My sister-in-law is actually a virgin (family incest adult novel)

My sister-in-law is a virgin

My eldest brother went to Nantou on a business trip, and every day only my eldest sister-in-law and I were left at home. Because I don't have a job yet, my eldest sister-in-law supports me. My eldest sister-in-law works as a model for advertising clothes. She makes a lot of money. Every day when she comes home, she wears the clothes from the advertisement. It's really charming.

Sometimes she wears miniskirts and low-cut clothes. Oh! I always want to get an erection, but I dare not get an erection. My sister-in-law knows that she will get an erection when she wears a miniskirt. She also knows that I often stare at her breasts, so she deliberately tempts me.

Suddenly one day, my sister-in-law asked for leave and stayed at home. She wore a miniskirt and low-cut clothes again. But this time it was different. Her miniskirt was so short that you could see her underwear, but you couldn't see it. My heart beat faster and my sister-in-law said, "Your brother is not at home recently, so you can do whatever you want at home."

I then said: "Sister-in-law! Don't you feel bored staying at home on leave? Why do you want to take leave?", Sister-in-law said: "I took leave to stay at home to accompany you!" I asked Sister-in-law: "Has my brother ever made love with you?"

The sister-in-law said: "Have sex? Please, your brother's thing is only 10 centimeters, thin and short, I haven't done it with him, and he is still practicing."

I asked: "Sister-in-law, do you want to experience it?" Sister-in-law said: "With whom? With you?"

I said: "That's right! I'm so bored now, let's just give it a try!" My sister-in-law said: "But I'm not mentally prepared yet, how big is yours!" I said: "About 21 centimeters! Do you want to give it a try?"

My sister-in-law reluctantly said: "Oh! Okay! But can you please not pull down your clothes and miniskirt!" I said: "Okay! But you have to pull down your underwear!" So, my sister-in-law and I came to the room, locked the door, and my sister-in-law took off her underwear. We both lay on the bed together, ready to do it. I knew that my sister-in-law was still a virgin.

So I couldn't use too much force or too fast. We were moving very slowly. I kissed my sister-in-law's neck and shoulders, repeatedly. My lower body started to get hard. When I was about to insert my penis into her, I didn't expect that her vagina was so tight. It was difficult to insert at the beginning. My sister-in-law kept moaning.

My sister-in-law said: "Oh my God! Your vagina is so thick! It feels so good! Can you thrust in and out?" I said: "Your vagina is so tight, it's hard to thrust in and out, I'm afraid it will hurt, I'll wait until your vagina is a little wet before thrusting in and out."

So I slowly penetrated into my sister-in-law's vagina. My sister-in-law felt more and more comfortable, and I felt very comfortable too. I kept kissing my sister-in-law's neck and shoulders. Suddenly I stopped, looked at my sister-in-law's sexy lips, and kissed her gently. Oh! It felt so good. I kept going deeper and deeper, but it was blocked by my sister-in-law's miniskirt.

So I said to my sister-in-law: "Sister-in-law, I'm going to start thrusting." My sister-in-law said: "Okay! You can go deeper." I gently lifted my sister-in-law's miniskirt a little higher, and I completely inserted my thing into my sister-in-law's vagina. I seemed to have hit my sister-in-law's uterus, because I couldn't push any further, so I started thrusting, and I didn't pull my thing out.

My speed was getting faster and faster, and my sister-in-law's moans were getting louder and louder. She said, "I can't hold it any longer! I don't know how to describe this feeling, I think I'm having an orgasm." I said, "I'm having an orgasm so quickly!"

After saying this, I also felt comfortable and happy, and I seemed to be about to orgasm. My sister-in-law kept tightening her vagina. Oh! God! How could it be so tight? It was so tight that I could hardly bear it. My sister-in-law tightened it even more, and it felt like the vagina of an elementary school student. It was so tight, and my sister-in-law's vaginal fluid was getting more and more, and much of it flowed out of her vagina and flowed onto the bed.

My sister-in-law's vagina was getting more and more moist. I wanted to thrust faster, but I couldn't. My sister-in-law's vagina was getting tighter and tighter, so tight that I couldn't thrust. It seemed that my sister-in-law wouldn't let me go. I stopped thrusting.

I said, "Sister-in-law, please stop squeezing me tighter, it's too tight for me to thrust in and out!" Sister-in-law said, "But I can't control it either!" But sister-in-law seemed to have stopped tightening, which should be the tightest state of sister-in-law's vagina. I wanted to thrust in and out very badly, but suddenly, a stream of hot semen came out of me. I tried very hard to control it and not ejaculate.

I said: "Sister-in-law, I'm sorry, I forgot to wear a condom just now, I can't hold it anymore, I'm about to ejaculate!" Sister-in-law said: "It's okay, just ejaculate" I said: "What if you are pregnant and your brother knows?" Sister-in-law said: "Let's talk about it when I get pregnant!"

After hearing what my sister-in-law said, I ejaculated boldly. This feeling was so great and so pleasant. It was my first time having such an experience. I didn't expect that I would ejaculate so much. I could feel that my semen filled my sister-in-law's uterus and even reached the fallopian tubes. After more than 30 seconds, my semen had filled my sister-in-law's entire vagina.

It was full and flowing out from the vagina of my sister-in-law. The bed sheet was wet. I started to kiss her shoulders, lips and neck again. I kept kissing her over and over again. I was very happy to see her neck and shoulders were white and tender. At that time, my sister-in-law's vagina relaxed a little, so I pulled my thing out.

I said, "Sister-in-law, let me get some lubricant." Sister-in-law asked, "Why do you need lubricant?" I said, "Sister-in-law, because your vagina is too tight, I need to lubricate it so that it will be easier to thrust in and out."

I took the lubricant as quickly as possible. Fortunately, my thing was not soft yet, so I could continue. I squeezed the lubricant into my sister-in-law's vagina with force, and then I inserted my penis into her vagina. At this time, her vagina began to tighten desperately. I felt so comfortable. Her vaginal fluid began to increase. I was about to start thrusting, but I didn't expect that I couldn't move. Oh my God! How could this happen?

My sister-in-law said, "Didn't you apply some lubricant just now? Why can't you move?" I said, "Yes! How could this happen?" My sister-in-law said, "Are you sure that what you took was really lubricant?" I said, "It should be! Let me see, ah! ah! ah! I took the wrong thing, I took the super adhesive!"

My sister-in-law said: "What should we do? Don't we have to keep doing this?" I said: "When it gets soft, you can pull it out." I looked at my watch and found that we had been doing it for more than three hours. At this time, I wanted to ejaculate again. Oh! I ejaculated for the second time, and my sister-in-law suddenly hugged my body.

I said to my sister-in-law: "Sister-in-law, can I ask you a question?" My sister-in-law said: "What question?" I said: "Sister-in-law, do you love me?" My sister-in-law said: "I only love you in bed, but not at other times." I said: "Yes! Sister-in-law, I really love you, but don't let my brother know!"

The eldest sister-in-law said: "I won't tell my eldest brother. I know you love me very much because you always stare at my miniskirt and sometimes look at my breasts. Don't think I don't know."

At this time, my penis started to soften, so I pulled it out of my sister-in-law's vagina. Oh! My glans was red and swollen, and my sister-in-law laughed. She finally agreed to let me see her naked body, but I didn't get hard. It might be because I had been doing it for more than three hours, and my penis was too hard! In order to clean up the mess, my sister-in-law and I took the sheets to wash.

We took off all the clothes and washed them. We took a hot bath together. While bathing, my sister-in-law sucked my penis, and I licked her labia. Her pubic hair was very neat and clean, not messy and abundant. I didn't expect that a virgin man and a virgin woman could do it for three hours. This was my first time, and also my sister-in-law's first time.

It was also my first time with my eldest sister-in-law. This time really left a deep impression on me. This is real, don't think it's fake. The funniest thing during our lovemaking was that I actually used the lubricant as a strong adhesive. My eldest brother's business trip gave me the opportunity to have sex with my eldest sister-in-law. We had sex every day after that, and we did it for three or four hours each time until my eldest brother came back.
