Because My Boyfriend Likes It
Excitement is something anyone can experience. To begin with, the state of being "excited" doesn't stem from just one single emotion, which is why it’s so accessible. There’s the most common type of excitement that starts with "anger" and leads to a fistfight. There are cases where one gets worked up over a false accusation and pours out a torrent of self-defense. And isn't there sexual excitement, which usually leads to something erotic? There must be many others besides these. Regardless, since excitement is a state that anyone, regardless of age or gender, can experience at any time, there is almost no one who doesn't know what that "slightly broken filter in the brain" feels like when you're worked up.
That is why it is common to have the experience of doing something on impulse when excited in the past, only to have the results turn out poorly, leading you to look back later and regret it, thinking, "Ah, shit, why did I do that?"
*Slurp, shlick*—the taste of the rich semen that had touched her so intensely it splashed inside her mouth, not to mention the sensation of her younger sister’s soft tongue still vividly lingering on her own. Lee Hayoon was reeling. 'Crazy... crazy... cra... zy...' Far from feeling a sense of superiority by showing off her relationship with her boyfriend in front of her sister as originally planned, she was belatedly realizing that she had ended up doing something bizarre with her sister. She was currently replaying the actions they had committed on the bed three minutes ago.
'I really... touched it... ……Ugh….' To be precise, it was closer to embarrassment than regret.
Up until the point where I was having sex using Jiyoon as a cushion, there was nothing strange about it. Jiyoon, who was pinned beneath me, was clearly displeased, and I... well, it was so thrilling that I kept climaxing, and Woojin liked it a lot, too. I couldn't see inside his head, but that cock that was pounding deep into the back of my uterus—I can still feel for certain that it was more swollen than usual. But the problem is what happened after that. While Woojin was thrusting into me as if he were about to ejaculate any second, the moment Jiyoon started saying weird things from beneath me...
Was it because of that embarrassing question—asking whose pussy felt better, mine or Jiyoon's—that rolled out? And somehow, the word "fellatio" came out of Woojin's mouth? And then, dividing the territory so our tongues wouldn't touch while licking...? In the end, out of pride, we ended up licking each other's saliva...
*Slurp, shlick, shlick*—while my tongue was touching Jiyoon's, the white semen...
"…."
...Blegh. Ugh. Why did I do that? Lee Hayoon, you idiot!! This is all because I got more excited than I expected. The part where Jiyoon licked the cock with me at first—I was going to endure just that much because Woojin would like it. But she kept provoking me...! She was sucking on Seo Woojin's cock, which was covered in my saliva, without any hesitation as if she didn't care...! Rather than just watching Jiyoon perform fellatio, I felt like I had to do something...
When I came to my senses...
Jiyoon’s playful smile, which I’ve been seeing so often lately. As I avoid that awkward yet familiar, strange gaze and brush my cheek with the back of my hand, the warm heat is transmitted entirely. ...I feel like I’m going to die of embarrassment because I received his semen while half-kissing her earlier, so why is she so fine? Did you really intend to touch tongues with me just to suit Woojin’s tastes? You, who usually hates even dipping a spoon into the same pot as me?
Just as I was having dizzying delusions about how she could be so fine even though our tongues had touched, *tap*. I heard the same flicking sound I’d heard before. At the same time, I could see Jiyoon’s ear, which had been turned toward me while she was looking at Woojin. Her cheeks were only slightly flushed, but her ear was burning red as if she were dying of embarrassment. As expected. Jiyoon was just pretending to be okay on the outside. Well, from her perspective, she had swallowed semen while her tongue was touching her own sister’s, so how could she not be embarrassed? She’s just pretending to be fine because I’m being more openly embarrassed.
With that, I flush my cheeks hot again and step into the bathroom.
"…."
On one hand, maybe it’s because I noticed that Jiyoon is also currently very embarrassed? Looking back on what happened a moment ago in a state much calmer than when we were on the bed.... Ah, absolutely not. Absolutely, definitely not. It doesn't mean I liked that my tongue touched Jiyoon’s.
"…."
I thought I would gag immediately if I licked even Jiyoon’s saliva, let alone her tongue, but when I tried it by accident... It was disgusting, but not enough to make me gag. Not to the level of mixing tongues and kissing Jiyoon, but just the level of licking the cock together for Woojin... and maybe a little more embarrassing than that... I felt like I could endure it somehow. Even Woojin—when I thought about the amount of semen, the number of times he ejaculated, the intervals, and the thick consistency that remained unchanged until the last ejaculation... he liked having sex with me, but he seemed to really love seeing us two sisters tangled up like that.
Along with the memory of my tongue touching Jiyoon’s that I want to forget immediately, embarrassing thoughts that I never would have had yesterday are running through my head.
"…."
Like, maybe I should just yield one step today and try it Jiyoon’s way... Nauseating. Embarrassing. Humiliating thoughts. To use a metaphor that comes to mind right now, it’s like searching for "event Santa costumes for women" on the internet, suppressing the embarrassment because it’s almost Christmas. I don't have any desire to do things like that, and if I had to choose Yes or No, I’m definitely leaning toward No without any ambiguity... but sometimes, doing things like this makes my boyfriend happy. It feels like folding my pride, pressing the purchase button, and waiting for Christmas Eve. Because of that, my heart is quite unsettled right now.
It’s nice to feel a sense of superiority by being ravaged only by me in front of Jiyoon according to my tastes, but being ravaged and left a mess all night long while doing that... embarrassing thing... with Jiyoon according to Woojin’s tastes—it doesn’t feel as repulsive as when Jiyoon first suggested it yesterday. Just for today. No. Until the sun rises tomorrow, just for half a day...
"…."
Besides, looking at what Jiyoon is doing, even if the promised two weeks are over, she’ll probably pretend to have broken up with him in front of me while contacting Woojin like crazy behind my back. Like, "Unnie doesn't allow unprotected sex, right?"... seducing Woojin.... And then doing it a ton with Woojin, who eventually falls for the temptation, without me knowing.... If that’s going to happen, wouldn’t it be better to keep Jiyoon in a place where she’s clearly visible to me until she gets interested in another man...? Seriously.
I, who said firmly that I had no intention of leaving the two of you alone, snatched the showerhead and sprayed water at Jiyoon, inserting myself between the two. After spraying plenty of water on the mouth that had become dirty from swallowing a lot of semen with me, and around Jiyoon’s vulva, which was still wet with love juice... I rinsed my own mouth once, washing away the taste of semen that was stuck in my throat and the sensation of Jiyoon’s tongue, and then pointed the showerhead at Woojin, who was next to me.
"…."
"…."
...On his sweat-drenched body from how hard he must have moved, and on his lower abdomen that was still pounding my buttocks from thrusting to the root just a moment ago... I spray water to clean the cock, which was covered in my and Jiyoon’s saliva, even though it had shrunk in size a bit from losing some energy, but was still closer to being erect if I had to choose.
...Since it wouldn't be properly clean if I only washed it with water, Jiyoon, who had brushed back her dripping bangs once, while looking at the two of us from right beside me, wrapped her hand around the cock to make a ring. Slowly. Much slower than when I was giving him a handjob. Much slower than when Jiyoon was brushing over it while I was sucking on the glans just a moment ago. With the meaning of "I'm not doing anything erotic," I stroked it slowly.
I was flustered because he was making his cock stand up to the point where veins were popping out with just that slow hand movement... but it was still too embarrassing to make a joke like, "Are you turned on because Jiyoon and I are watching?". It was too embarrassing to say something like, "Shall we wash just this much and go back and… do it?", because it was obvious that Jiyoon, who was right next to me, would follow me to my room. Woojin wouldn't stop Jiyoon 100%, and I... in my current state of mind, for some reason, I didn't think I would stop Jiyoon either.
Unlike a moment ago when I only thought about washing him, I whisper in a low voice, stroking him with an ambiguous intensity—not explicitly, as if it were just washing him, but not quite enough to be called an erotic act. *Swish, swish.*
Instead of an honest answer that he wasn't satisfied, a silence that clearly showed his inner thoughts continued. And I, instead of taking that as an excuse to take him to the bedroom and have sex...
Bringing up the conversation I had whispered with Jiyoon, I tightened my hand around his cock once and pulled it down to the root. On top of my hand... near the glans, where it was visibly swollen and plump from just that... I let Jiyoon’s small hand touch it.
*Squish, squish, squish.* Spreading the pre-cum leaking from the glans onto the surface of the cock, which had become stiff from being washed with water, making it slick and wet, I said,
Instead of Seo Woojin, who was still avoiding the answer, I held his cock, which was stiffly erect like in the bedroom, with my fingers, and together with Jiyoon, who was already stroking near the glans until it made a wet sound, we gently licked his chest from both sides, one side each.
Spitting out the saliva I couldn't swallow while teasing him onto the stiffly erect cock, I felt my fingers get slickly wet with my saliva and the saliva Jiyoon spat out afterward. While I was bumping my hand against his lower abdomen...
The sigh that escaped his lips as he lightly hugged the back of my head was so stickily immersed in pleasure that I had never heard it when we were having sex just the two of us.
I, too—though I only realized it after I said it—command my younger sister with a sticky voice contaminated by sexual desire. I even used my own hand to press down on the back of Jiyoon’s head, who was nodding on her own while kneeling on the bathroom floor, meaning for her to swallow it deep so Woojin would like it. At the same time, I stood on my tiptoes slightly.
Sharing sweet saliva with Seo Woojin, who still seemed to think that telling the truth would be a big deal and was trying to hide it, until Jiyoon’s mouth, which was in the middle of fellatio, was filled with semen so thick it clumped into lumps.
Until she eventually couldn't swallow it all and coughed, coughed, and spat it out, just like me a moment ago!
...After a sweet kiss continued for a long time, I swallowed the cock covered in the dirty saliva Jiyoon had just spat out deep inside. After a few more ejaculations, I spat the semen piled up on my tongue into the mouth of Jiyoon, who was kneeling beside me. ...Ah, of course, I absolutely didn't want to do this, but Jiyoon had already opened her mouth and stuck out her tongue, asking me to spit it gently here.
And, this appearance of the two of us. Because my boyfriend will like it. Even though the showerhead, which wasn't hung on the wall properly, fell with a clatter, my boyfriend, who was so excited that his erection hadn't died at all, had his usual kind appearance nowhere to be found. He grabbed our two sisters' wrists with one hand and dragged us two people out of the bathroom and into my bedroom, which hadn't even been fully ventilated yet. ...Because he likes it that much.
