My housemate Daniel, was one of those “geek chic” types who was both nerdy and fashionable at the same time. He was intelligent, thoughtful, bookish, yet attractive and popular. God, I hated him.

Eventually I’d had enough of all the pompous intellectual crap, so I dusted off my potion recipe book. He was obsessed with drinking coffee, so I made him a jar of very special “coffee” for his birthday. I pretended that it had come directly from Java, not from the cauldron in my bedroom where it had really come from. I called it “Duhmjoch”.

The changes were slow at first, and I wasn’t sure if it was working or not. Then one day I found him sitting on the sofa, watching a football match instead of the usual boring documentaries he liked to watch about Van Gogh or some shit. He claimed that he was watching the football “ironically“. I just smirked and said, “Yeah, sure.”

Things started to speed up after that, and I noticed changes in the way he looked too. He came home one day with shaved hair, and with his glasses replaced by contact lenses. I had to double take. He said he just fancied a change.

That same week he decided to start going to the gym, making some excuse about wanting to get rid of belly fat. He was so skinny back then, he didn’t need to lose any weight, and we both knew it. After that, he spent so much time at the gym, I barely ever saw him. Every time I did catch him in-between workouts, I couldn’t help but notice how less and less skinny he was becoming. The most shocking change was the day he came home with his first tattoo. I could barely believe it. Back in his coffee shop days, he had always droned on about how tattoos “disgusted” him, but now he was proudly showing one off in front of me.

“The guys at the gym said this was dope,” he said, flexing his newly inked bicep in my face.

When I realised that he had stopped drinking coffee, maybe I should have stopped there too. The problem was I was enjoying seeing the changes in him so much, I couldn’t help myself. So I started spiking his sports drinks instead. Things escalated from there.

Six weeks later, I came home to find him standing semi-naked in the kitchen, looking confused. I stood silently in the doorway for a moment, admiring my handiwork.

He turned to look at me with a blank expression on his face – a face that was now so much more masculine and angular that it had once been, made even sexier by his street hair cut and ear studs. I couldn’t stop my eyes from drifting down towards his now heavily tattooed and muscular torso, and then down to his black skinny jeans which were stretched tight around his newly muscular legs.

“Have you seen my phone, bro?” he asked me with his recently developed deep voice.

“You’re holding it,” I responded.

“Ah yeah!” he exclaimed, realising his mistake. “Thanks bro, you’re the best...for a geek!” He laughed and then slapped me hard on the shoulder.

What had I created?

A few weeks later, I found him standing in front of the mirror in the spare bedroom, silently staring at his own studly reflection. He looked almost hypnotised. The old Daniel had bought the mirror from an antiques shop with the intention of redecorating the spare room into some kind of “snug” as he had called it. All those plans had evaporated after I started feeding him the coffee.

“Hey Dan, are you OK?” I asked – he preferred to be called “Dan” now.

He turned and looked at me.

“Did you do this to me?” he asked.

“Um, did I do what to you?” I asked, shuffling my feet nervously.

He looked back at his own reflection again. “I didn’t used to be like this,” he said. “I used to be different. I don’t really remember it very well anymore, but I saw some old pictures today, and I look so different...so different.”

“Well, you know,” I said with a nervous chuckle, “people change all the time. They find new interests, meet new people, it’s normal.”

“This isn’t normal,” he said plainly. “Also, I went into your room and found all your magic books and weird shit.”

“How dare you go into my room!” I roared, suddenly furious. “Those are my personal things!”

He turned towards me and took a step forward. His powerful body and masculine face were imposing now, intimidating even. “So, did you do it?” he asked.

“And what if I did?!” I found myself blurting.

He suddenly grabbed me firmly by the shoulders and thrust me up against the bedroom wall. I was powerless to resist against his huge tattooed arms. I didn’t want to resist.

“In that case,” he said, aggressively moving his face towards mine, “I just wanted to say...thank you.”

And then he planted a huge kiss on my lips, before laughing and striding out of the room, leaving me frozen against the wall with an astonished expression on my face.

After I finally managed to unfreeze myself, I cautiously crept down the stairs and into the living room, where I found Dan casually relaxing on the sofa, watching TV.

I sat quietly on the carpet in front of him and we looked at each other. His thick muscular legs were splayed out in a way that made me want to melt.

“So, you’re not mad with me?” I asked.

“Why would I be mad, bro?” he laughed. “I’ve got fucking muscles now!”

He arrogantly then flexed and licked his own bicep right in front of me. I almost fainted.

“But, you always hated muscle jocks, and gyms, and tattoos, and all that,” I said.

“That’s because I was a pompous twat,” he said. “I’m a man now. A proper man, and I love it.”

“Yes, you are,” I said honestly.

“I’ve noticed how you keep looking at me,” he said, starting to pull down his shorts. “I might not be as smart as I used to be, but I’m smart enough. Want to see more?”

“But, I thought you liked girls?” I said with confusion.

“I just like to be worshipped,” he replied as he pulled his cock out.

I didn’t need to be asked twice. I crawled forward and took his masculine meat into my mouth.

From that day on, Dan was the man of the house, and I was his happy and obedient servant. To satisfy him, I started using magic on myself to make me even more obedient, even more his perfect servant, until eventually neither of us resembled our former selves.

We had the perfect relationship, and I loved every second of it.
