Discovering My Ass

Everyone is 18.

Chapter 1: Investigation, and Sharing

During my jerking off in the shower phase, I got really into the different types of lube available to me. I had various shampoos and conditioners to choose from, and would mix and match to whatever my cock needed on a given day. I would either use the jet setting on the shower head to blast my dick to ejaculation, or else I’d rub my shaft roughly between my lubricated palms. I distinctly remember the first time I rubbed lower. I was basically jerking off my shaft and my balls at the same time. It felt amazing as I rubbed my balls like they were a pussy. I even pulled on them, the tension adding to my pleasure.

I was yanking my balls to hell one day while stroking off, just approaching the climax when I discovered that there was sort of a second happy spot, as I thought of it. When I rubbed down my taint and pressed firmly, I was even more excited. I ventured further south until my middle finger grazed my hole, and the realization hit me. Something was inside there. The white conditioner was coating my entire crotch and taint by this point, and I slipped my middle finger deep inside, feeling my hole naturally clench down. I continued to stroke my shaft while I wiggled my finger around, adding tension where it was needed, and for the first time, jizzed clear across the tub, splattering the wall several feet away. I had discovered something that night in the shower. But I never mentioned it to anyone. I kept the secret for myself. 

Until one day.

The steam from the showers wrapped around me like a warm blanket, the scent of soap and sweat mingling in the humid air. I stood under the water, letting it cascade over my shoulders, my mind wandering as I lathered up. My buddy, Jake, was in the stall next to me, humming some off-key tune as he rinsed off. We’d just finished a grueling workout, and my muscles ached in that satisfying way that told me I’d pushed myself hard enough.

I grabbed a bottle of shampoo, turning it over in my hands. This one’s got a nice texture, I thought, squirting a dollop into my palm. I started lathering my hair, but my mind drifted back to my shower experiments. Those late nights, alone, discovering new sensations. I couldn’t help it. The memory of that first time—when I’d slipped a finger inside myself—flashed through my mind, and I felt a familiar heat pooling low in my stomach.

“Man, I’m so sore,” Jake called out, his voice echoing off the tiled walls. “I can barely lift my arms.”

I chuckled, rinsing the shampoo from my hair. “Yeah, but it’s a good sore, right? Means you’re getting stronger.”

“I guess,” he said, and I heard the water in his stall shut off. “Hey, you got any of that lotion? My skin’s dry as hell.”

I reached for the bottle on the shelf and tossed it over the partition. “Here, catch.”

“Thanks,” he said, and I heard the sound of him slathering it on.

I turned my attention back to my own body, running my hands over my chest and down my stomach. The water was warm, and my skin felt alive under its touch. I couldn’t resist—I let my hand drift lower, wrapping my fingers around my cock. It was already half-hard, and I gave it a slow stroke, my breath hitching.

“You know,” I said, my voice casual, like I was just making conversation, “if you really want to relax, you should try something.”

“What’s that?” Jake asked, his voice muffled by the sound of the water.

“Rub your taint. Or, you know… go further.”

There was a beat of silence, and then Jake’s voice came through, incredulous. “What the fuck are you talking about?”

I hesitated, my hand stilling on my cock. Shit. Did I just say that out loud? But it was too late to take it back now. “I mean, it feels good. Just… try it sometime.”

“Dude, are you seriously telling me to stick a finger up my ass?”

I could hear the skepticism in his voice, but there was something else too—curiosity. I couldn’t help myself. “Yeah. Seriously. It’s… intense.”

“You’ve done that?”

I swallowed, my heart pounding. “Yeah.”

“No fucking way.”

I could tell he was intrigued, even if he was trying to play it cool. I decided to push a little further. “It’s not as weird as you think. Just… trust me.”

There was another pause, and then Jake’s voice came through, low and hesitant. “Show me.”

My breath caught. “What?”

“Show me how you do it.”

I froze, my hand still wrapped around my cock. Is he serious? I glanced over the partition, and there he was, standing in his stall, water running down his body, his eyes locked on mine.

“You’re not messing with me?” I asked, my voice barely above a whisper.

He shook his head. “No. I want to see what the big deal is.”

My heart was racing now, my cock fully hard in my hand. I hesitated for a moment, then stepped out of my stall, crossing the short distance to his. The air was cooler outside the stream of water, and I shivered slightly as I stepped into his stall.

Jake was watching me, his eyes dark with curiosity, and his big, hard cock pointing up to the ceiling. He didn’t say anything, just stepped back to give me room.

I reached for the lotion he’d been using, squirting a generous amount into my palm. I hesitated for a moment, then turned to face him. “You sure about this?”

He nodded, his jaw tight. “Yeah. Show me.”

I took a deep breath, then reached down, my hand slick with lotion. I started with my taint, rubbing firmly, letting the pressure build as I slowly tickled my shaft. Jake’s eyes were locked on my hand, his breath coming faster, his own hands mimicking mine on himself.

“You can feel it, right?” I asked, my voice low.

He nodded, swallowing hard. “Yeah.”

I kept going, my fingers moving lower, until the tip of my middle finger brushed against my hole. I glanced up at him, and he was watching, rapt, his eyes wide.

“Just… relax,” I murmured, and then I pressed inside.

The feeling was electric, my hole clenching around my finger as I worked it in deeper. I could feel every nerve in my body lighting up, my cock throbbing in time with the movement of my hand.

“Fuck,” I breathed, my eyes fluttering shut.

I opened them again to see Jake staring at me, his hand moving over his own cock. He was stroking himself slowly, his eyes never leaving mine.

“Do it,” he said, his voice rough.

I nodded, my fingers moving faster now, working in and out of myself. The sensations were overwhelming, my body trembling with pleasure.

“Holy shit,” Jake gasped, his hand moving faster on his cock.

We were both breathing hard, the sound of the water and our movements filling the air. I could feel the pressure building inside me, my orgasm just out of reach.

And then I heard it—a chuckle.

My head snapped up, and I saw him—an older guy, maybe twenty or so, standing at the entrance of the shower. He was as naked as we were, his thick, heavy man-cock hanging between his thighs, just watching us, a smirk on his face.

Jake froze, his hand stilling on his cock. “What the—”

The guy just grinned, giving us a thumbs up.

I stared at him, my heart pounding, my finger still inside myself. He didn’t seem fazed at all, just watching us with that same amused expression. I saw his dick twitch, and got a thrill that he was watching us.

Jake turned to me, his eyes wide. “What do we—”

But before he could finish, the guy chuckled again, shaking his head. He turned and walked away, leaving us standing there, unsure of what to do next.

My finger was still inside me, Jake’s hand still on his cock, and the water was still running, steam rising around us.

“So…” Jake said, his voice trembling slightly. “What now?”

Jake hesitated, his eyes darting between me and the now-empty doorway. His left hand was still rubbing his taint, not fully penetrating his hole but rubbing around the edge. I could see he wasn't sure what to do. It wasn't coming naturally to him like it did to me. “I… I don’t think I’m doing it right,” he admitted, his voice shaky. “Can you… show me? Like, actually?”

My heart skipped a beat. “You want me to… finger you?”

He nodded, his cheeks flushed but his gaze steady. “Yeah. I need to know what it feels like.”

I swallowed hard, my cock throbbing at the thought. “Okay,” I said, my voice barely audible. “Turn around.”

Jake turned, bracing his hands against the tiled wall, his ass slightly raised. I grabbed the bottle of lotion again, squirting some onto my fingers. My hands trembled as I reached out, my slick fingertips brushing against his taint. He gasped softly, his body tensing.

“Relax,” I murmured, rubbing gently. I could feel his muscles slowly loosen under my touch. I moved lower, my breath hitching as my middle finger circled his hole. “Ready?”

He nodded, his head dropping forward. “Do it.”

I pressed inward, my finger sliding into him with surprising ease. Jake let out a low groan, his ass clenching around me as he started ripping at his dick with fury. “Fuck,” he breathed, his voice rough. “That’s… that’s weird. But… good.”

I started moving my finger, in and out, slowly at first, then faster. Jake’s breathing grew heavier, his hips rocking back against my hand. “Wait,” he gasped. “There’s… there’s something…”

I curled my finger slightly, searching, and then—he cried out, his whole body jerking. “Holy shit!” his whisper was like a scream, his cock twitching in his hand.

“Yeah,” he said in a strained voice, "that's it."

I kept pressing against that spot, my own cock aching with need. Jake was jerking himself furiously now, his moans echoing off the walls. “Fuck, I’m gonna—I’m gonna—”

He came hard, his cum shooting out in thick ropes, splattering across his abs, his dick, and his balls. The sight of it pushed me over the edge, and I groaned as I came too, my own release landing right on his stomach, mixing with his.

We both stood there, panting, the water still running over us. Jake turned to look at me, his chest heaving. “That was… fucking insane, dude.”

I nodded, pulling my finger out slowly. “Yeah. It’s… intense.”

He glanced down at the mess on his stomach, then back at me, a grin spreading across his face. “Guess you were right.”

I chuckled, my heart still racing. “Told you.”
