Chapter 10: Devilish Twin Sister

I froze like a deer caught in the headlights, as if a damn snake was about to strike and bite me, but instead, it was just hissing to freak me out.

"Huh? Yui, ease up on the death grip in your hug. I'm getting suffocated here," I managed, tapping at her arm.

"Spill the beans, onii-chan. Did you get laid? Is that why you're MIA today? And if so, who's the lucky lady?"

What the hell was going on here?

"Hmm? I can smell not one but two women all over you. I see... Did you bang both Natsumi-san and Chinatsu-san? Is that what went down, onii-chan?"

I could practically feel the bloodlust radiating off her, swirling around the room. My heart rate shot through the roof. Chills slithered up my spine.

"Seriously, both of them can be such cockblocks."

"Yui, what the hell, what's—?"

I couldn't even finish my sentence before Yui lunged for the bag—the one that had those two condoms I used with Chinatsu and Natsumi.

"I smell something here, onii-chan. What's in this bag?"

"Eh, wait! Yui, don't you dare open that!"

She opened it anyway, and her eyes zeroed in on the used condoms, each holding a load of my semen.

The light in her eyes vanished instantly.

"Seems like you've been up to some naughty stuff out there, onii-chan." She released her grip on me so she could untie the condom. Then, she lifted it up, and the contained load of semen dripped down, only for her to catch it in her mouth.

"Y-Yui, what the hell are you doing?"

"Don't worry. This is practically my nightly snack, so I'm used to the taste," she said nonchalantly. After downing it, she wiped the semen from her lips with her finger, then proceeded to suck the finger clean. "Your stuff is actually pretty delicious."

I was utterly stunned. Did she seriously just mention that she's been downing semen every single night?

"Y-Yui, you can't mean..."

"It's not what you're jumping to conclusions about, onii-chan. I'm still holding onto my V-card, and I've got no intentions of handing it over to anyone. At least, not to anyone except you," she clarified. "And the only semen I've ever tasted is yours."

"How did you..."

"How did I manage it? Well, obviously by giving you some late-night blowjobs while you're sleeping."

Wait, she's been giving me blowjobs while I'm asleep?

"Y-Yui, wha-what the hell..."

"It's totally your fault, onii-chan. You've always been so sweet to me since we were kids. After okaa-san passed away, and otou-san took custody of me, you've showered me with warmth and affection."

Our parents got divorced when we were just three. Four years after that, we found out that okaa-san had died from an illness. Back then, I had no idea I had a sibling, let alone a twin sister. Tou-san took her in, and we started living under the same roof again.

"I've been craving you, longing for you, onii-chan. I've been head over heels for you all this time. But lately, there's been this swarm of freaks orbiting around you. So, I need to make sure I chain you down."

Chain me down? What the hell was she planning? Yui spun the chair I was sitting on, finally letting me lay eyes on my twin sister.

Framing her cute, beautiful face was a set of twin tails. Her name was Kurogane Yui. She had a reputation at her school as one of the princesses. Her aura wasn't quite goddess-level like Chinatsu and Natsumi, probably due to her breasts being slightly smaller than theirs. But honestly, if you lined them all up and asked me to compare, I wouldn't be able to tell much of a difference.

But let's move on...

Yui and I might be twins, but we were quite different when it came to each other. She was outgoing, gifted in both talent and beauty, and had impeccable manners. Because of this, she had fans not only at her own school but also in other schools (we attended different ones). Even with my familial bias, I'd say she's close to being the perfect girl... or at least, I think so.

"I'm going to milk you dry tonight until you can't even think of touching those sluts again!"

"Huh?!"

In the blink of an eye, my hands were bound behind my back. How the hell did that happen? Was she already tying me up while she was hugging me? I hadn't even noticed.

As I tried to process the situation, Yui abruptly dropped to her knees and began undoing my belt.

"Hold on a second! W-Wait!"

"Don't worry, onii-chan. I'm going to milk you so dry that those women won't even cross your mind again."

Without any hesitation, she yanked down my pants. My cock sprang free, smacking against Yui's cheek. But she didn't flinch in the slightest.

"Your dick is just as impressive and big as I remember, onii-chan. So, this cock has finally lost its virginity, huh? The thing I wanted the most, and it got taken by those two. But don't fret. I'm going to clean it up so well that it'll look like you're still untouched. Get ready." With that, she opened her mouth wide.

What the hell was going on here? Why was Yui doing this? I was utterly confused. Yet, despite my confusion, I couldn't deny the fact that my cock was rock hard. What was I even thinking? I already had two girlfriends... I couldn't betray them like this.

But my body wasn't listening to reason. It was clear that I was getting turned on by this situation. It meant I was at least considering the idea of going through with it with Yui.

I was at a loss. I didn't know what the fuck to do. Should I just go with it and not resist? But this was my sister, my blood sister, my twin sister, for fuck's sake.

I knew I should stop her. But even so, I didn't say a damn word. I just allowed her mouth to envelop my throbbing dick...

Then, out of nowhere, a knock came at the door.
