After Party

Pairings: Kendall/Reader with side pairing of Kylie/Reader

Summary: Reader fucks Kylie and then she fucks Kendall...that's pretty much the plot! 3rd POV.

Content: strap-on sex, rough sex, some degradation, mentions of a threesome, plot what plot fic, dirty talk, consensual cheating (idk if that's even a thing lol but in this fic Y/n and reader have an agreement in place). There isn't any interaction between Kendall and Kylie in this fic.

Y/n was railing into her future sister-in-law’s pussy without a care in the world. Kylie was whimpering and moaning as she held onto the pillow on the bed. She hasn’t be fucked like this in what might be her entire life. A string of lazy lovers was all she was used to; ones who were only concerned with getting themselves off and not paying any attention to Kylie’s needs. Y/n was not like those men. She wanted Kylie to feel good while also fucking the absolute shit out of her.

Kendall was off somewhere probably being ravished by Bella and Hailey. Getting engaged seemed to turn the two into sex demons. They weren’t just always going at it with each other, but with others that they trusted. It was a given that Kendall was going to want to fuck Hailey and Bella again. She had hooked-up with them long before she even knew Y/n. The two have some sort of agreement where they have an unlimited hall pass. Y/n joked and said that they were giving each other one last chance to be sluts before they get married. Once they’re married they’ll only do stuff together, so now they are giving each other the chance to have one last hurrah without the other being present.

“I can fuck anyone?”

“Anyone. As long as I can too.”

“Okay, but who is off limits?”

“No one…besides exes, but I’m not flying to Colorado just to fuck some girl you used to date. And you definitely wouldn’t fuck my ex.”

“So if I wanted to fuck your sister, you wouldn’t mind?”

Kendall was taken back by Y/n’s boldness. She hadn’t specified which sister so Y/n had her pick of four different women. But, somehow she just knew that Y/n was going to pick Kylie. They were close with each other now that Kendall is able to curb her jealous tendencies much more than before. She can’t help but feel a little jealous that Y/n wants to fuck her sister, but she also has a list of people she wants to fuck, even women that Y/n has fucked before. That’s not quite on the same level as fucking her sister, but Kendall gave her to go ‘head.

That’s how she ended up in the spare bedroom with her strap buried deep in Kylie’s pussy while Kendall was in their bedroom with her two closest friends. There was a party going on downstairs, in fact it was their engagement party. They’ve had one so far, a vanilla one for friends and family. They’re flying to Colorado in two weeks to have a party in Y/n’s hometown for her close friends who can’t come out to LA. The one going on downstairs is the one that’s certainly not for family. It feels like a typical LA house party for the rich and famous. Everyone was too concerned with getting drunk and/or high to wonder where Y/n and Kendall were.

It was so hot to be fucking Kylie while her fiancé was just a few rooms away. Kylie’s thick ass slaps against her thighs which such a force that it makes Y/n delirious. Her fingers are digging harshly into her thighs as she fucks her over and over again.

“Such a slut,” Y/n grabs a fistful of her dark hair and pulls her head back while snapping her hips to her ass. “Getting off from your future sister-in-law fucking you like a whore.” Her cock was so deep in Kylie’s wet cunt that she couldn’t even open her mouth to speak.

The head of the cock pokes at cervix and makes her legs shake. She has no clue about Y/n and Kendall’s pact, but Kylie doesn’t feel an inch of guilt. She’s a selfish person and the only thing she wants is to keep feeling that cock pounding in and out of her. Her tits finally spill out of her dress as the bounce from Y/n’s sharp thrust. Y/n reaches her hand around to grab and grope one of her tits. Her nipples are incredibly hard and she moans louder as Y/n squeezes her nipples.

“Are you going to cum for me slut?” Y/n asks harshly. Kylie gives her no answer which only makes Y/n fuck her harder. Kylie’s loud crying was no over taking the music from downstairs that penetrated the room. She was loud like a porn star just as much as she looked like one. She came here dressed like she was looking to get fucked by someone, and Y/n is so glad that she’s the one who’s doing it.

Y/n slaps her ass which makes her yelp even louder. She somehow musters up the energy to throw her ass back against Y/n’s cock. Kylie doesn’t have to open her mouth to give Y/n the answer she was looking for. Her juices cover the cock fucking into her. The cock spearing into her makes her pussy squelch loudly which mixes with the sound of her cries of pleasure, her skin slapping against Y/n’s skin, and her tits slapping together. She felt so dirty that it was euphoric.

Kylie yelps when Y/n pushes her down against the bed and starts driving the cock into her pussy. Her moans turn to grunts as she begins to reach her high. Her pussy feels thoroughly used and she has yet to cum.

“C’mon slut…cum for me,” Y/n whispers in her ear. Her voice is dark and devilish which pushes Kylie over the edge. She doesn’t know what has gotten into her future sister-in-law tonight, but she’s going to leave their house feeling satisfied and smug.

She promises to keep this to herself as she cums all over Y/n’s cock. Her hair and make-up are probably completely fucked up, but it’s nothing a little trip to the bathroom can fix. She wants to see her tear-stained face in the memory and revel in the fact that Y/n did this to her. She never thought this would happen (and deep down she wishes it could happen again), but she’s glad it happened.

-

Kendall was roaming the hall with sore legs and cum drying on her upper thigh. She was looking for Y/n and was expecting to hear moans coming from one of the rooms, but all she can hear is the faint music from downstairs.

She enters the bedroom she shares with her future fiancé and sees Y/n sitting on the bed, strapon still attached to her.

“Hey.”

“Hey.”

Kendall walks over to the bed and jumps on it. Both of them have long forgotten about the party the rages below them.

“Did you have fun?” Y/n asks with a smirk on her face and a glint in her eye.

“It was amazing,” Kendall fawned. Her mind went back to being in that room with Hailey on top of her and Bella between her legs. Kendall wishes that Y/n could’ve been there, but she probably had so much fun with her little sister. “How was your time with Kylie?”

“You’re sister is such a needy pillow princess. I enjoyed fucking her, but I couldn’t stop thinking about how you two so different in bed. She also came a lot,” Y/n gestures to the strapon still on her that has Kylie’s drying cum on it.

Kendall eyes it and finds herself feeling a little bit odd. Maybe it’s the alcohol, or maybe it’s the lust, but she is falling into a haze again.

“She did cum so much,” Kendall whispers as she grabs the base of the cock. Y/n watches her closely and holds her breath while waiting to see what Kendall does next. Kendall does the one thing Y/n doesn’t expect her to; she lays on her stomach and takes the cock in her mouth.

“Baby?” Y/n gasps in disbelief. The cock is covered in Kylie’s juices yet Kendall sucks it off like it’s not from her little sister.

She hums around the cock and pushes all the way day until she’s deepthroating it. She doesn’t let up until her body is asking for more air. She pops it out of her mouth with a satisfied smile on her face.

“She tastes so good…so sweet.”

Y/n fights through her shock and watches her girlfriend take the cock in her mouth again. She was enjoying the sight of her girlfriend sucking on her cock. Y/n even thrusts her hips upwards a little bit so she can lightly fuck Kendall’s face.

“Your sister tastes good, doesn’t she? Her pussy was so fresh and wet too — I guess being a slut runs in the family.”

Kendall pops the cock out of her mouth again so she can speak.

“Did you like fucking her? Was her pussy tight?”

“My cock slid right into her wet pussy. She was moaning so loudly I’m surprised you didn’t hear it from all the way down the hall. She was so clingy too. But, it was so fun to get into that pussy and fuck her until she was begging and crying.” Kendall moans at Y/n’s words. “Does it turn you on to hear me talking about fucking your sister’s cute pussy? Of course your pussy will always be my favorite, but it was so, so fun fucking her twat.”

"Yea? Do you want to fuck your favorite pussy in the world right now?”

Y/n cocked her brow at her future wife.

“Hailey and Bella didn’t tire you out?” She laughs at Kendall’s insatiableness. “Sure they fucked you good, right?”

“Oh, it was amazing. But, nothing quite like you fucking me,” she bats her lashes as if Y/n was going to resist and say no to her.

“Come sit on my cock then.”

Y/n lays back on the bed and watches her eager girlfriend straddling her cock. Kendall sighs as she sinks down on it with ease. It’s still wet and sticky from the mix of Kylie’s cum and her saliva.

“This big cock was in your sister’s cunt just 30 minutes ago. I bet that makes a slut like you wet.” Y/n couldn’t believe she got to fuck two slutty sisters in one night, and one of those sluts is one she’s going to marry. She feels so lucky. She grabs ahold of Kendall’s hips and begins to fuck up into her.

Kendall’s tits bounce up and down through the thin, cotton tank-top she put on. She had lost her clothes in the spare room. The girls must’ve thrown them somewhere and she just couldn’t be bothered to find them. It didn’t matter anyway because she knew she was going to come right to this room and get fucked by her fiance.

“It feels so fucking good Y/n,” she coos as she throws her head back. The cock’s head pokes at every single sweet spot inside of her and that honeyed pleasure that lingered from earlier makes her feel amazing. She felt so dirty, so wrong that sitting on the cock that fucked her sister earlier is what makes her hornier.

“I bet it does. You’re my nasty little whore, you know that Kendall? My bitch.”

Kendall is too busy moaning to answer, but her moans are the affirmative words Y/n needs. Her sensitive pussy is already yearning for it’s orgasm. She feels the bubbles in her lower stomach becoming more intense. Everything feels so perfect right now. She’s with the love her life but is getting fucked like a cheap slut. The sweet balance they have is everything she needs in her life.

“Are you going to cum for me already?” Kendall nods her head which makes Y/n laugh at her, “of course you are. Go ahead and cum for me baby.”

Kendall begins to ride the cock hard and fast. Y/n is able to just lay back and watch as Kendall bounces herself eagerly on the thick toy. It’s such a sight to see; her nipples poking through her thin top and titties bouncing harder now as she rides the cock with all the energy she has left. Y/n grabs Kendall’s face and smashes her lips to hers. The intense pleasure Kendall is feeling causes her to deepen the kiss. On her tongue is the taste of Kylie’s cum that lingered on the strapon. Y/n has already gotten a taste of that pretty pussy before she fucked it, she just had to get her mouth and fingers in that hot cunt, but she tastes even sweet on Kendall’s lips.

Kendall pulls away to gasp as her high takes over her body. It feels like fireworks going off in her body and she’s on cloud nine.

“Good girl…my pretty slut,” Y/n coos as she recognizes all the signs of Kendall’s orgasm. She holds onto her hard and tight, not wanting to let go.

Even as Kendall slows down her movements, Y/n doesn’t let go and Kendall doesn’t want the cock outside of her. Everyone downstairs can see themselves out or pass out on their couch for all that she cares. Neither Y/n or Kendall are going to move once they lay down together. Everything feels so serene even after a night of debauchery. They hope the days of the rest of their lives are as sweet and indulgent as this one.
