My Big Sister Teaches Me How to Make Love With a Hard Penis
“Non-erectile sex……?”
Non-erectile sex. Those two words didn’t belong together at all. I’d heard the phrase “non-erectile ejaculation” a few times on the internet, but I had no idea how any of it could be sex in the real sense.
“You don’t have to get hard to ejaculate, right? Not everyone can, like me. Most people have non-erectile sex, don’t they?”
“……How exactly does it work?”
I genuinely had no clue what non-erectile sex even was. How could you ejaculate without getting hard?
“Well…… a woman slides her fingers in from behind and stimulates your prostate until you cum.”
To my question, my sister gave me a slightly puzzled look, as if to say, “Why are you asking such an obvious thing?” It had to have been the prostate massage that forced the ejaculation out of me. Just hearing about it made my balls tingle.
“Prostate stimulation to make you cum? That’s not hard, is it?”
“It’s not easy, but everyone learns it in mandatory education. They even practice on dolls.”
“Mandatory education?! So everyone can force a man to cum with their prostate?”
“Even if they’re not skilled, they must all know the theory, right?”
It was shocking how normal non-erectile sex in this world had been insanely rare and special in my old world.
‘I guess that’s why there were so many weird videos that only showed a man’s ass being teased or played with in porn. Was that actually the standard sex here……?’
Almost every video I found in my research featured the man’s rear emphasized, teased, or something shoved inside. No wonder ordinary sex here felt terrifying.
“If I have to be more precise, even in non-erectile sex, if you stimulate the prostate hard enough you’ll get forced to get hard right before you cum. Then you quickly insert and fill the vagina with semen.”
Fingers in from behind, stimulating the prostate, and only inserting when the moment felt right, then receiving the creampie inside the vagina.
It was too perverted even for me. Way more twisted SM play than just a guy getting face-fucked or moving around because he came on his own.
“Well, compared to normal insertion sex, it probably lowers the pregnancy chance even more because a lot of prostate fluid mixes with the semen, making it thinner anyway.”
“I see…… I’m glad you told me. I had no idea at all…….”
“Isn’t that just basic common sense? How could you forget?”
“Somehow I don’t remember anything lewd even if it happens.”
I’d added a memory-loss setting that made lewd things especially forgettable. It wasn’t really a lie, since I had no idea about any of this in this world.
“You were having sex with a woman even without knowing about this?”
“……It just happened.”
Looking back, it made sense that my sister had been shocked and surprised by my hard penis. After all, having a penis that could get this rock-hard on its own without any help was seriously impressive.
“Well, having such a fantastic dick means there’s nothing to worry about.”
My sister, who’d been staring with envy, lay down on my thighs and lightly tapped my softening penis with her fingers.
“W-wait. Sister?”
“It was huge even when you were little. Other guys could barely get hard even if they tried.”
At her praise,
twitch, twitch…… whoosh.
“Huh?”
Blood rushed in, and just like that I got rock-hard again. I’d barely been focusing on something else to calm down.
“You get hard just from tapping? That’s way too easy.”
“It’s because you praised me…….”
I felt embarrassed and rubbed my sister’s back like I was taking revenge, then grabbed her overflowing, firm ass with both hands. My sister let out a small moan “Hyuk—” and glared at me.
“You know, when we have sex you spread your ass too much. Sister’s asshole…… is that why you love looking at it?”
“I love it. Every time you thrust in, my whole body twitches. It’s super cute.”
“W-well, everything about you is cute, you pervert!!”
She gave such a fun reaction that I actually wanted to do it again. Later I wanted to fuck Ji-eun and Boyang too, both of them would probably react just as cutely.
“So now that you’ve lost all resistance to sexual things, right?”
My sister rubbed my penis lightly up and down and asked. It wasn’t meant to make me cum; it was just a pleasant caress.
“Yeah. I felt really good just now too.”
I reached further and gently tickled the inside of her ass with my fingers. Since we’d already had such an amazing sex (aside from the thing I’d been holding back), I didn’t plan to go further, but if she was touching me, I’d return the favor.
“I see…….”
My sister shivered slightly at my touch, as if she loved it. Then she pulled one of my thighs toward her body, spreading her legs. The pussy hidden under her pubic hair was hot and soaking wet.
Schlick, schlick, schlick…….
“So now you want to take the Erectile Technician license?”
My sister rubbed my rock-hard penis and looked up at me while asking.
“……Erectile Technician?”
Too flustered by how lewd and charged the mood felt that no words came out.
“With you, even the National Erectile Technologist license would be instant. You’d probably get the Unlimited Sex License too.”
National Erectile Technologist? Unlimited Sex License? That sounded like code name 007. I bet my code name would be 074.
“You don’t know?”
“I don’t know…… I guess I didn’t try before?”
“Yeah. You said you didn’t want to show off because you were self-conscious about your big dick.”
It seemed my old self had been embarrassed about his huge penis too. Thinking about how different people’s views on dicks are in this world, it’s almost funny.
“What would I even do if I got it? ……Have sex?”
“I don’t know the details either. Maybe submit semen samples for male sexual function research, help produce videos that boost sexual desire, or become a related civil servant.”
A civil servant who helped make videos? Like a national porn actress? It was way more concrete and better than the fantasy of making money with my old dick.
“……Having sex with a woman I don’t know feels a little uncomfortable.”
But honestly, I felt a little repulsed by the idea of having sex with a woman I didn’t know.
Maybe it was because I already had three amazing women. Right now I was barely able to keep up with messages from all three at once; I didn’t know if I could handle more.
“Wouldn’t that be impossible? Getting hard under pressure from a woman you don’t know would be tough, right?”
I nodded in agreement, but the memory of my old interview came flooding back.
The cold, busty, short-haired interviewer’s gaze. Me getting hard under that stare, hearing the words “disgusting,” and being kicked out.
“……Yeah. Probably.”
I buried that memory deep and agreed with my sister. It was something I never wanted to think about again.
“Anyway, you said you’ve lost all resistance to lewd things. If you want to do it, just tell me. It’d be a waste not to claim such a fantastic dick. You deserve to lose nothing by taking it.”
As she said that, my sister pulled the skin of my hard penis tight, exposing the tip completely.
“If you want to try, I could even become your partner.”
She then lightly pressed her soft, warm lips against the side of the tip. Feeling those lips on my dick was always incredibly pleasurable.
“……Yeah. I’ll think about it. I want to learn more too.”
“You can do it with your girlfriend. It’s your choice.”
My sister said it was fine, but she kissed my penis again, this time taking the tip inside her mouth and starting to give me head.
“Chuuup, slurp. Haa, lick, lick, chuuup……♡”
It was a blowjob that made her cheeks hollow out, teasing my most sensitive spot relentlessly, as if she couldn’t bear to give it to anyone else.
“Your words and actions are completely different, sister.”
“Lick, lick, suck♡ Slurp, slurp, bob♡”
My sister didn’t answer and instead rubbed her tongue under the head of my penis. I couldn’t hold back and spread her pussy, tickling her erect clit with my middle finger in return.
“Mmm, mmm……♡ Slurp, suck, slurp, slurp, slurp♡”
My sister shivered at the surprise, then eagerly sucked my penis and especially the tip. The frantic movements around my rapidly pulsing glans sent shivers up my thighs.
“Your mouth feels so good on my dick…… ugh.”
“Chuuup, chuuup, chuuup, chuuup, bobbobobobobobobob♡ Fuaaa.”
When I praised her, my sister smiled happily and, instead of stopping, shook her head vigorously, taking my penis all the way down her throat and pulling it out repeatedly. Finally she pulled away. My penis, covered in her spit, throbbed and twitched in disappointment.
“Mmm, gulp……♡ I practiced a lot to suck you nicely at the time…….”
After swallowing the saliva in her mouth, my sister smiled with delight. Then she stood up in front of me where I was sitting on the bed.
“……Want to have sex again? This time I can move too?”
Schlick……♡
And she spread her own wet pussy, showing me her erect clit and her dripping vagina as she seductively invited me.
“You knew I wanted this the whole time and still didn’t meet me?”
“That’s not right. I didn’t meet you because I knew this would happen……♡”
I got even more excited seeing her pussy and fixed my wildly throbbing penis in position. My sister climbed on top of me and positioned my dick at her dripping entrance.
