NeonHorizon: Warning. This gets pretty mature.

Ayano's face felt like it was on fire. Her eyes widened behind her hair when she heard her fellow hero say her name. Mumen Rider?! Wait-!

"This doesn't have anything to do with you, hero. Why don't you just turn around and go back to your boring, vanilla, night at this bar?" The taunt came from Sonic, who was wearing that vicious, twisted grin.

"Let her go! She broke up-!"

"Oh? You think you know everything about our relationship? Go on, then. Tell me to leave her alone. Tell me she doesn't want to be around me anymore. Let me hear what you think she really wants."

The bespectacled hero leaned against the doorway of the restaurant, still looking kind of tipsy. He pushed up his glasses, the cat scratches on his face oozing fresh blood and adding to the look of utter weakness. "Let her go," he slurred. "Or I'll…" A sharp cry of alarm escaped him as he was suddenly being lifted off his feet by his neck.

"What are you going to do? You sounded so sure of yourself a second ago." Sonic watched him thrash, kicking uselessly at the ninja as both hands gripped Sonic's wrist to try to pry his hand away.

Ayano had been thrown off when he had caught her, but now that she saw her friend in trouble, her body acted before her brain could form a plan. She closed the distance between herself and Sonic in a matter of seconds, reaching out to try to help Mumen Rider.

Sonic moved before she could get within an inch of touching him. Crouching on the rooftop of the building, his grin was wide and evil. Excitement was clear in the man's grey eyes as he stared down at her. His grip on Mumen Rider's neck had changed. He now had the hero's throat pressed into the bend of his elbow. His position at the edge of the roof allowed him to dangle the hero over the front of the two-story building, at least twenty feet above the sidewalk.

"What's wrong, Ayano? You look confused. Did you think you could catch me?"

"P-put him down!" She felt anxiety twist her stomach, churning the food and alcohol that had settled there. Her friend was thrashing as he tried to free himself. Legs kicking at empty air, fingers clawing at Sonic's arm frantically. If something happened to him, she would never forgive herself.

He's a pure hero! I can't let him die like this! At the same time, she was worried because she knew she was no match for Sonic. He was stronger, faster, and more skilled. If he wanted her dead, she would be gone in an instant.

"You want me to put him down?" Sonic quirked an eyebrow, his grin spreading a little more. "Is that really what you want?"

"N-no! I mean-! Don't hurt him! He doesn't have anything to do with this! It's between you and me…so just…please…"

The rain continued to fall around them, drenching the city and speckling Ayano's glasses. She saw him look down at Mumen Rider's struggling form. The man had been fighting for his life in an absolute panic and managed to burn through his energy quickly. He was starting to move more sluggishly as his air supply decreased.

Sonic seemed to see that the hero was growing weak at the same time that she did and when he lifted his face, he looked ecstatic. "It would be kind if I just let him fall, wouldn't it?"

Ayano gritted her teeth and looked from her slowly dying friend to her ex-teacher. Her ex-lover. With that grin that could make her heart flutter. Those sharp grey eyes that made her shiver when they looked her up and down.

She sprinted down the sidewalk, boots splashing through puddles, and tried to quickly climb up the fire escape. It was slippery beneath her feet and hands, but she managed to climb up to Sonic's level in time to see him leap to the next roof. Her friend was still in his grip, but now Mumen Rider had gone limp. He was being dragged by the collar of his shirt.

The female hero had blades with her since she and Mumen Rider had been patrolling, but she was hesitant to actually fight Sonic. More than anything, she just wanted to save her friend and put some distance between her and the ninja. Just seeing him again had reminded her of how much she actually loved him. How much she missed his touch.

I can't back down now! I have to save Mumen Rider! The roof was just as wet and slippery as the fire escape, but she was prepared. Sonic had trained her well when he was helping her increase her running speed. Not to mention that the conditions of some of her training grounds had included obstacles and areas that were difficult to find footing in.

Ayano leapt after him, albeit with a bit of hesitation. Her vision was blurry and speckled from her glasses being wet. Her own wounds from the cat rescue/attack earlier were starting to open and bleed, mixing with the rain. However, she was not about to let rain stop her from saving her friend.

Sonic moved swiftly, becoming a blur in the storm as his ex-student tried to keep up with him. All the while, her friend was being dragged and slammed against the rooftop edges. When he suddenly disappeared, leaving Mumen Rider's unconscious body behind, it made Ayano's heart skip a beat.

She tensed, trying to listen for footsteps while still knowing it was no use. When she felt an arm wrap around her upper half, trapping her arms against her sides, she was only mildly surprised. Ayano fought, nonetheless. She thrashed as best she could, glasses sliding down her face and nearly falling off.

He held tightly until she finally ran out of energy. Leaning down to her right ear, his lips gently brushed against her sensitive skin. "Look at him. Isn't it laughable? He thought he knew what you really wanted. Look at him."

Ayano had lowered her head when she lost the energy to keep fighting. She was trying to catch her breath, her eyes closed and face directed at the roof beneath them. "He's a…real hero," she protested.

"Look at him." Sonic's free hand gripped her chin firmly and he lifted her face, making sure that the girl was looking at the fallen hero. "Go ahead. Call for him. See if he's still alive."

"I-I don't…ngh!" She tensed again as she felt him nip at her ear. The ninja's tongue flicked over the bite, sending an eerily pleasant shiver through her.

"Call for him," he repeated. "Or don't you care if he's alive or not?"

It was at that moment that Ayano realized that she had no idea what the hero's real name was. "M-Mumen Rider…" she quietly called.

"Louder. He's not going to wake up if you're too quiet. Don't you want him to wake up?"

"Mumen Rider!" Her voice was barely audible over the hammering rain that fell around them. She was suddenly very aware of how her wet clothes clung to her body. Aware of the warmth radiating from Sonic through his clothes. Her breathing hitched as she felt his hips press into hers from behind. "M-Mumen Rider!" she called louder.

The hero was lying on his stomach with his face to the side, directed at her. He was, unfortunately, on the next roof over. When he began to twitch back to consciousness, she was unable to get to him to check on him. The best she could do was meet his gaze through their rain-speckled glasses.

Sonic, satisfied that she was looking at her friend, grinned and released her chin. His fingers skimmed down along her neck and he felt her hips press back against him in response. He gripped gently for a moment, rubbing forward against her and knowing what it did to her.

What is he doing…? Ayano felt his hand drift lower and then clutch the left side of her chest. With the fabric of her shirt and athletic bra clinging to her skin, she was able to feel everything. When his thumb skimmed over the peak of her breast she bit back a cry of pleasure and shook her head.

"Keep your eyes on him," Sonic warned. He took the peak between his thumb and index finger, tugging gently. Her back arched and she closed her eyes. "Ayano. What did I say?"

"S-sorry…" She forced her eyes back to the direction of the hero, but her face was burning pink with a blush. She could feel warmth spreading throughout her body, starting at her lower half. Pressing her thighs together, she hoped neither of the men noticed. I should fight him! I know I should! But this feels so good! And I don't…have the energy to fight…

"Good girl, Ayano." He moved his hand to the other side of her chest, repeating his earlier action and drawing a sharp gasp from her. "This cold rain really makes you sensitive, doesn't it?"

"Ngh! Sonic, please…"

"You're begging now? I thought it would take longer."

Ayano squirmed with what strength she had left, but was no match. He nudged her legs open with one of his and let his hand trail down further to the front of her skirt. Ayano's skirt began to get dragged up her thighs, little by little. All the while, she closed her eyes and bit her lip. The heat of her skin was clashing with the cold rain in a way that made everything so much more heightened.

He wouldn't…do anything in front of Mumen Rider. He's bluffing. He has to be bluffing. He wouldn't-! Ayano felt his fingers hook into the waistband of her panties and start to drag them downward. The wet fabric clung a little until it got past her thighs and then slid down easily. She shivered as cold air met her warm flesh. "S-Sonic, what-?"

He lifted her skirt the rest of the way up so it exposed her more and tucked it beneath the arm that was pinning both of hers down. Bringing his lips to her ear again, his warmth breath tickled her skin. "He's your friend, isn't he? A vanilla guy like him. I wonder if he'll still be your friend after today."

The fallen hero was still weak from being nearly strangled by Sonic; his own energy used up so that even just pushing himself up onto his elbows was a chore. When he realized what Sonic was doing, his face went bright pink and his mouth moved without words escaping.

Ayano closed her eyes tightly as she felt fingertips glide along her already wet lower lips and gasped when a finger abruptly pushed past her folds up to the last knuckle. Her head was thrown back against his shoulder as she felt him smirk, his lips moving to the side of her neck. Kisses and bites could be felt against her pale neck, heated descriptions of what he would do to her were murmured into her ear. All of this happening right in front of the other hero.

Humiliation made her face turn an almost glowing shade of red and she subconsciously bucked against his hand. He's doing this…right in front of Mumen Rider! I can't look Mumen Rider in the eye now! I'll never be able to! A moan burst from her throat as Sonic began to drive his finger in and out of her.

"You like being watched, don't you? You like having your friend watch me tease you, Ayano." Sonic heard her whimper and it drove him onward. A second finger joined the first, curling inside of her and pushing her closer to the edge. He worked them in and out at a medium pace at first, but soon the thrusts grew rapid.

Ayano could feel a tension in her lower half and it grew with each pump of his fingers. As embarrassing as it was, his words did make her feel slightly wetter. I'm sorry, Mumen Rider! I'm so sorry!

"Imagine what your little "Hero Association" would say if they knew one of their heroes was acting this way in public. You love this, don't you, Ayano? You're getting off on your friend watching me pleasure you. I bet he's getting bored though. Why don't we see how much you can take? I bet he'll like that."

Her back arched as a third finger entered her and his thumb began to rub slow circles around the bundle of nerves at the top of her slit. Face bright red, head bowed to hide her expression behind her hair, Ayano moved her hips to bounce up and down on his fingers. Small whimpers and moans escaped her, but she at least managed to bite back the louder ones.

"How does it feel?" His lips caressed the side of her neck, sending shocks of pleasure throughout her being.

"I-it feels good," she whispered.

"You're…such a bad girl. Your "Hero Association" would be shocked, wouldn't they? Their hero, getting fingered on a roof by an assassin, in front of another hero that works for them. You're letting yourself be toyed with by someone you should be trying to take to prison." A small bite to the skin between her ear and neck made her go still on his hand. "You broke up with me, didn't you? So I can do whatever I want. Maybe I'll just use you as a toy."

The ball of tension in her lower half became too much. Ayano threw her head back against his shoulder as her muscles tightened around his fingers. She felt a warm gooeyness when he pulled his fingers out a little and pushed them back in.

When he finally pulled them out all the way, it was with a wet sort of sound that made her shudder and turn an even brighter shade of red. Sonic looked across at Mumen Rider, who had gone as red as Ayano was, and lifted his fingers to his lips. He trailed his tongue along the length of each finger, making sure to lick up all of her essence while maintaining uncomfortable eye contact.

"S-Sword Girl, I'm sorry-!" Mumen Rider started to apologize.

Her knees were weak, breathing heavy. She was relying completely on Sonic to hold her up now. "I-it's okay…"

Sonic grinned and lifted her bridal-style. "Tell Saitama that she went home. Your little "hero friend" and I have unfinished business."
