"I wonder if they know it's a dead end?" I thought, watching the set of rear lights disappear around the corner ahead of me.
"Maybe they're looking for some peace and quiet too," came the further thought, as I heard the rattle of car tyres over the narrow wooden bridge.
I mentally shrugged; if they were just lost, they'd come back past me soon, perhaps stopping to ask for directions. And if not, well the seating area by the side of the Centre was big enough that we could sit at opposite ends and still be in our own little bubbles of quiet.
I kept walking, my thoughts rolling around my head, and came to the bend that led to the Centre. Turning the corner I could see the bridge, and the sign beside it, with the washed out light illuminating the words "Altrinton Nature Reserve and Research Centre". Underneath were the opening times, and contact details, but I already knew the Centre was closed, so I paid them no mind.
I took out my phone and took a photo of the sign, posting it to the WhatsApp chat I shared with my wife, that way she'd know where I was. Even though I'd left the house in a temper I still didn't want her worrying about me too much.
It was as much my fault as hers, probably even more mine, if I was honest about it. I'd known how much pressure she was under with work, and for whatever reason I didn't make allowances for that. Trivial things blew up, and we had a peeling-paint-off-the-walls argument which ended up with me getting my keys, announcing that I was going to get some fresh air and calm down, and leaving the house.
That was actually the right thing to do, since based on the few rows we've had in the past I needed to give us both some space to get our thoughts clear, calm down, and ideally be ready to discuss the issues rationally.
I'd been unsure where I was going, but as I reached the end of our street I'd remembered that there was some seating near the Centre, looking out over one of the lakes, and decided I was going to walk the mile and a half there (and back) to burn off some energy and anger, and then sit in quiet and work out exactly how each of us had fucked up and what I was going to do to fix my side of things.
Strolling across the bridge, I looked to my right, in the direction of the Centre. I could see the trees on the side of the river, then beyond them some dim street light type lights which I thought must be in the carpark, but after that it was too dark to see anything. I realised that having artificial lights around a nature reserve might be a problem, and perhaps the carpark lights being dim was some sort of compromise to meet legal requirements.
Carrying on with my walk in the cool spring air, I reached the next bend, which lead to the carpark. I still hadn't been passed by the car leaving, so I assumed the driver was also there for some peace. How wrong I was...
As I rounded the bend and saw the carpark proper I could see.. actually, for you to understand this, I need to explain the layout of the carpark. It's basically a rectangle, with the entrance at one narrow end, and the actual Centre and office building at the other. There's a line of parking spaces on the wide side to the left, then an aisle, then two more rows of spaces, then another aisle, then a final set of spaces next to the trees on the riverbank.
So, as I was saying, I saw that I was right about the lights being in the carpark; there were six of them, all carefully configured so they didn't send any light upward, only downward and slightly outward. Two were throwing light onto the spaces on the right, two between the centre rows, and then two more illuminating the other row. Although, as it turned out, the last set were illuminating more than just the spaces...
The entrance to the carpark from the road is about two cars in length, and there's wild shrubs growing a little way back from the edges, so my view of the right-hand side of the carpark was obscured as I walked down the grass strip. I could see three, maybe four, cars in the centre parking area, and as I got about halfway down the road I saw someone walk from the right, and get into their car. They sat for a moment, then started the engine, turned on their lights, and drove out. They didn't use dipped beams and I was a bit blinded by their lights, so I stopped to wait for my night vision to return.
They rattled across the bridge on their way out, and as the sound faded I realised I could hear something odd; a sound I'd not heard before when I'd visited the Centre in the day time. It was a rhythmic sound, an odd slapping sound, like when a swan is landing on water, but slower; but overlaid with it was some sort of gentle almost breathy sound, as if the wind was moving through the trees and making them moan.
My eyes recovered and I started walking, but after a couple of steps I stopped again. That sound. It was coming from my right, as if it was being generated in the carpark. I still couldn't work out what it was; it reminded me of... no... I must be wrong... oh my... I realised that what I was hearing sounded a lot like flesh slapping together, someone getting spanked, or a stomach slapping against buttocks. I took a couple of steps forward, then another couple, and then a couple more. Each time the sound got a little louder, as if the shrubs and bushes were muffling it and as there were less of them, so the effect was reduced.
I came to a dip in the bushes and was able to see one of the lights, shining down into the carpark, illuminating a scene I'd only ever read about. I couldn't see clearly, there were still some long stems from the shrubs in my way, and there wasn't that much light, but I was sure of what I saw.
A car, more specifically a saloon (or sedan if you're in the US) type, parked directly under the light. Bent over the boot, a woman, at least I assumed a woman, long legs, appeared to be naked from the waist down apart from stockings, and standing behind her, someone moving back and forth in time to the sounds I could hear. I could also see at least two or three other people standing around.
My body reacted; my cock became hard, my heart rate went up, my brain went "wibble". I had a choice to make:
