"You… Want this?" She asked in shock. Ayami couldn't believe what her ears were hearing. This had to be some type of dream, or maybe a sick joke Arata was pulling on her. "It's okay, that kiss meant nothing. You don't need to make me feel better about myself." The girl tried to play it off. It seemed better to try and move on as quickly as possible.
"I mean, I didn't hate it." He admitted to her, which caused a bit of an awkward silence. It was the truth, and while Arata couldn't say that he was feeling something with his own sister. There was certainly something between them. The boy got really bashful when he said that to her. His body felt strange to be in this situation. "So maybe, we could do it again?"
"Arata, I…" His big sister had no clue on how to react to his request. Her brain was doing everything in its power to force her to say no. Reject him so that they could put this incident behind them. Yet her heart was on the polar opposite side of the argument. It controlled her body, as she leaned in towards him. "This feels wrong, but…" She quietly whispered as their faces were mere centimeter apart.
"But I feel like it's right." He finished her sentence, as once again their lips met. The two held a deep and passionate kiss. One that gave them both a feeling they had never felt when kissing someone else. Gently, they separated from one another, both of them red hot from the action they just performed.
What were they thinking? They both were silently asking themselves that question. It's one thing to discover romance with someone you've known for such a long time. But it wasn't that they were childhood friends. No, they were relatives. Brother and sister at that. Their hearts were beating ferociously at the revelation, but nothing seemed to be able to stop their wills.
"You can… Touch me here." She quietly broke their silence, taking a hold of his hand. Slowly, Ayami guided Arata hand up to her chest, him doing nothing to stop her. The boy felt his palm cupping her breast, which wasn't as large as the average girls, but fit her slender body.
Ayami grimaced a bit when he took a hold of her like that. This was the first time the girl ever had a boy touch her like this, and it was already getting her wet down there. A wave of heat traveled up her body as she realized who it was that was making her feel this way. There was no way either of them could get used to the idea that someone related to them by blood could turn them on.
And turned on they both were, with Arata himself now feeling his pants get a bit tighter. The boy was sporting a hard on, which really wasn't uncommon these days ever since he made friends with Yogi and the gang. There were just so many cute girls surrounding him everyday. But right now, there was one special girl sitting next to him.
Carefully, Ayami began to undo her blouse, revealing the lavender bra she wore. Arata's eyes widened to the sight. While he can't say he ever saw his sister in the nude before. In fact, when they were much younger, the two bathed together. However, that was something that stopped when she began junior high, when her body went through some changes that made her self-conscious even towards her brother.
"You… Like this?" She asked very cautiously. Her eyes faced down towards his bulge that was waiting to be unleashed. Ayami brought her hands down to his crotch, pulling down his shorts to reveal his hard cock.
"I hope you're okay with this." He spoke shyly. This was the first time he had ever shown off his penis in this state to anyone. His small frame meant that it was a bit smaller than he would ever be confident with. There was the bit of fear creeping into his mind from the various hentai he had read involving girls laughing at a boy's small dick.
"It looks fine." She assured him. All the while, the girl had her eyes on it ravenously. Ayami had never seen a boy's dick in person like this. Sure, as she had taken baths with him, she was aware of what his looked like. But seeing it all hard and stiff like this got her pussy feeling very wet. To think that her little brother's little guy could do this to her. "Maybe we should-" She was about to begin the sinful act, but a knock at the door interrupted her.
It was their mother, who had felt a bit concerned when she saw her daughter return home in the state she was in.
"Oh, Ayami, is everything okay?" She asked as she entered the room. In the quick rush to hide from his mother, Arata had hidden himself under the bed sheets. At the same time, Ayami had also laid under the same sheets, pretending to be getting some rest. He was behind his sister, and thus not noticed by his mom.
"I'm fine." She responded, sweating bullets that they might be caught. If their mom saw them like this, that could make things very touchy within the family. Arata felt the same way, his head under the sheets. He couldn't see where his parent was, but he did his best to try and calm his heavy breathing to not be heard.
"It's just that I can't imagine getting rejected. I'm sure you must be hurting a lot." She sat down besides her daughter, making the siblings get more and more stressed they might be caught. "I just don't want you to hide yourself from the world." She continued on, reference her own son's plight.
"I promise I won't…" While those two were talking, all Arata could do was lie in wait. He tried to control his breathing, keep his heart calm. But it was near impossible given how close they were to being caught. Just the idea of the shame turned him on even harder.
Which was a bit of a problem seeing as he didn't get the chance to put away his penis when going to hide. He looked down his chest to see just how close he was to his sister's butt. Her slim, yet shapely butt that from the angle he was at. The boy could see his sister's violet panties. The crack of her booty just slightly visible and the sight of it making it even harder to control himself.
There was little space between the two, and soon his hard dick made contact along her butt crack. She felt it, which caused a bit of a reaction while talking with her mother.
"Is everything all right?" She asked, seeing her daughter tense up even more. This was looking bad for them. Ayami needed to come up with something to save them.
"I'm fine. Maybe I might be coming down with something."
"Oh, you poor thing. I can get you some medicine."
"I don't think I'll need it." She quickly responded. "It's a little light, so just some rest is good for me. Could you please leave u- I mean me alone?" Their mother was a bit disheartened at being kicked out by her daughter. However, she wasn't going to argue it and made her farewell.
"Try and get some rest. I'll come back in an hour or two." Then, she closed the door to make her exit.
Now free of that problem, Ayami immediately threw off the blankets to reveal herself and Arata out in the open.
"Arata, what are you doing?" She asked him, but he responded with action, rather than words. In a quick and swift motion, he tore down his sister's pants. Her bare butt and pussy were now expose for the world to see. "Arata, slow-" He covered her mouth, preventing more words from coming out. That was for what he was about to do next.
"I'm sorry, I can't wait any longer." He told her, then rammed his now fully erect dick into her vagina. Ayami loudly moaned in a mix of pleasure and pain as her virginity was taken from her. It would've been very audible, which is why he covered her mouth in the first place.
"Don't stop." She said after he took a moment to pause from his first thrust. "I… I want more." He started to hump his sister, in and out of her tight pussy walls. Never once in either of their minds, did they believe their first time would be with each other. This was wrong. There was so much wrong with what they were performing with each other. Their brains knew this, but their bodies craved more of it.
Arata knew he couldn't just simply keep trusting inside of her. Sure, the boy had practically no experience, but he did have the hentai he secretly read that even his family didn't know about. That might've been fictional, and based on absurd scenarios, but it was better than nothing.
So he took a hold of her breasts, which really got her going. Ayami felt like she was being assaulted by multiple sides, her brain was finding it difficult to focus on one area. There was a flood of pleasure moving across her body. Her pussy had already produced lot of sexual fluids just from what she saw of her brother earlier. Now it was being used to its fullest as lubricant as he shoved himself deepened in her tight vagina. Or more accurately, formerly tight as he loosened it up with his actions.
He opened her up even more as he picked up her leg. Ayami's pussy was even more exposed, if someone were to walk in right now. There would be no hiding it. This feeling was intense for the both of them. Not only were they having passionate sex, but it was under the taboo of blood related siblings. All right in one of their rooms, under the roof of their parents. Where both said parents were at home, and could easily walk in without permission if they wanted. Something that their father did plenty of times.
Ayami was glad her dad was so dumb though. For he had entered on her multiple times when she would masturbate, only to not be aware as she kept hidden under the sheets.
As for the current moment, there be no fooling him. If he came right now, he'd be greeted with the sight of his son railing his daughter.
The two of them were nearing climax. Obviously, it wasn't as if he would cum inside of her. But at the same time, Ayami almost wanted him not hold back. For her first time of ever having sex, she wanted to feel a man filling her womb. She just never expected that she'd be wanting her brother to be the one.
"I'm sorry." He said, as he gave her nipple a tight squeeze. With that, the boy took out his stiff cock and shot out his load. Ayami saw his hot slimy cum spread out on her sheets. Watching her brother get off from being inside of her put her body over the edge. It was a challenge to muffle her moans, as the pleasure was immeasurable. But if it was heard, then they'd be caught. This was the hardest thing she had to do, as she pussy squirted out the rain. Her bed getting soaked from her cumming.
The both of them were now satisfied. Their first time was complete and the two of them stayed silent other than their heavy breathing. Of course, things weren't finished yet as they scanned the bed. It was a big mess from the mix of lady juices and semen they produced. There was going to have to be a big clean up effort, because there was no way they'd be able to explain this to their mother.
