Yutaka had never had sex, she had never even masterbated. She was in fact, pure. In body, in spirit, and in mind. The same however could not be said for the rest of her family, they were all a bunch of perverts, of course, being so pure, she couldn't really see that part in them. But it was an undeniable truth.

Yutaka's cousin Konata Izumi was one such pervert. She had always wondered what exactly it was that made Yutaka different from the rest of them. One day her perverted otaku head spun a very likely theory. Yutaka had always been sheltered, from everything and starting at a very young age. Konata theorised that all Yutaka's inner pervert was hidden, walled up somewhere inside her, just building and building. So should she somehow reveal the dirty side of life to her sweet little cousin, her inner perv would unleash itself on the world, and it would be far more powerful than any other from being neglected and bottled up so long.

Thinking of how funny it would be to see Yutaka in such an out of character state, Konata decided to put into action a plan to show the salmon haired loli just how dirty the world could be. She tried leaving dirty doujinshi where Yutaka would find it, hoping she would flip through before returning it. That plan failed. She tried leaving her computer on with less than clean pictures appearing on the screen, then asking Yutaka to get something from her room. That plan failed. She tried getting her to play one or two of her favorite dating sims games. That plan failed. She was beginning to believe that maybe she was wrong, maybe Yutaka didn't have a single perverted bone in her body.

Konata was exhausted, she wasn't getting through to her little cousin at all. The girl needed some stress relief. Konata turned off her computer and sat on her bed pulling out her trusty yuri manga. She flipped through, reading thoroughly. She ran her tongue over her lips as the manga started getting steamy. She watched as the girls ran their hands all over each other, groping and rubbing against one another.

Konata was getting hotter the further she read, giving in to temptation, she lightly ran her hand over her shorts, lightly rubbing herself through her clothing. Getting herself hot and wet. A small moan escaped her lips as she pushed her hand into her shorts, now laying her dirty manga on the bed so she could concentrate on fucking herself. She stared down at it as she plunged her fingers inside herself.

Yutaka was walking back to her room from the bathroom when she heard a deep groan come from Konata's room. She stopped, assuming something was wrong, was she sick? Oh that would be bad. She peeked in, completely shocked by what she saw. Her cousin was masterbating, her eye's glued to a book on the bed. Yutaka assumed it to be a dirty manga. She wanted to leave, to flee, but she couldn't. All week she had been bombarded by dirty books and images, this was the last straw. Something inside her snapped and like a flash her hand was down her pants and she was rubbing her soft lips through her panties. The wet sticky fluids now covering her underwear were just making her hotter.

She didn't think twice before sneaking in the room. Konata was now laying on her back, her shorts hung around her ankle, left for lost as she fingered herself roughly. Yutaka couldn't think, she just wanted to fuck. Quickly she striped down, closing the door and walking over to the bed. It was then that Konata noticed her, she jumped, surprised.

"W-w-w-what are you doing here?" She asked as she covered her exposed crotch in shame. Yutaka didn't reply, instead she crawled on the bed and straddled her cousin. Who had now noticed her naked state. Being so horny already Konata didn't stand a chance, she was helpless as she stared longingly at Yutaka's body and grinded upwards into her.

To add emphasis on what she wanted Yutaka grinded her naked pussy against her older cousin's body. Konata moaned, staring down at her pussy, which was only covered by a small tuft of red hair. Konata was allot of things, but their was no way she was gonna end up on bottom. She sat up, kissing Yutaka's hot lips passionately as she pushed her down, staying wedged between her thin legs. Konata was no beginner, she had experience, and like any professional, she got right to work.

Konata was biting and suckling little Yutaka's neck, making the little girl moan out her name as she snaked her hand down her petite body. She plunged in her fingers, lightly thrusting her hips against her younger cousin. "Gah FUCK ME! FUCK ME!" She hissed as she gyrated into her older cousins intimate touch. Konata now realised this Yutaka was different, she wasn't sweet, she didn't need to be treated with tender care. She wanted to be fucked and fucked hard.

So she stopped and stood up, much to Yutaka's protests as she tugged Konata's shirt, trying to pull her back down. But to no avail. Konata walked to her dresser, immediately stripping off her shirt and bra before opening it up and digging around. On the bed Yutaka had taken her pleasure into her own hands, literally, she was groping her tiny breast with one hand and fingering herself harshly with the other, her love juices dripping onto Konata's sheets.

Finally Konata had found what she was looking for, she pulled out a dark purple double sidded dildoe. She walked over to Yutaka with it, whose eyes lit up at the sight of the rather large toy. Konata slowly inserted one end inside her wet pussy. "Now Yutaka if this is your first time you may want to be ca-" She was cut off by Yutaka taking the other end and slamming it inside of herself. A sharp moan escaped her lips as she humped the toy again and again. Konata was desperately trying to keep up, but it proved a losing battle as her cousin was lost in her lust, thrusting her hips at a surprising speed.

Konata could feel the toy sliding in and out of her at great speed. Moaning loudly she knew she was close. "Y-y-y-y-yutaka I'm go-gonna CUMMMMMM" She shouted as pleasure tore through her very being. She had never felt such an amazing release in all her life. And Yutaka was still fucking her, panting and groaning as she tried to speed up her own release. Finally it hit her as she threw her head back.

"FUUUUUUCK" She shouted as she experienced her very first orgasm. Hissing as she came down from her high and her hips slowed their pace to a stop. Both girls were left in a sweaty panting heap. Yutaka was the first to slide the toy out, her blood and juices covered it. It was her first time and all.

"I'm gonna go clean up okay Onee-Chan?" Yutaka smiled as she pulled her clothes back on, save for her underwear. Konata was dumbfounded as her mind was now clear. What had gotten into Yutaka. She had suspected there might be a bit of an explosion of perversion, but nothing like this. Yutaka acted like a completely different person, she had screwed her without mercy, and had acted almost like nothing had happened afterwards. Maybe this was a bad idea she thought before her tired body overtook the rest of her and she passed out.
