Lynn fat fic (lewd/short)

>Lynn chugged down another soda and let a loud burp out
>"BUUUURP! Hey Linc, can you give me a ride?"
>ever since she broke her leg in that lacrosse match she would often ask her brother to carry her upstairs
>in the beginning the boy wouldn't mind, but after a few weeks it became much harder to do it
>this time, Lincoln could barely lift her off the couch
>"ughh... hey sis, I don't mean to sound rude, but maybe you should take it easy with the sodas. And the subs, the sports drinks, the sweet potatoes..."
>"what are you talking about bro? I NEED my gainz!"
>Lynn was used to eat a high calorie diet, since she'd spend most of it doing sports
>but with a broken leg she spent most of her time lying in the couch, watching them on tv
>she thought she would at least keep herself updated on tactics and techniques since she couldn't train them, right?
>Lincoln insisted: "but you're not spending all that energy, and to be honest, it's starting to show..."
>Lynn took that as a shock
>yeah she was gaining a few pounds, but nothing she wouldn't burn easily with her usual routine
>besides, it wasn't that bad, was it?
>"wow, are you serious Linc? Is it that bad?"
>Lincoln wasn't able to answer right away since he was focusing in not breaking his own knees climbing up the staircase
>"hey answer me!" Lynn gave her brother a punch in the arm"
>he fell down with the weigh shift
>"see Lynn? You're fucking FAT!" Lincoln yelled, angry at his sister
>Lynn's eyes filled with tears
>"I-I'm sorry Linc! I never been this long without practicing, and ir's been really hard" she cried, trying to get up and go to her room
>as Lynn steooed with her right leg, she fell down once again, crying enven louder as she landed
>Lincoln felt horrible about snaping at his sister, even more so after realizing she was having such a hard time with her injury
>"there must be a way I can make her happy" the boy thought
>"hey sis, don't be like that...I'm sorry for what I said"
>"but you were right! I'm a fat slob! Just a waste of space"
>"noo, I didn't say that. You're going to get better soon and go back to old self. Besides..."
>Lynn stopped crying, dried her eyes with her arm and looked at Lincoln
>"besides what?"
>"I mean, it's not like you're suddenly ugly or anything... you still look great" Lincoln blushed a litte when saying those words
>Lynn's eyes widened
>"and actually, you're so much softer now that you have a few extra pounds. It feels kinda funny to pinch you now haha"
>Lincoln pinched Lynn's belly, which was too big for her jerseys now and let some skin showing
>the girl laughed and pinched Lincoln back
>"it's not fair! I can barely pinch you! hahaha"
>the two siblings started rolling down the stairs, pinching and ticking each other
>Lynn let out a small shriek of pain as she hit her broken leg while rolling
>Lincoln, worried as he always was, stopped playing
>"are you alright sis?"
>"it's okay, I just hit my leg, no biggies"
>Lincoln, still entangled in his sister, curved his body to give her a kiss on the leg
>without thinking, as he straightened himself up, he gave another small kiss on her tight
>and another, and another, slowly making his way up
>Lynn blushed and she asked what he was doing
>"I just want to make you feel good, sis..."
>Lincoln repositioned himself and took her shorts of, being careful not to hurt her leg while he did so
>Lynn's legs were sweaty, even more than when she did sports
>maybe due the tickling, maybe due all the extra fat she was carrying, or maybe even anticipating what her brother was doing
>he got on his knees a couple of stairs below Lynn and carefully spread her legs open
>he grabbed her now soft thights, delighted how good they felt
>he couldn't help but to give her a bite
>"aw dude, that hurt! Stop it!" Lynn's voice betrayed her, and Lincoln continued to make his way to his sister's panties
>the smell was inebrating
>Lynn's sweat was something Lincoln was already used to, but now that she gained some pounds it seemed...different
>her soft thighs felt incredible, and the boy felt compelled to lick every inch of them
>he made his way up to her crotch, and each moan Lynn let out turned him on even more
>Lincoln pulled the panties aside and took a moment to see his sister's pussy close, marvelled at the perfection
>he tried to adjust himself to get a better position to stuff his face in, but ended up shifting Lynn's position as well
>both siblings slid down a couple of stairs, Lincoln landing on his back
>Lynn also went all the way down, with her legs still open wide
>she hit the boy right in the face with her groin, smothering him
>the girl tried to get up to prevent him from suffocating, but Lincoln grabbed both her legs and didn't let her do it
>Lynn could feel his erection on her back, and surrendered to her brother's will as soon as he started licking and munching on her pussy
>every few seconds he would take in a big breath before returning to pleasuring his sister orally
>the tomboy felt a rush different from any sports she ever tried
>a tingling, warm sensation rose from her nether regions all the way up her spine
>she could no longer think about her broken leg, her weight gain or anything else
>all she was able to do was enjoy her brother's tongue, his hands grabbing her tights firmly, his throbbing erection moving around her back
>the boy was edging from rubbing his cock on Lynn's back foldings, enjoying her texture
>Lynn let herself go in a big orgasm as Lincoln continued to pleasure her
>he was going crazy with her pussy taste and smell, and her twitching while she orgasmed was all the boy need to climax as well
>the cum covered a good part of Lynn's back and slowly came down, making curves accompanying her fat handles
>Lincoln felt blissed as he could help her sister feel good about herself
>they both lied down, Lynn still a couple of stairs above Lincoln
>she was getting goosebumps from the running cum in her back
>even more so after Lincoln started sucking on her feet, grabbing the thick leg that didn't have a cast on
>his tongue was licking off the sweat between her toes while his hands massaged her ankles and calf
>"are you ready for round two, sis?"
>"that sounds good Linc, but first..."
>Lincoln anticipated her answer
>"can I have a snack?"
