Guilt sex

We were still on the couch when Mom suddenly turned to me during a quiet moment in the movie.

“So honey, when does the break end? I know your college is closed right now, but have they announced when classes are resuming?”

Her innocent question made my stomach twist. Derek’s fingers were still deep inside me under the blanket, slowly stroking my walls while his thumb teased my clit.

I tried to keep my voice normal. 

“They said two more weeks for now. Maybe longer if the renovations aren’t finished.”

Mom nodded. 

“That’s good. At least you get more time at home with us. We should make the most of it while you’re here every day.”

Derek’s fingers curled against my g-spot at the same time. 

“Exactly,” he said smoothly, voice perfectly 

casual.

“More time for family bonding.”

I came hard on his hand, biting my lip bloody to stay silent while smiling weakly at my mother. The pleasure mixed with heavy guilt as I clenched around my stepdad’s fingers.

Later that night, I was lying in bed, still sore and sticky, scrolling through my phone while texting my friend. My pussy throbbed with every small movement, and I could still feel Derek’s cum slowly leaking out of me onto my sheets. My neck and breasts were covered in faint marks, and my throat felt raw from how deep he had fucked my mouth.

The door suddenly opened.

Mom walked in with a glass of juice in her hand, smiling softly as she approached.

“Thought I’d get you something before bed,” she said, placing the cold glass on the bedside table. She sat on the edge of my bed, looking at me with warm, loving eyes.

“Thank you, Mom,” I smiled, trying my best to look normal even though my legs were still trembling slightly.

“I should be the one thanking you, honey.” She reached out and gently brushed a strand of hair from my face. “Thank you for accepting Derek. I know it was hard for you at first, but believe me, I’m going to make this work. He really cares about us. I can already see the bond forming between you two.”

My stomach twisted violently. Guilt crashed over me like a wave. Just a few hours ago, her husband had me bent over in his bed, calling him Daddy while he pounded me senseless and filled me with his cum. And now here she was, sitting on my bed, looking so grateful and hopeful.

I forced another smile, even as I felt a fresh trickle of Derek’s cum drip out of my sore pussy.

“Yeah… it’s fine, Mom,” I replied, my voice a little hoarse. “I’m trying.”

Mom’s face softened even more. She leaned in and kissed my forehead tenderly, just like she used to when I was little.

“That’s all I ask, sweetheart. I just want us to be a happy family. You, me, and Derek. I love you so much.”

“I love you too, Mom,” I whispered. The words tasted bitter on my tongue.

She stayed for a moment longer, rubbing my arm affectionately before finally standing up.

“Get some rest, okay? Don’t stay up too late on that phone.”

She gave me one last smile, then turned and walked toward the door. Just before she stepped out, she paused and looked back at me.

“Goodnight, honey.”

“Goodnight, Mom.”

The door clicked shut behind her.

I let out a long, shaky breath and dropped my phone onto the bed. My heart was racing, and the guilt sat heavy in my chest. But even worse than the guilt was the way my pussy clenched again at the memory of Derek’s thick cock stretching me open… and the dark realization that I was already wondering when he would sneak into my room again.

****

The next morning, I woke up sore and conflicted. My thighs were sticky, my neck covered in fresh hickeys. I couldn’t keep doing this. Not with Mom in the house. Not when I was resuming soon.

I waited until I heard Mom leave for her morning jog. She always did that every morning. Once the front door closed, I walked down the hall to their bedroom.

Derek was still in bed, shirtless, scrolling on his phone. He looked up when I entered, a slow, predatory smile spreading across his face.

“We need to talk,” I said firmly, closing the door behind me.

“This has to stop. Yesterday was the last time and I mean it, Derek. Stay away from me.”

He set his phone down and sat up, muscles flexing. 

“Is that what you really want, princess?”

“Yes,” I lied, my voice shaking. 

“It’s too dangerous. She’s going to find out.”

Derek stood up slowly and walked toward me. I backed up until I hit the wall. He caged me in with his arms, towering over me.

“You say that,” he murmured, sliding one hand under my oversized t-shirt and cupping my bare pussy, 

“but you’re soaked again.”

“Derek—” My protest died as he pushed two thick fingers inside me.

“Tell me to stop then,” he challenged, pumping them slowly. 

“Tell Daddy to stay away while you’re dripping down my hand in the bed I share with your mother.”

I moaned, hips rocking against his fingers despite myself. The guilt only made me wetter. He kissed me hard, swallowing my sounds, then spun me around and bent me over the edge of their bed.

In one smooth motion, he shoved his cock inside me, stretching my sore pussy wide open again. I cried out, gripping the sheets.

“Fuck…. we can’t—”

But he was already pounding into me, harder than ever. The bed creaked under us. He gripped my hips and fucked me with deep, possessive strokes, his balls slapping against me.

“This is my pussy,” he growled. 

“You don’t get to tell me to stay away. Not when you come crawling in here looking for my cock.”

I came embarrassingly fast, biting the sheets to stay quiet as my orgasm ripped through me. Derek didn’t slow down. He fucked me through it, then pulled out, flipped me onto my back on their marital bed, and slid back inside me.

“Look at me while I fuck you in your mother’s bed,” he ordered.

I obeyed, staring into his dark eyes as he took me with long, powerful thrusts. Tears of overwhelming pleasure and shame slipped down my cheeks.

He leaned down, biting my neck as he got close.

“Gonna cum inside you again, princess. Right here where your mom sleeps.”

I wrapped my legs around him, pulling him deeper as another orgasm hit me. Derek groaned and buried himself to the hilt, flooding my pussy with hot, thick ropes of cum.

We stayed locked together, breathing hard.

Then we heard the front door open downstairs.

Mom was back from her jog.

Derek smirked, still buried deep inside me, his cum already starting to leak out around his cock.

“Better get up, princess,” he whispered darkly. 

“Or Mommy’s going to find you stuffed full of her husband’s cock in her own bed.”

I scrambled off the bed in panic, Derek’s cum running down my thighs as I tried to fix my clothes. My legs were shaking so badly I could barely stand.

Derek simply lay back against the pillows, cock still half-hard and glistening with our combined juices, watching me with dark amusement.

“Tonight,” he said quietly as Mom’s footsteps started up the stairs. 

“Expect me tonight and this time… I’m taking your ass.”
