obsession

It all started a few years ago just after i turned seventeen,

My sister who is younger than me by two and a half years fell in with the wrong friend group, and she caved into peer pressure, real fast, and really easy, which was bad for her, but fun for me. as a regular girl of her age, she was pressured into dressing a certain way, into dressing in a sexual way, tricked into not wearing panties when going places like her friends never did, and also, tricked into flashing people also for fun.

I noticed she had a private snapchat group, that her and her friends would show off on, and allow others who joined to see as well. One time she left her phone laying around the house and i managed to open it and get the snapchat group name so i can join. And waw, when i joined. Over the next week i never masturbated so much in my life, seeing my sister naked, watching videos seeing photos of her in public places while her friends took videos and photos of her opening her legs, playing with her pussy, and they all did the same, for the fun of it.

I noticed they had challenges in their story mode, clicking on it, was even more mind blowing, there was videos of these younger girls giving blowjobs to random people, while secretly filming themselves. As well as some of the girls having sex. It seems like my sister has not for filled this challenge yet, there was a few videos of her sucking dick and swallowing loads, from these older men, not even boys. But men. But it seems like none of her fucking yet.

As a random on their snapchat group, neither my sister or her friends knew i was there watching everything, i suggested to her, she should go to a party with a costume, and let some random guy fuck her, it took a few hours to get a reply but one of her friends said that was a great idea, i also suggested, she should not wear anything under her costume, no bra no panties at all, there was laughing emojis sent with agreement from the other girls, they told her to do it, and she reluctantly agreed.

The party she got invited too was a local one, she and her friends all were going, so she and her friends had been shopping for slutty outfits, she had left her outfit in her room and went out with her friends again, i went in and had a look at the outfit, it was a slutty witch outfit with fishnet stockings, she had left them laying on her bed, so i made some minor alterations for her, ripping her fishnet stocking around the crotch and ass area as well as cutting little slits around where her nipples would be on the chest area. and as an extra, i shot sperm inside her bottle of juice she had already drank from, before i left.

Later that day she was back in her room, trying on the outfit again. Taking photos, noticing the slits where her tits were, her friends said she should rip them open a little more, she did what her friends said, she showed them her stockings that she didn't know how they got ripped, and her friends loved that idea, and also did that to their own.

Days later, the party was on, she showed up with her 4 other friends, taking odd their coats reveling their slutty outfits, obviously my sister was wearing the slut witch, one friend was a slut nurse, one was a slut doctor, one came dressed just as a slut in general, and the last friend the leader of the group was wearing a normal tight very short dress, it was red.

I had my own costume on, dressed as the scream character, but i had a painted mask on under the actual mask, i wasted no time hunting down my sister, finding her, and standing near her, watching the older guys giving them all drinks over and over, the girls were tipsy in less than an hour, as her friends were laughing and having fun, i sneaked over and took my sisters hand and pulled her across the room, she staggered as she followed very tipsy, dragging her upstairs to one of the bedrooms, as i dragged her into the bedroom, i pulled out my phone and began videoing, i pushed her onto the bed, as her legs went into the air, her shaved pussy was on display, i dove in face first, tongue slipping inside her virgin cunt, her legs over my shoulders, as i tongue fucked her virgin hole. Videoing close ups of my tongue in her pussy, sucking her clit, and lifting her dress up over her tits. In a hurry incase i was caught. I stood up and slipping my dick into my sister’s wet pussy. It slid in so easily because she was extremely wet. I slid fully inside, she was tight, but wet. I pulled her close her legs up, as i began fucking her fast, my balls slapping off her ass cheeks, as i fucked my own sisters virgin pussy, she was moaning, but also squirming, because i guess she didn't fully want it so fast, but i couldn't wait, i couldn't risk her realizing it was me or her friends walking in to see it was me either. I videoed her face, moaning, down to her small breasts, as i twisted her little nipples a and down to her pussy as my dick was sliding in and out of her, i fucked her fast and hard, for as long as i could before my time was coming to an end, she was that tight, i felt my balls churning the thick load, as it was filling my dick pipe, i couldn't hold back anymore, i let the first part of the load, the first squirt, shoot inside her wet pussy, before pulling out, as i struggled to make my way to her face, my sperm kept pumping a shot over her bald pussy, over her belly, i got to her mouth and pushed it inside pumping what was left inside her mouth, grabbing my dick, and squeezing every last drop out, into her mouth, as she swallowed it mixed with her own pussy juices, as i sat there videoing her face, the light shining in her eyes not able to see my face, i put a deep voice on and said, i will send to your shapchat group for your friends to see.

She was a little shocked to know this random was in her group. But before she could say anything i was gone, i put my dick away and vanished.

The next day i had cut the video up and added the edited parts to the snapchat group. So her friends could watch and enjoy, i sent the message saying i fucked her first. They all sent laughing emojis saying well done, who are you etc. I never answered, but i noticed her friends uploaded videos of that night also, it turns out her friends found her in the bedroom, after i left, she was sleeping, passed out, legs opened up pussy, belly and mouth still with cum on and inside, even her pussy was leaking some of my sperm. Her friends invited a couple of the older guys at the party, a couple of thirty year old men, in to join her fun, as the slut doctor sucked her clit and sucked the cum from her pussy, the group leader was licking the cum from her belly, the other two sluts were videoing while the two guys took turns fucking my sisters pussy, as well as the slut leader, the one who was sucking my sperm from her pussy was up kissing her face, and slipping her tongue in her mouth also, swirling my sisters pussy juice and my sperm inside her mouth, they were there for an hour, the guys fucked her deep had hard also, but came in her mouth and over the slut leaders ass, before leaving, the sluts took turns licking the sperm from their leaders ass and my sisters mouth, before dragging her semi unconscious body out, and back home, they left her in her bedroom while i was hiding in mine, waiting for her friends to leave.

I went into my sisters room she was thrown on the bed, legs open, pussy red from the fucking, and still wet and leaking a little cum and juices. I stood videoing her as i furiously rubbed my dick, seeing her laying there sleeping, naked open ass on display, i was able to cum fast, i moved close, and got between her ass cheeks and shot my sperm over her tight looking asshole, every drop over her asshole as it poured down between her open pussy lips onto her bed, i videoed around her face, to her ass again, close ups also, making sure not to get her room in the video, before going back to my room again. I didn't share the video yet, but it was a surprise for them later.
