Longest Love
Shining Armor went towards the round cheeks that shined with the moon. He was to penetrate deep into his favorite purple pony. The evening sky is illuminated by the full moon. Twilight Sparkle raised her plot for her secret lover. Her wing’s spread apart and fanned out. Twilight always loved her brother, ever since she was a foal their love for each other grew. Since Shining was getting older, she wanted to savor every last second he’d be alive. Even with those gray hairs on his head she still wanted him for all she could.
Twilight Sparkle had a kingdom to control and for once in a full moon their lust for each other would be met. The stress of being a ruler felt huge on her hooves. This little outing before Shining became too old would satiate her depraved needs. All she wanted was to feel that bountiful cum fill her.
“Oh Twily,” he cried. “I wonder how long can we keep this relationship going for, maybe for all eternity?”.
Princess Twilight Sparkle nodded as the scent of her brother’s precum surrounded her senses. His penis was erect and so close to her hindquarters that her spine felt a shock. Her heat energized the stallion as their two genitals met.
“OH my me, I never get tired of your cock Shiny,” screamed Twilight. “I hope you can keep that cock working for me for as long as you live, love”.
Shining Armor felt the wet flesh squeeze him. With all his strength, Shining slammed into Twilight’s inner walls and stretched them. She moaned as his girth penetrated into and hit her fleshy bead, so needing a good penile kiss. His hooves went atop her plot and he gyrated his hips at a high speed to please his beautiful sister. How her fat plot squished against his hooves aroused the white stallion to the point where he buried his face deep into their size. The sensation of two thick balloons that had powerful tension made him hump his sister even harder.
With a powerful hip slam, Twilight Sparkle raised her tongue and moaned with each furious vaginal hit. Her mane shook and went from side to side with each smack. Shining in his bliss, slapped the buttcheeks that held him high. She gave out a loud moan and felt her backside fall to the ground. Shining Armor lowered and smashed his cock into her.
“I can’t stop loving you Shiny!” said Twilight. “You are the best for bucking me, no other pony can compare”.
Her lover went near her head and nibbled on her ear. Twilight giggled at the sexual bite that caused her loins to get wetter. The penis stabbed deep into Twilight and then released a wad of seed into her aching fleshy home. It fell over her butt and back, to the point where her belly filled up. She lay down on the earth and gasped at the orgasm she felt.
This was their testament and their original sin.
Shining released himself from her bountiful womb and fired a string of seed at her stomach. It landed with a fat plop that covered Twilight in sticky streams.
“Dear, you came over my stomach darling,” said Twilight Sparkle. “And you came so much in my womb, I guess I hope I don’t get pregnant”.
Shining Armor smiled and shot another load on her sister’s face.
“No worries Twily, we are going to be happy parents if it does occur” he shook his dick of any remaining cum and laid next to his mate. “Even in my old age, I am still ready to raise, just look at my Flurry Heart.”
Twilight Sparkle felt a bit of cum flow out of her. She touched her belly in anticipation of what's to come.
“Besides, I’m still young, I’m not that Old” said Shining Armor.
“Whatever you say, it’ll be an adventure to raise another foal, almost like my many other passes of time,” said Twilight Sparkle. “I hope your penis can facilitate more offspring”.
Shining Armor smiled at the idea of her sister talking funny.
“You dastardly mare, I always love when you talk funny, it almost makes me hard if it weren’t for the fact that my dick exploded with cum into that cunny of yours”.
She laughed and pressed her divine lips on his cheek.
“Anything for you my Shining Armor”.
Then she felt a penetration slide before her hole. Shining Armor felt his erection grow full and long. Twilight Sparkle grinned and slid onto it with the feeling of his stretch deep. Electricity swarmed Twilight’s mind as he went into and out. As if he was a young colt ready to penetrate his first mare, Twilight never thought he had the power to go for a second outing. This surprised her since he was such in his age that their love making was thought to be weaker. But, that old Shining Armor still surprised her even in this age.
A filly burbled in Twilight’s hooves. Twilight Sparkle placed the foal in a comfy place as she watched it call for its mother. Then she dragged the baby within the stroller around the palace garden. She was as happy as a mother could be. No pony could take that away from her even if she was an inbred foal. This gave her insight towards her own happiness. For if she was content with this foal in her life, why would it matter if ponies would look down on such a union. All that mattered was her happiness and nothing else.
The rest could be put away. For her love was all that mattered and the joy of a shouting filly. There is no place for worries or sadness. The best thing was to continue onward to a glorious new adventure. She would always love her little star shine. Nothing in Equestria would get in the way of that forever more. Love triumphs after all and always in the end.
