Happy Friday the 13th! Last Friday, I introduced you to Professor Pain, a supervillain who was commissioned by a superhero to find a way to cause him BDSM-related pain. Here’s the conclusion.

***

It took a month of careful experimentation and another month of detail work, but finally Professor Pain was ready to demonstrate what he’d come up with. Even though he didn’t have a secret lair anymore, he did still have a basement in his home in the suburbs, half of which was a workshop with all his tools of the trade, and the other half of which was a dungeon space. He’d messaged the Unstoppable Force on a Monday morning, and he’d shown up that very night.

“Can I get you a drink or anything?” the professor offered after allowing the superhero into the house.

The Unstoppable Force shook his head. “Honestly,” he said, his voice soft, “from the moment you messaged me all I could think about was what you had in store.”

Professor Pain nodded. “Follow me.”

He led the superhero down to the dungeon space. Within the wood-paneled walls were a spanking bench, a Saint Andrews cross, a hard point in the ceiling, and shelves upon shelves of the professor’s personal toy collection.

None of which he’d be using tonight.

“Take off your clothes,” Professor Pain said.

“Yes, sir.” Holy shit! Was this really happening? “But the mask stays on.”

“Fair enough.”

Soon, the Unstoppable Force was naked in the middle of the room. He had a good body — not too muscular, since his powers came from meteor radiation and not the gym — and Professor Pain couldn’t help but glance at the superhero’s cock, which was half-hard and pleasantly-shaped.

Professor Pain unfolded a tray table and set a lead-lined case on it. When he opened it, a faint green gleam made his heart start to beat faster. It always did when he was about to play with someone new.

The professor took out each item and showed it to the Unstoppable Force. There was a pair of matched floggers treated with a solution made from the meteor disc, a paddle with specks of it embedded in the wood, and Professor Pain’s personal favorite: a pair of fingerless gloves shot through with threads of meteor material. He pulled these onto his hands. “You ready?”

“Oh, yes. Yes, sir.”

Professor Pain pointed to the spanking bench. “Over,” he said.

The Unstoppable Force knelt on the bench’s padded surface and bent over, his bare backside raised. Professor Pain moved close to him, one hand on his lower back, and with the other he caressed the superhero’s ass. The Unstoppable Force shuddered. “I felt that,” he said, his voice full of wonder. “I actually felt that.”

“Good.”

Then, without warning, Professor Pain smacked the Unstoppable Force’s ass.

Hard.

The superhero grunted and shifted.

Another smack.

And another.

And more.

More.

More.

Professor Pain’s favorite implements were his hands, and over the course of the next half-hour, he used them to great effect. He spanked the Unstoppable Force until the superhero’s ass was bright red; he slapped and punched his shoulders; he dragged his palms along the Unstoppable Force’s back, leaving smears of pink and red as the meteor material in the gloves touched bare skin. And, all the while, he tried to avoid thinking about how turned on he was, not only because he was indulging his sadistic side, but also because he was blown away by the fact that he was this close to a superhero and wasn’t about to be thrown in jail. It was exciting.

Eventually the Unstoppable Force was gasping for breath, moaning with each spank, which Professor Pain was driving into his ass at full strength. Bruises were starting to form low on the superhero’s backside, and the professor’s arms were starting to get tired.

Not that he would ever say that. Instead he said, “I think we should stop for now. I don’t want to do too much our first time.” He stood behind the superhero, holding his hips, and then took his shot, leaning forward until the Unstoppable Force couldn’t fail to feel the professor’s erection through his pants, pressing up against his warm backside. “Unless you want more?”

“Fuck yes,” the superhero breathed. “Fuck. Yes.”

Well, that was encouraging. Professor Pain reached between their bodies and found the Unstoppable Force’s cock. It was mostly hard, but as he wrapped his gloved hand around it, it grew to full strength. He started to stroke it, and the superhero sighed happily. “That feels so fucking good,” he said.

“Does your girlfriend not do this for you?” the professor asked.

“She does, but…” The superhero shuddered. “She can’t hurt me. This… this hurts. It feels good, but it hurts too.”

Well, now, that was a revelation.

Professor Pain slapped the Unstoppable Force’s ass. “Turn over,” he said.

Just like any other bottom, when the Unstoppable Force’s bruised backside met the padding of the spanking bench, he hissed and squirmed. But his cock remained hard, which was what Professor Pain wanted. He knelt in front of the superhero, took hold of the base of his cock, and dipped his head. Before long he was sucking the Unstoppable Force’s cock in earnest, and the superhero had his hands in the professor’s hair, not really guiding him so much as telling him with little flutters of his fingers how good he was feeling. It probably helped that the professor was holding the Unstoppable Force’s balls gently in one gloved hand, squeezing ever so slightly as he took the superhero’s cock into his throat, his nose pressed into the hair at the base.

“Fuck!”

Professor Pain pulled back and gasped down a deep breath, pleased with himself — maybe the Unstoppable Force’s famous girlfriend wasn’t so good at giving head? Or maybe it was the pain that made it better? The professor didn’t know; all he knew was that he’d just beaten a superhero, and now he had him just where he wanted him: hard and sore.

He looked up at the Unstoppable Force. “Have you ever fucked anyone in the ass?”

A slight nod. “A few times. Before… well, before.”

“Good. That means you know what to do.” Professor Pain got to his feet and unbuckled his pants, letting them and his briefs fall to the floor. He stepped out of them and kicked them aside, and then took hold of his own cock. He stroked it slowly. It wasn’t as thick as the superhero’s, but it was longer, and he saw the Unstoppable Force’s eyes widen. “Don’t worry,” he said, “when it comes to sex, I’m a bottom, not a top.”

“Oh.” There was relief there; was the superhero really afraid of having his own ass fucked?

It didn’t really matter, though. Professor Pain retrieved a condom and some lube from one of the shelves, and then knelt on the carpeted floor on his knees and elbows, his own ass in the air. “Fuck me,” he told the Unstoppable Force. “Be a good boy and fuck me.”

“Yes, sir.” It seemed as though the superhero responded well to being ordered around. This had promise.

Professor Pain closed his eyes and listened to the sound of the condom being opened and then the squelching that was undoubtedly the superhero spreading lube onto it. He felt some of it drip between the cheeks of his ass, but instead of using his fingers, the Unstoppable Force knee-shuffled closer.

Okay. Fine. If that was how he wanted it. It had been a while since Professor Pain had been fucked by a man, and he didn’t mind feeling stretched out.

The professor felt the thick head of the superhero’s cock nosing at his opening and he clenched his teeth. He took a deep breath and, as the Unstoppable Force pushed forward, he let it out slowly, his body accepting the superhero more readily than he’d thought it would. Before too long, the Unstoppable Force was buried to the hilt in Professor Pain’s ass. “Good boy,” he said — growled, really. “That feels amazing.”

“Uh-huh.” Oh, the professor knew that sound — it was the sound of someone so overwhelmed by either pleasure or the situation that he didn’t know what to do or say.

Fortunately, Professor Pain had plenty of experience at this. “Fuck me,” he ordered.

He felt the superhero’s hands on his hips; his fingers dug in hard, more painfully than the professor might have liked. But he was about to get fucked, so he didn’t mind.

And, as he learned quickly, the Unstoppable Force knew how to fuck.

Hard.

Harder than the professor had been fucked in a good, long time.

“I can’t come inside you,” the Unstoppable Force said after one particularly deep thrust. “I don’t want to hurt you.”

Professor Pain considered this. If all of the superhero’s muscles were augmented by the meteor radiation, it made sense that the muscles involved in orgasm were as well. The last thing he wanted was to have his insides shredded by a super-orgasm.

Fortunately, he had options. “Sit down,” he told the superhero.

It wasn’t comfortable to feel the Unstoppable Force’s cock fully exiting his ass, but the Professor knew that was a part of anal sex and he’d come to accept it. While the superhero sat back down on the bench, the professor pulled off his shirt and knelt in front of him. He stripped away the condom and took hold of the superhero’s cock, using the meteor-infused glove. The Unstoppable Force moaned and thrust against the professor’s hand as he stroked him, the blunt head of his cock pointed directly at the professor’s chest.

Even with the glove on, the Unstoppable Force’s orgasm was powerful, splattering thick, hot streams of come against the professor’s skin, each one feeling like the thump of a fist on a door. It hurt, yes, but it felt amazing too; he’d always liked when his partners came on him. And there was a hell of a lot of it; Professor Pain wondered how long it had been for the superhero.

When the Unstoppable Force was done, he slumped back against the spanking bench, chest heaving, his cock becoming less erect in the professor’s gloved hand. “That was wonderful,” the professor said. “You’re such a good boy.”

“Thank you, sir,” the superhero said between gasps for air.

“My turn now.”

The Unstoppable Force’s eyes widened in his mask as Professor Pain got to his feet and tossed his gloves aside. He swiped his bare hand over his chest, smearing the come into his skin even as he collected some of it in his hand. Then he took hold of his cock and started to stroke himself. He was already halfway there, between the hard fucking and the come on his chest, and although he’d have enjoyed fucking the superhero’s mouth until he lost control and came down his throat, he didn’t think the Unstoppable Force was ready for that yet. It was, after all, his first time with another man.

So the professor did it himself, and as his orgasm hit he aimed his cock upward so the spurts landed on the Unstoppable Force’s white-and-red mask. Even though he wasn’t a supervillain anymore, the very idea of marking the superhero like this made him want to unleash his evil laugh, the laugh he hadn’t done since he’d retired. He resisted the urge, though, and just looked down at the superhero, at the come dripping off his mask and face. “Good boy,” he said. “Did you like that?”

What little of the Unstoppable Force’s face the professor could see around the mask flushed red as he nodded.

“And you’ll want to do it again, I trust?”

Another nod. “Yes, sir.” The superhero’s tone made things quite clear: he might not necessarily be bisexual, but he was beyond happy to have submitted to Professor Pain.

“Good boy,” he said. “Now, let’s clean up.”

Later that week, while exercising on his elliptical, Professor Pain’s phone vibrated. He checked the screen; it was a picture of the Unstoppable Force dedicating the new wing of a hospital. The superhero’s face was kind and strong under his mask, the picture of dedication to the forces of good.

But all Professor Pain could see was the superhero’s mask and face decorated with his come.

He smiled.

“Good boy.”

The End

I’m not sure if I’m going to do anything more with these characters, but I have to imagine that if the Unstoppable Force lets it get around that Professor Pain can help with BDSM for superheroes, he could get all sorts of commissions. I guess we’ll see.
