Sister's Underwear (Family Incest Adult Fiction)

Now I am a freshman in high school. In my family, besides my parents, the one who loves me the most is my sister who is currently studying at university.

Since we were young, our parents have always neglected my sister and me because of their busy work. Therefore, my sister took on the responsibility of a mother and always cared about me.

Gradually, as I grew older, I understood the things between men and women, and began to have fantasies about my sister.

"Oh, sister, your breasts are so soft and feel so good to touch. "I hid under the quilt in my room, muttering to myself and masturbating. The last shot of force

When I came out, both my hands were covered with thick semen. "Sister, it would be nice if I could make love with you once. "I thought to myself.

One time when I passed by the laundry basket before taking a shower, I suddenly found a pair of pink panties on the top layer. They were what my sister had just changed out of. I

I looked around and found that there was no one else, so I grabbed my sister's underwear at lightning speed and rushed into the bathroom. As soon as I closed the door, I took out

The swollen cock has wrapped around his underwear. Looking at the lace on the panties, I imagined my sister naked. Although I have never seen my sister

She is really naked, but she has appeared in my fantasy countless times. I always fantasize about my sister using her legs to wrap around my body.

Seeing this, I couldn't help but ejaculate, and the lace panties were filled with my smelly semen. I was afraid of being scolded by my sister, so I hurriedly

Rinse it out with water, stuff it back into the bottom shelf of the laundry basket, and hope no one finds it.

With the experience from last time, I became bolder. One time, I sneaked into my sister's room when no one was around. As soon as I stepped in, I smelled

Smelling that unique scent of my sister, I ran to the closet, opened the bottom drawer, and saw many underwear full of youthful scent. I picked a piece of cloth.

She put on sexy red lingerie that covered half of her breasts, put her face close to her, and inhaled her sister's scent vigorously. It was as if I could really lean over and suck my sister's breasts. Then, I

She lay on her sister's bed and started masturbating using the only thong she had in her collection. I didn't expect that my sister, who usually looks very shy, could be so

Sexy panties. So, in the room filled with my sister's scent, coupled with an unprecedented excitement, I quickly surrendered, and clumps of white semen splashed out.

On the floor of my sister's room. After that, I quickly packed up and left. However, I also took away a trophy - the thong.

The next day, my sister seemed to notice that her underwear was missing, and she took the opportunity to ask me several times if anyone had entered her room, but I always played dumb. I believe my sister is embarrassed

He complained to his mom, so I didn't care. Just after I masturbated several times with my sister's thong, I was finally discovered.

Hey, brother, lend me your book, are you... " My sister suddenly opened the door of my room. At that time, I was holding my sister's favorite and stroking my penis, when suddenly

The fright made me panic.

"What are you doing? Isn't that my underwear? You actually..." My sister was so angry that she couldn't speak.

Because I was afraid of being discovered by my parents, I quickly covered her mouth, kicked the door shut and locked it. "That's not the case, sis. "I explained," I just

I was curious for a moment, so... "

At this time, my sister seemed to be less angry, but her face was still stern. "We are siblings, we cannot have such incestuous fantasies. "

I pretended to be innocent. "Because... because my parents don't care about me, and my classmates are not nice to me, so I... I..." I'm fake.

Pretend to cry.

After hearing what I said, my sister felt distressed. She came forward, hugged me, and said softly, "You shouldn't do such a thing." "

I hid in my sister's arms, took the opportunity to take advantage of her, and said pitifully, "But my body is so strange, it's always hot. "

My elder sister immediately asked worriedly, "What's wrong with you? Is there any problem? Let me take a look." "

I pretended to resist shyly, but my sister pulled my pants off. A thick cock popped out immediately, and I said, "That's it,

It wouldn't get smaller, so I had to keep rubbing it, and then I would pee white stuff out, and that would fix it. "I pretended to be mentally retarded.

My sister blushed and said, "I have a way to treat it, but you can't tell Dad or Mom." "I nodded quickly and agreed. Then my sister lowered her head and took my vagina in her mouth

It was circling around my horse's eye. Electric-like sensations spread to my brain and I almost screamed out in pleasure.

Guide me to insert into her honey pot. A feeling of firmness that I had never experienced before made me feel extremely comfortable. After a few thrusts, I couldn't help but ejaculate, and all of my semen went into my sister's belly.

"Sorry, sis, I already came. "I said in annoyance.

"Don't be nervous, it's your first time, so it will be quick. "Hearing my sister's comfort, my disappointing brother immediately revived and slowly changed from his original state.

Bigger, even bigger than before, and it filled my sister's entire vagina again. I regained my vigor and began to imitate the various techniques and postures of the male actors in the porn movies.

There were all kinds of tricks, which made her sister very happy.

"Brother...oh...oh, why does it feel so good? Where did you learn this from? Ah...ah...ah..." Sister was already incoherent.

"I've been preparing for a long time, and it finally comes in handy. "I said proudly.

From the train bento to the lotus position, and finally the sprint missionary position, now my sister and I are about to climax.
