Chapter 4: Sister and Anal Sex
Hayeon was in the cat pose, arching her chest and waist deeply while raising her hips high. From behind, her white and slender back, along with the cute rear view created by her small and round buttocks, was particularly pleasing to my eyes.
Especially, I saw Hayeon’s pretty anus twitching between her raised hips as if begging to be fucked, and recalling the responsibility to make my little sister feel good, I pushed my swollen glans into her anus.
“I’m putting it in.”
“Ah.... Yeah... It’s coming in....”
Hayeon’s anus, which had been loosened beforehand, was in perfect condition for anal sex.
As I pressed my glans close and pushed it in, the small, cute wrinkles around her anus opened with a 'tzrup' sound, sucking my glans into its sticky warmth. From behind, the pretty anus of my sister was wriggling as if wanting to be eaten right away, seductively luring my cock, and the sight was vividly clear.
“Is it not painful?”
“Yeah. I’m fine. It’s you who might suddenly cum, right?”
“Shit. There’s no way that happens.”
I pushed my cock, much tighter than her pussy, into the narrow hole of my sister, stretching the inside of her anus that gripped it tightly....
Hayeon’s small body had an enormous contraction power. How do I describe this feeling? The feeling of filling my little sister’s anus with my cock was really... one of the greatest happinesses I, as the older brother, could feel?
At that moment, Hayeon’s anus, which had been repeating contraction and relaxation, grabbed my glans tightly in her narrow hole and squeezed it hard.
“Ugh...! What are you doing...!!”
When I let out a moan from the tight pressure, Hayeon laughed 'fuf', moved her hips, and twisted my cock tightly. During this process, naturally, Hayeon’s narrow anus gradually loosened its strength and began to accept my cock, and I also regained some composure.
“Don’t... don’t play around like that.... I almost came.”
“Yeah. Sorry.”
I was momentarily startled, but my heart melted quickly at my sister’s lovely apology.
Meanwhile, my cock had penetrated deep into my sister’s insides. It’s surprising that with such a small body, she can take my entire thing.
“Yeah... Oppa... Stay still like that...”
“Got it.”
I filled my sister’s anus inside completely with my cock, and instead of moving, I decided to wait a little while until her narrow hole accepted my cock.
“Haa....”
Hayeon let out a soft sigh, still maintaining the cat pose and breathing deeply.
With my cock swallowed by her hips.
“Ugh.....”
If I stayed still, all sensations would concentrate on my cock, allowing me to feel the changes happening inside my sister more vividly. The feeling of her hot inner walls twitching and contracting, or the squeezing that sometimes strongly contracted and pinched my cock.... And the hot temperature that seemed to melt my cock.
It was all the process of Hayeon’s anus accepting my cock, but from my perspective, receiving that feeling vividly, I really wanted to move and was dying to.
“Should I move?”
“Wait a little. Oppa. I’m preparing right now.”
“Ugh.....”
As if to quietly do it, Hayeon’s coercion with her heels tapping my balls made me have no choice but to shut my mouth. That's why I said I don't like anal sex... but the tightness is so strong that it's hard to hold back...
“Oppa. Today, you have to cum at least twice, right?”
“I know. Damn. I’ll make you feel good.”
With the determination to fulfill my role as an older brother, I tensed my waist and held on. As a result, my bloodshot cock became even harder and firmly took its place inside my sister’s insides.
“Huuu.....”
Hayeon let out a satisfied sigh, resting her chin on the pillow and smiling. As if wanting to enjoy this leisurely moment a little longer, the girl who had been relaxing her anus finally gave permission.
“Now, you can move.”
“Yeah.”
Slowly pulling my waist back, I felt that my cock had adapted much more smoothly than before.
Of course, from the entrance, each wrinkle sticking sticky to my entire cock was the same, but it seemed that the untidy ejaculation incident wouldn't happen.
The sight of my cock slowly emerging from between her hips with a 'tzub' lewd sound and then poking inside again.
“Yeah... Ugh....♡ Oppa, a little faster...♡”
“Okay.”
Responding to my sister’s lovely request, I moved my waist faster. As the movement became more intense, Hayeon raised her hips higher to accept my cock deeper, adjusting her posture. In return, I poked my glans deeper, and cute wrinkles appeared on the sole of Hayeon’s foot.
“Ugh...! Yeah... It’s deep....”
“You like this, don’t you. Stabbing deep.”
I already knew her weakness or preferences through many anal sex sessions. Especially, when I stabbed her anus roughly, Hayeon would soon let out a sweet sigh 'Haa...♡'
“Haa.... Haa....”
Normally, I would think her anal hole is dirty and filthy, but with my sister’s hole, I don't feel any dirtiness at all. Moreover, since Hayeon has a clean and neat personality, she always does enemas before anal sex, so there's no particular disgust. Sometimes I help with enemas, but... well, it's very rarely.
Anyway, when I stabbed her pink-tinged clean inner walls vigorously, soon Hayeon, who had been burying her face in the pillow, opened her mouth.
“Yeah... Ahugh... That feels good....”
“Hey. Don’t get the pillow wet with saliva.... I’ll get scolded by mom later.”
“If I say I had sex with Oppa, mom will forgive me, right...? Yeah...♡ Aha.”
From behind, my sister’s pretty pussy, dripping sticky juice like a well-matured peach, was visible, and her clear transparent fluids were flowing down her thighs, dirtying the entire bed.
I worry that I’ll get scolded by mom later.
...Well, for now, let’s focus on stabbing my sister’s anus.
“Haa... Ugh.....”
Every time I scratched the inside of her anus with my swollen glans, Hayeon’s hips trembled. Before long, the atmosphere in the room was hot and sticky.
“Haa.. I’m going crazy for real...”
I had been slapping my sister’s small round buttocks roughly, and I felt the approaching climax like an explosion, slowly but surely.
“Ugh... Hey, don’t you think you should relax your hips?”
Instead of answering, Hayeon contracted her sphincter and squeezed my cock.
Ugh, this girl...!
“Oppa. Are you about to cum already?”
Hayeon looked at me with eyes full of mischief and tapped my balls with her smooth heel.
“Ah, no...!”
One of the most important rules when having anal sex with my sister. Until my sister reaches her climax, I must never cum. I didn’t want to lose my pride as an older brother, so I endured cumming as much as possible and continued to roughly poke her anus.
To ignore the pleasure felt from my cock, I focused my senses as much as possible on other things.
For example, vision....
“Yeah.... Haa....”
If I think about vision, naturally it enters my eyes from Hayeon’s face.
The girl resting her chin on the pillow, letting out a feminine soft sigh. A perfect sister who studies well and listens well to parents, and moreover, her face is pretty, so she’s always praised around.
She always received awards like model student at school, and she even managed to be first in the whole school once, so her grades are excellent.
'...Not helpful at all.'
I tried to delay cumming by thinking as much as possible about other things, but instead, just the fact that I was having anal sex with this perfect sister made me happy and overwhelmed with the desire to cum immediately.
“Oppa. Do you want to cum?”
As if sensing the pre-cum from the throbbing cock, Hayeon turned her head back and asked me that way.
“Yeah….”
“Yeah. I think I’ll go soon too....”
As if teasing me, Hayeon’s foot rubbing my thigh gently with her sole made my waist tremble. Moreover, her pink anus kept sucking my cock as if wanting to be fucked, how could I hold it....
Pang pang pang pang..!
I slapped her plump buttocks hard, and with the determination to send my sister away, I filled her insides tightly.
“Ugh....”
Suddenly, my rough movement made Hayeon bury her face in the pillow and let out a moan.
“Yeah. Ugh... Oppa. I’m cumming... Yeah...♡”
“Hayeon.. I think I’m about to cum too..!”
“Yeah. As deep as possible when I cum... right?”
I nodded, and according to her request, I pushed my cock as deep as possible, then relaxed my waist and started cumming.
Burrururit....!!
Suddenly, my vision turned white, and I ejaculated a large amount of semen into my sister’s anus. I didn’t see the ejaculation scene, but the intense cumming was so much that her small buttocks trembled.
I was pouring semen into her narrow hole as if filling it tightly. When my swollen cock blocked her anus inside tightly, Hayeon let out a 'ng' happy moan.
“Ah, Oppa’s semen... It’s so hot...♡”
With a voice full of excitement, her thighs trembled, and she ejaculated fluids. Hayeon’s anus, which had reached climax, strongly contracted and squeezed my cock, demanding semen. Finally, after cumming until filling her anus tightly, Hayeon relaxed her anus and let go of her strength with a satisfied look.
“Haa... Haa....”
“You did well, Oppa.”
My sister smiling while showing her cute teeth.
...Seeing it like this, I think the older brother role is really tough.
I have to make my little sister feel good by fucking her anus or pussy every day... Moreover, sometimes when we go out together, because she keeps requesting in the bathroom several times, I have to fill her pussy inside with thick semen.
How does such sexual desire come out from that small body... It’s really a mystery.
“Oppa. Do you remember the promise to go shopping together tomorrow?”
“Yeah, yeah....”
Eh. Tomorrow I’ll be squeezed hard again....
Thinking that, I let out a small sigh inside.
“Wait for it. I’ll really fuck you all day tomorrow....”
Listening to my sister’s inner monologue full of happy colors, I pulled my cock out from her sticky anus hole.
