Author Notes: This chapter from my personal opinion seems to be the best erotic fiction I have writen so far and I hope to make the next chapter even better!. I wanted to add a few more things into the chapter but after reading it over I couldn't find the right place to do so, so the parts I wanted added this chapter will show up in chapter 2. If you guys feel like something could be improved upon for the second chapter than don't be afraid to leave a comment.

Edit 1:There were a few edits with the story that I felt I should fix. Since I was tired there were a few typos and also mess up''s with the POV. If you see anymore errors leave a review pointing these out and thanks for reading :)

Kyousuke's day was going on as normal until something unexpected happened. Their was a knock on his door and the person there was someone unexpected. Kirino was standing with only a shirt and panties on.
"Let me have sex with you"
Kirino said while pointing at Kyousuke. Looking at her like she was an idiot he slammed his door closed, locked it and sat back onto his bed. Opening his book he ignored Kirino who was banging on his door.
"Geez, what a stupid question. Maybe she is playing to much Eroge again..."
He could hear footsteps moving from his door back to hers. I guess she finally gave up and returned to her room. Kyousuke's thought however was wrong when he heard banging from the wall behind him and could feel the impact on this side.
"Is she ever going to give up?"
Kyousuke tried to ignore this but was unable to because the sound was much closer to him. He sighed and placed his book closed on the desk beside his bed. Grabbing his sweater he decided to go for a walk to get away from Kirino.
When he unlocked his door and opened it Kirino must have known because the sound from the wall stopped and her door started to open.
"This is going to cause me many problems isn't it?"
Sighing he made his way towards the stairs but Kirino got into his way and puffed her cheeks.
"Don't ignore me!!!"
She started to hit Kyousuke with her fists.
"Hey cut it out, that hurts"
"Then have sex with me!! Idiot Brother"
Kyousuke closed his eyes and crossed his arms.
"No we can't do that because we are siblings"
"I don't care about that. They do it in Eroge all the time!"
"Yes, but that is a video game this is reality"
Kirino quieted down and looked up at Kyousuke with puppy eyes.
"Do you not wanna do it with me?"
Kyousuke looked down into her eyes but he couldn't beat her. He loved his cute little sister to much to refuse something she wanted to do so much. He was conflicted inside because he didn't want to perform a taboo act but he couldn't defeat that look.
"Fine"
Kyousuke sighed.
"Yay!!"
Kyousuke sighed again.
"Let's do it in my room"
"Alright, alright"
They both walked into her room and Kyousuke sat down on her bed. Kirino sat down on his legs facing him and moved her head towards Kyousuke slowly until their lips connected. Her lips felt soft on his own lips and the scent of Shampoo reached Kyousuke's nose.
Kirino moved her legs to wrap around Kyousuke's body and she moved her body up against Kyousuke's. He could feel her soft, small, still devloping breasts up against his chest. The kiss was slowly growing intense as their lust increased for each other.
Kyousuke reached up the back of her skirt and reached for her bra strap. After struggling he managed to unstrap her bra and pulled it out from under her shirt. She was wearing a pink bra that he had seen before. He could have guessed what she was wearing because of her panties.
Kyousuke threw it onto the ground and reached up the front of her shirt. Grabbing her breast he started to grope it softly. Kirino's face became slightly flushed and her breathing became slightly rougher at the new sensation in her chest.
Kirino started to move her body against his now half hard penis. He was still nervous of what was happening so he was not yet fully hard. Kirino stopped their deep kiss and looked deeply inside Kyousuke's eyes.
She slid down off his legs and went in between his legs. She unbuttoned his pants and pulled them down around his ankles. His penis was still laying asleep on his sack.

"You aren't hard yet? Let's fix that"
Kirino took her shirt off exposing her breasts. Her areola was slightly bigger than someone else of her age and her nipples stood up hard. Kyousuke's penis slowly got harder until it was fully standing up.
"So you like your cute little sisters breasts? Your such a pervert!"
Kyousuke looked away from Kirino's face and started to scratch his cheek in embarrasment. Kirino grabbed hold of his now hard penis and started to stroke it slightly as she watched it throb slightly.
"Wow it's starting to throb!"
Kirino was voicing her opinions to no one in particular as she played with his penis. This may be do to the fact that Kirino was extremely turned on right now. From this postion Kyousuke could see a slight stain in Kirino's panties.
"It's so hot"
Kirino stroked his penis slowly at first but as she got used to it she sped up her hand movements. Her hands were clumsy on his penis but his lower body felt amazing with each stroke. His impending climax was starting to rise inside him, he didn't expect Kirino to make him feel so good.
"Kirino, i'm cumming"
He wanted to enjoy the pleasure much longer but he couldn't hold on any longer. One large shot of semen shot several feet into the air and landed on Kirino's face. Kirino let go of his penis because of shock and his next load shot out and landed on her breasts, completely covering them.
"There is so much semen!"
She scooped up some semen with her index finger and looked at it interestingly. She has seen it in her dirty games but this is her first time seeing it in real life. She licked the semen off her finger and swirled it around in her mouth before swallowing it.
"It tastes kind of salty but I might actually enjoy it"
Kyousuke's penis was starting to lose it's hardness but the sight of Kirino covered in cum made him get instantly hard again.
"You look ready for another round"
Kirino laid down on the bed with her bottom half hanging over the edge. The cum on her breasts soaked into the sheets on her bed leaving a white stain on it. Kirino was too deep in pleasure to care about that small issue.
"Come on Kyousuke"
Kirino's voice was suductive and got Kyousuke on his feet instantly. He rubbed his hands across the soft flesh of her butt cheeks enjoying it highly. His penis throbbed in happiness as his hands rubbed across.
Kyousuke placed his penis up against her pussy and was ready to push in when Kirino stopped him.
"Hey don't use that hole"
She lowered her hips down so his penis was touching the entrance to her asshole.
"We don't have any condom's so if you cum inside me I might get pregnant but if you cum in her we should be safe"
Kirino made a good point and Kyousuke didn't bother to aruge with her. He slowly pushed his penis inside and could only get a third of his penis in before it was too tight to move anymore.
"Hyuahhh! Your penis... your penis is... inside my asshole!"
Kyousuke moved his hips almost pulling his whole penis out and pushing back inside.
"Hooh!! Haayah!"
Kirino almost screamed in pleasure each time he moved inside her asshole. Her asshole was squeezing tightly on his penis trying to drain him completely of his seed. Kyousuke couldn't even get half his penis inside her asshole before it was to tight to move.
As he moved inside her and Kirino screamed in satsifaction Kyousuke was unable to hold back his intended climax. His seed was released inside Kirino's asshole as she screamed. Luckily their parents weren't home at the moment so her scream was only heard by him.
He finished unloading my seed inside her asshole and without taking a break started to moved my hips again.
"Hyahhh!!! Wait... you just... Hooooh... finishing... coming"
Kirino could only manage one word at a time as he shoved half my penis inside her asshole. The semen that I released inside was now working as lube for my entrance. Might as well tease her with some words.
"So Kirino is just a masochist who enjoys her brothers cock in her asshole huh?"
"Haaaaahhh... no that's not... true!"
Kirino could barely manage those words out proving my point.
"Inside her seems to think otherwise"
To emphaise his point, Kyousuke made one large thrust and his whole cock slid inside her tight asshole.
"Haaaaah!!! It's all inside!!!!!"
Kirino asshole clenched tightly on Kyousuke's penis casuing him to shoot his third load of the day. After he finished his penis didn't calm down and was still raging hard inside her asshole.
"We aren't done yet!"
Kyousuke pulled back and thrusted deep inside her asshole once again as he spoke. As he thrusted he noticed that the scent of the room had changed. Her room used to smell like what you would expect out of a females room but now it smelled like sweat, cum and sex. The smell was enough to make someone's nose curl up but Kyousuke didn't mind the scent, it was actually turning him on even more than he already was.
Each time Kyousuke thrusted it made the semen from inside her asshole drip outside and slide down her pussy and onto the floor. Kyousuke wanted to make Kirino feel even better! Using his free hands he used one to play with her clitoris and his other to rub her nipple.
"Your pounding my asshole and stimulating my clit and breasts! I'm cumming!!!"
Kyousuke could feel her asshole tighten up tenfold as she screamed in pleasure. Her body convulsed as she came. I managed to hold back from cumming under such intense presure and pleasure. When he asshole loosened up and she finished cumming I continued my movements.
"Hoooooooooohh!!!! Haaaaaaah!!! Wait.. I just finished... cumming!!!"
Ignoring what Kirino said Kyousuke continued to pound the inside of her asshole.
"If you keep this up I am going to cum again"
Kyousuke was growing near his fourth climax of this scene so he was finally ready to end with both of them coming.
"Kirino... i'm going to cum!"
"Same here! I'm going to cum!! cum!! cum!!"
As Kyousuke let his load out inside Kirino's asshole for the third time she came once again and tightly gripped his penis. After he was finished and he pulled out of Kirino's asshole he felt too drowsy to walk and laid down in Kirino's bed.
She stayed in the same postion for a while as cum dripped out of her asshole and onto the floor creating a puddle. When she tried to stand up she felt extremely dizzy and laid down in the bed along side Kyousuke and passed out with Kyousuke following close behind.
