His fingers are gentle even as the rope tightens around his wrist. It's silk and it does not chafe, but it presses into his skin nonetheless and will leave a mark by the time they are done. The susurration of fabric against his skin makes his spine tingle in anticipation.

The movements above him are deliberate in their intensity and precision and by the time all the cords are tight, Frankenstein is more than a little hard. Breathless and straining. Red eyes flicker to his, questioning, and Frankenstein has to remember how to reassure his Master mentally.

He's not allowed to speak, after all. What with a gag in his mouth and all.

But that is something he has requested himself, just so Raizel cannot blame himself. Besides, their mental link functions better than vocal communication and he can transmit everything he feels to his Master, offering and surrendering every last bit of desire and pleasure to his feet.

For his consumption, only to be devoured in turn by his own.

Raizel does not speak either as he unbuttons Frankenstein's clothes. Parts them with his hand and traces the contours and ridges of Frankenstein's chest, tracing all the ribs and hard muscle of his abdomen. He wants those fingers on his chest, he wants them to put clamps on his nipples to see if pain excites him, when caused by these hands, but he refrains.

Raizel climbs over him, resting his weight on Frankenstein's lap and presses warm kisses to his neck, nipping and soothing alternatively with his teeth and tongue. The air grows thin around Frankenstein, making it hard to draw breath and his vision darkens. The bonds that hold him down cut into his flesh as he bucks up, wanting more contact but not allowed to ask. Or beg. All he can do is silently plead with his Master to give him more.

And he is denied.

Because that is how it is supposed to be, and his Master understands. He'll give Frankenstein what he needs, all in due time. He brushes away Frankenstein's impatience in his mind and marks his neck with soft bites, enjoying himself to the fullest. His pleasure mounts, albeit not as fast as he'd like, as his Master lavishes attention to every part of him. Their souls brush together, touching everywhere, so it's no wonder that his Master wants to recreate the experience in flesh.

It only stops being endearing when that graceful mouth descends upon his erection, those sharp teeth hidden away somehow and that tongue pressed against the underside of his cock. For a moment, Frankenstein is afraid that he has broken through the bonds and gotten up. A hand reaches out then, holding him in place, calming him despite the pleasure that threatens to burst at the seams.

Frankenstein spends all his energy on breathing, in and out, through his nose as his mouth is stuffed with a silken handkerchief, serving as a gag. He regrets, for a moment, asking for it because he wants to cry out his pleasure, let it out somehow or else he'll – he will...

Raizel lets go of him, making Frankenstein let out a stifled groan of displeasure and within moments, concerned claret eyes boring into his and Frankenstein remembers the terms of their arrangement. He closes his eyes and reaches deep inside, following the link of their bond that connects them so, and shows how he feels to Raizel. He does not regret the gag, not really, but the inability to vocalise the sensations wracking through his body has him overwhelmed.

Elegant fingers pry the cloth from his mouth and he takes a deep, shuddering breath. Because this is his Master, he knows how to walk the fine line between what Frankenstein says he wants and what he truly wants. Master takes great pains to understand everything Frankenstein says or does, gauging from verbal and non-verbal communication as to what he desires at an exact moment.

There are no words to describe how cherished it makes him feel.

"Forgive me, Master, I – "

Raizel shakes his head, cutting him off and resumes his ministrations, robbing Frankenstein of his contrition and higher reasoning abilities in one fell swoop. But it's all right, not like he really needed those things anyway.
