Chapter 7: Sister's Outing
The next day.
Sunday.
Today was the day I had promised to go shopping at the department store with my little sister, and since there's a movie theater on the 8th floor, we decided to watch a movie together if we had time. Plus, if we eat and have a coffee at a cafe, it would probably be afternoon when we returned.
"Sigh. The weather is scorching..."
It's mid-August, when the heat is the worst, and the news is warning about heatwaves. I wanted to wear a short-sleeve t-shirt and shorts, but since it's a date with my cute little sister alone, I decide to be a bit careful.
So I choose the clothes I like and check my phone.
A KakaoTalk from Ha Yeon.
"If you're ready, come down to the 1st floor, oppa."
"Yeah, I'm coming now."
After sending the message, I head straight to the 1st floor.
There, Ha Yeon, who was waiting for me in the living room, sees my KakaoTalk and immediately spots me coming down the stairs and waves.
"Oppa. I'm ready?"
"Yeah. Sorry... I made you wait a lot?"
"No? Not really?"
She shakes her head and walks towards me. Her fashion is carefully chosen, making her look even prettier and fresher today. My gaze is involuntarily fixed on her.
"How is it, oppa?"
Did she sense my gaze? With a confident expression, she turns around once in a bright pose like a princess in a cartoon.
Her long hair sways, and the fragrant shampoo scent reaches my nose.
Ha Yeon's fashion is a summer coord with exposed white limbs, not overly revealing, and doesn't show body curves much, but that actually emphasizes her cute appearance. The point is her white neck, slightly visible between her long hair because she doesn't get much sun.
If her little sister is inherently cute, even if she wears newspaper, her outfit would be perfect, but wearing such a refreshing outfit makes her a perfect idol-like girl.
In conclusion.
Just cute and pretty.
But there's one suspicious point: even in this hot summer, Ha Yeon is wearing stockings on her legs.
Of course, they're thin flesh-colored stockings, but with sneakers, it doesn't look very breathable.
"By the way, Ha Yeon, is it okay to wear stockings? The weather is really hot today. What if sweat gets in the stockings while walking?"
It takes about 20 minutes to walk to the department store, and even after arriving at the department store in this scorching heat, I'd have to walk around all day for shopping, so stockings might be uncomfortable.
'...Later, sweat between my toes would be really gross.'
But Ha Yeon just smiles mysteriously.
She doesn't seem to intend to take off the stockings.
"It's fine, oppa. I thought about it."
"Whatever you want."
Even if sweat gets on her little sister's feet, I can clean it. Since I'm also in charge of Ha Yeon's slippers, in this hot summer, my advantage is cleaning every corner of her body so she doesn't feel gross.
Especially on days like today when heatwave warnings are issued, I need to wait by her side so I can clean her armpits, toes, and between her buttocks where sweat accumulates, even if I just walk a little.
"Let's go now, oppa."
"Wait a minute."
I understand my little sister's excitement for a date after a long time... but there's still a lot to check before heading to the department store.
"Did you do the enema?"
"Yeah. I did a really thorough one and washed it two or three times? Want me to let you check it yourself, oppa?"
"Let's do that. It's good to get an anal check before going to the department store."
One of the courses included in outings with my little sister is sex. At least three times, and given Ha Yeon's preferences, she might use an enema.
Plus, because I prepared for the early outing this morning, I haven't given her the little sister anal kiss as part of the morning routine.
It might be troublesome, but before the outing, I need to inspect Ha Yeon's anus. And behind that, there's a small personal desire to see my little sister's pretty anus...
"Yeah. Okay."
Fortunately, Ha Yeon immediately took off her pants and panties without complaint and presented her naked buttocks towards me.
Her cute, small, round buttocks and smooth skin. White flesh and the pretty legs extending down. On her knees, the stockings and panties half-removed... showing her hairless pussy slightly while half-undressed is incredibly cute.
In that state, Ha Yeon puts her hands on the desk and extends her buttocks to give the optimal position to show her anus.
"Like this?"
"Yeah. Good job."
To show appreciation, I pat her buttocks. Thanks to Ha Yeon's active cooperation in the anal inspection, I just needed to grab and spread the soft buttocks in front of me.
I squeeze the firm buttocks in my hand as if I won't get tired of touching them all day, and spread them to the side, opening the gap between the buttocks like soft bread, exposing the secret anus.
My cute little sister's anus.
Tasty pink anus.
'...Ugh. Can't hold back...'
Feeling ecstatic, I observe the fully exposed anus of my little sister with my eyes.
Did she sense my gaze? Ha Yeon laughs lightly and, as if it's service, squeezes her sphincter muscle to twitch her anus openly. Then, reversing the force, she slightly opens the cute wrinkles, and each time, her anus spreads wide, showing the clean pink inside wriggling through the gap.
"How is it? Clean?"
"Yeah. As expected, clean..."
The clear, pretty light on the anus entrance and the cute wrinkles around it. Ha Yeon shows her anus twitching as if repeating contraction and relaxation. I forget my original purpose and slowly bring my nose close.
'Just a little... smell it...'
Intense impulse dominating my mind.
Since I need to smell the scent for the anal inspection anyway, I slowly press my nose between the buttocks and sniff.
'Good scent...'
Clean soap scent. The fact that her little sister's anus is clean is already proven by just the fragrance. But I can't say I've sufficiently confirmed her anus just by smelling it.
To draw a definite conclusion that her little sister's anus is clean, I need to carefully inspect a bit deeper, so I cover the twitching anus with my lips.
"Yeah.... Checking inside too?"
Ha Yeon, feeling my lips close to the anus wrinkles, lets out a soft breath and slightly lifts her heels to adjust the buttocks angle.
"Wait, oppa. I'll relax my buttocks. Uhn...."
Twitch♡ Her sphincter muscle, repeating contraction and relaxation, gradually loosens, ready to softly swallow my tongue anytime.
I also cover the anus wrinkles with my lips and suck strongly a bit, making Ha Yeon's cute anus slightly pull up.
"Chuuup... chuuup.. chuuuyuuup...."
The pulled-up anus wrinkles stick to my lips as I lick her anus. After inserting the tongue tip into the anus, I slightly bend it to gently scratch the mucous membrane near the anus entrance to relax it.
Ha Yeon's buttocks naturally contract to push out any foreign substance entering from inside, pressing my tongue firmly, but eventually my persistent attack opens the entrance.
The natural stimulation from this process feels quite good, so Ha Yeon's pussy drips clear, transparent love juice onto her thighs with a slurp♡.
Knowing Ha Yeon's anus quite well, I know that bending the tongue to press the entrance mucous membrane makes her very happy.
'With this, I'm a super good oppa, right?'
Feeling that pride inside, I slowly insert my tongue deeper into the anus.
"Uhn.. huh.... Check the deeper part too..."
With a voice trying to hold back laughter, Ha Yeon requests. Meanwhile, my tongue digs deeper into the anus, gently stirring even the deeper places that shouldn't be touched even in sibling intimacy.
Of course, I know her inside is very clean, so I can freely insert my tongue.
Thanks to the diligent licking, Ha Yeon's anus becomes moist. With some saliva, bending the tongue to press inside makes the cute wrinkles open with a slurp♡ and lewd sounds. After stirring the inside of the buttocks, Ha Yeon's smooth thighs tremble.
"Yeah...."
Ha Yeon's cute rebellion.
The one who was slightly lifting her heels to adjust the buttocks angle suddenly laughs as if she had a funny thought.
"Yap!"
At that moment, Ha Yeon's anus, which had swallowed more than half of my tongue, suddenly contracts strongly, closing the flower-like wrinkles.
"Ek..!!"
Surprised by the sudden squeezing of my tongue by the little sister, I shout, and Ha Yeon laughs lightly and relaxes the sphincter again.
"Just kidding, oppa. How's the inside of my anus?"
I try to pull my tongue out instead of answering.
When trying to pull the tongue out of the little sister's anus, each wrinkle sticks stickily to my tongue, pleading not to pull out. Just before the tongue comes out, the anus wrinkles pull up to cling to my tongue.
Then, once the tongue is out, it contracts again, closing the flower petals cutely as if nothing happened.
"Yeah. Really clean."
After wiping the saliva and love juice on Ha Yeon's buttocks and thighs, I put her clothes back on and stroke her crown. Ha Yeon, who obediently let me touch her hair and smiled, finally reveals her cute teeth and laughs.
"Then shall we go?"
"Yeah."
"Yeah. Let's hurry!"
Looking at Ha Yeon, who seems more tense today, I have a bad feeling that today will be quite busy.
