Locked Down With Stepdaddy

"Unexpected"

I stayed frozen in the stretch for one more second, the hard press of him still burning against me through the thin leggings. Then I straightened up too fast, nearly losing my balance on the mat.

“What the fuck,” I kept muttering under my breath, somehow managing to keep my face blank as I rolled the mat up with shaky hands.

I didn’t even look at him, more like I couldn’t. If I looked at him right now he would see everything written across my face.

I walked toward the stairs at a normal pace even though every muscle in my body wanted to sprint. My heart was slamming so hard. The contact had only lasted a couple of seconds but it was enough. More than enough.

The second I reached the top of the stairs and turned into the hallway I ran. I shoved my bedroom door open, stepped inside, and shut it harder than I meant to. My hair had fallen all over my face. I pushed it back with both hands and leaned against the door, breathing like I had just finished running for a world cup.

“Why did he have to come up behind me? Why?”

I reached back and touched my ass through the leggings. I could still feel exactly where the thick line of his cock had pressed into me. That slight contact had done too much. It had woken up every secret I kept locked down tight.

“I hope he doesn’t notice,” I whispered, almost like a prayer. “Please don’t let him notice.”

Would my prayers even get an answer tonight?

I shook my head and walked over to the bed, dropping onto the edge of it.

The fact that my mum married Mark only a few months after Dad died had never been the real problem.

The real problem was that I kept finding him attractive. I kept getting drawn to him in ways that made my stomach twist with guilt. That was why I had maintained such a clear distance all this time. I hid behind the excuse of being angry about the marriage because it was safer than admitting the truth.

And the truth was ugly.

"Why the hell would she marry a man who looked like that? A man with a body like his and a cock that thick? I had seen enough to know."

“Oh no,” I muttered, clapping a hand over my mouth and glancing around the room like some ghost might have heard the thought. My cheeks turning pink.

Three days ago I had gone into his room while he was downstairs and set my phone in the usual spot, angled toward the bathroom entrance.

I had started this a few months back. The first time had been an accident. I walked into his room at the wrong moment and saw him standing under the shower spray with his bathroom door opened, one hand braced on the tile, the other wrapped around himself, stroking slow and hard.

After that I started planning it. Every time I came home I found a way to leave my phone recording. I would wait until he left the house or went for a run, then slip in, grab the phone, and lock myself in my room to watch later.

I reached for my phone with unsteady fingers, unlocked it, and opened the gallery.

The newest video was still there, waiting. I tapped it.

The screen lit up with the familiar angle of his bathroom. For a few seconds there was only the empty tile and the sound of the shower running. Then he stepped into the frame, completely naked, water running down the hard lines of his chest and stomach.

He didn’t know. He had no idea I had been collecting these moments like secrets. He had no idea that the girl who barely spoke to him downstairs had watched him come undone more times than she could count.

I swallowed hard and kept watching, the earlier press of him against me still vivid on my skin, mixing with the one on the screen until my breathing turned shallow again.

My free hand slid down between my legs and pressed against my down through the leggings.

I rubbed slowly at first, just enough pressure to make my hips shift on the bed. The video was still playing. Mark’s hand was wrapped around his little one, stroking in that steady rhythm I already knew by heart.

I dropped the phone on the bed beside me and used my other hand to push the yoga top up. My fingers found my chest, squeezing, thumb brushing over the head until it hardened. A soft sound slipped out of me.

“Hmmn…”

I kept rubbing, a little faster now. The fabric of the leggings was getting in the way. I hooked my thumbs into the waistband and dragged them down over my hips, then my thighs, until they were bunched around my knees. I pulled the yoga top the rest of the way off and tossed it aside.

Now I was practically without anything on my bed, legs open, one hand back between my thighs.

My fingers slid through the wetness that had already gathered. I was soaked. I circled my down slowly, then slipped two fingers lower and pushed them inside.

“Fuck…”

My eyes stayed on the phone screen. In the video he was leaning one hand against the shower wall, head tilted back, the thick length of him sliding through his fist.

I imagined it was that same little one pressing against me from behind again like it had downstairs. Only this time there were no clothes between us. This time he would push forward and sink into me from behind while I was still bent over that stupid yoga mat.

I moaned louder and curled my fingers, working them deeper. My other hand stayed on my chest, pinching the head harder than I usually did.

“God… Mark…”

The name came out before I could stop it. I bit my lip but didn’t slow down. In my head he was right here. He had followed me upstairs. He had seen the look on my face after that accidental press of his cock and decided he didn’t care that I was his stepdaughter. He would shove me onto this bed, pull my legs open, and bury himself inside me in one long thrust.

I added a third finger and did myself harder, hips lifting off the mattress to meet every stroke. My breathing turned ragged.

“Yes… just like that… me…”

I was so close already. The combination of the video and the memory of him against me from behind and the filthy pictures in my head was too much. My fingers moved faster, chasing the edge, my other free hand left my chest and gripped the sheet.

“I’m gonna come… I’m—”

A knock on the door.

“Benita, are you fine?”

Mark’s voice came through, low and close, and the sound of it jolted me so hard I froze with my fingers still buried inside myself.
