Sonic's Hard Day

Sonic's Hard Day

Sonic the The Hedgehog was so happy as he sped through Ponyville. He had been busy fighting Dr. Egghead in his universe for so long that he had not had a chance to visit the love of his life, Rainbow Dash. They had been trying to make plans to fit both their schedules, and they finally found the a good day. Sonic already knew it was going to be an amazing night. He hadn't had time to relieve himself in weeks, and tonight that was going to change, though he suspected Rainbow Dash wasn't going to be so happy when he came in one thrust again.

But on his way to his marefriend's house, he caught a glimpse of somepony's dark purple hair along with a calming sweet smell. He dashed back and took a closer look. The pony was even prettier than he thought. Her mane was long and curly and had a glossy sheen. And her legs, oh her legs... Sonic almost creamed his pants as he approached her and tried to feel her mane.

"Pardon me, what the fuck sir?" She said, turning around indignantly. "Do I need to alert the authorities?"

Sonic breathed heavily, trying his best not to jizz in his pants. Even the way she spoke was posh. She was the perfect lady. Sonic cleared his throat. "No, please! I'm not a stalker or anything. I'm not from here. I just thought you were really pretty and was wondering if y--"

The fancy mare scoffed, hurting the hedgehogs feelings. "Darling please, you would never have a chance in a million moons."

"Why not!?" he cried. "Not that I care." After all, Sonic already had a girlfriend.

"For starters, just look at those gloves and shoes you're wearing. They're stained and clearly old, and if I didn't know any better I would have thought you accidentally ejaculated on your clothes to make them that colour," she said, waving a hoof in front of her nose. Sonic blushed in embarrassment, and the mare smirked devilishly. "Oh, don't tell me that's actually why," she said mockingly.

"I WANT TO FUCK YOU!" exclaimed Sonic, pulling his two inch penis out of his pants. "I HAVEN'T CUM IN WEEKS!!!"

"Oh darling," her voice grew sultry, "you could never handle it, let alone my hooves." The pony grasped Sonic's penis and ran her hoof over the head. "OHHH FUCK!" Her touch was smooth as silk, and he clenched down to avoid cumming right then and there, but a few more touches sent him straight to the edge. "AHHH FUCK MY COCK IS GOING TO EXPLODE! AHHHH!" Sonic cried to the heavens as his penis exploded in a volcano of semen.

"Did I say you could come!?" snapped the mare, gripping the penis even tighter in her hoof. "You've been a bad boy." She used her other hoof and swirled it over the sensitive penis head. The blue hedgehog bucked in her grip with mixed cries of pain and pleasure, but he couldn't escape. "Oh dear, we'll have to clean you up after this," she cooed as continued to focus on the swollen red cock.

"OH MY GOD I'M GOING TO DIE, RAINBOW DASH HEEEELP!!!" Tears were fallign from the hedgehog's eyes, and he thrashed wildly, willing to do anything to stop the sensation overload in his poor dick. Suddenly, his wish was granted. He lay back, panting heavily. His vision was blurred and he was hyperventilating.

"Did you just say... Rainbow Dash?" There was something in the mare's eyes that he hadn't seen before. Oh shit. Did she know Rainbow Dash?

"N-No! You must have misheard!" he cried, putting his dick back in his pants, cum still dripping down his leg.

"Well I heard everything!" Two the creatures looked up at the sky where the voice came from. A second later, Rainbow Dash touched down, glaring angrily at them. "Sonic? Rarity!? How could you!?" She punched Sonic in the dick, and the hedgehog collapsed to the ground with a scream. Then she turned to Rarity.

"Oh darling, I can explain! He ma--" her cry was cut short as Rainbow Dash slammed a hoof between her legs as well. She squealed as her eyes rolled back in her head.

"You two can explain at my house!"

Sonic woke up in unfamiliar territory... or so he thought until he looked around for a moment. He knew this place. He had ejaculated all over the walls on his first visit. Sonic gave his head a shake, clearing his thoughts from the past. He knew he had some answering to do.

"Rainbow Dash, what the fuk you doing?" It was her. That fancy pony called Rarity. She lay on one of Rainbow Dash's couches, her legs splayed out under her as she inspected her hooves.

"I should be asking you two that," replied the pegasus, once again glaring at her two friends. "I thought you two were my friends, but you went and cheated on me!"

"Rainbow dear, I didn't know!" exclaimed Rarity, sitting up.

"Neither did I!" chimed in Sonic, still blushing slightly as he remembered the intense session he had shared with the fancy mare just hours before. "I would never have done it with your friend if I knew."

"So you thought getting a hoofjob from a stranger was better?" countered Rainbow Dash. The hedgehog fell silent, and she knew her point had been made.

"Rainbow, it's no big deal! We'll make it up to you right now," said Rarity, getting to her hooves and taking a seat beside her friend. She looked at Sonic, who met her gaze with a confused face. She sighed and discreetly pointed at Rainbow Dash's ass. His eyes lit up as he understood what she wanted.

Rainbow Dash snorted. "How?"

Rarity didn't respond, instead gently running her hoof over Rainbow Dash's flank. She felt the mare shiver under her touch and smirked. "H-Hey! What's the big deal?" muttered Rainbow Dash, shying away from the unicorn.

"Nothing, darling," whispered Rarity as she continued stroking her friend's body, eventually working her way down to her crotch. In the meantime, Sonic had worked his way over and joined the two, rubbing Rainbow Dash under her wings. The mare moaned involuntarily, growing wet between her legs. Her face burned red as she noticed it herself, squeezing her legs together. "S-Stop," she cried, thought it came out more as a plea.

"GET READY RAINBOW DASH, I KNOW YOU LIKE TO GO FAST!" shouted Sonic has a slammed his dick into her pussy.

"I'm ready," she said impatiently, grinding her anus on Rarity's hoof.

"... I'm in!" said Sonic as he thrusted.

"What the fuck? Was your penis always this small?" cried Rainbow Dash. But her world turned upside down as Rarity put a hoof under her chin, forcing her head up. "Don't worry darling," she whispered, sliding her tongue into the pegasus's mouth. "I can take care of you plenty." She put on a generous coating of Rainbow's juices on her hoof and inserted it in the mare's anus.

"OUCH THAT HURTS RARITY!" screamed Rainbow Dash, completely unaware that Sonic was still doing his best to pound her wet pussy. "YOU'RE RIPPING MY ASS APART!"

Rarity used her other hoof and grabbed Sonic's dick, forcing it out of Rainbow Dash. "Sonic, go masturbate or something," she commanded. The hedgehog stared at her in protest, but he knew better than to argue with her when she wore an expression like that. He pointed his dick at the wall.

"MOM I'M CUUUUUMMING!!!" sperm flew all over Rainbow Dash's pictures and he even landed some in his own mouth. "Tastes like shit," he commented, stroking his dick slowly.

Rarity turned her attention back to Rainbow Dash. "Now, where were we darling? Oh, yes." Rarity slid her right hoof into the mare's vagina, entering and leaving gently a few times. Rainbow Dash moaned in frustration. She needed more stimulation. Suddenly, her world shook as Rarity curved her hoof up and around. she'd never felt such intense stimulation before. It felt like she was peetrating her very core. There was something building inside her that needed to come out. "RARITY!!!! WHAT IS HAPPENING? FUUUUCK!" Rainbow Dash's eyes rolled to the back of her head as her orgasm crashed over her, spraying fluids around the entire house and into Rarity's mouth. She convulsed as Rarity keep thrusting gently, her own hooves tugging at Rarity's to halt the sensation.

The unicorn licked her lips, lapping up Rainbow's juices. "Now dear, do you forgive us?" she asked.

Rainbow Dash's eyes were glazed over, but her ears twitched at the question. "I forgive you, Rarity. I think I love you."

"I love you too, darling," she cooed in the pegasus's ear, stroking her wings gently as she settled down beside her.

Sonic cleared his throat loudly. "Fine you gay bitches! I'm going back home to fuck Shadow and you'll never see me again!" He left the house in tears and cried all the way home, but he jerked off anyway as he imagined the incredible scene he had just witnessed, his cum leaving a trail all the way from Ponyville to his home
