I Made a Sex Video With My Wife’s Younger Sister

She didn’t give me any choice.

A week had passed since I spied on my wife’s sister playing with herself. She caught me watching and ended up jerking me off over her panties.

“How long do you think she’ll still be here?” I asked my wife.

“Go to sleep. It’s still early,” she mumbled next to me in bed.

“She hasn’t come out of that room in days,” I said.

I wanted the temptation gone. Last time went too far already.

“Hey,” I said in a lower voice.

I ran my hand over my wife’s thigh and groped her bum.

“It’s Sunday morning, Andrew. Let me lie in a bit,” she grumbled again. “Go check on Katie, make her a coffee or something.”

I sighed and rolled out of bed. I waited for my erection to subside before getting up.

“I’m tired of getting dressed in my own house,” I complained.

“Just leave your boxers on. Katie doesn’t care. She’s half your age, Andrew,” Jade said.

If only she knew.

I jogged downstairs, wearing only my boxers.

“Katie?” I said, knocking.

No response.

“Katie? Are you okay in there?” I asked.

“Come in,” she called from inside.

I opened the door and stepped inside.

“What the hell?” I said, looking around.

She had ring lights and LED strips all over the room. Katie had a tripod set up with her phone perched on top.

“I’m doing live streams again,” she said.

“What kind of live streams?” I said, looking at her underwear all over the bed.

“The sexy kind,” she grinned.

My eyes moved back to where Katie was on the bed. I’d only now noticed she was wearing a see-through white babydoll and tiny white panties. Her dark nipples shone through the sheer material. I tried hard not to get hard. And failed. Of course, Katie noticed instantly.

“Is my big sis not taking care of you?” she said, staring at my tenting boxers.

I pushed the front down.

“I don’t want you doing this here,” I said.

“You can watch if you want,” Katie said.

Before I could respond, she bounced on the bed, her eyes filled with excitement.

“Ooh, ooh, I have such a good idea!” she said.

“Do I want to know?” I said.

“So, I read this super-hot erotic story about a dad who catches the babysitter stealing. And she begs him not to tell the police. And they end up fucking while the wife watches!”

“Where are you going with this?” I said.

“Well, we probably won’t be able to get big sis on board as the cuckold. But can we play the dad/babysitter role?” she said.

“You are out of your fucking mind, Katie,” I said.

“I jerked you off, and you came on my panties, Andrew. You can do this for me,” she said.

Was that a threat?

“Don’t worry. It won’t be live in case you get stage fright. I’ll make a regular movie,” Katie said.

A sex movie with my wife’s younger sister? Was I losing my mind?

“Not a chance. I’m going back upstairs,” I said.

Katie leaned forward and pressed on her phone before turning to me.

“Please, sir, don’t call the cops on me. I’ll do anything,” she said, remembering a line from the story.

Katie looked slutty and innocent at the same time. Her nipples looked darker and harder than before. She bit her bottom lip and lowered her head a little.

“Anything, you say?” I said, trying to sound natural.

“You can fuck my nasty mouth, sir,” she said, opening wide.

My cock was throbbing inside my boxers. I listened outside the bedroom door before closing it. Jade was still asleep.

“Then take my whole dick in your mouth, you thieving little, uh, whore,” I blurted out.

Katie seemed impressed as she wrapped her pink lips around my engorged tip.

“Hmmm,” I moaned, feeling my young sister-in-law’s warm mouth around my cock.

I grabbed a handful of her hair and started fucking her face. She sputtered and gagged as I shoved my cock as deep as it could go.

Owp! Owp! Owp!

Finally, I yanked her head off. She wiped tears from her cheeks, gasping for breath. Jesus, what was I doing? I was ready to walk out. This was ridiculous.

“Is that all you want, sir? I really don’t want you to call the cops,” Katie said.

She was still into it. Katie leaned back on the bed and spread her legs. She used a finger and pulled the flimsy front of her panties to the side. Her smooth, nubile cunt lips stared back at me.

“My cunny is wet and throbbing,” she said.

Katie ran her hands over her chest.

“And my titties are aching to be touched,” she cooed.

I lunged forward, sinking my fingers into her soft boobs. I tugged on her nipples, before pulling the teddy open to wrap my lips around her soft buds.

“Ah,” she cried out.

“It’s better if I’m on top for the movie,” she whispered in my ear, before pushing me onto my back.

“I disagree,” I said.

I spun her around onto her stomach. She yelped as I pulled her ass up and smacked her soft cheeks. I used my thumbs to pull her cheeks open, staring at her messy opening. A moment later, I forced my rock-hard cock deep into her gripping pussy.

“Ah!” she cried out.

I could feel I was stretching her college cunt wide. I pushed Katie down onto the bed and fucked her prone bone. Her body bounced up against mine with each vicious thrust.

“Ah, ah, ah!” she whined.

Flup! Flup! Flup!

“Take it all, you cum-slut,” I said through gritted teeth.

The next moment I exploded, flooding my young sister-in-law’s fertile womb with my creamy seed. I pounded her for a few more seconds, before pulling out with a squelch.

Katie rolled onto her back and opened her legs for the camera. She parted her pussy lips and squeezed, watching in glee as my cum oozed out of her ravaged opening. My wife’s sister stared at me with lust in her eyes. I could see she loved my darker side. A side I’d forgotten about for years.

“I hope you didn’t make me pregnant, sir,” she said.

My heart dropped.

“This is still part of the movie, right?” I whispered.

She only smiled.

“RIGHT?!”

The first time my sister-in-law seduced me:
