[Progress]Tachibana Kyouka's Lovey-Dovey Situation (Pixiv Fanbox)

This time, we have a love story between Kyouka Tachibana and Yuu-kun from "Tachibana-san's Circumstances with Men". Since Kyouka is the main character this time, the scenes featuring Yuika and Koharu are simplified.

[Character Introduction]

Kyouka Tachibana

Kyouka is the mother of Yuika and Koharu, estimated to be in her mid-40s but appearing much younger than her actual age. She raised her two daughters and Yuu alone after her husband passed away. Although she is an excellent company employee and speaks intelligently, she is weak to sexual pleasure. She has an attractive body that draws men to her, with a bust size equivalent to several meters (K-cup).

Yuika Tachibana

Yuika is currently a 20-year-old college student. She is Koharu's older sister and Kyouka's daughter. With her black, long hair, tall height for a woman, and slightly stubborn beauty, she is often called a "cool beauty." Her bust size is slightly smaller than Kyouka and Koharu's, but still over 90 centimeters (H cup), inheriting Kyouka's beauty and high sexual appeal. She tends to have a cold attitude towards men other than Yuu.

Koharu Tachibana

Koharu is Kyouka's daughter and Yuika's sister. She is 20 years old and a university student. Compared to Kyouka and Yuika, who have sharp beauty, Koharu has a gentle and laid-back appearance. She is academically excellent but has a slightly airheaded side to her. Among Kyouka, Yuika, and Koharu, Koharu is the most vulnerable to sexual pleasure. She is a perverted woman who selects men based on the size of their penis.

Yuu

Yuu is a 16-year-old boy who lives near the Tachibana family. He has had a relationship with the Tachibana family for a long time, but he started living with them after his grandfather, who was his guardian, was hospitalized. Both of his parents have already passed away. He had sexual relationships with Kyouka, then Yuika, and finally Koharu. Now, they have sex every day with the four of them. He is worried about his small and unimpressive appearance. His penis size is small (S size).

Main.

As I knelt on the bed, Yuika crawled towards me like a four-legged beast. Although she usually had a mischievous smile and teased me, at this moment, she had a lustful expression on her face, wanting my penis. It was frankly very erotic.

"You've got a naughty erection. Do you want me to lick it so badly?"

Yuika pinched the erection sticking out of my waist with her slender and long fingers. The sensation of being touched by someone else was completely different from when I masturbated with my own hand. Just having a woman hold my penis with her hand felt good.

"Uh-huh..."

I nodded obediently, and Yuika smiled with satisfaction. Then, she put the glans in her mouth and slowly began to drink it, tickling it with her tongue while slowly swallowing it.

"Ah!"

It was a sensation so intense that I couldn't help but let out a moan. It was hot and slick, yet soft and velvety, enveloping my manhood. My member disappeared into the warm, slippery space. With a look of ecstasy on her face, Yuika's tongue danced around inside her mouth, moving in sync with the motion of her lips sliding up and down my shaft. The pleasure was electric, sending shivers down my spine.

"Oh...," I involuntarily exhaled.

Yuika was so skilled at fellatio. She knew just how to handle my cock, and she hit all the right spots.

"Come on, move your hips more," she urged.

As she spoke, Yuika took my cock back into her mouth. I did as she asked and began to thrust my hips. The sounds of her lips smacking and slurping echoed in the room as my head rubbed against the walls of her mouth, mixing with her saliva.

"Mmm... slurp... ngh..."

Yuika increased the intensity of her head movements to match my thrusts. Every time her lips clamped down around my cock, I felt the pleasure of impending orgasm rise up. But I didn't want to come just yet. I wanted to savor this experience. It would be such a waste to come too soon with a beauty like Yuika sucking my cock.

"Yuu-chan, over here," Koharu whispered.

As I held back my orgasm, Koharu, who had been waiting on the side, hugged me from behind. I turned around and felt the touch of her big breasts, which were over 100 centimeters. Her calm beauty was right in front of my nose. We couldn't resist each other's breath, so I put my hand on the back of Koharu's head and kissed her.

"Mmm! Chu...Nn, Nn!"

Koharu entwined her tongue while wrapping her arm around my neck. Her sexual skills were still developing, but they were more than enough to be pleasurable. Secretly, I evaluated Koharu as the sexiest woman in the family. I don't want to use words like "lewd" towards my lover, but she's weak to pleasure and loves anything that feels good. Maybe it's because Koharu is honest and doesn't have any hidden personality. After all, there's no human who hates things that feel good, right?

While enjoying the feeling of our tongues entwining, I reached out and touched Koharu's breasts. I kneaded them with the palm of my hand and caught her nipple with my fingertips. As I played with it, Koharu began to moan.

"Aah! Yuu, you're so...but, I like it ♡"

There are websites on the internet that write nonsense like "big breasts are insensitive because the fat is thick." But that's not true at all. Koharu is sensitive, and she easily reaches climax with just a little bit of stimulation. She's even convulsing just from a light touch on her chest right now.

It's like the kind of easy heroine that appears in AV and erotic manga stories, who gets aroused easily just by having her breasts played with and being kissed, but with a cute and sexy body like hers.

"Koharu-sis, even if another man does something dirty to you, you can't follow him."

"Uu... I know that..."

Koharu responds with a melting expression, but I'm not sure if she's actually listening to my words, which only makes me more anxious.

"-Ouch!"

I feel a sharp pain in my crotch and involuntarily scream. It seems that Yuika bit my penis. It was only a slight pressure with her teeth, but it surprised me greatly.

"Hey, you," Yuika looks up at me with a fierce expression in her eyes. "Do you think we're easy women who would follow any man other than you?"

"N-no..."

"Then shut up and keep your penis erect, idiot."

As Yuika resumed fellatio, my penis became covered in her saliva but she licked it all up with her tongue.

"Mm... Nn... Juruu!"

She swallowed my penis all the way to the base and licked the glans with her entire tongue.

I inadvertently groaned, and her tongue wrapped around the corona as if to apologize.

"Since Yuu's penis is all we have, we can't afford to think about unnecessary things. I'll make sure to enjoy it properly," Yuika said while rubbing my cheek against my penis.

"Yes..."

"I'll make you feel good too, Yuu-chan."

Koharu's hand reached out to my nipple. Perhaps she thinks that her weakness is the other person's weakness. Her fingers gently stroke my nipple, causing my body to tremble slightly. Koharu smiled as she watched my reaction. And she whispered in my ear.

"It feels good to have your nipples touched, doesn't it? Boys feel it too?"

"Uh..."

I nod honestly. It's impossible to hide it when I'm reacting this much.

"I'll make you feel even better. Will you make me feel good too?"

"Yeah..."

"Thank you. I'm happy. Hehe ♡"

Koharu, who heard my reply, approaches my face and kisses me. We continue to fondle each other's nipples while embracing each other.

I call them Yuika-sis and Koharu-sis, but we are not blood-related siblings. We live together due to some complicated family circumstances, but legally and biologically, we are just strangers. That's why we can have sex with peace of mind.

Yuika, also known as Tachibana Yuika, is a beautiful woman with long black hair that catches your eye. She has slightly sharp and assertive features, and at the university she attends, she is known as a "cool beauty." But at home, she's a mischievous older sister who teases me. Cool beauty?

Koharu, also known as Tachibana Koharu, is Yuika's younger sister. She has light brawn long hair and big round eyes, and she's a beautiful woman with a cute and gentle older sister vibe. If Yuika is a beautiful woman with a cool image, then Koharu is a beautiful woman with a cute and gentle image.

Yuika and Koharu are both so beautiful that they were asked to compete in a beauty pageant. Their breasts are also quite large. I secretly enjoy watching adult videos, but Yuika and Koharu have bigger breasts than most AV actresses. Their mother, Kyouka Tachibana, also has big breasts. I always use AV as a call to fantasy. Once the image is formed, I imagine Yuika, Koharu, and Kyouka replacing the actresses. Then I pretend to be an AV actor and violate them.

With such erotic women having sex with me every day, why do I need AV? Real sex that I experience and the unusual sex I watch in AV give me different types of excitement.

"Yuu, are you about to cum?"

Yuika talks while still holding my dick in her mouth. The vibration is transmitted to the glans and feels amazing.

"Yeah, I'm gonna cum..."

"That's good, be honest. You can cum now. Come on, do it quickly."

Yuika deeply swallows my dick and squeezes the glans in the back of her throat.

"Ah, ah, ah!"

The moment I ejaculate in Yuika's mouth is the best feeling ever. I don't think I have a sadistic side that enjoys dominating or hurting women, but the moment of ejaculating in the mouth of a beauty like Yuika while she's still holding my dick in her mouth is the best feeling. The pleasure of feeling like I have the privilege of defiling her beauty makes me dizzy.

Yuika seems to know that too, so she encourages me to ejaculate by swallowing my dick down to the base.

"Ungh! Nnn! Nnnn!"

As ejaculation starts, Yuika seems to be enjoying the sensation of semen spreading all over her mouth as she moans in pleasure.

"Heheh...Nfuu...Ngu...Nnu..."

Yuika sucks on my penis as if trying to get every last drop of semen out. The pleasure of having any remaining semen sucked out of my urethra causes my body to tremble.

"Phah...Nfuu...Heheh...Thanks for the meal."

Finally, Yuika releases my penis from her mouth and uses her tongue to clean up the semen on her lips.

"Yuu-chan, I'll take care of you next."

Koharu separates herself from me. The competition between these beautiful sisters in their fellatio skills is certainly enticing, but I'm already impatient to stir up their vaginas. Even though I just ejaculated, my erection shows no signs of abating.

"Yuu wants something more than a blowjob," said Yuika, reading my desire. She was the eldest sister, after all. She understood my sexual preferences.

"I see. Yuu-chan also wants to feel good with her pussy more than her mouth, right?"

"So, who do you want to go first?"

Koharu hesitated, while Yuika stared at my penis challengingly.

"Since it was Yuika's mouth that made my penis erection, I think it should be Yuika first."

Hearing that, Koharu lowered her shoulders in disappointment. Yuika saw this and smiled triumphantly.

"Koharu-sis, it's your turn now after Yuika-sis."

"Okay. It's a promise."

"Of course."

I reminded myself not to ejaculate too soon in my excitement from Yuika.

"Then, shall I get fucked from behind?"

Yuika turned her butt towards me and went on all fours on the bed. Her body was perfect in every way with her well-shaped hips, smooth back, toned waist, and ample breasts.

"I'll put it on for you."

I couldn't believe that I was having sex with such a beauty every day. I was still in a daze when Koharu approached me, tearing open the condom packet. She then put the pink contraceptive on my penis.

"This is all set. Big sis is waiting, so hurry up and do it," said Koharu.

I grabbed Yuika's buttocks with a heavy breath and inserted myself all at once.

"Ahn! No, a little less forceful ♡"

Yuika seemed surprised at the sudden penetration, but soon began to breathe heavily with pleasure. I had been holding back, so I moved my hips intensely.

"Ahn! Ahn! Ahn! Ngu... Nn! Nn! Nn!"

Yuika's vaginal walls tightened around my penis. Our bodies, having repeated sex many times, had memorized each other's shape. It felt like a puzzle fitting perfectly together, and it was so pleasant I couldn't stand it.

"Yuu-chan, does it feel good?"

Koharu, who was sitting right next to me, was staring at the place where Yuika and I were connected. When I nodded in response to her voice, she smiled with satisfaction.

"Yuu, I love you ♡ I love you so much ♡"

Yuika gripped the sheets and pushed her face into the pillow as she moaned. Her voice had a sweet timbre that tantalized my heart just by listening to it.

I covered her back and pulled her body close, kneading her breasts. Yuika shuddered with each movement of my hands. Every time she did, her vagina contracted, squeezing my member tightly.

Yuika turned her face towards me, and I leaned in to kiss her. But just before our lips met, I stopped. Yuika loved to kiss, and always wanted to do so during sex. But not now. I wanted to hear more of her lewd voice.

"Ah, ah, ah! There, right there, that's good!"

Instead of stuffing Yuika's lips, I kissed her neck. As I licked her sweaty nape, Yuika wriggled like she was ticklish.

Yuika is four years older than me and a college student. I get excited seeing such an adult woman enjoy being violated by a boy like me.

"Ah, ah, Yuu, Yuu... No, while licking it like that ♡," pleaded Yuika in a voice without composure.

I felt a gaze and looked beside me, where Koharu looked at us enviously. Koharu, too, seemed excited, with rough breathing. Her face was flushed, and her eyes were watery.

When I beckoned, Koharu crawled over to me on her knees. With my free hand, I touched Koharu's pussy. She shook her body as if surprised. Her pussy was already wet, and my finger easily slipped into the warm hole.

At first, I moved my hand slowly, spreading the slippery liquid overflowing from the back of her pussy over my entire finger. In no time, my index and middle fingers were wet from the tip to the base with Koharu's sexy juice.

"Hyauu, nnn, nnuu!"

Koharu's pussy gently hugged my finger. I slowly, yet forcefully, stimulated her G-spot.

"I-it feels good, but don't touch me there!"

"Why not? It looks like it feels really good."

"I-it feels too good, I might become strange."

"Koharu-sis, you're so cute."

I relentlessly attacked Koharu's weak point. She shuddered all over her body while enduring the pleasure.

"I'm gonna come...I'm coming!"

Koharu let out a loud scream and climaxed. She leaned against me while still on her knees. When she came, she lost her strength and couldn't stand up on her own.

"Haa...haa...I told you to stop already..."

Koharu nearly collapsed onto the bed, but managed to regain her composure. However, her body was still in heat, and she occasionally writhed and let out hot breaths.

"Koharu-sis, did it feel good?"

"Yeah...it felt really good..."

Koharu nodded shyly. Seeing her like that made me want to please her even more.

"Hey, you two shouldn't be getting too excited by yourselves. You haven't forgotten who you're sticking your dick into, have you?"

Yuika's voice, laced with irritation, interrupted our gaze. Well, if a man who was fucking her was staring at another woman during sex, she wouldn't be in a good mood either.

I apologized obediently. "Sorry, Yuika-sis. I'll make it up to you by moving a lot."

"I mean it. Move your dick properly."

With the hand that was still wet with Koharu's juices, I grasped Yuika's butt and started to move vigorously with all my might. I pounded her harder than before, slamming my hips against hers. The dry sound of flesh hitting flesh echoed through the room.

Yuika moaned in response to my intense thrusts. Her voice sounded even louder than before, and I was glad to think that she was getting excited too.

"Oh, yes! Amazing, amazing!"

Yuika's insides were tight and hot, squeezing my cock like a different creature altogether. Worried that the condom might slip off from the pressure of her tight vaginal walls like a vise, I frantically pumped my hips while holding back the urge to cum. But the limit was reached in no time. Unable to hold back my ejaculation any longer, I stopped moving.

"What happened? Why did you stop all of a sudden?" Yuika asked.

"I'm about to cum," I replied.

Already, a few drops of semen were mixing in with the pre-cum. I said it in a pathetic voice, and Yuika chuckled.

"Are you about to cum?" she asked.

"Yeah," I replied.

"Well, it can't be helped. Go ahead and cum," she said.

Yuika lifted her buttocks and guided me towards my climax. I didn't resist and moved my hips, squeezing out my last bit of strength.

"I'm cumming!" I exclaimed.

"Mmm... it's coming out..." Yuika moaned.

With the head of my cock pressing against Yuika's cervix, I came. Through the condom, I could feel my semen being released in spurts.

"Ha… Aah… Huh… Did you cum everything?" Yuika asked.

My erection, which was bouncing in her vagina until earlier, is now quiet. However, it hasn't gone flaccid. It has become a little soft, but it will quickly regain its hardness with a little stimulation.

"Koharu is waiting next."

Yuika said this as she removed the condom from my penis. After tossing it in the garbage can beside the bed, which was mixed with semen and cream, she reached for a new contraceptive.

"Shall I clean it up before I put on a new one?"

Saying that, Yuika licked my penis covered in semen. She carefully licked off the white jelly that stuck to the folds and the head with her tongue and sucked on the base while pressing her tongue against it. She removed everything that had adhered to my penis until it was clean.

Yuika put on a condom on my clean penis.
