Backdoor (ChipFic)

>Lupa sat on her bed with her diary open
>She had various strategies and sketches about seducing her brother
>Plans that had served her well, things were progressing smoothly
>Her mother says she got that from her father
>Lupa chewed on her pen as she sat with her arms crossed
>She stared down at the last bullet point of a list
>Sex
>She tilted her head side to side as she ran ideas through her head
>"How to go about this..." she said out loud to herself
>There were roadblocks in the way of course
>It was going to hurt, and Lupa was a bit of a wimp deep down
>There was also contraceptives, Lupa did not want to deal with that yet
>She could ask her mom, it was her idea to just kiss Lemy that started phase 2
>Her mother had a knowing smile the next day when Lupa was grinning in the morning
>Lupa frowned, that had been an embarrassing experience, and she didn't want to repeat it tenfold
>Ask dad?  "Hey daddy, I want to carry on the family tradition and fuck my brother, can you pick me up some rubbers?"
>The girl flopped back on her bed
>I mean, dad wouldn't say no, he would help out anyway her could
>That too, would be too embarrassing
>Anal?
>Lupa turned over, burying her head in her pillow, kicking her feet against her bed
>She remembered just last week when her brother used his mouth to give her the strongest orgasm she'd ever had
>He poked at it when he was eating her out, looking up asking for permission
>She expected him to prod it with his finger some more when she nodded, not thrust his tongue in
>She'd actually screamed
>She looked at nothing in particular and nodded to herself
>"Alright, we're going to need some lube"

>A few days later the weekend rolled around
>Lupa had spend the last few days doing research
>She knew they would have to take it slow
>And she should expect to walk funny afterwards
>She took the shower head and cleaned herself as thoroughly as possible
>She had made sure to fast before hand as well
>Lupa was the girl with the plan
>Drying herself off stood in front of the mirror, staring at herself
>"You got this, phase 3"
>She got dressed, one of her skirts that ended above the knee
>A simple t-shirt with some old rock band on the front
>Lemy's, it was the same one she stole from his room weeks ago
>Washed now, of course, she wasn't THAT perverted
>Long Socks that went up to her knees
>And nothing else
>She walked over to the tub and grabbed a bottle of baby oil she had in there with her when she showered
>The tutorials she read said it would be a good idea to warm the lube of choice
>Grabbing a towel she shoved it in a bag along with the oil and her phone
>She made her way to Lemy's room

>Lemy sat at his desk, brow furrowed
>Holding a screwdriver in his mouth he hands worked quickly as he dismantled a laptop
>One of his sisters had dropped it, now something was rattling inside and it would crash on start up
>Lifting the cover he quickly spied the problem when the sound of his door opening, and locking, demanded his attention
>Turning around the screwdriver fell to the floor as his jaw dropped
>Standing there was Lupa looking amazing
>A shorter skirt, no sweater, a t-shirt that looked a size too small on her
>"Wait is that my shirt?"
>His thoughts were interrupted as she made her way forward, setting a bag down on his dresser and reaching in to bring out her phone

>Music he had never heard before filled his room
>Lemy had no time to think as his eyes bugged out
>His sister was swaying her hips to the beat
>Lupa flashed him a wicked grin and bedroom eyes
>Lemy gulped and winced as he started to strain against his shorts
>The girl widened her stance as she moved in time to the music
>Her brothers eyes widened as he caught a glimpse of her bare ass
>She was naked under the skirt
>She gave him a dangerous smile as she teased him, giving him brief flashes
>Suddenly she grabbed the bottom of her (his?) shirt with one hand and pulled it over her head in one fluid motion
>She had practiced that

>Lemy was drooling slightly now
>Lupa ran her hands over her taut stomach and up to her rock hard nipples
>She was drooling herself now, though her mouth was dry
>Lupa was as worked up as she was going to get without setting herself off
>She walked towards Lemy with deliberate steps
>Grabbing his still dropped jaw she kissed him deep
>Breaking off, they were both panting
>She stared into his eyes with knowing grin
>Lupa grabbed her brothers hands and brought them to her hips
>She spun around, her back to him now and used his hands to hike up her skirt
>The dour girl heard her brother gulp loudly and smiled
>She swayed her hips and dropped them slowly, sitting on his lap
>Feeling hardness between her butt, she slid her hips back and forth
>Lemy cried out and leaned forward, wrapping his arms around her waist in a futile attempt to stop her
>Feeling encouraged by his response Lupa sped up, palming her hands over her brothers and gliding them up and down her torso
>He was nuzzled in her neck now, she felt his breath hot on her nape
>She wanted him to bite her there, but that was for another time
>Rocking her hips faster now she felt him tense up and he hugged her tight
>She clenched him between her and sent him off the edge with a yell

>Lupa leaned back into her brother, they were both drenched in sweat and gasping for air
>He was still shuddering and she gave little wiggles with her hips to coax the last of his seed
>"How was that?"
>"That....that.." he didn't have enough air in him to form a sentence
>"That good huh?" she grinned "Listen....I want to try something"
>She felt his breathing stop and he tensed up
>He knew what it meant when she said that
>They had done pretty much everything
>Everything except...
>Lupa turned to face her brother "You up for it?"
>Lemy gave a shaky nod
>The snow haired girl got up and walked over to the bag she brought with her
>She reached in and grabbed something, walking back over and setting it in his lap
>He looked down at the item in question, expecting a box of condoms he instead saw a bottle of baby oil
>His eyes shot up at his sister, hands on his bed now with her hips in the air
>Her yellow eyes met his blue and understanding dawned on him
>Abruptly standing up and fumbling with the bottle he took unsteady steps
>She was on her hands and knees now and looked back with a grin but with uncertainty in her eyes
>"U-use lots ok?"

>Lemy noticed that she was trembling
>He wasn't the only one dying of nerves here
>She was trusting him with this however, he had to step up
>He planted a kiss on her lower back that elicited a whine from his sister
>Pouring a generous amount of oil on his hands, he started massaging her rear
>She was no longer on her hands, face buried in his pillow
>Lemy prodded at her with his finger making her yelp, and went back to rubbing her
>Slowly, with the pad of his finger he pushed into her
>A tasked made much easier thanks to the liquid assistance
>As he slide knuckle deep the ashen girl let out a low moan
>Very slowly he worked his way out, and than pushed back in
>"Stop..." She was gasping for air now "Stop teasing me"
>There was a need in her voice that fired Lemy up
>Slipping off his shorts and wiping himself off Lemy coated himself in the oil
>With one hand on himself and the other on his sister's butt he swallowed
>"Are you ready?"
>Still face down in his pillow she nodded
>Bringing himself to her exit he tensed
>Pushing in painfully slow, Lupa postured up again, arching her back
>"Ohhh goddd"
>Halfway in Lemy stopped when he saw her wince
>With no bandana to hold it back, sweat poured from his face
>Lupa's breath left her as he suddenly pulled back just as slowly as he went in
>As her brother inched he was back in she felt her knees buckle and she suddenly fell prone on the bed
>"Lu!" rushing over to her Lemy had a look of fear and concern on his face
>Fear that became confusion as he laid eyes on the goofy face his sister was making
>"Don't you dare stop"

>She didn't have to tell him twice
>Guiding himself back into her, Lemy pushed his hips forward, using his fist between them as a measure of where to stop
>"D-deeper" she moaned "you can be rougher"
>Lemy reached for her hand and held it, she squeezed back reassuringly
>The young man thrust forward at a snails pace, until finally he could go no further
>The girl was moaning loudly now
>He brought his hips back and bucked forward once more, faster this time
>Lupa felt the air escape her and her vision blur
>she squeezed his hand, giving him the go ahead
>Soon Lemy found his rhythm, as wet slapping filled the room drowning out the music
>Lupa was biting down on the pillow, eyes rolled back
>She was lost in the feeling, not aware that she grunted with every thrust
>'Oh fuck..Lupa" her brother was speeding up now
>He leaned onto her, again in the crook of her neck
>His end was approaching fast, try as he might he couldn't slow it down
>She felt teeth on her neck as he surged forward one last time
>Her eyes shot open and she screamed as her toes curled so hard they cracked
>She was trembling as she felt him expand inside her
>He had tackled her off the edge
>Lemy collapsed on top of her, too exhausted to hold himself up any longer
>They both struggled to breathe, feeling like they ran a marathon with how soaked in sweat they were
>They stayed like that for minutes, no words, just gasps for air
>Finally Lemy slid off her back and to her side
>"Are you ok?" he asked with concern written all over his face
>Lupa opened her eyes lazily and had a goofy grin
>"I'm staying here tonight, I don't think I can walk anymore"
