My Third Sister (Family Incest Adult Novel)

My third sister is 41 years old this year and works as the human resources director in a company. Although she is in her forties, there is no trace of time on her body. Her figure is still very well maintained. My third sister is not very beautiful, but her figure is absolutely first-class. The figure of 35D-26-38 is not something that ordinary women can have.

I have liked my third sister since I was a child. I think she is very kind and she would buy me toys and candies from time to time. Therefore, we have a very good relationship and I also like being with my third sister. Later, they moved to another town because of work, so I didn’t have many opportunities to meet my third sister. As I get older, my feelings towards my third sister are no longer the same as when I was a child. I began to feel that my third sister is very feminine and sexy, and began to appreciate her body.

I remember that I stayed at my third sister's house for a week during the summer vacation when I was in the first year of high school. During that week, by chance, I saw my third sister changing clothes and her naked body. Her fair and rosy skin, sexy body curves, slender thighs, and big white buttocks. The most eye-catching and amazing thing were the pair of 35D (I found out later when I peeked at my third sister's bra) big breasts on her chest. The firm, plump and white breasts and the bright red areolas were really a pair of impeccable works of art.

From that time on, I regarded my third sister as the object of my sexual fantasies. My mind was always thinking about her naked body, imagining myself kissing her, taking a bath with her, and even having sex with her. Whenever I have the chance to stay at my third sister's house, I will secretly take her bra and panties to satisfy my sexual desire. After entering university, because the study was easier, my sexual desires became stronger and stronger. Every night before going to bed, I would think of my third sister, her naked body, her 35D breasts, and her 38 beautiful buttocks. In my mind, I would weave one story after another about how to have sex with her. I also started collecting some pornographic novels on the Internet. In short, in my heart I really wanted to have sex with my third sister, I really wanted to, really wanted to. Finally, my hard work paid off. During last summer vacation, I finally had the opportunity to taste this bottle of "wine" from my third sister.

During last summer vacation, when I was still at home playing games, watching TV and sleeping to pass the time, the phone at home suddenly rang. It turned out to be my third sister. She said that her son was going to take the high school entrance examination, and his grades were not very good. She wanted me to go and tutor him for a week. It would be boring at home anyway, and I could see the goddess of my dreams, so I agreed readily, packed some clothes and took a bus to my third sister's house. In the evening, I finally arrived at my third sister's house. The sexy third sister opened the door to greet me. She was wearing a black fitness suit. She might have just been doing fitness exercises and had sweated a lot. The tight clothes were tightly attached to her body. The shape of her bra was clearly visible. The slender curves of her whole body were also exposed under the tight clothes. When my third sister saw that I didn't enter the door or say anything, but just looked at her, she smiled and said, "Why, what are you looking at that you don't even recognize your third sister?"

I also smiled and said, "I thought I walked into the wrong door. How could such a beautiful woman open the door?"

The third sister smiled and said, "You are a little brat. You are even joking with me. Come in quickly."

After I went in and sat down, I looked around. My third sister's house had not changed much, with a spacious hall, smooth marble floors, and soft sofas. At this time, my third sister went to pour me tea. From the back, my third sister's slender figure of 1.65 meters was really speechless. Under the tight fitness clothes, I could clearly see the bra straps and traces of underwear. Her plump buttocks looked particularly big under the fitness clothes. I really wanted to touch her. After a while, my third sister poured the tea and put it on the table. I said, "Third sister, are you the only one at home?"

The third sister said, "Your nephew has gone to a friend's house and will be back very late. Your brother-in-law has gone on a business trip to Nansha for three months. He has been gone for more than a month now. You sit down and watch TV for a while. It's still early. I'll wait for a while and cook. I'll go do some aerobics first."

"Okay, Third Sister, just do your thing. I can handle it on my own."

I watched TV for a while out of boredom and felt that I had nothing to do. Suddenly, I wanted to go and see my third sister dancing aerobics, so I quietly went upstairs and came to her door. I heard bursts of music coming from inside and the door seemed to be unlocked. I gently pushed the door open, revealing a gap. I saw my third sister doing the movements according to the video tape on TV. She was standing with her hands on her hips and following the movements of the people on TV. Her two beautiful breasts were shaking because of the movement of her body. Even though they were covered by a bra, her breasts were too big and they still bounced up and down and left and right. Then she knelt on the ground with her knees, spread her thighs, and lay on her back. The tights wrapped around her were soaked with sweat, and the fabric of her lower body looked even more transparent. The fitness clothes were tightly attached to her skin, and the outline of the bra and panties inside the clothes was clearly visible. When she was doing a waist-twisting exercise, she lost her balance due to the excessive movement and fell to the ground with a cry of "Ouch". I quickly pushed the door open and helped her up, asking, "Third sister, are you okay?"

"It's nothing, I just got a knot in my waist and it hurts now."

"Come, rest on the bed for a while." I helped my third sister walk towards her big bed. My arm accidentally touched her breasts. They were really elastic. Although she was in her forties, her breasts showed no signs of looseness or sagging like those of middle-aged women. They were still so firm and elastic. I helped my third sister lie down on the bed.

"Third sister, are you in pain?"

"It hurts a little, but it shouldn't be a big problem. I'll lie down and rest for a while."

"Let me give you a massage, it will feel better."

"Ah," the third sister woke up, she turned around and said, "Oh, I actually fell asleep, how long have I slept?" I said, "Just a while, does your waist still hurt now?"

"It seems to be fine. Oh, I'm all sweaty. I'll take a shower first, and then cook."

"Okay, Third Sister, I'll be out first."

So I went back to the hall to continue watching TV, and then my third sister came down to the bathroom to take a shower. I saw that she was holding a light blue pajamas with a set of red underwear tucked inside. I didn't expect my third sister to be so avant-garde. The third sister also glanced at me, as if she knew I was staring at the bra in her hand. My third sister went in to take a shower. I couldn't concentrate on watching TV outside. I just listened quietly to the sound of water inside. I once walked outside the bathroom and wanted to peek at my third sister taking a shower through the air vent below, but I was afraid that she would find out, so I just squatted by the door and listened. Sometimes I could hear the sound of her rubbing soap, and even a few moans. Ah, my third sister might be masturbating? After listening for about ten minutes, the third sister started flushing and was about to come out. I hurried back to the hall and bumped into a stool in my rush. I quickly straightened it and returned to the sofa to watch TV. After a while, the third sister finally came out. She was wearing that light blue translucent pajamas and she looked really sexy. I could vaguely see the red underwear underneath. I could hardly take my eyes away.

The third sister looked at the clock and said, "Ah, it's so late. I'm going to cook now. You can watch TV for a while."

About twenty minutes later, my third sister called me from the kitchen to eat. She had already laid out the dishes, so we sat down to eat. She sat next to me. We finished the meal quickly. When cleaning up the dishes, she accidentally dropped her chopsticks on the ground. She bent down to pick them up. At this time, the collar of her pajamas was open a lot. I looked inside through the collar. My third sister's breasts were fully exposed under the red bra. They were bulging and very tempting. A deep cleavage passed through two towering peaks. In such a beautiful view, my cock immediately swelled up. It only took a while for the third sister to pack up. I also returned to the hall. After a while, my third sister came to watch TV. She sat next to me. Waves of fragrance wafted over, and she was wearing a translucent pajamas. Her body attracted my attention like a magnet. We chatted while watching TV. My third sister told me about my nephew's study situation, and I also told her about the situation at home.

The next day, I got up at eight o'clock. My nephew was still sleeping. He didn't come back until after two o'clock last night. I went to the bathroom to brush my teeth. When I passed the kitchen, I saw my third sister making breakfast. My third sister was wearing a white sleeveless T-shirt and a light yellow skirt today. Both were very tight, and you could see the shape of her underwear and bra inside, but the underwear was changed to white, not red like last night.

I said, "Third sister, today is Saturday, why don't you sleep in a little bit later?"

The third sister said, "I'm used to it. I can't fall asleep no matter how hard I try. Is my nephew still sleeping?"

"Yes, he came back very late last night."

"Then forget about him, let's eat first."

While having breakfast, I asked my third sister where she was going on her holiday. She said she was going out shopping and asked me if I wanted to go with her. Wow, if I could go out alone with my third sister, I would definitely agree. After breakfast, I sat at home for a while. Around nine o'clock, my third sister and I drove to the shopping mall in the town to go shopping. We walked from the first floor to the seventh floor, sat for a while in the food street on the seventh floor, and drank some drinks. When we walked down from the seventh floor, passing by the clothing show on the fourth floor, I told my third sister that I wanted to go in and buy something, and asked her to wait for me for a while. Then I went to the men's underwear area of ​​the clothing show by myself. Because the underwear I brought was not enough, I had to buy another pair, and I picked for a while. I chose a large black size and turned around to pay when I suddenly found my third sister standing behind me. She looked at me with a smile and said, "I'm just buying underwear, why are you so secretive? I didn't expect you to wear a large size."

I was a little embarrassed and said, "Third sister, you have been following me all the time. I am 30 years old, of course I wear a large size. What's so strange about that? Third sister, are you going to buy something recently?"

The third sister said, "Oh, if you hadn't told me I would have forgotten about it. I was going to buy a set to take back."

I also specifically asked my third sister if she would buy whatever I chose, and she said yes. So I chose that one, and my third sister came over to take a look, then smiled at me and asked the waiter to pack up all the clothes. I thought to myself: Oh, Third Sister really wants it. I thought she was just talking. Not all women dare to wear such sexy pajamas, especially a middle-aged woman like Third Sister.

After buying the underwear, we drove home. It was almost twelve o'clock when we got home. My nephew had already gotten up and was watching TV. The third sister took the underwear back to the bedroom and went to cook. While we were having dinner, my nephew said he had to go back to school in the afternoon as he had something to do. After dinner, he watched TV for a while and then went out. My third sister said she was a little sleepy and wanted to take a nap. After a while, I also wanted to sleep, so I turned off the TV and went back to my nephew's room to take a nap. I don't know how long I slept when I was suddenly awakened by a phone call. My third sister answered the phone, and I was secretly watching the situation in the hall outside the door. I saw my third sister said "Oh, oh, oh" a few times and then hung up. Then she hurried back to the room, seeming very nervous. So I walked over to see what was going on. When I got to the door of my third sister's room and was about to knock, I found that the door was not closed, but just ajar. Maybe my third sister thought I was asleep and didn't even close the door.

So I gently pushed open a gap and looked inside. Wow, it turned out that my third sister was changing clothes in front of the mirror. She had just taken off her outer coat, immediately revealing her smooth back and the white bra inside. Then she gently unbuttoned her skirt and slowly pulled down the zipper. Oh my god! This kind of teasing made my crotch, which was already about to burst, even more uncomfortable. The black lace panties finally appeared in front of me. They were narrow and small mesh hollow panties. The feeling of wearing them on my mother was completely different from when I saw them in the laundry basket. She reached behind her and unbuttoned her bra. As the bra loosened, a pair of snow-white breasts popped out. They were so big and firm. Then she gently took off her panties, revealing her big, plump butt. From behind, I could clearly see my third sister's naked body in the mirror. She was like an impeccable statue of Venus. My third sister’s naked body was so beautiful, so beautiful that I almost couldn’t help but rush over and hug her. But I still held back. My third sister bent down and took out a set of black underwear from the cabinet! Oh my god!

My blood was already boiling, and when my third sister bent down, I saw it. From behind I could clearly see a thin slit running down her buttocks, with many fine pubic hairs on the side. That was her vulva, her pussy. The lingerie was also extremely sexy, with very thin black stockings that gave off a wonderful sheen, black lace bikini panties, and a black front-opening bra. The third sister quickly put on that set of underwear and pantyhose. Wow, looking in the mirror, I saw that the third sister was so beautiful and sexy in the sexy underwear. I really wanted to rush up to hug her, grab her big breasts, and fuck her pussy.

Seeing this my cock was swollen and painful, I hurried to the bathroom on the second floor to masturbate, and came in less than two minutes. Ah, it was so comfortable to masturbate while imagining the extremely sexy Third Sister. When I was still trying to wipe the semen off the glans with a tissue, Third Sister suddenly rushed in and saw it all. Although I had already ejaculated, my penis was still very swollen. Third Sister had already changed into a red suit. She quickly turned her head to the other side and said, "Oh, sorry, I didn't know you were there." Although Third Sister saw the other side, her eyes still glanced at my thick cock from time to time. I also put my cock back into my underwear and said, "It's my fault, I didn't close the door." Then I quickly walked out of the bathroom and went back to the room. After a while, Third Sister also came out of the bathroom and hurried downstairs and out the door!
