My Sex Slave Sister (Family Incest Adult Fiction)

During this winter vacation, my sister whom I haven't seen for many years came to visit me from another place. My sister whom I haven't seen for many years has grown into a tall and graceful beauty with fair skin, tall figure, big breasts, thin waist and long legs. To put it bluntly, she is the kind of person that you want to have sex with just by looking at her.

Because there is not much space at home, my sister has to stay in a hotel when she comes. It's a pity that I can't let her play with me at home.

But one day it happened to be raining, and my sister called me and said she was bored in the hotel and asked me to come over to keep her company and bring some playing cards and food. I gladly agreed.

I knocked on the door, and my sister opened the door for me. Brother, you are finally here. I am so bored, and I am so happy that you come to accompany me.

The air conditioner in the room was turned on very hot. My sister was wearing a black lace nightgown, and her long white legs came into view. It was a bit unbearable to look at, but she was my sister after all, so my eyes immediately shifted away.

My sister is so beautiful and has a great figure!

Haha, my brother is really good at talking.

I put away the things I brought and asked my sister if she wanted to play poker. She said yes, because otherwise she would be bored to death and would have to watch TV series by herself. We started playing poker, and my sister asked me how to calculate the winnings and losses. I said I didn't have any money, and I was embarrassed to ask my sister for money. My sister said with a smile, "It makes you look like you are sure to win." Your smile is so sweet and cute.

I suggest we play nose-scratching.

Okay, then I’ll scratch your nose and kill you, haha.

We won and lost alternately. I pinched my sister's face and scratched her nose, and she pulled my ears and scratched them. We talked and laughed and had a lot of fun.

Scraping the nose all the time is not fun, the sister said, try some other punishment.

How to punish, spanking? I said it jokingly.

Okay, I'll spank you. I'll spank you based on the number of points you lose, hehe.

I said it casually, but I didn't expect my sister to really agree. As a result, I lost the first game.

Haha, turn around and lift your butt high.

I felt a little embarrassed and turned over and lay down. My sister started hitting me, 1.2.3. ...My sister is pretty good at it.

It doesn’t hurt, it doesn’t hurt, I said proudly.

Okay, let’s change the rules. It doesn’t hurt to hit the hands, so just use something to hit.

Okay, I’m afraid of you. It will be terrible if you lose, haha.

As expected, my sister lost. Haha, you set the rules, and you are doomed.

Woo woo... That's terrible. Please be gentle.

Hehe, you deserve it, turn around and lift your butt up.

My sister turned around, stuck out her big butt, and her nightgown was lifted up, exposing her thighs and round butt to me. Seeing this scene, I got hard and my eyes widened. My sister turned her head and asked, "What are you going to hit me with?" with a slightly coquettish voice.

Take the belt, haha.

You want to beat me to death, you little bastard, you are so cruel.

I'm willing to admit defeat, but I will be gentle. I pulled off the belt and hit my sister's big butt. That feeling is very exciting. My sister moaned every time I hit her, which made me even more excited. I felt my dick was so hard.

After the beating, my sister turned around and said, "You bastard, you're so cruel. You beat my butt red. I'm not wearing anything and there's nothing to cover myself. It's not fair."

So what do you want to be fair?

You take your pants off, that's fair.

Okay, I took off my pants, but I forgot that my lower body was already hard, so a huge bulge appeared in front of my sister. My sister looked at it and said, what's wrong, it has become so big, oh~~~~ you were so excited when you spanked me just now, you bad boy.

I looked down at myself and felt a little embarrassed, but my sister seemed very relaxed, and I figured it out.

You actually do this? Well, when I win later, I will beat your little brother. My sister pointed at my lower body and said, "Okay, I'm not afraid of you. If I win, I will beat your little sister, haha."

My sister has noticed that I have entered the role and her face is flushed. She said, "Let's make a big bet and decide the winner in one game. The loser has to listen to the winner and let him control him within ten minutes. Do you dare?"

If you dare, come if you want, no one is afraid of who.

Unfortunately, I lost.

Haha, you're dead. I'm going to kill you.

Well, if you lose, you lose, whatever you want to do.

Take off all your clothes and pants and lie on the bed.

I did as he said, stripped naked and lay on the bed with my cock standing erect.

Your dick is quite big, I think it's about 15 centimeters. I'm going to teach it a lesson. My sister grabbed my dick, pulled my foreskin down with force, exposing the entire glans, and I screamed.

Don't scream, or I'll break it if you scream again. Sister took out a cow tendon from her bag and tied it tightly around the base of my cock. It was already uncomfortable enough with my cock engorged with blood, and now it felt like it was going to explode. Then sister asked me to hold my legs with both hands, and then she whipped my crotch hard with a belt, teaching you a good lesson, little hooligan. Sister hit me really hard and it hurt so much that I screamed again. I was told not to scream, and it looked like I had to gag your mouth, so she took my panties and stuffed them into my mouth. I couldn't scream anymore and could only whimper. She beat me so hard that it hurt terribly, but I was extremely excited. Sister smiled triumphantly while beating me, and her smile was still so sweet.

Then she sat on my face, and used her slippers to slap my cock left and right, and occasionally hit my balls hard. Pain and excitement were intertwined, and liquid kept oozing out of my vaginal opening. My sister twisted my glans hard with her hands and poked my urethra with her fingertips. I was so sad that I couldn't scream, but she rubbed her big butt hard on my face and had a lot of fun.

The time was up and I stood up in embarrassment. I said, "Sister, you are too cruel. I almost died because of you. Now you know how powerful I am. I let you act so arrogantly just now."

Go on, things change, I win, sister, it's your turn, let's see how you die, haha, hum, I'm afraid of you, use it if you have the ability.

I ordered my sister to take off all her clothes. My sister's breasts are quite big, probably a C cup. I will start with them first. I tied my sister's hands behind her back with a belt, and then started to slap her big breasts. My sister also screamed, and then I stuffed her mouth with my underwear. This is called tooth for tooth. After spanking her breasts, I pulled the underwear out of her mouth. My sister cried and said, "It hurts so much, it hurts so much, please be gentle, I can't stand it!" As soon as she finished speaking, I brought my big cock to her face and stuffed it into her mouth, "You slut, stop talking nonsense, use your slutty mouth to serve my brother well, you just gave me enough pain." When I inserted my 15-centimeter dick into her mouth and throat, her tears burst out and her face was covered with tears. I just kept fucking her hard. It was your fault for fucking me like that before. After I felt good, I pulled my dick out and stuffed my underwear back into her mouth.

Next it's your little slut's turn. Spread your legs. Sister is still very obedient. She spread her legs and let her vagina be completely exposed in front of me. Sister's vaginal fluid has wet the sheets. Sister, I didn't expect you to be so slutty. Your pussy is actually quite tender. I'm going to start to torture her, haha. I pinched and pinched her clitoris, sometimes pressing hard and turning in circles, and sometimes grabbing it and pulling it up and down, left and right. My sister couldn't scream, she could only moan and twist her body to try to hide, but it was no use. You can only let me play with you. It took less than ten minutes before my sister had an orgasm.

Fuck, sister, you are so slutty. You have an orgasm just by doing this. Now it's your pussy's turn.

Woo woo woo~~~~~~Sister is speechless and doesn’t know what to say.

Sister, what do you want to say? Do you want me to be harder when I fuck your pussy? Haha, okay, as you wish.

I suddenly inserted two fingers into my sister's pussy and rubbed it hard. My sister suddenly closed her legs and made a loud whimpering sound. I took my hand out and slapped my sister twice, saying, "Fuck you, you slut. Who told you to close your legs?"

I picked up my sister and put her on a chair, letting her legs fit through the two armrests of the chair to prevent her legs from closing. You stupid slut, how are you going to put it together like this?

My sister whispered "Hmm~~~ Hmm~~~~~"

I started to finger my sister's pussy again, quickly and forcefully. Her legs tried hard to move together but couldn't close. My sister moaned in what seemed like pain, and kept shaking her head with tears in her eyes. But after a while, my sister had another orgasm, accompanied by body twitching and strong moans. This time, a lot of liquid spurted out of her urethra. Yes, my sister had an orgasm.

Seeing my beautiful sister being so sexy, I couldn't bear it anymore and I inserted my big cock into my sister's pussy. I fucked you hard, you slut, I'm going to fuck you to death, I cursed you as I fucked you, I grabbed my sister's tits hard with my hands, I want to bite them hard and burst them.

We did this for a few minutes, and then my sister climaxed again with a twitch.

No way, my dear sister, you climaxed too quickly, haha, I took the panties out of your mouth, and you gasped, hurry up, keep going, fuck me, fuck me to death, hurry up, okay, I'll make you feel so good, you slut, bitch, beast in heat.

I continued to fuck my sister, grabbing her breasts while fucking her, then slapping them hard, making their breasts shake non-stop. My sister kept screaming, seeming to be in pain, but also very happy. Fuck me, ah~ah~, harder, fuck me to death, ah~harder, harder, beat me to death, kill me, ah~~~~~~~~ah~~~~~~~~~~~My sister's climax came again…

In just less than fifteen minutes, my sister had climaxed three times. This is an absolute slut.

I put my sister on the bed and asked her to raise her butt towards me. I started fucking her from behind. Sister, your butt is so round. It feels so good to fuck you from behind. It’s so elastic.

My sister was using her ass to please me while she was crying and moaning, "I can't take it anymore, I'm going to push it so deep from behind, it's almost hitting my uterus, it hurts so much, I'm going to fuck your uterus to pieces, fuck you, you bitch, you cunt, you bitch." The more she pretended to be in pain, the more excited I became. I picked up a belt and fucked her while whipping her with it, slap~ slap~ slap. With the sound of the belt, belt marks were left on my sister's ass and thighs.

It’s coming, it’s coming, it’s coming again, ah~ah~~~~Sister’s climax is coming again. After the climax, my sister collapsed.

You bitch, this won’t work. I turned my sister over, lifted her up by the waist, and used my arms to move back and forth on my cock, moving my hips back and forth, fiercely and at a very fast speed. This time, my sister reached her orgasm in less than a minute, and her urethra squirted water again. Her voice seemed to be stuck in her throat, and she couldn’t scream out. In this position, my sister reached orgasm three times in a row. It was very tiring, so I put my sister down. She looked like she was about to faint, and her eyes were slightly rolled back. So I stopped, and I also felt like I wanted to ejaculate. I inserted my cock into my sister's mouth and said, "Sister, you must be tired. Let me give you some semen to replenish you." After a while, I ejaculated. A lot, filling up your mouth. She kept swallowing it and seemed to be enjoying it. After swallowing it, she licked my glans with her tongue, which was very slutty.

My dear sister, I haven’t seen you for many years. I didn’t expect that you have become such a slut. Haha, you will be my sex slave from now on. Stop here today and come to my house another day, and I will torture you again.

My sister nodded and seemed to be very expectant. "Well, okay, brother, I like you doing this. I want to be your sex slave. You can do anything to me and I will be very happy."

Very good, sister is a good toy, you will have fun in the next few days, you can rest today.
