Ryuu's grin turned darker at her words. "Everything your body can handle? That's a dangerous challenge, Momo."
She shivered at his tone, her flower still leaking his seed as she lay there trembling. "I meant it," she whispered, even though her body was already oversensitive. "I want to know my limits... with you."
"Then we're going to need some help," he said, his eyes roaming over her exhausted form. "Make something for us. Something that will push you even further."
The command in his voice made her core clench around nothing, despite how thoroughly she'd just been used.
"What... what should I make?" she asked shakily, her quirk already responding to her arousal.
"You're the genius," he said, reaching out to trace circles on her trembling thigh. "What would overwhelm that brilliant mind of yours completely?"
Momo's breath hitched as she considered. Her body was already oversensitive, her flower still leaking his release. What would break her even more?
"I... I have an idea," she whispered, pressing her palm against her stomach. The familiar glow of her quirk activated.
What she created made Ryuu's cock twitch with anticipation.
A vibrating ring for him.
A small bullet vibrator.
And silk restraints in deep purple.
"The ring will make you last even longer," she explained shakily, trying to stay analytical even as her body trembled with need. "The bullet provides extra stimulation, and the restraints..." she trailed off, blushing.
"The restraints?" he prompted, taking the items from her trembling hands.
"I want to give up control completely," she admitted quietly. "I spend so much time being...well, me, making decisions. But with you... I want to let go entirely."
The trust in her voice made his chest tight even as his darker impulses surged.
"Hands above your head," he commanded softly.
She obeyed immediately, raising her arms.
He wrapped the silk restraints around her wrists, securing them to her headboard. The purple fabric looked beautiful against her pale skin.
"How does that feel?" he asked, testing the bonds.
"Helpless~" she whispered, her voice thick with arousal. "I can't move, can't control anything... it's terrifying and exhilarating~"
"Good girl." The praise made her whimper. "Now watch me put this on."
She watched with wide eyes as he slipped the cock ring over his shaft. The moment it activated, he groaned at the intense vibration.
"Oh god," he growled. "This is going to drive us both crazy."
"The vibrations should transfer during... during penetration," Momo said shakily, her analytical mind still working despite her helpless position. "Enhanced pleasure for both of us while—"
"Stop thinking," he interrupted, positioning himself between her spread thighs. "Just feel."
He rubbed the head of his cock against her sensitive entrance, mixing his previous release with her fresh wetness.
"You're still so wet," he observed. "Even after cumming so many times, you're dripping for me."
"I can't help it~" she whimpered, pulling against her restraints. "Being tied up like this... feeling helpless... it makes me so—"
He thrust into her in one smooth motion, cutting off her words with a sharp cry.
"AHHH~!" she screamed, her back arching as much as the restraints allowed. "Oh god~ the vibrations~ I can feel them everywhere~"
The cock ring's vibrations traveled through his shaft, stimulating her walls in ways she'd never imagined possible. Combined with how sensitive she already was, the sensation was overwhelming.
"Too much~!" she gasped, her hips trying to writhe but unable to escape due to his grip and her restraints. "It's too intense~ I can't—"
"Yes you can," he growled, establishing a steady rhythm. "You're going to take everything I give you."
*Plap Plap Plap*
The vibrations were affecting him too...every thrust sent shockwaves of pleasure through his cock, making him impossibly harder.
"Please~" Momo begged, though she wasn't sure what she was begging for. "Please, Ryuu~"
He reached for the bullet vibrator, turning it on. The additional buzzing sound made her eyes go wide with panic and arousal.
"No~ no, I can't handle both~" she protested weakly. "The internal vibrations are already too much~"
"You said you wanted to know your limits," he reminded her, pressing the bullet against her swollen clit.
"FUCK~!" she screamed, the word torn from her throat as dual vibrations attacked her most sensitive spots. "OH GOD~ IT'S TOO MUCH~ I CAN'T~"
Her whole body convulsed against the restraints, every nerve ending on fire. The combination of his thrusting cock, the vibrating ring, and the bullet on her clit was beyond anything her research could have prepared her for.
"Look at you," he groaned, watching her fall apart completely. "The perfect, brilliant Momo, tied up and screaming for my cock."
"Yes~!" she sobbed, all composure completely shattered. "I'm screaming for your cock~ I love it~ I love how you make me feel~"
Her pussy was clenching rhythmically around him, another orgasm building impossibly fast.
"Already close again?" he asked, increasing the pressure on her clit. "How many times are you going to cum tonight?"
"I don't know~!" she cried, tears streaming down her face from the overwhelming pleasure. "I can't count anymore~ everything feels too good~"
"That's right," he praised darkly. "Don't think. Don't count. Just cum for me whenever your body needs to."
Her next orgasm hit like a tsunami, more intense than all the others combined.
"RYUU~!" she screamed his name like a prayer, her whole body seizing as pleasure consumed her completely. "I'M CUMMING SO HARD~ OH GOD~ I CAN'T STOP~"
But he didn't let up. He kept the bullet pressed firmly against her clit while maintaining his thrusting, the cock ring making everything more intense.
"Another one," he commanded. "Give me another one."
"I can't~!" she protested even as her body built toward another peak. "It's impossible~ humans can't cum this many times~"
"You're not human right now," he growled. "You're mine. My perfect little fucktoy who cums whenever I tell her to."
The degradation mixed with praise broke something fundamental in her mind. Her sixth orgasm crashed over her before she could even process it was building.
"YES~! I'M YOUR FUCKTOY~!" she screamed shamelessly. "USE ME~ BREAK ME~ I DON'T CARE ANYMORE~"
Ryuu felt his own control slipping as her pussy convulsed around him. The cock ring's vibrations combined with her impossibly tight walls were pushing him toward the edge.
"Where do you want my cum this time?" he groaned.
"Inside~!" she begged desperately. "Always inside~ I want to feel it~ want to be full of you~"
"What a greedy girl you are," he growled, but his hips were moving faster, chasing his release. "You want me to fill you up until it's dripping out?"
"Yes~! Fill me up~ breed me~" The words tumbled from her lips without thought. "I want to be so full of your seed~"
The breeding talk pushed him over the edge. With a final deep thrust, he buried himself completely and came hard, the cock ring's vibrations making his orgasm more intense than he'd ever experienced.
"Fuck~!" he groaned, his whole body shaking as he emptied himself inside her.
Momo felt the warmth flooding her again, triggering one final, weak orgasm that left her completely boneless.
"So much~" she whimpered as he slowly pulled out, cum immediately beginning to leak from her well-used pussy. "There's so much inside me~"
Ryuu quickly untied her restraints, gathering her trembling body into his arms. She was completely limp, exhausted beyond measure.
"Are you okay?" he asked softly, his dominant persona melting away due to post-nut clarity, as concern took over. "Did I push too far?"
"No~" she whispered against his chest, her voice hoarse from screaming. "It was great~ you were great~ I never knew I could feel like that~"
"You were incredible," he assured her, stroking her damp hair.
"Was I really?" she asked quietly, that need for reassurance showing through her exhaustion. "I got so... loud. And I said such shameful things..."
"You were exactly what I wanted," he said firmly. "Never apologize for how you respond when we're together."
She smiled weakly, snuggling closer to his warmth. "The theoretical framework for multiple orgasms severely underestimated the practical applications~"
He laughed softly. "Even completely fucked out, you're still analyzing."
"Can't help it~" she mumbled sleepily. "Though I think my brain might be permanently altered by tonight's data collection~"
"Good," he said, pulling the covers over both of them. "Sweet dreams, my brilliant girlfriend."
"Mmm~ sweet dreams~" she whispered, already drifting off in his arms, completely satisfied and thoroughly claimed.
The fairy lights cast a gentle glow over their exhausted bodies as they fell asleep tangled together, both completely spent from their thorough exploration of pleasure and limits.
