Backdoor Tune-Up

Connor glanced back at me, curiosity flickering in his eyes, but he obeyed. As he spun slowly, I caught sight of his dick—hard, aching for attention, the head flushed and glistening. My gaze trailed down his slim, toned frame to the curve of his ass—round and smooth, with a pinkness at the center that made my breath catch.

I reached out, my hand resting lightly on his hip before trailing lower. My fingers brushed against his hole, the warmth of his skin almost overwhelming. I circled it once, feeling the way his body tensed under my touch, but he didn’t pull away.

“You’re… tight,” I murmured, my voice low and rough.

Connor let out a quiet laugh, glancing over his shoulder. “Oh, shit, Ryder! That feels good…”

I didn’t answer. Instead, I pressed lightly, testing the resistance. He let out a soft sound—a quiet sigh that sent a jolt straight through me. My imagination ran wild with the thought of shoving inside him, stretching him, feeling his tightness around me. I glanced down, catching sight of his hand moving over his dick, jerking himself steadily as I continued probing his hole.

I leaned in closer, my hand sliding up his back, feeling the way his muscles shifted under my touch as the water cascaded over us.

He turned fully toward the wall, his pace quickening as he stroked himself harder, his body moving with a rhythm that made the heat between us almost unbearable. The sight of him like this—completely unguarded, completely into it—made my chest tighten.

I let my hand trail lower again, circling his entrance with more intent. Connor moaned softly, his hips tilting back slightly, inviting me closer. My finger pressed in gently, the tightness giving way just enough for me to slide inside. He gasped, his movements faltering for a moment before he picked up speed again, stroking himself faster.

“Fuck, Ryder,” he murmured, his voice shaky. “That feels… so… good…”

I pushed my finger in deeper, curling slightly, feeling his heat and the way his body clenched around me. Each squeeze sent a fresh wave of heat through me, my semi growing harder as I imagined what it would feel like if it were my dick instead. The thought hit me hard, and for a moment, I almost asked him if I could—but reality snapped back just as quickly. My mom would be home soon. This wasn’t the time—not yet.

I leaned in as close as I could, my breath brushing his ear. “Cum for me, Conn. Do it.”

Connor’s body tensed at my words, his breath hitching. “Ryder—I’m—” he gasped, his voice breaking. His body shook as he came, his cum jettisoning against the shower wall in thick, hot spurts. I felt his ass clench hard around my finger, the sensation so tight and intense it made my own pulse race, almost wishing it was my dick inside him instead. His hand slowed as he rode out the release, I almost had to support him so he didn’t fall down.

We stood like that for a while, me supporting his whole body as his breathing began to steady. Once his breaths became less ragged, I slowly pulled my hand out, feeling his muscles shift as he started holding himself up again.

“Wow, you’re impressing me here, Ryder. I thought I was supposed to be the coach,” he chuckled, glancing back at me with a playful grin.

“I may know a thing or two myself,” I said with a wink. He had no idea where I’d picked it up—from his own dad….

After Connor left, I went straight to cleaning up. First the couch downstairs, wiping away the traces of what we’d done, and then the shower wall, rinsing away the streaks of cum before they could leave any evidence. The water ran hot over my hands as I scrubbed, focused on erasing every last sign of what had happened. I was so caught up that I didn’t hear the bathroom door creak open behind me.

“Wow, I’m impressed!” my mom’s voice cut through the sound of the water, making me jump. “Cleaning the shower without me nagging for a week? Who are you, and what have you done with my son?” she teased, leaning against the doorframe with a chuckle.

I spun around, heart racing as I tried to play it cool. “Uh… just figured it needed it,” I mumbled, turning back to rinse the sponge.

She smiled, clearly amused. “Well, I’m not going to complain. Honestly, I’ve noticed some real improvements since you started at the body shop. You’ve been more responsible… with the exception of that incident with that stoner friend of yours.”

Her words hit a nerve, but I kept my focus on the tiles, scrubbing one last time for good measure. “He’s not my friend anymore,” I said firmly, glancing over my shoulder.

“Good,” she said with a nod, her voice lighter now. “You don’t need that kind of influence.”

I gave her a quick smile, hoping she wouldn’t linger. “Yeah, I know.”

Satisfied, she stepped back, muttering something about dinner. As soon as the door clicked shut, I let out a breath I hadn’t realized I’d been holding and tossed the sponge into the bucket.

Later that night, before going to sleep, I had to jerk off one last time. The spurts were surprisingly strong, especially considering it was my third cum that day. I definitely had new material for my spank bank now—both father and son firmly included.
