"This time I'm the one that found you," Genos grins.

"I'm the one that went in search of the mosquito to kill it," Saitama replies. He arches up an eyebrow.

"You would've been killed by the Mosquito Girl if I hadn't interfered," Saitama grumbles.

"I'm sorry sensei," he says. "That would have meant another lifetime trying to find you."

"We're together again," Saitama says, as he grasps Genos hand. He looks at Genos' hand mournfully. "You don't have the mark anymore."

"I will immediately request Dr Kuseno to give me synthetic skin over my right hand, along with the mark sensei!"

"That's actually a really good idea," Saitama says, and he drapes himself over his disciple. "I want to see my mark on your skin again."

The bond between them flares. Saitama gives into the urge to bite Genos' lips.

When he firsts meets Genos, it feels like something within him unlocks. The feeling doesn't go away, and each time it strengthens. Genos comes to live with him, and it's as if something clicks into place.

Day after day, the feeling grows stronger, and one day he realizes that he knows what Genos is feeling. He can sense it, that's the only word for it. Later, the thoughts come pouring in.

One day, he turns over to Genos while they're sitting together in the quiet, and he softly kisses Genos. Genos stares at him, and the memories come pouring in.

It is as if he has lived his life in darkness, and one day, he lifts the blinds, and he sees again. His world is bright again.

"Master," Genos says, and Saitama laughs. He has found his Prince again. One more lifetime together, and more forever.

"Genos," he whispers and he kisses him again.

"Genos," he says and he arches his back. Genos sucks on his cock, and his eyelashes flutter as he looks at Saitama. Saitama bites on his fist, trying to last. Genos' mouth is hot, and his tongue flicks on the slit. He sucks ever so gently, and heat runs down all the way to his groin as he jerks into Genos' mouth.

Saitama wishes he could bite Genos all over like he did before. He wonders if he can convince Dr Kuseno to give him skin-like texture all over his body. Genos pulls away and Saitama whines. Genos only smiles and turns Saitama forcefully. That display of strength shouldn't turn Saitama on so much but he is, his cock full and heavy.

Genos places him on all fours, and Saitama arches back and immediately moans when Genos licks experimentally. He traces his tongue around Saitama's entrance, and Saitama tries not to push back. He feels so very warm, and Genos is not helping. He's slowly swirling his tongue around, his fake saliva dripping down to the sheets. Saitama's trembling, and he's whining now as Genos gives him steady, long licks.

He wants more. He wants so much more. He wants Genos to fuck him hard and fast. Genos pulls away, and Saitama's about to yell at him when his finger slides in smoothly, and Saitama lets out a groan. Genos' fingers are slightly cold, and rocks back against the rhythm that Genos sets. He pushes in two.

"Master," Genos says, and his voice is choked on emotion, "You're so tight, and it's hot, oh."

"I can take it, I- I won't break," Saitama says, and Genos slides in a third finger. Fuck, it's a stretch. "Oh, oh, Ge-Genos!" His elbows slide down, and he can't support his body anymore. Saitama has to turn his face to the side to breathe through it.

Genos runs a hand down his side, and he's whispering filthy things that's echoing around their apartment, and Saitama's about to melt into a puddle. Genos pushes his thighs further apart, and he's moving his fingers up and down. He crooks them, and Saitama lets out a scream. "Fuck!"

"Ah, Genos!"

"You're doing so well Master, so good," Genos says, and he's babbling but Saitama doesn't care. He's pushing against Genos' fingers. Saitama presses his elbows on the bed, and he pushes himself up, his back arching.

Genos pulls out a finger, and Saitama's shivering with excitement now. He pushes in slowly, and it's a stretch. Saitama bites his lips. He wants Genos to ram into him hard, but he know Genos wouldn't do so for fear of hurting him. Even now he's forcing himself to breathe, to not tense up. His cock is warm, and Saitama knows that Genos is letting a little of his power to make it hot enough that it isn't uncomfortable.

Even when fucking Saitama, Genos is still trying to be considerate. Saitama's planning for a time when he can wreck Genos that he won't even remember his name.

Genos is slow, oh so slow. He's working Saitama loose with short, sharp thrusts, sliding in and out, over and over again.

"Please Genos," he mumbles out. "Please!"

"Beg for it," Genos whispers, his voice low, and he nuzzles into Saitama's neck. He scrapes his teeth along the muscles of Saitama's shoulder.

"Fuck me hard, pl-please Genos!"

"As you wish Master," Genos purrs, and thrusts in harder. The heavy slap of Genos' hips against Saitama's ass is covered by Genos' heavy breathing and Saitama's moans. He's mewling now as Genos keeps sliding over his prostate. Saitama's overwhelmed with the pleasure and he can feel tears leaking out of his eyes, his mouth is wide and he's drooling, his mouth seeking something to suck and to bite as Genos continues to fuck into him hard, just the way he wants it.

"Master, come for me," Genos says, and bites down his neck, drawing blood. Saitama lets out a shocked cry, and comes. He clenches around Genos' cock, as his come shoots out across his stomach, and Genos lets out a groan. He pulls out when he comes, shooting it over Saitama's back in hot wet drops.

Saitama reaches back and his scoops it up with his fingers, putting them in his mouth, tasting Genos' cum. He moans around his fingers, and though he feels each skin tingling, wanting more of Genos' touch.

Between them the bond is strengthened yet again, and he can feel Genos' emotions through it.

Love. Joy. Giddiness.

Saitama's drunk on pleasure, and the power of the bond. It's consuming him, surrounding him, and everything else that he has experienced pales in comparison to the encompassing enormity of this moment. He pulls Genos close, and he kisses him, wet, sloppy, deep.

"Another world to save," he says when he can breathe again. "Another life to live with my Prince."

"Forever," Genos says, and he kisses Saitama's right hand.

In each cycle, in every lifetime, the Prince and the Knight shall meet.

The bond between them will burn, and it shall be so till the end of the world.
