A bit about me in a moment. I want to begin this story with complete transparency from the beginning.

My name is Luke.

I’ve been working on a recipe. Well, if you believe in Western medicine, it’s a recipe. If you’re more mystical, then it’s an elixir. If you’re into wizardry, then it’s probably more of a potion.

Either way, I’ve been having quite some success with it. This was part of my supplementation research that I go into later in this story.

Its origins are part folklore, part Google search, part library research, and then idle time to contemplate and consider.

You see, by way of folklore, I’d been told of a plant that is so potent that it effectively amplifies your neurological function. In lay terms, it turns your conscious thought into a physiological manifestation. These are sanshools. They create a distinctive tingling or buzzing sensation when taken on their own. I’ve found that the best available source of these is the humble Szechuan pepper. Its effect was, unfortunately, always weak and short-lived.

The next challenge for me was to amplify this effect for a stronger reaction. Through a process of elimination from my own research, web browsing, and chat forums, I ended up stumbling across a rare as fuck plant that lives in one of the distant corners of the earth. South of the Australian mainland is an island called Tasmania. In a few south-western areas of the remote old-growth forest is an ugly bush called the Tasmanian pepperberry. It has a polygodial oil that magnified the effect when combined with the Szechuan.

It created an incredibly strong tingling sensation—the same as the Szechuan did for the mind, but with the pepperberry, it was magnified and had the same effect on my sexual functioning.

In short, it made me horny. Very fucking horny. It gave me erections so strong that my cock felt like it was going to burst, such was the blood flow pumping into my shaft. My whole groin tingled with the sensation of being plugged into a battery.

Still short-lived, I started the quest to lengthen the time of the effect. For that, I realized, I was going to need ferric citrate. That would have the effect of drawing out the catalyst reaction longer. Unfortunately, you can’t just buy a bottle of it and be on your way home.

The best source I could find, and one that would allow this to be palatable, would be a strange soft drink whose origin lay in the highlands of Scotland. Irn-Bru, the orange fizzy drink known as Scotland’s other drink (after whiskey), is the best natural source.

I’d combined these into a paste but hadn’t tried it as of the start of this story as outlined below. Thanks for hearing me out to this point. Let the story continue!

I’d often wondered if my parents were pleased or secretly bemoaned my chosen career path. I’d had the intellect to study at the college level but not really the patience. After high school, I was encouraged towards further education. School counsellors, relatives, and teachers all said essentially the same thing, which most people hear at the same stage of life. I’d always loved the outdoors and physical activity, so their gentle thoughts were politely stored in the backend of my brain and consciousness.

I’d taken up work in the landscape business. Those who’d encouraged me elsewhere used the phrase, “He’s fallen into landscaping." "I'd thought that had some negative connotations. I loved my job. We didn’t mow lawns; nah, our work was deep-level, thoughtful design aimed at a boutique level of customers.

I was twenty years old, halfway through my training.

The shock of not having summer off had been a rude introduction after school had finished, but now I was in the swing of it. I’d arranged to take some leave to visit my folks back in our hometown while my sister finished off her last year at high school. Ella, my younger sister, was well and truly on the path for college. She had my academic ability, combined with a calm sense of direction that I didn't have. She was eighteen and destined for a college to study biomedical science.

Our parents lived in an estate with large blocks with sweeping views of the rolling hills to one side and a large bay out the front. Further afield, the Pacific Ocean called us forth with its majesty. The dramatic coastline told a different story each day, from warm and welcoming on a spring afternoon when the water was crystal clear with a beautiful glassy surface.

Fifteen minutes away, Drakes and North Beach often gave me two-foot waves as they were peeling in off the headland. On other days, it was cold, abrasive, and hostile. A dark, windswept evening with storm clouds could literally dictate the mood in our house.
Point Reyes was a gorgeous part of the earth. Unfortunately, it just wasn’t big enough for what I wanted, and for that matter, what Ella wanted. Perhaps in the future we’d all reconvene permanently, but for now it was our last break together before my sister left our parents without anyone besides themselves.
Ella had invited a few of her friends to stay at our place for a couple of nights. We were one of the families that had a backyard pool that looked over the bay. Not quite an infinity pool but pretty close. A large cabana separated the house from the pool, which looked out over the bay, with our brush fencing offering privacy to those in the water while also allowing panoramic views to those who stood on the pool deck.

When I’d left home to start work, I was a spindly teen. No muscle mass to speak of, no hairstyle to speak of, and a level of confidence that asked for permission to ask permission. When I started work away from home, workmates had introduced me to the gym. I found that I gained solace there—the long wait for improvement caught my attention. I’d become regimented in my workouts, and, combined with my physically demanding work, I’d put on some twenty-five pounds in muscle.

Exercise, nutrition, supplementation, and recovery had all become a part of my everyday life. The supplementation had become an area of significant interest to me—but a little more on that later on.

Due to me frequently working on worksites with those who work on worksites and my changing body shape, I’d found that my self-confidence had grown somewhat. Gone was the nervous skinny teen, and in his place was a proud, positive, and friendly guy with plenty of friends and an otherwise healthy social and romantic life.

Now, as I stood here in my childhood backyard, I couldn’t help but contemplate the changes that I’d undergone. The same place has a way of drawing nostalgic feelings—I had to fight to stop feeling like that nervous teen that had left a short couple of years ago.

From behind, a large splash startled me. Ella had deliberately snuck up on me and drenched me as she bombed into the pool. Her friends all giggled as she surfaced.

“You’re about as funny as a fart in an elevator.” I quipped at her as I wiped off some of the water from my shirt.
She’d changed as well. Gone was the fringe, and she filled her bikini well. Really well. She wore a light blue top and bottom with yellow straps around her shoulders and waist. Against her skin, the colours popped. The waist sat low over her hips, and her top was full and proud. Her friends were all in similar attire as they slipped into the warm water.

I had to force myself to turn away—my main reason for being out here was to look over the coastline and to see if Mrs. Sullivan was about.

Claire and Andrew Sullivan had been our neighbors for the previous ten or so years. They’d moved to set up practice. Andrew was an environmental scientist who worked on a consultation basis.

Claire had originally been a massage therapist but had pivoted into training as a physical therapist while I was in high school. I’d always been aware of her. She was, in my mind, the original MILF, even though she had no children.

Claire would have been about fifteen or so years older than me. I’d secretly always admired her. She was polite and friendly and oh so attractive. She had long blonde hair that fell about halfway down her back. She generally had it pulled into a simple ponytail.

Our backyard looked slightly down on theirs. The large blocks we lived on afforded privacy due to the size of them, but we could still see them as they went about their lives. Claire had a wonderfully athletic build—she was lean and toned with a body that endured a life of sideways glances from men and fleeting jealous looks from envious women.

I’d see her out running every now and then and always marvelled how nothing seemed to bounce. She’d smile and wave to my parents as she effortlessly glided by. I’d seen her in her swimwear from time to time—almost always in a simple one-piece designed for swimming laps. The one time I’d seen her in a bikini, I made myself take a mental photograph that I could hold on to—that had been just after I’d finished high school.

No one knew how I viewed Claire. My parents had told us that they thought they were fairly religious and had wondered out loud that if that were the case, why didn't they have any children? Nevertheless, they’d lived their life, and we ours.

The nostalgia washed over me once again as I took in the smells and sounds of home.
Behind me, Ella and her friends Kate, Lily, and Rebecca all lazed in the sun on the pool deck. I turned to make my way inside and was confronted with four bikini-clad female bodies. I had to admit to myself that each one of them was gorgeous. Deep down I acknowledged to myself that Ella was probably the most attractive of them. Not that I’d admit it aloud.

"Damn!” I exclaimed as I briefly took in the sight in front of me. As I wandered past, I couldn’t help but notice eyes follow me.

“Hey, Mom,” I called out. “I’m heading out for a run. I’ll be twenty minutes or so.”

“Ok, see you soon,” came her reply.

I’d wanted to jog down to the bayside and along the water on my old route. As I ran along the undulated path near the water, the growth along the banks had the smells and sounds I’d missed. Large leaves were swept to the side as I brushed them with my shoulder, while the tall timbers further back told of their age due to their sheer size. On the water, a few boats were dotted along the shore, with a couple further out either fishing or skiing.

I was so caught up in the moment that I didn’t see a two-inch tree root that was lying across the trail. I caught my toe on it and tumbled down, falling on my right shoulder.

“Fuck!” I cursed myself. Dusting off the moist dirt, I tested the range of motion around my shoulder. It didn’t seem too bad, so I continued. The ninety-degree day had me sweating well and truly by the time I got home.

As I walked inside, my mother spotted my shirt, covered in the dirt from my excursion to the ground.

“Ow! Luke! Are you ok?”

“Yeah.” I said, starting to strip off my shirt. “Just tripped over and landed on my shoulder.” I needed a swim, the humidity had risen as fast as the temperature.

I headed to my bedroom, tossing the shirt in the laundry on my way. I pulled on some swim trunks and headed to the pool, not stopping until I dropped into the deep end. The wave of relief washed over me as the water washed the sweat away.

Ella and her friends were still around the pool. I waded over to the opposite side of the pool to them and hoisted myself up on the edge, facing them. She looked up from her phone.

“Missed your chance to get me back." She muttered, looking me up and down through her sunglasses.

Her friends did the same. To be fair, they were all attractive.

Kate, Lily, and Rebecca.

Rebecca was of Italian descent with dark features, almond-brown eyes, gorgeous hair, and a stunning smile and body. She wore a tight white t-shirt over a yellow bikini top and bottom that I could see through the t-shirt.

Lily had an amazing body that neared Ella’s. She wore a block-red swimsuit that fit her gorgeous form perfectly. Her outline was something from a teenager’s dream.

Kate possessed the best ass on the planet as far as I was concerned. She was wearing a blue and white bikini set with a small, printed pattern and a pair of tight shorts.

I caught Kate taking in more than a casual glance. She was looking me up and down through her mirrored glasses. Something about how she held her mouth was different.

The water sheened my skin, rolling down over my chest and six-pack. From my peripheral vision, I thought I saw Rebecca tap Lily on the leg.

“What are you lot up to tonight?” I asked.

“Nothing,” Ella replied, rolling on to her side to face Kate. “Just going to stay in and watch a movie.”

Kate rolled to face my sister. Her bust fell onto her right side and squeezed together as it rested against her shoulder.

I’d had enough. I was going to my bedroom to jerk off. It’d been weeks. There was too much flesh on offer out here. Besides, I had a new mixture I wanted to try.

I climbed out and wrapped a towel around my waist. As I made my way past Ella and her friends, I could feel the eyes follow me again.

“See you later, Luke." Lily looked up at me and smiled. The others all tried to contain a smile as I returned her salutation.

In my room, I stripped off my towel and let it fall to the ground. In my suitcase, I brought out the mixture. It was a paste-like consistency and smelled sweet since the addition of the Irn-Bru.

I too dabbed and dropped my shorts to the ground. I was already half erect watching the three friends of my sister had gotten me worked up. I smeared the mixture on my shaft and worked it in slowly into the soft flesh of my rod.

My cock isn’t especially long. About seven inches when fully erect. It is, however, thick. Like properly thick. My girth is my cock’s best feature. When fully erect, I have a veinous shaft and a circumcised head that is a full handful on its own.

The mixture started taking effect almost immediately.

I hadn’t tried this version before. Prior, I’d had crazy results that completely and utterly turned me on. The surprise reaction I had gotten was an unexplained and pronounced sensation of physical and mental sexual arousal. My cock would swell to a painful erection, throbbing at the end of its limits. The addition of the ferric citrate should slow the rate of the reaction completing itself and draw out the timeframe of the effect.

I felt an instant warmth and alertness. My head began to buzz.

My groin joined next, growing warm, with the same sensation I’d briefly had before—that of being connected to a nine-volt battery. What felt like a powerplant had started. My cock grew without me touching it. The feeling of bliss and pleasure in my groin joined the pain of my cock straining against its limits. My head spun and my balls ached.

My head rocked back as I grasped my thick shaft. Normally the feeling would have started to subside now, but this time, it was still getting stronger.

My thoughts turned to Kate, Lily, and Rebecca. I stroked my shaft slowly up and down.

"Luke, honey!” My mother's voice echoed through the closed door to my bedroom.

I swiftly pulled up my shorts over my throbbing member.

“Yes, Mom?"

“I’ve just gotten off the phone with Claire next door. I’ve booked her in to take a look at your shoulder. You need to go now. She’s seeing you during her lunch break.”

“Oh fuck!” I thought to myself.

“It’s ok, Mom, you don’t need to do that for me.”

"Honey," my mother continued, “she’s made room for you, so I think you should go.”

My head continued to spin as I threw on my baggiest pair of shorts I had and got my largest T-shirt out and put it on. My cock simply wasn’t going down.

“She’s said she’ll make three appointments for you before you leave. She’s so lovely!”

“Yeah, I know that much.” I thought to myself. My dick was twitching at the touch of the fleecy short’s material, which was doing a terrible job of hiding my predicament.

I pulled my shirt down and laced on some shoes before making my way out of my room and then directly to the front door. Once outside, I tried to adjust myself, but the sensations only grew. Added to the inconvenience, I continued to sweat after my run.

I made the walk to the Sullivan residence at a slow pace, willing my shaft to return to its flaccid self, but this was to no avail.

At the fenceline, a sign read “Sullivan Physical Therapy” and “Patient Entry” with an arrow pointing to a large side door that must have served as Claire’s consult space.

I took a deep breath, adjusted my shorts and shirt once more, and walked in.

A receptionist sitting behind a counter facing the door greeted me with a smile.

“You must be Luke?”

“Yes, ma'am," I replied.

“Claire will be with you in a second. Take a seat." She indicated towards a bank of four seats lined up along a wall, facing a large TV set on the opposite wall.

A few moments later, Claire emerged from one of the consult rooms.

“Hi there, Luke! How are you?” I was stunned for a moment. Her smile was as I remembered....
