His breath stops in his throat at the sensation of his master striking him. Groaning, he rocks back, savoring the sting travelling down his thighs and up his spine. "Thank you, Master," he breathes.
Master strikes him again, and he jolts. "Thank you."
"Thank you."
"Thank you."
"Thank you."
He moans at the next one, his thighs trembling. He doesn't know how much longer he can keep himself supported. His cock twitches, wanting. "Thank-Thank you," he whispers.
Master strikes only hard enough for him to feel just enough pain to excite him, though not as much as he is generally accustomed to in battle. They are different kinds of thrills.
His flesh must be red by now. He feels Master's fingers dig into his hips, pulling him closer so that Master's own presses warmly against him. "Are you satisfied, Frankenstein?" That voice is gentle and glides cooly over his heated body.
"...No," Frankenstein admits. "Harder, Master, more."
Raizel looks down at him with concern, his brows knitting slightly. "You are certain?" he asks as he soothingly carresses Frankenstein's flesh, on the verge of bruising.
"Yes, Master." Frankenstein swallows. "Punish me, for everything, show me I'm yours. Make me cum, just like this, then take me for yourself."
"As you wish," Raizel whispers in his hair, his hand snaking around to grasp at Frankenstein, stroking him a few times before straightening once again. He raises his hand, and it descends swiftly, like judgment, like fire.
Frankenstein gasps, his fingers curling around the linen, bunching it. "Thank you," his words are full of air. A sound, a flash of pain, and Frankenstein calls out. His thighs and core are tense, his hips involentarily rocking, seeking some sort of relieving contact; it is wet between his legs.
The next one feels like bursting firecrackers and he is hot and trembling. "Thank-" Master does not wait for him to finish before he strikes him again, sending him over the edge, toppling him. Frankenstein's chest heaves and he shivers, coming hard, clutching at the sheets and contracting, making a mess of the bed beneath him. He gasps for breath when he feels Master abruptly press into him. A moan; he feels like melting. "Thank you, Master," he says, voice dreamy and a little hoarse. "Thank you..."
He does not stop thanking him for the rest of the night.
