A Slip of the Tongue
Back when I didn't have a boyfriend, whenever I locked my bedroom door and muffled my own sounds while playing with myself, I noticed something. Every single video that suited my taste ended in a similar way. On the camera lens, the woman being treated roughly by the man would let out cries of pleasure. The man, well, since he was feeling good, would let out heavy, ragged breaths too. As their movements grew more and more intense—after he shoved in that thick, massive cock that made me think, "So a cock like that actually exists" the first time I saw it on screen—he would stop moving. Twitch. Twitch. Then, unlike the intensity from before, he would slowly, as if showing off, pull it out. ...Leaving behind the mark that he had completely conquered her. The final shot captured the woman, her face a mess of pleasure, her tongue lolling out, showing just how good it felt. There wasn't a single video that deviated from this obvious repertoire.
...Which is why.

They’re doing it without a condom? Ah, well... it’s a safe day, so I guess it’s fine? But you never know what might happen, shouldn't I stop them? But then again, Woojin is thrusting his hips so hard because he’s doing it... raw? Like Jiyoon said, doesn't that just mean doing it without a condom feels that much better? Come to think of it, I... haven't done it without a condom yet. So, should I stop them until I get to do it first? ...It’s already happened, so what’s the point of stopping them now? And could I even stop them if I tried? Both Jiyoon and Woojin were so aroused they wouldn't even hear me.
With a myriad of such thoughts, I only managed to part my lips. As a result, I stared at Woojin, who had semen dripping from the tip of his withdrawn cock, and Jiyoon, with the same thick fluid leaking from her entrance, from a distance where I could reach out and touch them. The fact that I was leaking slick, wet fluid between my own legs was probably because the scene I was watching right now was chillingly similar to the videos I enjoyed watching.
"..."
If I could, I’d want to pull Jiyoon’s cheeks this way and that, asking her why she did that, but my crotch was so soaked, as if I’d masturbated, that I couldn't say a word. If I tried to preach in this state, Jiyoon would just tease me, asking why I got wet watching them. She’d definitely provoke me by saying things like, "Does my sister have a cuckold fetish? Should I take more away from you?" How could I even bring it up? I was just wet like I always am because, if you ignore their faces and voices, it was just like watching a video that perfectly matched my tastes: a woman with a great body being ravished like a beast by a man with a great body and a huge cock, and being clearly marked with internal ejaculation. She wouldn't care about that.
If I had at least felt the fear of "What if Jiyoon gets pregnant?" like last time, I wouldn't have gotten this wet. If the situation in front of me hadn't looked so much like the videos I usually look for on my phone, I wouldn't have gotten this wet. Feeling my ears turn red with embarrassment, I quietly got up from my seat and grabbed some wet wipes before their eyes could turn toward me.
"...Take it easy. The kissing."
The wet wipes I used to clean my fingers after masturbating. I grabbed them from the drawer by the bed, and when their lips parted for a moment, I dove in between them and pushed firmly against Woojin’s chest. I was worried he might ignore me, but seeing him pull back obediently, it seemed his excitement had cooled down a bit thanks to the ejaculation. Of course, only his excitement had cooled; looking at his stiff, semen-covered cock, he didn't seem to have the slightest intention of ending it after just one round.
"Stop making weird noises...!"
"Then you shouldn't have done it inside in the first place... Haaaa..."
Having lived with Jiyoon, who has become much more talkative these past few days, I knew that if I responded to every little prank, it would never end, so I just ignored her. Since the amount of fluid, which seemed impossible to clean up with just one wipe, was soaking the bed sheets, I tore off two more generous sheets and wiped it clean. Then, I balled up the semen-smelling wipes and tossed them into the trash. ...It was a safe day anyway, so I didn't have to worry too much, and to get it all out properly, I’d have to scrape it out in the bathroom. So for now, I just wiped off what was visible.
"Woojin-ah. Hey..."
Instead of Jiyoon, who looked dazed from the lingering afterglow, I cautiously approached him, his breath still ragged. I mumbled, unable to even meet his eyes... and finally, feeling like, "Whatever happens, happens." I pushed Woojin, who was sitting, and knocked him over until he was half-lying down. Because I couldn't bring myself to talk about it. I couldn't bear to talk to Woojin about the internal ejaculation that had just happened, asking, "Did it really feel better doing it raw?"... If he even nodded, the atmosphere would turn into one where I’d have to do as much as Jiyoon. Even if I insisted that internal ejaculation was absolutely, positively forbidden, we’d at least have to do it without a condom, and if Woojin got too excited even after I begged him to pull out...
I would also, like that... "I'll... clean it... for you?"
So, somehow, I pulled the focus back to this embarrassing act, away from the internal ejaculation that Jiyoon had pushed to the forefront.
"...Tsk..."
...I’ve eaten Woojin’s semen plenty of times, so that didn't matter, but eating my younger sister’s vaginal fluid mixed in with it was a first. I thought he might like this, too, instead of just internal ejaculation. "Why are you doing it alone, sister? ...Move over." "...Phaha... ...There. Is that good?" I thought he might like having his younger sister and me sticking to his cock, cleaning it with our mouths. I let Jiyoon, who crawled over to me on all fours, take a spot, and I licked the glans without caring about my tongue touching it. ...Actually, licking the glans that I had already cleaned perfectly with my saliva together with my sister was closer to foreplay than cleaning.
"...Ah. It twitched..."
"Pfft... I can hear you even if you curse that quietly, you idiot. Anyway, right now, all I can hear is you sucking his cock."
"..."
"Why don't you just say
