"Babe, I'm almost home, so I'm going to let you go. I'll call you in the morning, but have a great time with your family. Can't wait to see you in three weeks. Love you." I hung up with Jessica and pulled into my parent's driveway at about midnight. The trip home from college was a long drive, and I was thrilled to be finished with it. My little sister's car was parked next to my mom's. She must have decided to come home for winter break a day early. The house glowed with white light - dad's Christmas cheer always put his house at the top of the block's list of decorated homes. I grabbed my bags out of the trunk and quietly made my way inside, making sure not to wake the family.

All the lights were off in the house, except for the glow of the Christmas tree, twinkling in the living room. I passed through the kitchen on my way upstairs and snagged a couple of dad's beers. As I quietly made my way up the stairs, the gentlest of sounds could be heard of the utter silence in the house. It was coming from my sister's room, which leaked light from under the door. She was still up. I thought I'd pop in and say hello, but as I approached the door, the sound became much more clear. She was masturbating. Holy shit, I thought to myself. I didn't know Kelly masturbated! She was a dorky theater kid. Although, I considered, maybe that makes all the more sense then.

I gently made my way into my room with a devious plan. Our rooms were connected by a shared bathroom, and I supposed I might see if her bathroom door was open and I might be able to catch a glimpse of this event. I softly opened my bedroom door and walked into a dark room that was only disturbed by a faint glow of light coming through the open bathroom door. I might luck out! I put my bag down and snuck into the bathroom. The door on her end was open halfway, so I tiptoed across the bathroom, from my end to hers and sneakily peeked around the door frame.

Kelly was sitting up in her bed, naked from the waist down, with her shirt bunched up over her breasts. Holy shit, I thought to myself, Kelly is kind of hot now. But beyond her breasts, which had grown to a serious C or D cup, and beyond her gorgeous legs leading up to a very naughty little bush, what really blew my mind was what Kelly was doing. She was fingering herself with her right hand, and filming herself doing it with her left! Who is she sending this to, I asked myself. She must have found herself a little boyfriend in her first semester of college. Good for her.

She picked up the speed of her thrusting her fingers into herself, moaning as she did, until he brought herself to an orgasm and quickly pulled her fingers out and redirected them onto her clit. She vigorously rubbed herself while she squirted out a couple spurts of liquid. Wow, I thought to myself, she really knows what she's doing. She took a moment to collect herself, then brought her attention back to her phone. She clicked and clacked away at it, and then sent off whatever she had just typed. Her phone made a very unique "pa-ping" sound - a notification sound I had not ever heard before. She flung her phone across the bed and began to get up, presumably to come to the bathroom to wash her hands.

I quickly snuck back into my room, quietly closed my side of the bathroom door and settled into my room. The bathroom lights flicked on, the sink started running water, and a smirk found its way to the corner of my mouth.

I slept in the following morning and woke up with massive morning wood following a night's worth of sexual dreams. I got up and folded myself over the toilet, fighting my erection to unload my bladder.

"Honey, are you up yet?!" I heard my mom shout from downstairs, hearing me flush the toilet. "I've got breakfast for you and I'm taking you and Kelly shopping when she gets back from her run!"

"Thanks mom! Be right down!" I shouted.

As I washed my hands, I heard that familiar "pa-ping" sound come from Kelly's room. I cracked her door open and peeked inside. No Kelly. Just a quiet, empty room with Kelly's cell phone lit up on her bed. I crept over to it and looked at the notification. A black app icon with a red snake on it with the notification title "Kink Venom" sat on her lock screen with the preview message reading, "still thinking about that video you sent last..." and then it cut off. I quickly poked my head out of the doorway into the hall and looked around. The coast seemed clear.

I plugged in Kelly's predictable password into her phone: 0-0-0-0. Idiot. I jumped into the Kink Venom app. She was sending messages and pictures and videos back and forth to a user with the username "DingusDick6969". The messages were all sexual in nature and consisted of many "what I would do if I were there in person" type messages. Kelly seemed timid, but interested, following his demands to send various pictures and videos. I went into Kelly's profile and looked at her preferences. Her username was "TheFamilyVirgin" and her preferences were all around boys with brown hair, tall figures, athletic, Catholic and who liked to cook and eat copious amounts of italian food. Somewhat exactly how one would describe...me. There was a tab titled "Kinks" where Kelly had selected an array of interests from roleplay to public play, spanking to light BDSM, wax play to videoing play. And way down the list, hidden amongst her list of kinks, was a very interesting one: Incest.

I heard the front door open downstairs and Kelly shouted "Mom, I'm home!"

I threw the phone down on her bed and jumped back into my room. I headed downstairs and ran into Kelly in the hallway.

"Danny!" she shouted as she ran and jumped up anto me, wrapping her legs around me in a hugging embrace. "You're home! I missed you!"

"Missed you too sis. You're all sweaty..."

"Sorry" she laughed, climbing off me. "I'm about to jump in the shower. I'll see you downstairs."

As I sat and ate my breakfast and caught up with mom and dad, I was completely distracted by what I had found. This wasn't just a dating app, and this wasn't just a boyfriend. It was called Kink Venom for God's sake. My shy, innocent little sister clearly had a wild side - a suppressed one at that. I pulled out my phone and found the app in my app store. The thought crept into my mind slowly, and then all at once. I downloaded the app.

Kelly and I caught up as we meandered around the mall, various bags of christmas gifts in hand, our mom lost somewhere in the Macy's. I thought I might as well pry...gently.

"So...how has freshman year been treating you? Having fun at State?"

"It's ok," she replied timidly. "Most of my girlfriends rushed for sororities, which I didn't want to do, so it has felt a little lonely."

"What about boys?" I prodded, careful to not lay it on too hard.

"Oh my gosh, don't get me started. Zero boys. College boys are useless."

Interesting choice of words, I thought to myself. Not "pigs" or "stupid"...but useless. In what way?

"How do you mean?"

"You don't want to know about this stuff from your sister" she laughed.

"Try me."

"Well...they are just immature. All they want to do is get shitfaced at a frat house and then try to shove their soft dicks in you!" She giggled nervously, realizing she just said "soft dicks" to her brother.

I laughed and said, "So you've...you know...?"

"Oh my gosh, no. Gross. You know I'm not that type of girl."

"So you're still holding out for marriage huh?"

"No, I'm not like that anymore. I'm just holding out for the right guy. A serious guy. A guy I can trust and know will be with me forever. You know, like what you found with Jessica."

"Well maybe the frat houses aren't the place to find those guys. Have you tried dating apps?" I asked, almost shaking at the thought of her seeing right through me and knowing I snooped through her phone or something.

"No" she lied.

Mom came jogging up behind us, flailing her many bags around.

"Ok, I'm ready to leave!" she said.

We climbed in the car to leave the mall when I heard that familiar "pa-ping" come from Kelly's purse in the backseat.

"What was that?" I asked.

"Oh nothing" she quickly responded.

I could see her over my shoulder, alone in the backseat, huddled over her phone checking her latest Kink Venom message.

Later that night, I laid in bed, exploring the app. The general gist was that you'd build a profile of preferences and kinks, then you'd be given a deck of potential matches to sift through. Like Bumble, the girl made the first move. The difference with this app was, once you paired with a girl, it locked you out of other searches - meaning the only way to get back into the pool of options would be to end the conversation with that girl and lose her profile forever.

Why did I download this? While it sounded fun to connect with random kinky chicks, it wasn't like I was single. Jessica would lose her mind if she found out. The more I thought about it, and more honest I was with myself, the real reason I was setting up this account was because I could not get the image of my little sister's pussy gushing and squirting all over her bed...her incredible tits with her perky little nipples that almost made me salivate. I think...I wanted to see more. I started to fill out my profile. First, I needed a username. In keeping with my sister's theme, and trying to be a bit cheeky, I wrote in "BrothersAlwaysWatching". Next, I needed the perfect profile photo. Most of the accounts I saw were very risque, so I stripped down naked, stood in front of a mirror, flexed every muscle in my body, covered my cock with a Winnie the Pooh stuffie I grabbed off Kelly's bed, and took a neck down photo of myself, hiding my face from the app. She loved Winnie the Pooh, so I hoped that might catch her eye. It was a pretty sexy photo if I could say so myself. I kept very good care of myself and I always made sure to keep my body sculpted and hard.

I thought back to Kelly's profile and started filling out similar interests. How do I make sure I get paired with her, I wondered? I put in an age range, a location radius, fit girls, Catholic, Italian, etc. Then in the Kink tab, I tried to remember what she had. BDSM, spanking, roleplay, public play...what else? Oh yeah, how could I forget? Incest.

What did that mean? Was it that she liked incest porn? I've fancied a little family roleplay porn from time to time, but was it something deeper? Or was it that she thinks about me sexually? Or dad? I probably shouldn't judge her...even since spying on her the night prior, all I've been thinking about is my sister and her young, virgin body. My mind spiraled and before I knew it, I was fully erect, daydreaming about connecting with Kelly on Kink Venom, getting naughty pictures from her, and maybe even fucking my little sister. Holy shit.

Then the thought occurred to me. I can't match with Kelly! She's already matched with DingusDick6969! Shit, I thought. I was going to have to sneak into her phone again and delete him. But how could I do that with her not knowing? Maybe I could get away with her thinking the app malfunctioned? I stressed over this, as I heard a familiar sound coming from my sister's room through the Jack and Jill bathroom. "Pa-ping".

I walked into the hallway and quietly listened to the house. Mom and Kelly were downstairs by the tree watching a Christmas movie. I hurried down the stairs to make sure she hadn't left mom and gone back up to her room. There she was, passed out on the couch. This was my moment. I rushed back upstairs, grabbed Kelly's phone off her desk, pounded 0-0-0-0...idiot...and jumped into her Kink Venom account. A new message from DingusDick6969 read, "oh baby i want to unwrap you christmas morning and fill you to the brim".

"Goodbye Dingus" I found myself audibly saying to myself as I navigated to his profile and hit "Delete Match". And just like that, he was gone. Her app reverted to a deck of options for her to sift through. Now I just just had to hope she'd find me.

I rushed back into my room and grabbed my phone. I updated the deck and started sifting through it, denying everyone that wasn't Kelly. Profile after profile, no Kelly. I was starting to lose hope when all of sudden, there she was. "TheFamilyVirgin" looking me dead in the eyes. She was laying in her dorm room bed wearing nothing but some lacy white panties and covering her breasts with her arm. An erotic photo that sent me over the edge. I didn't even realize how rock hard I had become. I carefully gave her a "swipe right" and tossed her card into my "Like" column.

Now all that was left to do was wait.

- - - - - - - - - -

The next morning was Christmas eve. Kelly and I were lounging in the living room by the tree watching National Lampoon's Christmas Vacation with dad. Mom was in the kitching getting started on her Christmas eve feast. I looked over at Kelly who was sitting opposite dad on the couch, fiddling with her phone. She seemed down.

"You ok sis?" I asked.

"I'm fine" she said, perfectly normally, then redirected her attention back to her phone.

I could tell she was upset, and likely about losing her little fling on that app. I could see her scrolling on her phone, her thumb continuing to swipe left again and again. She must be on the app, I thought. She was guarding her phone's screen angle from dad, which meant she didn't want anyone to see what she was doing, but I knew. Then she paused and leaned into her phone a tiny bit. Was she reading something? She was staring intently. Then, in an almost "huh, might as well" motion, she swiped her thumb to the right.

Bzzzz bzzzz

I felt my phone vibrate in my pocket. I lit up with energy. Did she just do what I think she just did? I slowly pulled out my phone and held it in my lap where no one had an angle to see it. A Kink Venom notification lit up my lock screen with the words "You have a match!" Kelly was the only profile I "liked", so it would have to be her, right? I slowly opened my phone and there it was - her photo and my photo paired together on the app screen like two cards being dealt in Texas Hold 'Em. I did it. Now what?

I opened the messenger tool and began to type. I decided to go straight in with the incest theme. Why dance around it with cute messages? Hit her hard!

:::Hey there FamilyVirgin. Looks like we share a ton of interests on KV. Did you match with BrothersAlwaysWatching because you're a naughty little virgin who needs her big brother to help her?:::

"Pa-ping" - Kelly quickly silenced her phone. She read the message while I peered out of the corner of my eye, pretending to watch the movie. She looked up at my dad and me and made sure she was in the clear before typing back...

:::You have no idea big brother:::

Holy shit. What kind of repressed sexual frustration was this girl going through? I couldn't believe my plan worked. I had her in the palm of my hand. My brain went down the rabbit hole of all the fun I was going to have with this.

:::So are you really a virgin?:::

:::Unfortunately:::

:::Well we'll have to fix that:::

:::We'll see. I'm looking for Mr. Right:::

:::So what do I call you? Little sister?:::

:::I'm Kelly:::

Oh sis...what a rookie move. I couldn't believe she would put her real name on this app!

:::Nice to meet you Kelly. I'm Drew:::

:::Hi Drew :):::

I was in. I wasn't sure how fast I'd be able to move her towards sending me nudes, but I was excited to keep this game moving along.

:::I love your profile picture. I can't believe how sexy my little sister is:::

A moment went by and then a response. Kelly sent a photo she must have had stored on her phone of her taking a picture of herself in the mirror in the upstairs bathroom. She was topless, throwing up a peace sign and smiling at the camera. Her boobs were so perfect. Perfectly shaped, perfectly sized, not too small, not aggressively massive, elegant yet sexy. I immediately compared them to Jessica's - tiny A cup titties with little nipples. Kelly's photo was accompanied by a message that read,

:::How do you like these big brother?:::

I adjusted my cock, trying to slyly hide my erection from my dad and sister. I grabbed a blanket that was hanging off the back of the chair and made sure to cover up.

:::I don't think I've ever seen a better set of tits than that. You just made me rock hard little sis. Naughty naughty:::

:::Oh did I? Let me see:::

What the fuck? If you knew Kelly, you would understand how out of character this was for her. She was a sweet girl. A virgin, book smart, religious, always wearing her cross necklace...not the type of girl you'd find on a fetish dating app sending nudes to complete strangers. I think all those years in high school of watching all her friends have fun while she studied and rehearsed lines for the plays caught up to her in college. Here she is, on her own, no parents to hover over her or lay down rules...letting loose. Good for her.

"I'm gonna take a shower" I announced as I quickly ran upstairs to my room. I needed some privacy.

I sat on the edge of the bed and pulled my cock out of my sweatpants. It throbbed with anticipation, insanity and an unbelievable pit in my stomach of what could go wrong. I opened the app and snapped a picture of my cock in my hand. I was proud of its size. Not porn-massive, but definitely a sizable member. Never met a girl that wasn't satisfied. I fired off the photo.

:::See what you've done?:::

:::woah...:::

I saw Dingus's cock in her phone, and mine certainly outshined his, thank god. I loved her response. The thought of my sister downstairs opening her phone to see a dick pic from some new fling on her dating app, not knowing she was salivating over her real brother's cock...I was in tunnel vision.

:::Ok, I show you mine, you show me yours, eh sis?:::

Almost instantly after sending that message, I heard Kelly's feet running up the stairs and her closing the door to her room.

"Danny, are you taking a shower?" she yelled through the Jack and Jill.

"Uh yeah. Hopping in now!"

I moved into the bathroom and turned on the shower. As I did, she closed her door to the bathroom thinking she was giving ME privacy. But I knew she wanted privacy of her own. I sat on the edge of the tub while the shower ran, looking at my phone, waiting for her response.

:::Are you sure big brother?:::

:::As long as you don't tell mom and dad::: I pinged back, keeping this incestuous theme going.

And there it was. A photo popped up in the app of Kelly's legs spread. Her middle finger and pointer finger in an upside down V, pulling her pussy lips apart. In the background, she was biting her finger looking down at the camera. Holy shit. Kelly is wild!

:::Damn little sis...I want to taste those lips:::

I couldn't take my eyes off her pussy on my phone. I was transfixed. I held my phone in one hand and stroked my cocked in the other. Before I could really get started, my phone buzzed again.

:::Here's a little Christmas eve gift for you::: followed by a video of her wrapping her lips around a large purple dildo, sucking it up and down and licking it from the base of the shaft, to the tip. Then she lowered the dildo, and her phone, down to her pussy and started teasing her clit with it. Finally, she slipped it inside her tight little hole, gave it a few pumps, then pulled it out and sucked it again, licking up her own taste off the toy. :::I taste good:::

I felt compelled to send her a video of me stroking to her, but I quickly realized I couldn't send her a video of me with the shower going in the background...in a bathroom she would 100% recognize. I snuck into my room and threw a towel over my bed. I then filmed myself jerking off, slowly stroking my hard cock over the towel. I didn't think twice - I sent it off.
