My little sister is a pervert.
This was not a revelation, it was a matter of fact. What truly made this repetition necessary was the 'extent' of perversion that my lil' sister had going on as of late.
I thought her depravity had a single target: me. Not that she would drag others into this.
Especially a girl younger than her. To Sagiri's credit, Hana didn't appear too shocked of what occurred.
The mere idea she went on to give me her first BJ before those lips had ever delivered a kiss to a boy made the entire thing even more scandalous.
Also, there was the matter of Sagiri being unabashedly proud of what just occurred. Hana was clearly more mature for her age, but the way she just followed Sagiri's advice despite the depravity of it all was shocking to say the least.
"Y-You sure you are alright?"
The girl nodded again. "Yes. Niisan's milk was yummy~."
Curse you, Hentai Logic!
The worst part of it all was also how easily Sagiri had Hana promise us both that she wasn't to tell her mommy about it. Which pretty much made this crime impossible to be discovered unless any of us three blurted the truth out.
I wasn't planning to do so, neither was Sagiri. Our motivations diverged, but where I feared the legality of the matter, my step-sister wanted this to become a thing.
"A huge harem for Oniisan!"
This huge proclamation came after we had gone through bathroom time and had breakfast readied up.
"...Of loli?"
"Nah, also Milfs, pervs, maybe some cute kuuderes and... hm," The girl turned to me with inquisitive eyes. "Do you like traps?"
"Nope."
"Okay, then all girls that can keep up."
"More?" Hana asked, appearing giddy all so suddenly - a reaction that had Sagiri smirking with pride, as if she was truly happy of having corrupted a child.
"Oh, you want more, Hana-chan?" Sagiri turned to me with her puppy eyes. "How about you gave her a 'lucky kiss' before we leave for school? Like you used to do with me?"
...I thought Sagiri would have forgotten about that habit of hers that I had slowly phased out since she was too big for that to work now and-
"What's a lucky kiss, Oniisan?"
I swear I could see throbbing hearts in loli's eyes, and I found myself sighing as I found myself cornered.
Taking the duo to the living room, Sagiri had one of the oddest 'aroused' look I had seen on her face just yet.
Meanwhile Hana appeared particularly nervous as she was quite upside down. Her ass was now presented to me while her head was looking upward as it rested by a pillow I set between my legs.
Her white pantyhose was rolled up to reveal that... she wasn't wearing any panties.
The more I interacted with this girl, the more I realized this one may be far more perverted than I had imagined.
Still, my gaze was stolen by her prized purity, the fattest mons, the plumpest cunny I had ever seen.
"Hehe, I knew you would have loved that one. She looks just so yummy. Right?"
"H-Hana-chan is... yummy, niichan~?" Hana half-moaned, desire to be tended to evident in her eager tone.
I licked my lips, deciding to give it a taste before making a call. Her tender slit easily allowed my tongue inside- the tip at least. The way she was so tight around my tongue was inside, but the warmth and the wetness had my heart drumming in shame and delight at once.
What a naughty child- no, a perverted loli.
Dark-blue eyes fluttered with bliss as a cute moan parted away from Hana's lips. The girl was definitely unprepared for cunnilingus, but the way she was reacting to all of this was positive.
She was totally smitten to have her sweet cunny lapped over. To make things more interesting, Sagiri didn't stood by the side this time around. Her skirt and panties had vanished to accommodate her fingers, but the girl had wanted more.
Her mouth joined mine in feasting upon Hana's flower, with her lips suckling at her immature clit, further stimulating the slutty loli.
Not even a moment of this addition that Hana had instinctively reached upward for Sagiri's own pussy.
Truly a threesome for a foreplay, and one that had the two girls servicing each other in no time.
That being said, Hana was truly the MVP of this 'game'. She squirted intensely for her first orgasm yet, hosing me and Sagiri both with a strong orgasm and then falling limp all over us.
Sagiri giggled, and yet her smile vanished as I had a very serious look on her face.
"And now we have to clean up the floor."
Her entry had meant a wider space for the wetting, which meant that some of the carpet was now stained in her juices.
Huffing as she fetched a mop and went to clean up her mess, I helped Hana with a towel, the girl spent up a bit as I fixed her up for the day. I had to carry her to school on my back but... at least she was truly 'drained' of any horny energy.
I knew Sagiri was as she loathed doing much in cleaning the house, and the mop was one of the worst chores she had to face from time to time.
Out of the house and on our way to our respective schools, I first dropped off Sagiri and then I moved to get Hana to hers. To my relief, the loli was back to her feet by the time we reached her destination, and she had a most angelic and innocent smile on her face as I dropped her off.
Today, I hoped, would be a most sane day beyond what had just occurred.
It didn't come to mind that Hana-chan was meant to be the 'tamest' of her friends when it came to kinky shit and...
While Hana was a reliable oath-keeper, she hadn't promised to keep hush-hush with her two close friends.
"Waah, you got a Oneesan and Oniisan?!"
Hoshina Hinata was loud. This much Shirosaki Hana knew from the first day they had been friends.
"Yes."
"Woah, how are they like?"
Himesaki Noa was similarly chirpy, but Hana was fine with both - especially since they were on their lonesome and they had given her candy to soothe her ears.
"They are nice."
"Wha? Just nice? Like, how is it to have a Niisan? What about your new Neesan? Is she like Mya-nee?"
The mere mention of that creepy young woman had Hana shudder and she shook her head. "N-No, Sagiri-nee is... cooler."
"No way! Mya-nee can be cool too. At times."
Despite how protective Hinata was of her sister, the little pinkette had her limits. Hoshino Miyako was a college student and... a bit of a creep. Especially since she wanted Hana to wear 'cute outfits' and take pictures of hers.
At the very least, Sagiri-nee offered and never pushed her to it and... the clothes Sagiri-nee had were actually cute and not creepy.
"Still, what about your niisan?" Noa quipped, sounding more interested in that. Maybe it was because she had some 'neesan' experience around Mya-nee, and Hana's Niisan was now her first Niisan experience.
"He is also cool. And handsome. And his milk is yummy."
...
"M-Milk? Boys don't make milk, silly Hana-chan."
Hana frowned. "He did. From his penis. It was the yummiest milk."
...
"R-Really! Boys do that?!" Hinata was flabbergasted and giddy.
"Woah! I didn't know that- but wait, did you really try it?"
"Yup. Just this morning."
"Oh- can we visit?! Now I wanna try and-"
"No," Hana quipped, stopping Hinata before she could finish the request. "It's a secret."
"Wha- but you told us!"
"Yeah."
"Well, that's because... you're my friends. But still, I need to ask niisan and neesan's permission first. Plus, wouldn't your parents be upset if you visited a stranger's home without asking first?"
Hana's quick thinking had the two other girls to stare at one another.
"Yeah, mama would be angry."
"Same. Mom and dad would give me a lecture but... can you ask? Then we can have hang out with them too! Like with Mya-nee-"
"Better than Mya-nee," Hana interjected, causing Hinata to pout.
"H-Hey, she is not that bad."
Silly Hinata, her and her sisterly love. Of course she couldn't understand how good of step-siblings Masamune and Sagiri truly were.
If she could, Hana would live with them permanently but... mama would be sad. So no.
Sad.
AN
Sagiri? Perverted Step-Sis with a Plan.
Hana? Slutty Step-Loli with Desire.
Masamune? He wants to write, but the fucks are good.
Next time? Hana learns more about her new 'siblings' and their games.
