Becca followed the creek in the woods once again. It was just yesterday that she'd brought me here the first time, but so much had happened that it felt so long ago. I had infested two people already, one being my own wife, and if Becca hadn't already been the bug queen, I would have infested her too. Nothing would ever be the same for us again, and here I was, willingly walking back to the source of this undoing of my family. It should have bothered me, I knew it should, but all I wanted was to be packed with bugs, to let them use my body to proliferate.
The trek to the cave felt like a death march. My balls ached and itched. My cock yearned to be loaded. I hadn't been empty this long since Becca had first impregnated me, and her ass and hips swaying in front of me as she walked didn't help things. My dick strained against my sweatpants, desperate to find relief, and if we weren't on our way to insect heaven I'm certain that I would've lost the willpower to let Becca keep walking. I resolved to save myself for the cave, and mercifully, we arrived after just a few minutes more.
Becca and I stood a moment at the mouth of the cave. A slow, cool current of air washed over us from the dark opening, mixed with the echoes of the creek trickling down onto ancient stone. Now that we were here, I found that I was actually nervous. There was a pit forming in my stomach as I realized the uncertainty that lay ahead. I had no idea what I was actually getting into.
Becca lifted her shirt up over her head and dropped it onto the forest floor, exposing her bare breasts to the chilly breath of the cave. She unbuttoned and unzipped her pants, scooted them down to her ankles, and removed them. She shivered as she stood, her naked body covered in goosebumps, and turned to look at me expectantly.
I quickly followed her lead, tearing my shirt off and dropping my sweatpants. My stiff cock bounced up proudly in the icy breeze, leaking precum, begging to be invaded.
"Well look at you!" Becca laughed, "I guess that means you're ready, then?"
My heart beat in my chest and the head of my dick. I simply nodded in response, both too horny and too nervous to form words.
"Don't worry, we won't go too deep, Daddy," Becca grabbed my hand and smiled softly. I nodded again, and she moved toward the cave's entrance, tugging me along behind her. She took the first precarious steps down into the hole, using me for balance, before pulling me in after her. It was darker and colder inside the first passage than yesterday. The low sun cast a deep orange shaft across the far wall, leaving everything else hidden in shadow. The air was damp, heavy with moisture that clung to our bare skin.
As we moved further in, the splashing at the back of the cave grew louder, where the creek cut down into the next passage. My heart rate skyrocketed as we approached the drop, still a torturous mix of anxiety and anticipation. Becca definitely would have heard the thumping in my chest if it weren't for the water. I was here, this time for real.
Becca climbed down through the opening, soaking her skin in the cold water as she went. She disappeared into the total darkness, swallowed by the cave. Not enthusiastic about being separated from my guide, I quickly followed after her. I sat opposite of the creek on the lip of the hole and lowered my legs down first. I soon realized my dick was so big that the only option was to let it fold up against me as I descended. With a sigh, I stood up onto my arms and let my hips down next, drowning my cock in the icy waterfall. I dropped as fast as I could, and found myself surrounded by oppressive blackness. The hole I'd come through was all that I could see, a faint light in the roof of the passage.
"Becca?" I called.
Nothing.
"Becca?!" I shouted. My voice echoed deep into the gloom, but no reply came. Fuck. Where the fuck was she? Becca was definitely not above a prank, even in a scenario like this. Especially in a scenario like this, actually. Either that, or...she was already busy. Could she be with a bug so soon? My cock twitched at that thought, and I pressed on into the dark.
I squinted to see my feet as I walked, but I couldn't even see my hand in front of my face. I had to shuffle along, carefully feeling for drops or sharp edges. As my eyes strained, they became irritated. They welled with tears, like I was allergic to the dark, and despite blinking and rubbing them, the feeling only got worse. I squeezed my eyes shut for several seconds, trying to clear whatever was causing this pain, and underneath my eyelids, I felt myself blink... sideways.
I shook my head and opened my eyes wide in shock. My second lids blinked a few times more, and I saw a sort of pattern, like TV static, that slowly coalesced into shapes and shadows. The walls of the cave revealed themselves to me. I could see the creek running down the passage, and the offshoots that Becca had me explore the first time. It wasn't normal sight, sort of a black and white, fuzzy picture, and only of my immediate surroundings. Darkness still permeated the periphery of my view, but it was better than nothing. My skin was bright, and I was steaming, especially off my cock, while the creek was pitch black. I could see my footprints trailing behind me, glowing on the stone floor. I had developed some form of rudimentary thermal vision.
I quickly discovered a second set of footprints on the other side of the creek that split the passage in half. They had to be Becca's.
I followed her footprints, each one glowing faintly, a small flicker of warmth in the oppressive dark of the cave. My own feet stamped glowing imprints on the cold stone with every step. This new thermal sense let me see, but it made the darkness feel colder, more suffocating, like the air itself was holding its breath.
Her trail was still warm, and I had dropped through the hole so soon after her. She had to be close, right? That small hope faded quickly when I noticed something. Deeper into the cave, the trail... stopped.
I froze, my heart pounding painfully in my chest. I stared at the last glowing footprint as it slowly faded, swallowed up by the cold. She couldn't have just vanished! She'd been here, just moments ago, but her footsteps didn't continue.
Panic clawed at me. I wasn't expecting to face this cave alone, and my fear was overpowering my lust. I didn't want to be here without Becca. I forced myself to breathe, to stay calm.
I stepped forward, my feet heavy, and scanned the floor, desperate for any sign of her. But there was nothing. No new footprints. Only the dim glow of my own trail, as cold as the rest of the cave.
