"Hey Nii-chan!"
Sitting on his bed Kyousuke was reading a book when his sister entered his room without knocking. He looked up from his book to see Kirino standing in the doorway to his room.
"How many times have I told you to knock?"
"Sorry Nii-chan, could you do me a favor?"
"Sure, What is it?"
"Could you come to my room?"
"Why? We just finished"
"Yeah I know but I have a present for you!"
A Present? Kyousuke was confused at what she meant. Standing up from his bed he closed his book and placed it on the desk beside his bed. Walking down the hall he stopped before Kirino's door and opened it. Upon walking inside he saw something that was unexpected.
Laying down on Kirino's bed was Ayase. Her hands bound by ropes and her mouth gagged to keep her from yelling she looked angrily at him. Kyousuke was surprised to see Kirino's best friend lying on the bed.
"Why is Ayase tied up?"
"This is my present to you"
"Who gives someone another human as a present?"
"Come on, you know she likes you! Why not have a little fun"
Kirino walked over to the bed and got on top of it. She crawled behind Ayase and lifted her up onto her knees. Grabbing the bottom of her shirt she lifted it up exposing her underwear. She was wearing a black bra which surprised Kyousuke a little. Even though she always acted crazy he never thought she would wear such adult underwear.
Kirino unstrapped the bra from behind and let it fall onto the floor. Before Kirino and I started having sex Ayase's breasts would have been larger than hers but now it's a different story. Kyousuke would always play with her breasts when she watched tv and even a few times when Kirino was on the phone with Ayase. Ayase must now understand why she was moaning on the phone every time they talked recently. Kyousuke knelt down onto the edge of the bed and placed his hands on Ayase's breasts.
"Kirino's are bigger but these aren't half bad"
He rubbed her breasts in circles as he squeezed slightly hard. Her nipples were starting to get hard at the new feeling in her bosom. Kirino slid her hand down on the front of Ayase's panties and started to rub her pussy. She tried to hold back but Kyousuke knew she was feeling this. Her breathing was starting to get heavier and her face was slightly flushed red.
"You try to hold back but I know that we are making you feel good"
"Ayase, your pussy is stating to get wetter"
Kirino and Kyousuke started to tease Ayase who was shocked at how dirty she was being. Her pussy getting wet from being raped by her best friend and her brother, how can this be?
"I can't hold this any longer"
Kyousuke pulled his pants down quickly which made his cock bounce back up. It was standing up fully hard and Kirino thought it was harder than usual. Having a threesome must have turned him on more than normal sex. A smile appeared on her face as she thought that.
"Time to use these!"
Kyousuke put his penis in between her breasts and pushed them together taking his penis in. The soft flesh against his penis made him feel good.
"Your breasts are so soft and feel good"
Kyousuke smiled happily as he continued to get a titty fuck. Looking at her mouth he could see saliva coming from her mouth and dripping onto the bed. Her eyes were half closed and her breathing was heavier than normal.
"So you're starting to feel good huh?"
"What, there is no way!" Ayase thought. Pre-cum started to come from the tip of his penis and onto her breasts. His pre-cum started to get onto her breasts making them slimy. The feeling was much better than before.
"Now let's use this"
He pulled the gag out of her mouth and quickly replaced his with his cock before she could scream.
"Your mouth feels amazing!"
Kyousuke moved his hips quickly like a piston from an engine. He would push his cock deep down her throat and pull back until his dick was almost out of her mouth and than he would repeat. The feeling of her throat made Kyousuke lose his self control and his hips sped up until he shot his load down her throat. His cock unleashed a load that was large enough to fill both Kirino and Ayase's mouth but it was only going into Ayase's mouth.
"Ahh, that was amazing!"
Kyousuke pulled his cock out as he gave his opinion.
"Ayase, you came from Nii-chan fucking your mouth-pussy didn't you?"
"N-No"
Ayase was barely able to speak because of how good she was feeling. I can't believe that she managed to get off by me fucking her throat. Kirino put her hands up Ayase's skirt and pulled of - her completely soaked - black panties.
"So you really did cum? Well that was just the beginning, we are going to make you feel much better!"
Kyousuke's cock was already standing tall again as he spoke those words. Ayase was unable to react as she laid down on the bed in Kirino's arms compeletely lost in lust. Lot's of juice was pouring out of her pussy and staining Kirino's bed. Kyousuke put his penis up her skirt touching her pussy.
"W-Wait, s-stop!"
"Your still not honest with how you feel? I guess I will have to drill this pleasure into your head!"
With one thrust Kyousuke broke past her hymen and entered deep inside her pussy. She attempted to let out a scream but Kirino silenced her by kissing her. The sound of muffled but was still loud enough for anyone outside the door to hear. Ayase's pussy pushed down tightly on Kyousuke's cock so he had troubles moving.
Making small thrusts he sparked response from Ayase and also slowly loosened up her pussy. His hip movements slowly grew larger until he was able to freely move inside her. Tears poured down her face and onto the bed because of what happened earlier. He did just break her hymen with one large thrust so pain was expected.
"Don't worry, Nii-chan will make you feel good"
As if to help Kyousuke out Kirino started to lick her hard nipples.
"Ayase, your breasts are so big!"
Kirino voiced her opinions to no one in particular as she sucked and played with her nipples. Ayase was starting to feel good from the stimulation to both her pussy and breasts at the same time. To make her feel even better Kirino reached down and started to rub her clit with two of her fingers.
"N-No not there!"
"So your clit is your most sensitive spot huh?"
Kirino's most sensitive spot was her nipples only because Kyousuke played with them almost all day. Kyousuke happen's to be a breast lover and played with her breasts with intent to make them bigger (and he succeeded)
"Do you always play with her clit while you masturbate?"
Ayase looked away from Kirino in embarrassment which made both Kyousuke and Kirino want to tease her more. Kyousuke lifted her butt up with one hand and put his finger inside her asshole.
"Hyahhhh! T-That's my asshole, your fingering my asshole!"
Ayase screamed out in ecstasy as every part of her body was being stimulated. Her pussy tightened down considerably on his penis making him get close to coming.
"Your penis is starting to heat up and grow bigger inside me"
Kyousuke was already ready to cum the tightness of her pussy was making him feel better than when he was inside Kirino's pussy.
"Your p... cock is throbbing inside me like crazy... are you going to cum?"
Ayase wasn't thinking clearly anymore as she spoke aloud.
"T-then, cum... just like this... cum inside me!"
Kyousuke couldn't hold it any longer and he shot his load deep inside Ayase's pussy. His penis was pressed up against the entrance to her womb as his load shot inside. Once he finally finished he pulled his cock out and sat down on the bed, looking down at Ayase who was now lost in ecstasy.
"Maybe we were a little rough on her for her first time?"
Kyousuke voiced his opinion and looked over at Kirino who didn't reply. She was near the end of the bed on her hands and knees, her ass pointed towards Kyousuke.
"Nii-chan, I have been waiting for so long. Can you please fuck my pussy with your rock hard cock?"
Kyousuke stood up and faced Kirino with his cock against the entrance of her pussy.
"If that's what you want then..."
He entered deep inside her pussy and yelled
"Then I will give it to you!"
Kirino screamed out in pleasure at the feeling of her brothers cock. She just finished having sex with Ayase so it felt larger than usual. The usually perfectly fitting cock was now larger than the mold he had made inside her.
"Your cock feels soo good!!!"
Kirino yelled as Kyousuke moved his hips inside her. The feeling of pleasure was many times greater than usual with his larger cock. His penis was so hot that it felt like it would burn her if it touched her skin. That mixed with how hot her body was made her feel like she was literally melting.
"Having sex right after finishing... I don't think I can hold on..."
Kyousuke was already ready to cum once again.
"It's okay, i'm about to cum as well so... Cum inside my pussy! Dirty it with your seed!"
"I-I'm cumming!!!!"
Kyousuke grunted as his load started to shoot from his cock. Kirino said that same thing but screamed it almost at the top of her lungs. After he finished cumming Kirino lost all the strength in her body and fell onto her stomach. Her face showed that she was completely in heaven. He smiled at the face which he thought was cute before he walked out of the room towards the bathroom.
