Her nails dug in deeper as his fingers worked her, each thrust drawing louder and less controlled sounds from her throat. She tried to hide it, biting her lip, but every movement of his hand dragged her closer to the edge.
"I—" she started, only to be cut off by a sharp curl of his fingers against that exact spot inside her. Her voice broke, a strangled moan escaping before she could stop it.
Izuku's eyes glinted. "What was that? Didn't hear you."
"Shut… up," she panted, but her hips bucked forward into his touch, her body betraying her completely.
He kept the pressure steady, his thumb now circling her clit in perfect rhythm with the thrust of his fingers. The wet, rhythmic schlk, schlk of his movements filled the air, mixing with her ragged breathing.
Her legs began to tremble hard, thighs clamping around his hand as if to hold him there. "Izuku—" she finally gasped, her voice shaking. "I… can't…"
"Yes, you can," he whispered against her ear, his tone low and commanding. "You're gonna let go. Right here, on my lap. I want to feel every second of it."
Her head tipped back, eyes squeezing shut as heat coiled tight in her core. The pleasure became unbearable, almost blinding, and then—
Her body went rigid before shattering in waves. "Ahh—! F-fuck!" she cried out, hips grinding helplessly against his hand as her climax tore through her.
Her thighs quivered around him, every muscle in her body clenching and releasing with each pulse of ecstasy.
Izuku held her tight with his free arm, keeping her pressed against him as his fingers slowed but didn't stop, dragging out every last shiver and whimper until she sagged against his chest.
When it was finally over, she slumped forward, her breath hot against his neck, hair sticking to her flushed face.
He smirked, pulling his hand from between her legs and letting her feel the absence. "See? Told you I'd make you remember."
Mitsuki's eyes fluttered open just enough to glare weakly at him, though the fire in them was dulled by the haze of release. "Cocky… little bastard…" she muttered, but her voice was soft, almost grateful.
Izuku leaned in, lips brushing her ear. "You haven't even seen cocky yet."
He listened closely, every sound from upstairs feeding into his awareness. Katsuki was still in the bathroom, his low, miserable groans carrying faintly through the ceiling.
Up there, Bakugo was bent over, elbows on his knees, pale and sweating as he stared down the floor tiles. "I shouldn't have eaten that much… damn half-and-half for challenging me…" he muttered through gritted teeth, clutching his stomach.
Downstairs, Izuku's lips curled into a slow smirk. 'Perfect… I think we can go to the next stage.'
He leaned in, his breath hot against Mitsuki's ear. "We're not done, by the way."
Before she could answer, he shifted, his hands locking firmly around her thighs. In one smooth motion, he lifted her — as if she weighed nothing — and rotated her in his grip until she was straddling him, her back pressed to his chest. The strength behind it made her stomach twist with heat.
She looked at him over her shoulder, brow furrowed. "What are you doing?"
"What else?" he said, voice low but firm. "That was just a puddle earlier. I want a flood." His hand slid down, slipping between her thighs from behind. "Now… take them off."
For a brief moment, Mitsuki froze — her pride fighting against his command — but the heat between her legs won out. She stood, her breathing shallow, and bent forward slightly.
Her fingers hooked into the waistband of her pants, tugging them down over her hips. The motion forced her ass high in the air, round and perfectly framed in his view. Izuku didn't hesitate — SMACK — his palm met her cheek in a sharp slap that made her gasp.
She covered her mouth instantly, eyes widening in surprise. 'Why… did that feel good?'
When she turned back to sit, her pants and panties were gone, her skin still tingling from the slap. She settled between his legs, her back pressing against him again. This time, she bent her knees and raised her legs so they rested atop his thighs — a position that left her completely exposed and open to him.
Izuku's eyes dropped instantly to the glistening heat between her thighs. His smirk deepened. "You listen well."
His hand moved in, cupping her swollen, soaked folds with deliberate pressure. The wet heat of her core spread across his palm, and he gave a slow, testing squeeze that made her back arch into him.
Izuku didn't waste a second. Two fingers slid past her soaked lips in one smooth thrust, burying deep inside her. Mitsuki's head snapped back against his shoulder, a strangled gasp tearing from her throat.
"Mm—ahh! F-fuck—!" she tried to hold it in, but the intensity was instant.
His other arm locked tight across her waist, holding her perfectly still while his fingers began their relentless work — curling just right, pumping in and out with a slick, obscene rhythm.
Schlk… schlk… schlk…
The wet sound filled the room, echoing against the quiet walls.
Her thighs clamped reflexively around his arm, but Izuku just shifted, spreading them apart again and forcing her legs wide over his. "Don't fight it," he murmured, his breath brushing her ear. "Take it."
Her body trembled, eyes squeezed shut as tears welled in the corners. Every thrust had her closer — her breathing hitching, muscles tightening — until she was right there, ready to break.
And then… he stopped.
Mitsuki's eyes shot open, her hips jerking forward against his hand in desperation. "No—! W-why—?" she whispered, her voice cracking.
Izuku said nothing. He just leaned back against the couch, fingers still resting inside her but perfectly still, letting the silence stretch.
Upstairs, faint creaks of Katsuki shifting in the bathroom filtered down. The quiet was unbearable. Mitsuki's chest rose and fell, her body trembling with unspent release, her mind clawing for that peak he'd stolen.
A full minute passed.
Without warning, he moved again. Faster this time. Rougher. His fingers pistoned inside her with a wet, merciless rhythm, his thumb finding her clit and circling it in perfect sync.
"A-ahhh—! I-Izuku—!!" she whimpered, her tears slipping free now, her body bowing forward in his grip.
Again she built fast — too fast — and again, just before she tipped over, he stopped dead.
Her head lolled back, her lips parting in a silent cry, her whole body shuddering from the denied climax.
"You're… evil," she breathed, half-laugh, half-sob.
He just smirked against her ear. "Not evil. Patient."
Another long, silent minute. The tension in the air was thick enough to choke on. Mitsuki bit her lip until it almost hurt, her hips twitching involuntarily.
The third time, he didn't ease her in — he slammed his fingers in deep from the start, knuckles grinding against her soaked heat, thumb circling hard. She didn't even last thirty seconds before her legs were kicking, her voice breaking in messy, desperate moans.
Just as her climax was about to crash—
FLUSH!
The upstairs toilet roared.
Izuku instantly withdrew his hand, leaving her clenching around nothing. Mitsuki's jaw dropped, her whole body frozen in disbelief, sweat-damp hair sticking to her cheek.
"Not yet," he whispered, a wicked grin curling his lips.
