My naughty sisters payback while I slept

It’s a quiet Friday night, and the house feels strangely significant without Mom and Dad. I lounge on the couch in my favourite plaid PJ bottoms, flipping through a stack of old DVDs. My sister Sara strolls into the living room wearing that red nightie Mom got for Christmas. It’s a bit flashy for a movie night, but that’s Sara for you.

“Found the popcorn!” she announces, holding up a bag like she’s discovered treasure.

“Excellent. Movie night can’t happen without it,” I reply.

She flops down beside me. “So, what are we watching?”

I hold up two options. “We’ve got ‘Space Ninjas’ or ‘Zombie Pirates.’ Choose your cheesy adventure.”

She laughs. “Ugh, both sound equally terrible. Let’s go with ‘Space Ninjas.’ At least ninjas are cool.”

As the movie starts, she nudges me. “Hey, think Dad would notice if we borrowed some of his ‘special’ soda?”

I raise an eyebrow. “You mean the kind that’s not soda?”

She grins mischievously. “Exactly.”

“Well, he did say to make ourselves home,” I shrug.

A few minutes later, we’re back on the couch, glasses in hand. “To irresponsible decisions,” I toast.

“Cheers!” she giggles.

We get through the movie’s first half, laughing at the ridiculous fight scenes. “I don’t think that’s how zero gravity works,” Sara points out as a ninja does a backflip in space.

“Pretty sure physics took a vacation on this one,” I agree.

The snacks disappear quickly, and the ‘special’ soda seems to refill itself. By the time the credits roll, we’re both in fits of laughter over the absurd ending.

“Well, that was a cinematic masterpiece,” I declare.

Sara stretches and nearly knocks over her glass. “Whoops! Maybe I’ve had enough of Dad’s soda.”

“Agreed. Wouldn’t want you spilling secrets,” I tease.

She sticks out her tongue. “My secrets are safe.”

“Only one secret I’ll tell you: I like sleep sex,” she grinned. “My boyfriend Daniel always uses me in my sleep. My idea is that I told him to wait until I was asleep.”

“Jeez, sis, too much information,” I said, and my cock became hard at the thought of someone fucking her in her sleep.

“But seriously, it’s so hot when he does that. I wake up feeling all warm and satisfied,” Sara continues, utterly unaware of my arousal.

I try to hide my erection by crossing my legs. “Uh-huh.”

She giggles again, clueless about the effect she’s having on me. “Don’t tell Mom and Dad though! They might disapprove.”

“Definitely won’t tell them,” I assure her, still struggling to control my cock that is now throbbing in my PJ bottoms. The thought of Sara being used while asleep is driving me crazy with lust. My mind races with dirty thoughts as I imagine myself sneaking into her room at night and sliding inside her tight little pussy without waking her up.

I glance at the clock. “Wow, it’s way past midnight.”

She yawns. “No wonder I’m so sleepy.”

I look over to see her eyelids drooping. “Think it’s bedtime for you.”

“Nah, I’m just resting my eyes,” she mumbles.

A few moments later, she’s fast asleep, snuggled into the corner of the couch. I shake my head, smiling. “You always were the lightweight.”

I stand up and walk over carefully. “Alright, Sleeping Beauty, let’s get you to bed.”

I gently lift her, surprised at how light she feels. “Guess all that yoga paid off,” I whisper.

She murmurs something unintelligible as I carry her down the hall. Pushing open her bedroom door with my foot, I navigate the obstacle course of clothes and shoes on her floor.

“Really need to clean this room,” I mutter.

I lay her down on her bed and pull the covers over her. She sighs contentedly. “Night, Jake,” she whispers, half-asleep.

“Goodnight, Sara,” I reply softly.

I went and cleaned up the living room. As time knocked on before going to bed, I checked on her. Her ass was hanging off the bed, and the covers were off slightly. Her nightie was ridden up, showing her panties, which barely covered her private area.

I suddenly got a hard-on; I went to put her back in bed. But I didn’t; I stood beside the bed next to her ass. She was on her side sleeping. I wondered what her pussy looked like, it was darkish in her room, but I could see just a bit.

I knelt down and gently parted her panties to the side. I felt her pussy. It felt so good; I kissed it and gave it a gentle lick. What am I doing? My cock was solid hard now.

I stood up and took out my cock, and stroked it; I then couldn’t believe what I was doing. I stood closer and pushed the head of my cock into her pussy. I held her ass and slowly thrust into her pussy, I was side fucking her pussy.

She let out a whimper but didn’t wake up, oh fuck it felt so good.

I continue to thrust softly, each movement sending jolts of pleasure coursing through me. It’s wrong, yet I can’t seem to stop. My cock sinks deeper into her warmth, and I wrap an arm around her waist to steady myself. She stirs slightly, a soft moan escaping her lips as she subconsciously pushes back against me.

I go faster as I feel like I am going to explode, as my cock slides in and out of her well-kept, clean pussy. It wouldn’t be clean soon, as I was about to make it a swampy mess.

I groan and thrust harder, feeling her pussy walls tighten around me. She mumbles something incoherent, but it doesn’t stop me. I’m lost in the sensation of taking what I want without caring about the consequences.

Suddenly, she lets out a loud moan and her body tense up. I feel a rush of pleasure as I release myself inside her, my seed filling her up.

I pull out, feeling a mix of guilt and satisfaction wash over me. I quickly clean myself up and tuck my cock away before tiptoeing out of the room.

As I lay in bed, trying to sleep, I can’t help but wonder if she’ll ever find out what I did.

At 9:23 AM, I woke up to a warm sensation on my lower half. As I slowly opened my eyes, I saw my sister Sara’s head bobbing up and down rhythmically. At first, I thought I was still dreaming, but then reality hit me like a ton of bricks.

“Sara! What the hell are you doing?” I exclaimed, trying to push her away.

But she didn’t budge. Instead, she looked up at me with a mischievous grin and said, “This is payback for what you did to me last night, you perve.”

Confusion washed over me as I tried to remember if I had done anything inappropriate to her the previous night. “What are you talking about? I didn’t do anything to you!” I protested.

Sara raised an eyebrow and said, “Oh, really? You don’t remember sneaking into my room while I was sleeping and fondling my breasts? Oh, and then fucking my pussy.”

My face turned bright red as I realized that I must have been sleepwalking and had done exactly what she accused me of. “I’m so sorry, Sara. I didn’t mean to do that. I must have been sleepwalking,” I stammered.

Sara shrugged and said, “Sleepwalking, bullshite. Well, now we’re even. I always wondered what it would feel like to have you inside my mouth, and now I know. Now shut the fuck up, and let me get on with it.”

I couldn’t believe what was happening. My sister was giving me a blowjob, and she seemed to be enjoying it just as much as I was. I tried to push down the guilt and shame I felt and just focused on the pleasure coursing through my body.

Sara’s lips were soft and warm, and her tongue swirled around my shaft with expert precision. She knew exactly how to drive me wild, and before long, I could feel the familiar tingling sensation building in my balls.

“I’m gonna cum, Sara,” I warned her, but she just redoubled her efforts, taking me deeper into her mouth than ever before.

With a final thrust, I exploded into her mouth, filling it with wave after wave of hot, sticky semen. Sara swallowed every drop, never breaking eye contact with me.

As we both lay there, panting and trying to catch our breath, I couldn’t help but feel a strange mix of emotions. On the one hand, I was horrified at what had just happened between us. On the other hand, I couldn’t deny the fact that it had felt incredible – better than any blowjob I had ever received before.

“I guess we’re even now,” Sara said with a satisfied smile, and I couldn’t help but agree.
