Chapter 10: Erosion
Incest Sex Story: Chapter 10: Erosion - Vic is fourteen when she decides she wants her father — not in the way daughters are supposed to. She gets what she wants. What she doesn't expect is everything that comes after: four years of something that starts transactional, turns intimate, and gets complicated by guilt, a best friend who doesn't know, real ambition, and the question of what she's willing to sacrifice for what she wants. Coming of age was never supposed to look like this.

Two months after the clinic.
Madison looked better. Not good exactly, but better.
At lunch she laughed at Jenna’s jokes. Ate her food. Talked about spring break plans.
Still quieter than before. Still tired-looking some days. But functional.
Jenna noticed. “You doing okay? You were really weird for a while there.”
Madison shrugged. “Just stressed. Family stuff.”
“Everything okay now?”
“Getting there.”
Jenna looked skeptical but didn’t push.
I caught Madison’s eye across the table. Brief moment.
She gave a small smile. I’m okay.
I nodded. I know.
Nobody else saw it.
At home, things were normal.
If normal meant having sex with your father three times a week.
We still used condoms. Every time.
Dad’s office. Thursday night. Door locked.
He was inside me, moving steady, and I was watching his face.
Eyes closed. Jaw tight. Hands gripping my hips.
His breathing changed—got rougher, less controlled. Close.
Then he slowed deliberately. Held himself still for a few seconds. Breathing hard through his nose.
When he started moving again, the rhythm was careful. Measured. Like he was counting in his head.
When he finally came, his whole body went rigid. Face buried in my neck. Shaking.
After, he stayed there. Didn’t move. His jaw was still clenched.
“You okay?”
“Yeah.”
But his hands were trembling slightly where they rested on my hips.
Saturday afternoon. His office again.
Same thing.
He’d get close and then stop. Hold himself completely still. Breathe. Then start again.
The third time he did it, I felt him shaking.
“What are you doing?”
“Nothing. I’m fine.”
He wasn’t fine.
When he came it was almost silent. Just his breath catching. His fingers digging into my skin.
After, he got dressed quickly. Sat at his desk. Opened his laptop.
“I should finish this report.”
Not looking at me.
I got dressed too. Left.
Monday. Late afternoon. I came home from Jenna’s.
Dad was in the kitchen. Making dinner.
Mom was upstairs. I could hear the shower running.
“Hey,” I said.
“Hey, sweetheart.”
I grabbed water from the fridge. Watched him chop vegetables.
His jaw was tight. Had been for days.
“Dad?”
“Hmm?”
“Are you mad at me?”
He stopped chopping. Looked up. “What? No. Why would I be mad at you?”
“I don’t know. You seem ... I don’t know.”
He set down the knife. “I’m not mad at you.”
“Then what?”
He went back to chopping. “Nothing. Just work stuff.”
“Is it though?”
He didn’t answer.
Mom came downstairs then. Hair wet. Already in her scrubs.
“Smells good.” She kissed Dad’s cheek. “I have to leave in twenty. Early shift.”
“Okay.”
She grabbed her bag. Started checking she had everything.
Dad kept chopping. Face neutral.
But I saw his knuckles. White where he gripped the knife.
That night after Mom left, I went to his office.
He was at his laptop. Some spreadsheet open.
I closed the door.
“Can we talk?”
He looked up. “About what?”
“About whatever’s wrong.”
“Nothing’s wrong.”
“Dad.”
He closed the laptop. Rubbed his face with both hands. Stayed like that for a moment.
“The condoms,” he said finally. Quiet. “I just—”
He stopped.
I waited.
“It’s nothing. Forget it.”
“No. Tell me.”
He looked at me for a long moment.
“It doesn’t matter what I want. We have a rule. I’m following it.”
“But you don’t want to.”
He didn’t answer. Just stared at his hands.
“How bad is it?” I asked.
“Bad enough.”
He stood. Walked to the window. Looked out at the dark backyard.
“When I’m inside you, there’s this barrier I can’t get past.” His voice was quiet. Flat. “And I know that’s the point. I know. But I still—”
He stopped.
“You still what?”
“I hate reaching for that drawer. I hate the pause. The interruption. I hate that I can feel the difference every single time.”
I walked over. Stood next to him.
“I broke your trust,” he continued. “In August. I took off the condom without asking. I came inside you. You made a rule after that. A good rule. And I don’t get to complain about it now just because it’s hard.”
“But it is hard.”
“Yeah.” He looked at me. “But you made the rule for a good reason. Because I fucked up. Because you needed to feel safe.”
“And I do,” I said. “Feel safe.”
“Good.”
“No—I mean I do now. Really.” I took a breath. “I didn’t after August. I didn’t trust you the same way. But now—”
I thought about the clinic. About him driving Madison without asking questions. About the way he’d given her his number. Told her to call if she needed anything.
“Now I do. Trust you.”
He went very still.
“Because of Madison?” he asked quietly.
“Yeah. You showed up. You helped. You didn’t—” I searched for words. “You didn’t ask for anything. You just did it because I asked.”
He was quiet for a long moment.
“So what are you saying?”
“I’m saying maybe we don’t need the rule anymore.”
His breath caught.
“Vic—”
“I’m on day four. Of my cycle.”
He stared at me.
“That’s—that’s really low risk,” I continued. “Before day ten, it’s about as safe as it gets.”
“It’s not zero.”
“No. But low.” I looked at him. “And if something did happen—if somehow—you’d help me figure it out. Whatever I decided.”
“Yeah. I would. Always.”
“So can we? Change the rule?”
He pulled me close. Held me tight. I felt him trembling slightly.
“Are you sure?”
“Are you?”
“Yes. But only if you’re sure.”
“I am.”
“Okay,” he whispered. “Okay.”
We moved to the couch.
He pulled my shirt off. Then my bra. His hands found my breasts immediately. They always did. Like gravity.
I’d gotten fuller over the past few months. He noticed every time. His thumbs circled my nipples. Made them hard.
“Perfect,” he breathed.
My jeans came off. Underwear.
He stripped quickly. His cock already hard. Thick.
When he settled between my legs, I watched him.
His hand didn’t reach for the drawer.
No pause. No condom wrapper being torn open.
Just him. Positioning himself at my entrance.
He looked at me. Question in his eyes.
I nodded.
He pushed inside. Slow. Careful.
The stretch took a moment. His girth always did. I breathed through it.
“Okay?”
“Yeah.”
He started moving. Careful at first. Then deeper.
I watched his face. Something was different.
The tightness in his jaw—gone. The careful control—loosening.
His eyes closed. Mouth falling open slightly.
“God,” he breathed. “You feel—”
He didn’t finish. Just moved faster.
It felt different for me too. More friction. More heat. Wetter. Slicker.
No barrier. Just him inside me.
His hands gripped my hips. Pulling me against him with each thrust.
The fullness was overwhelming. His cock stretching me. Filling every inch.
“Fuck—” he gasped. “I forgot—I forgot how good—”
His rhythm broke. Got harder. More urgent.
I could feel him swelling. Getting thicker. Right on the edge.
“Vic—” His voice wrecked. “I’m gonna—”
“Do it.”
He buried himself deep. As deep as he could go.
Then I felt it.
His cock pulsing. Once. Hard.
Heat flooding. Sudden. Intense.
Another pulse. More heat. Spreading.
Again. And again.
He was shaking. Gasping against my neck.
Each pulse I felt distinctly. The throb of his cock. The jet of cum.
Hot. Thick. So much.
It kept coming. Pulse after pulse. Flooding me. Filling me.
More than I remembered. More than Vegas.
Finally the pulsing slowed. Stopped.
He collapsed on top of me. Both of us breathing hard.
Didn’t pull out. Just stayed buried inside me. Making sure it all stayed.
“Fuck,” he whispered finally. “I—fuck.”
I felt it inside me. His cum. Heavy. Warm. So much of it.
When he finally pulled out, I felt it immediately. The emptiness. Then the flood.
Wetness rushing out. Too much to hold. Running down between my legs. Onto the couch.
He was watching. Eyes fixed on where we’d been connected. On his cum leaking out of me.
“Jesus,” he whispered. “Look at you.”
My face got hot.
He reached down. Fingers sliding through the wetness. Then pushing it back inside me.
I gasped.
“Shh.” He did it again. “Just—want to keep it in.”
Intimate. Possessive.
When he was satisfied, he helped me sit up. More wetness leaked immediately. I felt it running down my thighs.
“I’m going to be leaking all night.”
He smiled. Actually smiled. “Yeah. You are.”
“That’s not—” I stopped. Felt my face burning.
“Not what?”
“Nothing.”
But he was still smiling. Something lighter in his expression than I’d seen in months.
“Come on. Let’s get you cleaned up before your mom gets home.”
In the bathroom I cleaned myself up. Used half a roll of toilet paper trying to get it all out.
It kept coming. Every time I thought I was done, more would leak.
I gave up eventually. Just put on clean underwear. Knew they’d be soaked again in an hour.
When I came out, Dad was sitting on the couch. Dressed. Looking at me.
“You okay?”
“Yeah.”
“You sure?”
“Yeah. Just—” I gestured vaguely. “It’s a lot.”
“I know.”
“Are you okay?”
“Yeah.” He stood. Pulled me close. “Thank you.”
“For what?”
“For trusting me. For—” He stopped. “For this.”
His arms around me felt different. Less tense. Less careful. Like something that had been wound tight for months finally loosened.
“We’ll be smart about it. Stay in safe days. I promise.”
“Okay.”
“I mean it, Vic.”
“I know.”
We stayed like that until we heard Mom’s car in the driveway.
I woke up the next morning to wet underwear.
Not period. Just—him. Still leaking.
I changed them. Put on fresh ones.
An hour later, same thing. Soaked through.
I changed again.
Started to understand: this was going to be constant. At least for the next day or two.
I went downstairs. Mom was already at the table. Coffee in hand.
“Morning, honey.”
“Morning.”
I grabbed cereal. Sat down.
