Results

Two important things happened over the weekend after the Exorcist Qualification Exam: Rin's horns sprouted, and then while he was suffering through the splitting migraine it gave him, his results came back from the Exam.

Mephisto waited until the horns were fully sprouted and the pain subsided some to tell him. He actually told Rin as he was leading the teen to his Master Bath to wash the blood off of him, along with the sweat.

"Your results came in, Dearest. I believed you would like to open them with your friends, so I took the liberty of inviting them for a semi-formal dinner party at 7." Mephisto mentioned casually.

"Great." Rin was currently too exhausted to be super excited and Mephisto seemed to understand that. Hopefully washing up would revive him somewhat. Or Mephisto could do that himself.

He turned on the bathwater and got it to the right temperature and while the tub was filling up, he turned the shower on and switched the setting to gentle cleanse. Rin would be very sensitive so soon after his horns grew in completely.

He ran warm water over the blood and sweat from the several hours of being in pain and writhing in the sheets of his bed while keratin pushed through his forehead and new nerves grew to extend inside said keratin. Rin's horns were a glossy black now, but while they grew in, they'd been glowing the same blue as his flames.

The horns grew out from his forehead just behind his hair line and curved back, over his head. They seemed like a more defensive asset than offensive and that suited Rin quite well. They would protect Rin's head if anything or anyone landed a blow there, though it would hurt with the nerves in the horns.

Mephisto gently washed away all the filth, lightly scrubbing with a loufa instead of a washcloth. Rin would be very sensitive. Mephisto could already see his reaction just looking at Rin's tail. It waved around and paused a lot, conflicted as Rin fought to sit still. He couldn't, he ended up squirming on his stool and Mephisto chuckled. "It's alright, Dearest. We have plenty of time before dinner. You should relax now. Let me take care of you." The same words from that time during Rin's etiquette lessons months ago.

Mephisto slid his hands down the Nephilim's chest to between his legs and rubbed a finger along the slit there. He quite liked Rin's new anatomy. High-level demons like the Demon Kings could all chose what kind of body they wanted to have when in physical form.

Mephisto and Amaimon both chose external genitalia mostly because they both had manners and could actually keep it in their pants and they both liked to do risky things in risky places sometimes. But Rin had chosen to have internal genitalia, which made coaxing him into full arousal even more fun.

Rin whimpered and grabbed the Time Lord's wrist-not stopping the movements of his hand, just holding it to ground himself. Mephisto purred and kissed Rin's neck lightly, adding more force to his rubbing. He could feel Rin's body getting hotter and the teen squirmed more in his seat.

"Mephi~!" Rin keened quietly. The Demon King grinned against his neck and sunk a finger in to the third knuckle. Rin gave a surprised cry, arching at the intrusion. Inside, he was slick and hot and soft. Mephisto rubbed Rin's walls with the pad of his finger and the boy squirmed in place. This was a new experience to him.

The Demon King slowly added two more fingers until he coaxed Rin's dick out and stroked it with his tail. He kept thrusting his fingers into the slit, holding on to the barely coherent Rin. Pleasant shockwaves of pleasure were trying his oversensitized body.

Mephisto moved one hand to thumb the base of one of Rin's horns and the boy trembled in his arms. It sent shocks of pleasure-pain cascading down his spine and he arched his body as Mephisto bit down on his neck and licked the blood from the fang sounds.
