I Have The Only Ero Knowledge In The World Chapter 4

Experimenting on my sister to make her an onahole - 2

I extended my hand and touched her breasts

I rubbed it, but I didn't feel soft as her boobs are too small

"How?"

I looked at Rina's expression, but there was neither embarrassment nor pleasure on her face

Are her breasts not sensitive enough?

Then, how about a nipple?

A small protrusion is on each of her boobs

The color is also lightly pink

Let's try to pinch it with my fingers

"Fuh!!!"

Her appearance changed as I pinched her right nipple

I continued to slightly pinch and kneed her nipple

She shakes her body as a voice leaks out of her mouth

"It feels strange somehow….."

Even though she doesn't have any knowledge about sex, her nipples are still functioning as an erogenous zone

After confirming this I pinched both of her nipples at once

"Hey, aaa."

Voices leak out from her lips

Rina leaned on my body as I twisted her nipple gently

"It's pleasant"

Rina doesn't even try to hide her voice

I don’t know if its embarrassment or pleasure

While hearing the obscene sounds coming out of her small parted lips, I wanted to kiss them

But my reason held me back

Is it okay? My first kiss will be my sister?

"Rina, do you have a boyfriend?"

Not knowing what to do, I asked her

Shocked by my sudden question Rina doesn't know what to say, also as she was lost in the pleasure of her nipples she couldn't properly answer

"So, do you have a boyfriend?"

"You mean a relationship?"

"Yes, are you in a relationship?!"

Getting angry with her idiotic questions I twisted her nipples even more

"Ahhhhhhnnnnn! No I’m not in a relationship…. But there are a few that I’m interested in"

Listening to her words I immediately kissed her small pink lips

Rina is mine!

I don’t care if you have a boyfriend, that eunuch of a boyfriend can’t satisfy her

"What…..?"

As she was surprised and tried to move away, I didn't let her

I held her face and inserted my tongue into her small mouth

Licking inside her mouth I didn't leave a single inch of it

I poured in my saliva

"Muchu, Juuru, Muchu"

At first she was surprised, but soon she also pushed her tongue against mine

After enjoying my first kiss I moved my face away, and a small thread of saliva was between our mouths

"Huh, huh"

As I forgot to breathe while kissing I was slightly panting

Both me and Rina are panting while resting on each others shoulders

"How is it?"

"Yes……… I like………."

Rina answered my question straightforwardly, but this time I won’t let her off

"Tell me what is it that you like"

"Well, when you pinched on my nipples and chuu chuuu… I liked them…."

It seems she doesn't know the word kiss

That's why she said chuu chuu trying to imitate the sound

"Who's the guy that you’re interested in?"

She tries to evade answering my question

"Answer it"

As I raised my voice slightly, she spoke the truth

"Yuta"

"Yuta?"

"Yes"

"Whom do you like more Yuta or me?"

"There’s no comparison, of course it is Yuta"

As expected, it seems like the pleasure was not enough

I’ll let you experience more pleasure, then lets see if you can still remember this Yuta!

Her pussy is still under wraps, its time to taste it

But before that….

I took of my shorts and exposed my inflated dick

I’ll definitely make you feel good

So let me feel good too
