Sinning With My Stepbrother: Forbidden Lust in the House of God

The words on the page burned hotter than they should have.

I pressed my thighs together under the thin white sheet and forced myself to keep reading even though my pulse was already racing.

The man in the book had the girl pinned against a wall that was supposed to be sacred. He spoke to her in a low voice while he moved inside her, his voice a low, rough groan filling her ears, telling her she belonged to him, that God could watch if He wanted.

My fingers dug into the mattress. Heat pooled low in my stomach, sharp and shameful. I told myself I would stop after this page. One more page. Just one. Now my body was throbbing and my mind was filthy.

“Fuck…” I gasped. I was close. So close. My legs started shaking and—

“Abigail Quinn Thompson!”

My mother’s voice sliced through the air like a whip. My full name? Too dramatic.

I slammed the book shut so hard it made a loud 'thwack'. The sudden silence in my room felt loud. Between my legs I was soaked, the thin cotton of my underwear clinging to me in a way that made the guilt worse.

I shoved the book, 'Forbidden Desires' under my Bible study notebook like I always did, and sat up straight, heart slamming against my ribs.

Oh God.

“Abby! You hear me, girl?” Mum called again from down the hallway. “It’s almost time for evening fellowship. Get dressed. Ten minutes.”

“Okay, Mum!” I called back, my voice shaky.

I swung my legs out of bed and stood. The room still felt too warm. I changed into the modest white sundress she liked, brushed my long brown hair into a neat ponytail, and tried not to look at my own flushed face in the mirror.

I whispered the same quick prayer under my breath I always whispered after I read that book.

‘Lord, forgive me. I know it’s wrong.’ The words felt hollower every time I said them.

Downstairs, Mum was already waiting by the front door, keys in hand. She looked me over once, the way she always did, checking that the hem sat properly and that nothing about me would draw the wrong kind of attention.

“Little birds told me tonight’s fellowship has something special in store,” she said as we walked to the car. Her voice was light, but her fingers tapped the steering wheel harder than usual once we were inside.

I buckled my seatbelt. “What do you mean?”

She gave a small shrug that didn’t match the tightness around her eyes. “I don’t know exactly. Just… be ready. God might be moving tonight,” then she paused, “after tonight, things are going to be different.”

I didn't understand what she meant by that, but I didn't sweat it either.

The drive was quiet. I kept my hands folded in my lap and stared out the window, trying to force the heat in my body to die down. Every small bump in the road reminded me of what I had been reading. I hated that my body still wanted it.

When we arrived, the chapel was already filling up. I loved this place. I hated how much I loved it while carrying thoughts that would get me stood in front of the entire congregation if anyone ever knew.

And then I saw him.

Elijah Whitaker stood near the front with his father. Tall. Broad shoulders under a crisp white shirt. His dark hair was neatly styled, but a few strands fell across his forehead. When he turned his head slightly, our eyes met for half a second.

My stomach flipped hard.

He was… God, he was beautiful in a way that felt dangerous. Thirty-eight years old and he carried it like power. Just confident and calm. Like the whole room bent toward him without trying. He smiled at something his father said, and I felt it low in my belly.

I quickly looked away, cheeks burning again.

We took our usual seats in the third row. Mum hummed under her breath beside me, but the sound felt forced. I noticed the way her eyes kept drifting toward the side doors, as if she expected someone to walk through them who did not belong.

The service opened with the usual songs and prayers. Then Pastor Matt’s face grew serious.

“Tonight,” he said, voice carrying to the back wall, “we must address sin in our midst.”

My heart dropped.

Two deacons brought forward a quiet lanky boy named Timothy. He looked terrified. His mother was already crying in the back row. Pastor Matt announced that Timothy had been caught kissing a young sister behind the fellowship hall — not once, but multiple times. He had confessed. Repentance, however, had to be public.

The shaming began.

They made him stand in front of everyone while verses about lust and disobedience were read aloud. People murmured. Some nodded. Older women whispered “Lord have mercy.” Timothy’s shoulders shook as he cried silently.

I sat frozen.

I had just been reading about a man fucking a girl against a wall. I was still wet from it. And here was Timothy being destroyed for KISSING!

‘What then would they do to me if…?’

The thought made me feel sick.

Eli stood beside his father the entire time. His face stayed calm and respectful, the perfect expression of a pastor’s son who had never once stepped outside the lines. But when his eyes flicked toward me for a brief moment, something darker and unreadable passed through them.

Or maybe I was only imagining it.

After the final prayer, people began to mingle. So did Mum. I slipped away toward the small storage room behind the main hall. I needed air. I needed a moment where no one was looking at me.

I closed the door and leaned against the wall with my eyes shut.

The door opened again almost immediately.

I jolted.

Eli stepped inside and closed it quietly behind him. The small room suddenly felt much smaller.

He looked at me differently then. Not like the pastor’s perfect son looking at a girl from the congregation, but like a man who had finally stopped pretending he didn’t want her.

“You okay?” he asked. His voice was low, calm, deeper up close. “You left pretty fast.”

“I’m fine,” I whispered, hugging my arms around myself. “Just needed a moment.”

He didn’t move closer, but he didn’t leave either. The silence stretched. I could smell his cologne — clean, warm, expensive in a way that reminded me he was not one of the youth group boys who still smelled like cheap soap.

“You looked upset during the disciplining,” he said.

I swallowed. “It was… hard to watch.”

He nodded once. Then he stepped forward and took my hand. His palm was warm and rougher than I expected. He ran his thumb slowly across my knuckles, deliberate, unhurried.

My breath caught.

“You’re shaking,” he murmured.

“I… shouldn’t be here alone with you,” I stuttered, but didn’t pull my hand away.

His eyes dropped to my mouth for a fraction of a second before returning to mine. He leaned in just enough that I felt the heat of his breath against my cheek.

“Abby.”

The way he said my name made the heat return, sharper this time. His face brushed against mine, which was barely a touch of his cheek to my temple. My eyes fluttered shut. My heart was pounding so hard I was certain he could hear it.

Then the door handle rattled.

We both froze.
