"You are such a jerk, Tai!" yelled Sora and slapped Tai right in the face. Before he could react, a few tears gathered in her eyes, and she ran off. Upset by her reaction he touched his cheek that still hurt a bit.

"Some friend Sora is. All I wanted to do was getting a tiny little feel for her breasts, but she blows her top." He muttered under his breath while he walked back to the Kamiya's apartment.

"Hello, is anyone home?" he yelled into the apartment while he closed the door behind himself, but he got no answer. Tai checked his cell phone, but he had received no message. "Guess I'll just have to settle for dad's porn movies again. But where did he put them." He spoke to himself.

Just when he was about to open the door to his dad's office, he heard some sound from his room, "Shit what's that?" he thought. He put his ear at the door to hear a bit better, this time the sound was a whimper, a stutter, "Br…th…r…" was the only thing he heard from a female voice.

Silently he opened the door to his room and peeked into it, what he saw was not just utterly surprising, but also gave him very conflicting feeling. His little sister lay upside down on his bed, her head buried in his pillow and her legs spread wide. She wore nothing, but socks and a shirt, while her hand furiously stroked her pink, wet pussy. He couldn't stop watching his sister masturbate while her sweet moans reached his ears.

Forgotten were all thoughts he had spent on Sora, watching his sister in such a position brought a new idea to his mind. "Maybe…I could be Kari's boyfriend…Why not?"

Maybe it was just a coincidence but when that thought crossed his mind Kari's moans became a bit louder. Tai just became even more curious and aroused when Kari became louder and didn't try to muffle her moans anymore in his pillow. Instead, she brought a second hand to her dripping sex, one hand spread her labia as wide as possible, while the other frenetically rubbed her tiny love button. Her back ached and her head fell back, moans turned into little screams of pleasure, while her hands moved faster and faster.

At this point Tai's pants were already down to his ankles, and he was stroking his erect member with the same intensity as Kari pleasured herself. But what he saw was not enough for him and me made a few steps into his room, careful not to trip over his pants.

Kari didn't notice him she was I her own world of lust, thrashing the bed with one fist, while she was so close to her sweet release. She pushed two fingers into her extremely wet folds, "Brother…big brother." She screamed when she reached her peak and waves of pleasure rushed through her body.

Heavily panting she let her body fall onto the mattress, just the friction from the bed sheets gave her a little aftershock. "Big brother," she mumbled again still lost in her own fantasy of lust. She hadn't even noticed that Tai had come to the edge of the bed, still stroking his member that had become harder with every small step he had made towards his sister.

He wanted to resist, but he couldn't, his unoccupied hand moved like it was acting on its own caressing Kari's body for a second, before his hand clutched one of her ass cheeks, lustfully kneading the firm flesh. With a surprised yelp Kari suddenly realized that she was no longer alone in Tai's room. Frightened she turned her head to see who was behind her.

Behind her stood Tai, her brother. His cheeks were red like tomatoes, his eyes filled with lust, and he was stroking his massive member. "Big brother," she said relieved and embarrassed, but also turned on by the sight of her brother's impressive boy parts.

"You were asking for this by being in my room." He said huskily, while he increased the speed of his hand motions.

"B…but…Tai…" she wanted to respond, but it was already to late the thick, red, shimmering glans were pointing at her and his face became a grimace. He moaned loud and splashed several spurts of his seed onto his sister, hitting her first in the face while the other spurts hit her shirt covered breasts.

After spraying his cum on Kari, Tai suddenly realized what he had done and tears of regret filled his eyes. "Uh…I…," he wanted to excuse to Kari but the words got stuck in his throat.

"…It's okay…if you liked it, Tai…" said Kari between pants.

Tai really had not expected from Kari to say something like that. "Kari," he whispered.

"Don't worry Tai, I saw you before doing it and I always hoped for more…" said Kari with a blush, looking at her brother with big eyes.

Before Tai could answer her, she leaned towards him and wrapped her hands around his semi erect member. She moved closer and closer until her face was directly in front of his member, with pink cheeks she planted loving kisses on the sensitive tip, moaning slightly.

"H-Hey! K-Kari…" he stammered.

Kari looked up meeting his gaze with her big brown, love filled eyes. "Does it feel good Tai…?" she asked joyfully.

"K-Kari…" he panted heavily, while she started to suck on her brother's big cock with gusto. Tai's massive member was way too big for her tiny mouth, so she switched to affectionately licking the whole length of it. While she really enjoyed pleasuring her brother with her mouth, Kari felt her own sexual desire arise again.

She grabbed Tai's wrist and pulled his hand towards her needy crotch. "Touch mine, too…big brother…"

Tai was very happy to return some favour she had given to him, carefully he used his middle finger to stroke the area between the outer lips. "Mmm… Right there…" she moaned when Tai's fingers focused on her pink button.

The moans heard turned into tiny screams when he inserted his finger into her tight, wet hole. Tai smiled when he looked at his sister, her cheeks were in a deep shade of pink and her eyes were shut tight, moaning and screaming in pleasure.

"Isn't this wrong?" he asked still concerned about the well-being of his sister.

"It's fine…It's okay Tai. It's really okay." She said happily, pushing her pelvis against his fingers.

He slipped a second finger into her increasing her pleasure. While he was enjoying a lot what they were doing it was not enough for him, Tai wanted more. "Now or never," he thought.

"C-Can I put it in." he asked shyly.

Kari looked at him with big eyes, this was the most embarrassing thing ever, but she also wanted this more than anything else. "Yeah, Tai…you can put it in…" she answered and put her hands over her mouth as soon as she had said the words.

Tai took his member and rubbed the tip against Kari's sensitive folds, drawing out more of her beautiful moans. Feeling the slickness of her pussy he slowly pushed into the tight, wet hole; until he reached her hymen.

"Ah, ah…Oh…big brother, your cock is inside me…" moaned Kari excited.

"Kari are you okay?" asked Tai, concerned that he was probably hurting here.

Kari smiled at him happily, "Yeah…I feel great. It feels really nice…Please do it more…"

Tai nodded and kissed her perky breasts, quickly moving on to suck on her rosy nipples. Kari let her head fall back and let out a scream of pleasure. At this moment Tai jolted up his hips, tearing her maidenhood and entering her completely.

"I'm sorry Kari, but you feel so amazing." He held her close hoping the pain would go away soon.

"Ah…bi…big bro…brother," ignoring the pain of losing her virginity wasn't very hard for, since she felt so good with her brother balls deep inside her.

"Ah! Ah ah…! Big brother, give me more…," she pleaded, feeling the increasing heat in her core.

Tai pulled her up to have her sitting on his lap. Kari immediately used the opportunity that was given to her and moved her hips as fast as she could. He quickly mirrored her face pace hitting her so deep with his magnificent cock. The coiling heat in her core became more and more, she knew that it wouldn't take long until her sweet release would come.

"Ah! Ah! I'm gonna cum so hard…Tai." She screamed in lust filled pleasure.

Kari felt her limbs go numb from all the lust that filled her mind, she couldn't keep up her pace anymore and fell back onto the mattress. Luckily her brother was there for here he held her legs and mercilessly pushed inside her, making her scream louder with every thrust.

Kari became just a quivering mass under her brother, until eventually his big cock sent her over the edge and massive wave of orgasmic bliss washed over here.

Tai felt his sister's pussy suddenly tightening when her sexual screams became the loudest, he was barely able to move anymore. Kari's pussy had sucked him in, and he felt like her pussy would never release his dick again, but he knew his responsibility At this moment. He barely managed to pull out his prick in time before he splashed his seed onto her from head to bellybutton.

They both fell heavily panting on the bed. "Big brother," murmured Kari over and over again, until Tai embraced her and held her tight.

Kari happily snuggled up to him, "I love you, big brother."

"I love you, too, Kari." Said Tai and kissed her forehead, before they fell asleep.

Against my initial thoughts I decided to give this story an internal lore according to my headcanon. Chapters will now be uploaded in a chronological order as they happen in my headcanon.
