 Chapter 12 - Siblings Are Not Supposed To Have Sex With Each Other. (Part 2)

"────...... hah...... ah...... Miyu......!"

 Sure enough, I had been stimulated my penis by Miyu's in the shadows of the kitchen since the sun was still high after school. Miyu was kneeling on the floor, her ample breasts clamping her erect penis.

 My meat stick, which had increased in size by two sizes since just a few months ago, was sticking out of the fat of Miyu's breasts instead of being buried in them. The glans peeked out from the cleavage whenever the squashed twin dunes bobbed, and Miyu stared at it with a sullen but upturned face.

"How's it going, Onii-chan?"

 Miyu looks up at me with a worried look on her face. I stroked Miyu's head, trying to sound as gentle as possible, calming her excited breathing.

"Don't worry, it feels so good. I'm about to ejaculate already."

 When I told her that I meant it, Miyu made a miffed face and glared at me.

"That's not what I meant. I'm asking if you don't feel guilty about letting your younger sister give you a titjob."

"That's ......... ...... ah... ...... wow, your said she was sorry ......!"

 Miyu excused herself from the punishment and squeezed my penis between her tits harder. I was dressed in a shirt and bottom half, and Miyu had taken off her uniform to avoid getting dirty from the lotion, and was wearing only a pair of pants and high socks. The uniforms we had taken off were set on the floor for both of us to be aware of our status as students.

 They are still young students, older brother and younger sister, having naked touching in the kitchen of their parents' house in the light of day. There was no way I could have known what this was if it wasn't immoral, but my libido was rising and Miyu was having sexual experiences with my brother under the guise of scolding me for it.

"You don't seem to feel bad at all over here."

 My meat stick, which I had just ejaculated a lot this morning, was now hard and ginormous again in Miyu's tits, making the space between her breasts slick with her enduring juices. I'm having paisley sex with the idea that if I reduce my semen and suppress my libido, my rational mind should abstain from sibling sex.

"Hey, hey, Miyu. If you plan to have Yamamoto-san cure you of the fact that you can only cum with Miyu, then you don't have to avoid sex with your siblings anymore, do you?"

 I'm in trouble now because I can only lust after Miyu, and if I can have sex with other girls, then there should be no problem with me being able to have sex with Miyu.

"I told you, that would be a problem for me."

 Miyu stops pizzing me and looks up at me with a complicated expression on her face.

"What's troubling you?"

"You're aware of that, Onii-chan. I'm starting to enjoy doing this too. At the very least, I want you to tell me that I shouldn't have sex with you."

 Miyu's eyes are moist as she pleads with me. What she means by that statement is that she can't stop herself from wanting to have sex with me anymore, so she expects me to tell Miyu that she shouldn't have sex with her siblings?

"How much do you enjoy it? Are you going to be able to do that ...... blowjob or something like that ......?"

"Say that again. If I can give you a blowjob, there's nowhere to go back to."

 That was the reason Miyu wanted to avoid blowjobs at all costs. If I could give her a blowjob, then she would be completely convinced that she could have sex with me.

 But it was also true that it was the only way to be sure. So, to her best effort, Miyu extended her tongue and licked around the tip of the meat stick that had poked its head out of the cleavage.

"Ugh,...... ah,...... soooooooo,...... haaaa,haaaa,...... Miyu's tongue, oh my god! It feels so good, oh no, I'm going to ...... get it!"

"Heck, rheroo...... ugh,......, Onii-chan will ejaculate no matter what you do. ......"

 Miyu didn't seem to have any problem with licking either, and since it was no longer too late, she should have just sucked on it, but she just let the tip of her tongue crawl over the prick and licked around the callus and underside like she was twirling a tentacle.

"Oh ...... ohhhh ...... I'm cumming already, Miyu, drink it ......!!!"

 I held Miyu's head down and lifted her hips up, then poured the cum that shot out like a fountain into her mouth. Some of the semen was sent from the bottom to the top and leaked out of Miyu's mouth, dripping onto her tits, then running along the curve of her tits and falling to the floor.

"Nnghhh ...... nggg, hah...... why is it so thick after all that I put out in the morning......?"

Miyu swallowed the semen and licked off the residue of the semen that had come floating plumply to the bell mouth while she stared at my penis with a grudging smile. She had done everything I had ever wanted her to do, and I still didn't feel guilty about it.

"How was it Miyu?"

"Nothing ...... nothing ......."

 Miyu's troubled eyes rolled to the side and she kept her mouth shut at the answer she didn't want to get. She didn't have any qualms about licking my penis. Well, I knew, and I guess if I gave her a pacifier blowjob, I would ejaculate the same way, and Miyu would drink the semen the same way.

"Ugh ...... I guess I'll just have to give up now ....... Onii-chan, please try your best to get it out with Kanade-san."

 Miyu lamented as she unfolded the clothes beside her and put them on, starting with her bra. Miyu's position as she hooked it on looked painful, which was unusual for Miyu, whose body was supposed to be soft. Her breasts were also not fitting into the cups, and she tilted her head back after adjusting them several times.

"Ugh ...... what should I do ...... my boobs might have gotten bigger ......"

"Maybe it's because you're having sex with me?"

 I wondered if my boobs had grown because of the stimulation from the titjob. I half meant it as a joke.

"That's all you've got, though. Already. Take the blame."

 But even as Miyu, she seemed to agree with that. I'd like to take the responsibility, but I have to be good friends with Yamamoto-san from now on.

"That's enough. Do you have any free time during summer vacation, Kanade-san? You're popular, aren't you?"

 After getting dressed, Miyu took a cup of tea from the fridge and poured it into two cups. She had sweated and cum a lot, and it would be hard to get dehydrated.

"I heard she has a part-time job at a tavern. But other than that, she said she has a few plans to go out with his friends."

"Hmm. I guess Onii-chan has a short-term job as well, so maybe their free time fits together."

"Right. Miyu, are you traveling again?"

"Yeah. Haruka and I are going to stay over for about a week."

 Miyu takes long trips around this time of year. Haruka's family is rich, or maybe they have a vacation home.

"I'll keep my fingers crossed that my younger sister sissy-compatriotism will be cured when I get back."

"Right. I'll do my best."

 I'm happy to be able to have sex with Yamamoto-san, but I'm going to miss having Miyu drink with me.

"Hey, hey. Don't make that face."

"Because if it works out, you and Miyu will no longer be ......."

"Because that's the way it should be. And ......, I'll drink with you at least until I'm done with Kanade-san. Right?"

"I see. Yeah, then, I'll do my best."

 We both know that this is not the time to stop the immorality of having sex with a older brother and younger sister. But since I already like Miyu and Miyu has grown to like having sex with me, a compromise decision was implicitly made that it would not be good for either of us to suddenly stop.

"As for Miyu, if you only do it with your tongue, doesn't that count as a blowjob?"

"Yes. Even if I did, I wouldn't do it again. There's no end to it."

"Then, just one last time. I have a favor to ask you."

 I pulled my erect penis out of my pants as I talked to Miyu.

"Um, Onii-chan. That's already the third time today, right? Are you kidding me?"

"I can't help it, you know. Ever since I started doing it with Miyu, I've had a huge sex drive ......."

"Wow, don't make it sound like it's my fault. You've already done it yourself."

"I know. I'll do it myself, can you just use your tongue to do the tip, please?"

"What do you mean?"

 Miyu didn't seem to understand what I was requesting, and when I pointed the tip of my erect penis at her, she sat down in front of it, folding her knees.

"Like this ...... because I'm shimmying myself ......."

 I resumed masturbating in front of Miyu again. I was as excited as I was before I ejaculated, with Miyu in her uniform in a position to catch my semen.

"Can you please lick the glans, the part where the skin is flipped up, with your tongue?"

"I think that is indeed too naughty on my part. ......"

"You did something similar for me earlier, while you were pussying me, didn't you? So, you know?"

 While we're talking, I rub my penis and give it as much stimulation as it needs to ejaculate. If I reasoned with her about something, this little sister would finally do me a favor.

"Ha, ha ......! Miyu, please ......! Tongue out, just lick the tip of it......!"

"Woo...... don't ask so desperately......!"

 Miyu looks troubled and is on the verge of giving a blowjob, repeatedly pulling her tongue in and out. I knew from previous experience that Miyu would show little resistance to the act once she had experienced it.

"Miyu, please ......, I'm going to get out now ......."

"I know, I know. It's just for today."

 Miyu decided that she had no choice and poked her hands on the floor and extended her tongue to my glans. I switch to masturbating, rubbing my fingers on the underside of the glans instead of the callus to keep the skin out of the way. The bloodshot tip felt slippery and moist from Miyu's saliva.

"Ahhh, ahhh...... Miyu, that's good...... very good......!"

"Heck,...... nnnn,...... onyan,...... this feels so naughty.... ..."

 I stick out my panting meat stick, and Miyu chirps and licks the tip of it. It was nothing short of lewd to see my younger sister, still in her back-to-school form, licking the cum-producing part of my penis with her tongue in a circular motion.

"Miyu, I'm going to cum, I'm going to cum again, just keep drinking ......!!!"

"Nnnn, fuu......hero......reroku............ hurry up, Rahihe! Nnnn......!"

 Finally, I gripped the gorging meatball and I thrust my hips out further, bringing my penis up to the top of Miyu's tongue, where I spewed at point-blank range. The liquid, which was indeed a lighter white color, flew out, and Miyu kept her mouth open, dutifully waiting for me to finish my ejaculation. When I pulled out my penis, Miyu gulped down the semen, her blushing face set to teeth.

"Onii-chan is making me feel naughty."

 These days, Miyu's statement was straightforward.

"Then, do you want me to finger you too?"

"That's fine. I'm embarrassed to be seen cumming, so I'll go finish by myself."

 When I was disheartened by Miyu's refusal to allow me to touch myself even after all this sex, she left me with the advice, "Don't eavesdrop," before returning to her room to masturbate.

"Miyu sounds so cute ...... when she feels it ............ I want to hear it again ......."

 Alone in the living room, wallowing in my feelings for Miyu, which were increasing day by day, I finally had an endless overflow of desire. Just let me have that pseudo-sex with just the tip of my pubic area in, and let me do it again. I just wanted to hear Miyu's voice as she felt it, rather than how good it felt to insert it.

"Why don't we go to her room and talk about it?"

 Then I went to Miyu's room and got the usual scolding for interrupting her masturbation. After that scolding, I took advantage of the fact that Miyu was so horny - in fact, she wanted me to do it - and we repeated the same tip-only pseudo-act with Miyu many times from that day on.
