At the autumn festival, Tatsumaki walked out of the festival with a toffee apple in her hand. The little esper was dressed up as a witch this Halloween; clad in jack-o-lantern leggings, her usual slim black dress, along with a pointy hat.
She was suckling this toffee apple like it was a lollipop.
"I wonder where Fubuki is," mused Tatsumaki.
Glancing to the left, the esper spotted Saitama standing outside a food truck with Genos. Little green eyebrows furrowed at the sight.
"Not him," she grumbled.
Drawing near the bald hero, Tatsumaki was still licking the toffee apple she had in her hand, softening parts of it but not actually biting into it yet (toffee apples are a pain). She glanced at him up and then down, seconds before she let out another grumble in frustration.
"So, you think you're the best hero out there, baldy?" Tatsumaki asked, assuming.
The esper flicked a glance over to Genos standing beside Saitama, and a third grumble escaped her mouth.
"I don't expect much from you, baldy. It's no wonder the demon cyborg is here, too. If a monster were to show up now, he would be there to protect you."
Glancing at Saitama's hero suit, Tatsumaki still wore such a blank expression on her face.
"Dressed in your hero outfit for the halloween festival? How original," she rolled her eyes in contempt. "You didn't even bother to dress up as something scary. You should have dressed up as a Paradiso, or maybe even Humpty Dumpty. Those would have been good costume choices for you, B-class baldy."
Like per usual, Tatsumaki was talking nothing but shit.
However, Saitama and Genos were in the middle of a conversation, talking about what to buy at the food truck. They were both blankly ignoring her.
Getting annoyed, the little green ball of angst used her powers to lift rocks from the ground with one hand. Tatsumaki could only use one hand since she was holding a candy apple with the other. The force of her telekinetic powers even picked up rocks from the roof of the food truck as well.
"Don't ignore me!" Tatsumaki groaned.
"Uh...little lady," the food truck owner spoke. "Don't do that here. It's a special occasion today," the owner warned her.
Well, she didn't give a shit.
Watching from afar appeared to be a familiar bad guy; it appeared to be a guy dressed up as a black cat sitting on a lamppost. This happened to be Sonic. He couldn't help but observe the scene taking place. Sonic had always liked watching a bit of drama.
"It's that midget again," snickered Sonic. "And she's full of rage."
Watching some more, Sonic swallowed his own spit the minute he noticed Tatsumaki using her telekinetic powers. The esper appeared to be lifting various rocks around her, controlling them.
"She can't do that; she'll fight Saitama and that's my job to do that," mumbled Sonic. "I want to fight Saitama."
Pulling out a shuriken from his belt of various weapons, the swift ninja tossed this shuriken in the moody esper's direction. Once this blade was thrown, Sonic quickly moved from his current spot. Bolting over to the food truck, Sonic watched the conversation even closer.
Attacking the shuriken with a rock thrown with telekinetic force, Tatsumaki left this shuriken shattered into pieces. Growling, the esper glanced in this shuriken's direction, but she didn't notice anything. Nobody was there.
"Where the heck did that come from?" Tatsumaki questioned herself. "It's that stupid ninja playing tricks on me. Again."
"I think you should eat something fatty every once in a while," Genos advised Saitama. "It won't affect your strength. It'll just be for one day."
"Nah, I'll get something with seafood in it," replied Saitama. "It's healthier."
Turning her attention back to Saitama and Genos, the esper grumbled when the two were still ignoring her. They didn't even notice the shuriken attack. Heck, Genos didn't even detect Sonic nearby.
But then, a second shuriken was thrown in Tatsumaki's direction, and Tatsumaki repeated the same move as before. She completely shattered this shuriken with the blast of a rock.
"That idiot," groaned Tatsumaki. "At least he dressed up as something for Halloween."
"Hello again, midget," Sonic laughed spitefully. This wasn't even banter. "You're moody, too. Time of the month, is it?"
"TINY?! I'll tear you apart, stupid ninja," snapped the short esper. "Do you want me to bust your head in?"
"Now that would be a fight," replied Sonic. "But I want to fight Saitama. You're not worth the fight with that weak, frail body."
Using her telekinetic powers, Tatsumaki lifted the wings of that purple scarf around Sonic's neck and soon used them to tie Sonic's wrists together. The force of this caused the ninja to slip off the food truck, soon hitting the ground. Tatsumaki smirked when she saw the shinobi lying beneath her feet now.
"Ninja, I'll show you what happens to boys that don't listen to me. Do you remember what happens?"
"What? That again?" Sonic questioned, cocking his head to one side. "You're gonna teach me a lesson just because I called you short?"
Pulling the candy apple away from her lips, the floating esper shoved her favourite candy apple into Sonic's mouth. In rage, Tatsumaki pointed a finger at Sonic.
"Shut up, shitty ninja," demanded Tatsumaki.
"You should follow my workout routine," suggested Saitama in the background. "I made a workout schedule just for you, Genos."
"Thanks, master," answered Genos. He soon changed the subject, however. "Hey, master, did you know Sonic was there? And he's dressed like a cat."
Genos pointed a metal finger over to the shinobi that was laying on the ground, gagged and his wrists were tied up. Genos wasn't really bothered about Sonic being in such a state. Heck, he just shrugged his shoulders at the sight. Did he notice Tatsumaki with him? No.
"Oh, hey Sonic," greeted Saitama with a blank look on his face. "Didn't see you there, sorry."
"B-class baldy," grumbled Tatsumaki. "Demon cyborg."
"So, Genos," the bald hero turned his attention back to his disciple. "About the workout routine-"
Screaming, Tatsumaki interrupted Saitama and Genos. Controlling the wind and rocks like before, the moody esper immediately sent an angry tornado in their direction. The demon cyborg wound up being blown away by this strong wind, while Saitama stayed standing like a chunk of iron.
"GENOS!" Saitama yelled. "Hold on!"
Performing a leap in the air, this jump left cracks and deep footprint marks in the concrete ground. Saitama chased after Genos. Now, Tatsumaki was left alone with the tied up shinobi.
Turning to face Sonic once more, Tatsumaki boomed yet again. "Since you interfered as per usual, you have to give something back to me," growled the esper. "Remember when we first met, ninja? I became your mistress."
It wasn't like Sonic could even respond to Tatsumaki, he had a toffee apple wedged in his mouth. He could feel his jaw ache already. He raised a curious black brow at Tatsumaki's statement.
'Interfered? Saitama wasn't even talking to you. And I didn't know you were actually my mistress...I thought that was a one time thing,' mused Sonic.
But Saitama managed to talk to Sonic.
Floating towards Sonic now, Tatsumaki brushed a few black strands out of Sonic's face. He was too pretty not to look at. Large pretty grey eyes; a pointy nose; an oval-shaped face, and purple tick marks underneath his eyes. Tatsumaki smirked.
"You look very nice today, ninja," remarked the floating esper. “I don’t usually compliment other people, and especially not villains.”
Taking the candy apple out of Sonic's mouth, Tatsumaki still wore such a wide smirk on her lips.
"Perhaps the ninja would like stuff up his ass again? I remember when you used to beg for it, long before you started playing bodyguard for Zeniru. And long before you met Saitama."
‘Huh? This midget wants to penetrate me again? I remember when she used to shove large batteries and rocks up my butt,’ thought Sonic without saying anything. ‘She used anything she could find. She used those powers of hers.’
"And do I have a choice?" Sonic finally asked with a smirk. "Right outside this food truck, really?"
"Who was the one that started throwing shurikens, hm? It was you, wasn't it?" Tatsumaki questioned with furrowed green eyebrows, hands resting on her hips. "And you called me short, blamed my mood on my period-"
Sonic interrupted.
"You are short and moody," stated Sonic. "There's no denying that, brat."
“Brat?!”
Screaming, Tatsumaki plunged the candy apple back into Sonic's bitchy mouth.
Giving life to Sonic's sword, Tatsumaki raised both hands in the air and this controlled the movement of the ninjutsu. Sonic's grey eyes were fixed on the floating sword, especially since that was his precious blade. The silver blade slipped out of its sleeve, and it now wandered in the air.
‘...What?’ Sonic thought. ‘What's this moody brat doing with my sword?’
He couldn't talk; his mouth was clogged up again with the toffee apple. Sonic was suckling on the sweet again.
Within seconds, Tatsumaki pressed the handle of the ninjutsu sword against the ninja's anus. At the minute she pierced his tight butthole with the handle, this caused a tear to pierce in his suit. Now, Sonic's hole was exposed. Tatsumaki allowed the handle of the sword to sink in deep.
"To be honest, the handle of your sword looks like an anal dildo anyway," mentioned the esper. "I'm sure you'll enjoy this in your pretty ass, ninja."
‘Oh my,’ hummed the ninja behind the toffee apple. ‘I've never thought of this before.’
Glancing down at the ninjutsu, Sonic watched the handle move deep into his hole. He flung his head back the second he felt it press onto his prostate, and all that could be heard behind the gag was a high-pitched squeal.
“You like that, don’t you?” Tatsumaki grinned devilishly.
"Come on, let's go back to the festival and I'll get you a drink," offered Tatsumaki. She held out a hand for the ninja to take.
"What, orange juice again?" Sonic questioned the small female. "If I remember correctly, that's what you bought me back at the ninja club you were 'investigating'."
"That was a mission I was assigned by the Hero Association," stated Tatsumaki. "A stupid mission. I had to search the ninja club since there was a serious threat going on that affected Z-City."
"It wasn't the first time a nightclub for ninjas had been crashed by a psycho esper," mentioned a cheeky Sonic.
"Say that again if you want a smack."
Sonic merely grumbled in response to that.
"I'll get whatever drink they have at the festival. If it's orange juice, you'll have to suck it up and live with it."
"Fine."
