's ear and whispered softly in his ear. "I want you, Pound." Her warm breath against his ear made Pound shiver in excitement as Pumpkin nibbled gently on his ear before bringing her lips to his neck softly. He found himself growing stiffer from his sister's teasing, something he would normally be annoyed at.
In a quick motion, Pound captured her lips to his once again, devouring her in his hungry and desperate kisses. He squeezed her rear a little harder as he broke the kiss and looked at Pumpkin, his eyes full of lust and desperation. "Pumpkin, I meant it when I said I loved you.."
With a cute and small giggle, Pumpkin kissed her brother's forehead. "I know you did. I love you, too."
Seconds later, Pound began to kiss her chest, licking and nibbling her body. Pumpkin let out a startled gasp as she felt him nibble on her body.
"Ah, aah..." Pumpkin moaned out as she felt Pound's warm tongue flicker out to taste her fur. He sucked on her soft coat as she let out cries of desire as Pound used his free arm to slide up against her leg, making his way up her silky smooth thigh.
By that point, Pumpkin was full of need and pleasure as her brother found his way to her inner thigh as he massaged her leg lovingly. He looked at his lover's face as he lined his cock up with her wet and glistening marehood. He wanted her, he needed her, more than anything in the entire world. She was the only pony he ever wanted to be with.
He rubbed his cock against her clitoris lightly, causing a tiny squeak of anticipation from the mare's lips. With a single, gentle thrust, he pushed himself inside her, letting out a tiny grunt as he did. Pumpkin bit her lip, hoping it was hiding her groans of pain but found it difficult due to this being her first time. She knew that the first time would be painful, especially with someone as big as Pound was, so she never fully prepared herself for it.
Pound put a hoof on his sister's cheek lovingly, pausing for a moment. He didn't want to hurt her until she was fully accommodated to his giant size. To make things easier for the both of them, Pumpkin pushed her lower half of her body closer to him, allowing him to slowly slide deeper into her wet, velvet walls.
Pumpkin let out a soft moan as she felt her brother penetrate her. Much to her surprise, he slipped himself out of her for a moment, only to thrust back inside in a quick, pounding motion. He continued to thrust and pound in and out of her painfully at first, causing her to squirm against him.
"Oh, Pound! Mmmph!" She yelped out as he continued to infiltrate in and out of her with swift and perfect motions. After long moments of intense thrusting, something began igniting out of Pumpkin like a firework that was about to go off. Burst of pleasure began to burst out of her after each time Pound drove himself into her.
Pumpkin wrapped her arms around Pound's neck pulling him closer to her as he continued to thrust his heavy and erect cock into her tight and moist regions. "Oh, Pound Cake, I...I don't think I can take much more!" She screamed out in ecstasy as she felt herself nearing the edge.
"Pumpkin, I love you!" Her brother cried out in desperation as his aching cock began to spasm with his imminent release as his load spilled out inside of her. Pumpkin's climax exploded mere seconds after Pound's, leaving the two siblings both panting and gasping for air.
Pound nuzzled his face in her soft neck as he slid both him and his sister to the floor. "Mmm, Pumpkin... that was amazing.." He mumbled out as he exhaled a heavy sigh of pleasure. Pumpkin's chest was rising up and down as she breathed heavily. All she could do was nod and stroked her brother's mane with her hoof.
"I love you, too, Pound." She whispered with a tiny smile as she closed her eyes slowly. "But, let's keep this as our little secret, we can't let anypony know about this."
"Yeah. Our little secret." Pound repeated, panting softly in his sister's neck. "And trust me, sis, this won't be the last time we do this. Next time, I'll let you be in charge."
This made Pumpkin Cake smile as the both of them drifted into pleasant slumber.
