That's right. The girl before me was my biological sister, Loxi Iblis—unquestionably a "loli." Like me, she had silver hair and red eyes, with noble royal blood flowing through her. Don't let her frail appearance fool you; her mastery in certain fields of magic was actually deeper than mine.
At the same time, she was my primary consort—my first wife. This was why I hadn't let her have sex with anyone else yet. As both my sister and my wife, I had to save her for last to slowly enjoy the ultimate pleasure of her being "taken."
As for why I married my sister? Simple. To ensure the purity of the royal bloodline, marriage between siblings is perfectly normal. The reproductive history of our clan could be described as a history of incest; each generation must produce a pair of siblings to ensure the lineage isn't polluted by outsiders.
"You wake up in the afternoon every day. Can't you go to bed earlier?"
I looked at her helplessly. She was becoming a total night owl. Recently, she'd been staying up until 2:00 or 3:00 AM because I had created a "game console" out of boredom. I used magic runes to construct a system engraved on mana-conductive stones—basically using Earth's logic for CPUs, encoding, and instruction sets. Currently, it could only play simple games like Sokoban or racing.
However, for a sister living in another world, this was already something revolutionary.
"Hmph, what's it to you?"
As she spoke, she pulled off her nightgown and stretched. Her youthful loli body was displayed before me: a slender waist you could wrap your hands around, a pair of small, budding breasts exposed to the air with snow-white flesh, and pink, cute nipples like cherries on a pudding. It was enough to make any lolicon lose their mind.
But I had seen my sister naked more times than I could count. I even knew exactly how many fingers her tender entrance could take.
"Alright, get up. I have to come wake you every single time."
I had tried to have the maids wake her, but she insisted that she would only get up if her brother came personally. Otherwise, she refused to leave the bed. So, I had to personally wake this night owl every day.
"Isn't that what brothers are for?"
She reached out her pristine, flawless feet toward my mouth. Her cute, white toes wiggled as she looked at me with a playful, teasing gaze.
"Brother, where's my morning kiss?"
I knew what she meant. I reached out, held her small, white foot, and kissed the smooth arch.
Sometimes my sister really showed she was my sister; her demonic nature manifested mostly in her desire to tease me. No one would ever guess that the famous Demon Lord of the Demon Realm had to kiss his sister's little feet every morning.
Satisfied, she nodded and opened her porcelain-white arms to hug me. Her cherry lips met mine; her tongue pried open my teeth, tangling with mine and sucking on my saliva with lewd, wet sounds. After a long kiss, she pulled away, her eyes narrowed beautifully.
"That was my morning kiss for Brother ♡"
Even though we were married and she was my wife, she still preferred to call me "Brother."
"Are we done? I need to go see the others," I said.
"Wait a second."
Loxi reached down to her crotch and pulled off her thin, white panties. She stuffed them into my hand, and I could clearly feel her lingering body heat.
"There. These panties are a gift for Brother. Take them and use them to jerk off." She covered her mouth with her hand, letting out a light, bell-like giggle.
I walked out of the luxurious bedroom holding her panties, shaking my head helplessly. She loved teasing me. Does the Demon Lord really need his sister's panties to masturbate?
Still, I brought them to my nose and took a sniff. Hmm... the familiar jasmine scent of my sister, mixed with the slight lewd aroma of a girl's private area. Very nice.
Reaching the corner, I casually tossed the panties to a male guard on duty.
"Loxi just wore these. Take them and jerk off. Make sure you finish on them, understood?"
His gaze was resolute. He gave me a perfect military salute and shouted with conviction:
"Yes! Lord Demon Lord! I guarantee the completion of your order!"
He solemnly and carefully tucked the panties into his breast pocket and returned to standing perfectly still, guarding the floor.
"Good. Keep it up. Maybe you'll be the next captain of the guard."
I patted his shoulder. Amidst his gaze of drive and longing, I walked to the second bedroom door.
I opened it. Hmm, not here after all.
It was normal. Not everyone slept in late like my sister. This was Dreamy's room, my second wife. Her race was the Dream-Eater, masters of weaving dreams and high-level illusions. Compared to Loxi, Dreamy often acted more like the primary wife, handling the harem's daily affairs. She was gentle and well-respected by everyone.
Probably busy with something else, I thought as I moved to the nxext room. I didn't even have to look to know Yeli was inside; she rarely left the room during the day.
I pulled open the door. The curtains were drawn, and the room was pitch black—so dark you couldn't see your hand in front of your face. The atmosphere was eerie.
"Hey, Yeli, what gives? At least have some light."
I cast a light spell. The room was decorated in black and red tones. There was a mirror on the table next to a vase with blood-red flowers. The walls were covered in strange symbols and magic circles—it looked less like a girl's bedroom and more like an alchemy lab.
I closed the door and looked around, but she was nowhere to be seen.
Suddenly, a pair of slender arms wrapped around my neck from behind. Just as I was about to turn my head, I felt a sharp pain in my neck. A girl with pure golden hair had opened her red lips to reveal two sharp silver fangs, biting into my neck. Her throat moved up and down as she gulped down my blood.
After a while, she let go and opened her dazzling deep-blue eyes. Her gaze was seductive and mysterious as her tongue licked the remaining liquid from her lips.
"Huhu... Mortal, I am most satisfied with your offering. What reward do you seek?"
I raised an eyebrow and grabbed her ear. "Didn't I tell you not to speak like that?"
"Ow, ow, ow! Ugh... damn it, I am a noble member of the Blood Race! How can you treat me like this?"
Yeli blinked her large eyes with a look of grievance. This was my third wife—a vampire, or more accurately, a member of the Blood Race. "Vampires" are merely low-level demons converted after being bitten; they can't handle sunlight and fear silver or garlic. High-level Blood Race members aren't really harmed by those things, but Yeli just preferred the dark. They also don't need blood to survive and can eat normal food.
However, Yeli loved drinking my blood. Every few days, she'd clamor for it. Usually, she bit my neck, though once she had the "bright idea" to bite my 〇〇, for which I gave her a sound thrashing. Since I had royal blood, I wouldn't be turned into a vampire by her bite.
"Alright, stop keeping the room so dark. You're not a low-level vampire." I walked to the window and pulled back the black curtains, letting the afternoon sun spill in.
"Ugh... I still hate it..." Yeli squinted and hid behind my back, looking pouting.
"Also, go out more during the day. Go play with Loxi if you have nothing to do. You two get along, don't you?"
"Loxi is obsessed with that 'game console' you made. She doesn't play with me anymore..." She pressed her head against my back and hugged my waist, looking pathetic.
So that was the reason?
"Fine, next time I'll make a version for two players so you can play together."
Yeli nodded happily, showing her two sharp white fangs. I patted her head and gave her a kiss. Hmm, tastes a bit bloody... definitely shouldn't kiss her right after she feeds.
Yeli gave me a dissatisfied look, then looped her arms around my neck, refusing to let me pull away. Her tongue pried into my mouth to tangle with mine, exchanging saliva before she swallowed it. After a long time, she let go, her eyes burning with a fire I recognized as arousal.
"Hey, we haven't done it in a long time, have we?" she said resentfully.
"Ahem, well, I've been busy with affairs lately." I lied awkwardly. In truth, I was just being a lazy husband. With so many women, even the Demon Lord can't be everywhere at once.
"Can't we do it now?" She stared at me with her sapphire-blue eyes.
"I have something soon. How about... I find someone else for you?"
"Forget it. Today I only want you. Remember me for next time..." Yeli leaned back in and bit my neck gently...
