“Haah, ugh, mmnh.”

The n*pple was mashed this way and that inside Carbon’s mouth, clinging like a suction cup, sending tingling pleasure through her.

“Haah.”

When the n*pple had swollen sore, Carbon released the br*ast he had been mouthing with a wet sound. The saliva-slicked skin met the cool air and shivered finely.

Carbon lifted his face and pulled his hips back, and the c*ck that had been buried deep enough to compress his sac slowly withdrew. The c*ck gleaming with arousal dragged out slowly, scraping her sensitized inner walls.

“Aaah……”

Slap, slap! The strong thr*sts working inside her with a loud, lewd sound sent pleasure rising like an escalator. Hyde’s thighs tensed and her hips lifted sharply. Thick, viscous arousal ran from the junction in a stream, soaking her backside and the sofa. His sac struck her wet backside with a wet smack. Hyde arched her neck back and let out suppressed, hitching m*ans.

“Hyde. Baby. Look at me.”

At the heated voice, Hyde made the effort to lower her chin. Her blazing eyes met Carbon’s, burning and intent, in the air between them.

“Haahp!”

Carbon crashed their lips together urgently. His hot tongue invaded through the lips she couldn’t keep closed while she was busy moaning. The thick tongue swept roughly through Hyde’s mouth. Carbon sucked at her tongue so insistently that the saliva she couldn’t swallow properly spilled from between their lips.

“Mmmm!”

Her pleasure-soaked mind went white and blank, focused only on clenching tight below and demanding his release. Her dilated eyes flickered in front of her. At the familiar moment of cl*max, Hyde tried to draw a breath with a hik, but Carbon’s mouth still pressed against hers made it impossible. Breathing through her nose alone wasn’t enough oxygen. Mmmng, Hyde tried to push Carbon away with her weakened hands, but instead of pulling back, he breathed air into her while keeping their lips together.

She didn’t know how much time had passed. She only remembered Carbon’s whisper saying they had two days off and nowhere to be, so they should spend the whole time together. She might have already been up for a full day. She had drifted off to sleep in the middle from exhaustion and woken up again, after all. Even then, Carbon’s c*ck had still been inside her.

At least right now there was nothing in her p*ssy. If his massive c*ck had been buried inside her the entire time she was unconscious, her opening might have been completely ruined, so that was a relief.

But with the stopper that had been plugging her gone, she could feel the c*m that had been filling her thickly leaking out in small amounts. She had come and fallen asleep and woken up again, and it was still running rather than drying. Had Carbon come again while she was out? She wanted to find out what had happened, but the moment he confirmed she was awake, Carbon settled between her legs again and made it impossible.

“Slept well?”

Carbon gave a casual morning greeting and brought the tip of his c*ck to her loose entrance. The swollen, massive c*ck slid in without resistance.

“Ahmmnh.”

The lewd passage, accustomed to Carbon’s c*ck by now, welcomed the intruder filling the emptiness it had been left with. Feeling the pliant inner walls, Carbon thr*st with enthusiasm, and with every drive of his c*ck the c*m that had been pooled inside mixed with thin arousal and gushed out in spurts.

“I, enough, now.”

“Why, this says it loves it.”

Carbon gestured toward Hyde’s p*ssy, which kept flinching and gripping his c*ck tightly.

“Or do you not like this position?”

“No. Hng!”

Carbon, kneeling upright, pulled Hyde’s legs toward him and her backside lifted slightly off the bed. He pressed her thighs down against the sheet from there, folding her body so her feet rose above her head.

Carbon gripped the backs of Hyde’s knees and drove his c*ck in vertically like a pile driver.

“Haahk!”

Hyde lurched at the sensation of being reached to the cervix in one stroke. Carbon pressed his substantial weight down on her and continued the motion. The relentless driving pushed the pleasure that had already reached its limit over the edge.

“Haahng! Mmh, ahng!”

Hyde tried to cry out freely but Carbon caught her lips. Haahp, her m*an was swallowed into Carbon’s mouth at the same moment Carbon drove the c*ck he had pulled back to just the head in hard.

Mmmng! Hyde’s m*an, unable to escape, was desperate. Carbon’s firm chest and arms and legs all pressed against her trembling body.

Sweat-damp skin pressed and rubbed against sweat-damp skin. Hyde’s large, round br*asts were flattened against Carbon’s hard body, losing their shape entirely. Her chest felt constricted, but a strange pleasure rose from her aching n*pples.

But for Hyde, worn to exhaustion from being pushed to her limits for so long, the pleasure had reached the point of feeling like pain.

When Carbon’s mouth finally lifted from where it had been biting and sucking at her, Hyde seized the moment and pleaded in a wet, breathless voice.

“Mister…… I can’t take any more, hng, ahng!”

Carbon looked down at Hyde’s flushed face, warm and reddened with heat. Her large eyes were moist and looked up at only him with desperate longing. Carbon pressed kisses to her forehead, the corners of her eyes, her cheeks, soothing her, but he didn’t stop despite her pleas.

“Carbon. Forgive, hng, forgive me……

“……Are you never going to do it again?”

“Mmh, hng, yes!”

Carbon held the softly clinging Hyde and didn’t stop his hips. Thr*st after thr*st, mercilessly targeting only the most sensitive spot with force.

“Say it properly.”

“I, hng, I won’t, hup!”

“Won’t what?”

“My ability, carelessly, hng, use, won’t, ahng!”

Only then did Carbon smile and gently rub her ear. Tears pricked at the tender touch.

“Good girl.”

“Then, mmh, now, stop, ah!”

“Alright.”

But contrary to the compliant answer, his c*ck drove deep and forced her womb open with a rough pressure.

“Haahng!”

The c*ck throbbed at the deepest point and released. Tangled tight against Carbon, Hyde trembled as she felt the stream of c*m striking inside her.

Only after emptying the very last drop did Carbon recover his composure and gather the limp, spent Hyde into his arms. Her body came to him without resistance. Small and soft, so different from him. He felt a swell of something like pride that this body had taken everything he had wanted to give.

Carbon looked at his partner for a long moment, then lifted her chin and pressed his lips to hers. A light kiss without tangled tongues. He kept their lips touching and moved his mouth to whisper.

“I love you.”

“Me too.”

The voice that answered promptly came out cracked and rough, and Hyde laughed sheepishly, cleared her throat, and asked,

“Mister. You’re not anxious anymore, right?”

She slowly raised her hand and took hold of Carbon’s hand beside her face. She threaded her fingers between his and pressed their palms together flush before going still.

“If you ever try to leave, I’ll hold on to you like I did this time……”

Hyde looked up at him and finished the thought.

“So you hold on to me tight too, and don’t let go.”

Carbon pulled Hyde into his arms and smiled faintly, pressing his lips to her forehead.

“I’m never letting go.”

“That’s exactly what I wanted to hear.”

Carbon looked down at his endearing partner rubbing her face contentedly against his chest. Did she really know. If she knew what dark and sticky thoughts were filling his mind right now, she wouldn’t have answered so easily.

But Carbon decided not to lay all of it bare. He would push the shadowed desire down deep, and show Hyde only the parts of his heart she could comfortably receive. In a way it was deception, a kind of fraud. A decision unworthy of a hero who was always supposed to stand for justice. Knowing that, Carbon didn’t change his mind.

He could act the flawless hero in front of everyone else, but for Hyde alone, he wanted to remain the human Carbon, the one with cowardly and petty parts to him.
