Our Quarantine Story [MF] [Sister] (Fiction)

This story is 100% fiction, the characters aren’t directly based on real people and none of this actually happened. I hope that you guys enjoy this story as much as I do!

–

My little sister (Kayla, 19F) and I (Jake, 22M) have been living together since August 2019. We’re both students at the same university, where I’m a junior physics major and she’s a freshman economics major. She and I have always gotten along, so when she got accepted into my university deciding to live together was a no-brainer! After 2 years of annoying roommates, living with her has been a breath of fresh air. We share a 2 bed 2 bath apartment about 3 blocks from campus.

To give you an idea of what she looks like, Kayla is a thin (not super thin, slightly chubby but still thin) 5’6 blonde girl with green eyes, C cup breasts, and a pretty nice butt. And I’m a pretty average looking semi-muscular 5’10 guy with brown hair and brown eyes. We love each other very much- as brother and sister, nothing overtly sexual has ever happened between us. The only kinda NSFW thing we’ve ever done is share laundry, so I have touched her clothes including bras and panties. We live a normal life of studying, playing games, watching movies, having friends over, and all that wholesome stuff.

But then, the pandemic changed our lives. The university announced during spring break that the campus would be closed and all classes would be switched online. The state government announced a quarantine, so for the past two months it’s just been me, my sis, and a 2 bedroom apartment.

For the first week or so, things were surprisingly normal. The shift to online classes wasn’t as bad as we were expecting, I would go to the grocery store once a week, and delivery was available whenever we wanted. At first we tried to stay in touch with friends and family over Skype and FaceTime, but at the end of the day we had each other and that was enough.

By week 2 of quarantine, I noticed that Kayla had stopped wearing bras. I tried not to notice her big boobs and nipples poking through, but I was… excited, by this recent development. As we got more and more comfy just the two of us, pants became shorts and shorts became underwear. By the time it was April, both of us were just hanging around in just our shirts and underwear.

One night we were playing games on my PS4, sitting on the couch together. After a few hours we decided to order Chipotle and watch a movie (Happy Death Day) and she brought over her blanket to get comfy. It was one of those really nice soft and fuzzy blankets.

“Do you wanna share?” she asked regarding the blanket.

“Oh, sure, but is it big enough for both of us?” I asked.

“Yeah definitely, it’s huge! Take some.” She put the blanket over me and we snuggled up to the movie.

For the first time in months, I was physically intimate with a girl. She put her head on my shoulder and I could feel her sideboob through her shirt. My heartbeat was rising and before I knew it, for the first time in my life, I was hard for my sister. Kayla presumably never noticed and luckily I went soft before the movie ended and we went to bed.

Laying in bed that night, I couldn’t stop thinking about it. How she felt, how she smelled, being so close to her, how warm she was. I tried to resist and felt so ashamed of myself, but before I knew it I was masturbating to my sister. I woke up the next morning and decided that *obviously* nothing could happen between us. She was my sister, my roommate, my parents’ daughter, and if I tried anything then only chaos would result.

Things immediately went back to normal, and really nothing had ever changed between us in the first place. But a few days later something did happen. While we were talking about classes or something I noticed the curves showing through Kayla’s shirt and how I could see the imprint of her nipples. I tried to control it, thought about hiding it, but it was too late, I was rock hard in front of her.

“Woah, where did that python come from!?” she exclaimed chuckling and blushing.

I was so shocked and afraid that I couldn’t think straight. “Kayl- I’m sorry I- it’s just I-“

“Dude, no worries, I know how it is for guys. Don’t even worry about it.” Kayla changed the subject and I was so relieved that she didn’t freak out or call me a pervert or something.

The best part of quarantine has been the quality time with my sister. Our classes have been hard, but other than that nothing matters anymore. It doesn’t matter what we do, it doesn’t matter who we’re with, it doesn’t matter how we look, it’s just the two of us living our lives together.

But the worst part of quarantine has been my weight gain. My muscles have faded and been replaced with 10 pounds of fat. On Sunday, May 3rd I asked her if she could help me lose weight. We came up with a meal plan where she would ration out food for me, which would also help us save money on food.

“Thank you so much for helping me with this!” I said giving her boo- I mean giving her a hug.

“No problem!” Kayla smiled. “But honestly, don’t worry so much about how you look. You haven’t gained *that* much weight, and everyone is putting on a few pounds during quarantine.”

“But… I’ve never been fat before. I’m starting to get moobs, and my muscles are going away.”

“Jake, I promise you look fine. And once this is all over I’ll drag you right back to the gym!” We both laughed at that.

But I was still sad. She just didn’t get it. “Can I show you? Would you be offended if I took my shirt off?”

“No, I’m not a prude.” she said.

I took my shirt off, standing before her in nothing but my underwear.

“Honestly that’s not bad,” she assured me, “you’re still thinner than half the guys I know.”

“Thanks Kayla” I said feeling genuinely better. I thought about putting my shirt back on, but honestly this felt better, and it’s not like I had a problem having less clothes on around her.

But, I wasn’t prepared for what happened the next morning. I came out of the bedroom in my underwear and saw my sister making breakfast- topless. I was shocked, unable to stop myself from staring at her breasts before jolting my head away a few seconds later. She was acting totally normal about this, so I decided to just play along with it. After all, I was walking around without a shirt so why not her too?

So there we were, two siblings sharing an apartment in nothing but my underwear and her panties. Her boobs were the most amazing thing I’d ever seen, but I wasn’t going to ruin this by making her uncomfortable. As finals week came we spent most of our time studying and only a little bit of time hanging out. The exams were taking a toll on Kayla’s mental health, so I helped her study as much as I could.

On Monday night, we both took our last final exams online (electromagnetism for me, integral calculus for her). After I finished my exam, I walked out of my bedroom and breathed a sigh of relief. A few minutes later she came out too, looking just as exhausted as I was. My brain was too fried to not look at her tits, but I made it look like I was just looking in her general direction.

“How did you do?” she asked me in a monotone voice.

“I think I did okay, definitely an A or a B. What about you?”

She looked very perturbed and hesitated. “I don’t know. It’s whatever. I just.. can’t fail this, no calculus means I have to change majors… can I have a hug?”

“Of course!” I said trying to sound sympathetic and comforting. For the first time I made contact with my sister’s bare breasts. My dick went right up, but she was either too tired to notice or too tired to care.

“Goodnight, I love you.” she said still distraught.

“I love you too, Kayla! If you need anything just let me know.” She turned around and went to bed, apparently not noticing how hard I was. I tried to sleep that night, but I was just laying there trying not to fap.

*Okay fine,* I thought to myself, I had to jerk off, but I wasn’t going to think about my sister again. I went on to PornHub to try and find something, but I didn’t care about any of these stupid videos. I had to find something, but I couldn’t. I then submitted, fapped to the thought of Kayla and fell asleep.

I woke up yesterday morning trying to forget about last night. I took a shower, put on some underwear, and exited my bedroom.

“Hey, you’re up!!” Kayla ran up to me and gave me a squeeze hug and a kiss on the cheek.

“Wow, someone’s happy! Are grades in yet?” I asked her.

“No, but who cares!? We’re done, it’s summer vacation! We need to celebrate!!” And so we did!

Yesterday was our party day. We ordered 2 large pizzas, pasta, cheese sticks, and salads. The doorbell rang 40 minutes later, so Kayla put on a shirt and brought in the food. She then took off her shirt and waved it around like a stripper and couldn’t stop laughing.

I haven’t seen Kayla this happy in a long time, but I wasn’t sure how genuine this euphoria really was. Still, if she was happy then I was happy. We ate, listened to music, danced (those boobs sure could shake..), sang badly, played games, and had the time of our lives together.

At around 11 PM I told her that I was getting tired and we should pick up tomorrow.

“Oh..” she said as the euphoria started to fade. “Yeah time for bed. I had so much fun today!”

“Yeah, me too! Goodnight sis!” and so we parted and went to bed.

Last night I got in bed, saw a few YouTube videos, and then decided it was time for sleep. But then I heard knocking on the door.

“Oh, uh, yeah what is it?”

“Jake! Jake.. can I come in??”

I was shocked and confused. “Yeah, sure come in.”

Kayla opened the door and came up to me in tears. She was having a panic attack. “I can’t do this anymore, I’m going to fail, I just know I am. I can never do anything right, I’m just bad at everything!”

“No, no, it’s okay, you’re going to be okay! You’re just scared, it’s going to be okay!”

She continued sobbing by my bed. “No, it’s not okay. You don’t get it, I’m not smart, I don’t know what I’m doing, I can’t do anything!”

I gave her some of my water, which did help her calm down.

“Can I stay with you tonight?” she asked after regaining her composure.

“Uh, I, yeah- it’s just.. I’m not wearing anything, is that okay?”

“I don’t care, I just can’t be alone tonight.” She got in the bed with me, I fully nude and her just wearing panties.

I spooned her for a while, trying to make her feel better. I rubbed her belly for a bit, and once again was hard for my sister. My penis touched the back of her leg, and she moved in closer to me.

I should have just left it at that, but in my horny stupidity I started touching her boobs.

“Is this okay?” I asked her.

“Yeah, yeah that’s good.” Her nipples were hard, and her breasts just felt so perfect, so soft and firm. She started breathing faster and moaning. She turned around we started to make out.

“Do you have any condoms?” she asked.

“Yeah, yeah- uh” I reached into my drawer and pulled out some old condoms. I put one on and pulled off her soaked pink panties. I got on top of her, kissed her for a few more minutes, and we made love.

I took Kayla’s virginity last night. We thrusted and kissed for what must have felt like hours, traded positions, fucked some more, felt each other while I sucked on her boobs, and after we finished having sex we fell asleep in each other’s arms.

So, that’s where we are now. We talked about it in the morning, and we decided that as long as we love each other, it doesn’t matter what kind of love we share. We don’t know what’s going on, how we’re going to deal with it, if we can ever tell anyone, but all that matters is that we love each other. I don’t know how things will be for us going forward, but I do know that sleeping with my sister was the best experience of my life.
