First contact with sister’s butt

My sister is five years older than me, 170cm tall, with breasts as big as grapefruits, 54kg, long and slender hands and feet, and a very beautiful oval face, a bit like Weng Hong. As soon as I was a child, the doctor cut off my foreskin. Although I was already in the second grade of junior high School at the time, my physique was already very big, my penis was nearly 15cm, and my height was nearly 170cm, which was almost the same as my sister, but I had a baby face, so my Family didn’t care about me, and they even let me sleep with my sister when we were traveling. Same bed. I usually listen to my classmates talk about romantic affairs at School, and sometimes secretly watch Channel 4's Lock Code program at Home, so I have long been very curious about women's bodies. My sister dresses mainly for comfort at Home. She usually only wears a spaghetti-strap dress that exposes her deep cleavage. The length only covers her buttocks. She walks around the house, sits or lies on the sofa. Her slender figure and snow-white SMooth and tender skin, coupled with her soft and slender waist and slender and straight legs, make me daydream all the time. My sister likes to wear light-colored one-piece shirts and dresses, but the light tranSMittance of the material is very good. Under the light, it is almost translucent. The full breasts are bulging in the shirt, and the two spots on the chest are red and the delicate nipples are red. Also clearly prominent. Occasionally, my sister would drink some red wine or plum wine. The slight alcohol dyed her beautiful face into a white and rosy color, making her look really bright and attractive. The moist red lips after drinking and the slightly intoxicated eyes exude a sultry charm, which makes me often masturbate while fantasizing about it. Since I came back from my last trip, my sister has become even more beautiful. I just imagined it before, but now it is a reality. My sister is also naked at Home and wears a shirt and skirt to walk around the house, which makes it easier for me to move my hands and feet. She only wears panties unless my parents are at Home. But my Family runs a 24hr supermarket, and my parents don’t come Home until very late, so there are only my sister and me at Home, a pair of cubs addicted to erotic games. I like to touch my sister's slender white ankles while watching TV. My sister likes to lie on her side on the sofa and bend her legs up. I sit next to me and reach out to play with her ankles, gently touching her ankles with my fingers. As her curves were explored upward from the ankles, my sister's soft legs often bent involuntarily due to my slow movements. I even carefully played with my sister's white and delicate feet, teasing the SMall and round toes, licking them one by one with my tongue, and sucking greedily, making my sister often moan involuntarily, "Ah..." And touched my face with the other slender white foot. My sister likes me to carefully play with her white and delicate feet, and use my tongue to lick and suck them one by one. The numb feeling often makes her fall into the trap of lust and cannot extricate herself. She constantly caters to my entry and endures the touch of my tongue. The fingers teased one after another, and the whole person fell deeply into the sensual world of lust. Sometimes she would imitate Japanese movies, gently licking and sucking every inch of her skin with her tongue, and caressing her white body with her fingers. In addition to licking and sucking her sister's honey hole, she even tried to insert her tongue into her Vagina.Licking her Asshole made her gasp, and her Asshole opened and closed with excitement. After being teased by me a few times, my sister couldn't bear it anymore and asked me to gently insert my fingers into it. She said that the inside of her Asshole after being licked by me felt numb and comfortable, but it was also itchy and wanted to be penetrated. . One afternoon while watching TV, I teased my sister again, licking her delicate white feet all the way to her slender white ankles, and then kissed my sister's Vagina along her slender legs, which was already dripping wet. Waiting for my invasion, my sister couldn't stand it anymore and rubbed her white and plump breasts through her T-shirt, Moaning seductively "Hmm... um..." incessantly. I ignored my sister's moans and seductive twists of her body, and continued to tease her. I tried to use my fingers to cover my sister's Vagina with love fluid, and slowly and gently teased her beautiful little Asshole. My sister moaned loudly "Oh..." and shouted: "Good Brother, dear Brother, fuck me quickly, I want it so much...ah..." I wanted my sister to lie on the sofa and raise her buttocks High up, I spread her ass with my hands, inserted my tongue into the Asshole and licked it. My sister's buttocks kept catering to my movements, and she shouted: "Stop licking, fuck me quickly, my sister can't bear it." Then I inserted my index finger into my sister's Asshole and pushed it all the way to the bottom. She seemed to be overwhelmed by my sudden move. The move stimulated me, and I couldn't help shouting: "Ah... it hurts a bit... but it's so numb... ah... I can't stand it..." I was tickled by my sister's moans, and I carefully looked at her erection. The upturned buttocks are so plump and elastic, and the skin is so SMooth and delicate. The more I think about it, the faster I move my hands. The louder my sister screams, and the buttocks also actively shake back and forth and twist left and right to cater to my fingers. action. Suddenly I wanted to know if my sister’s butt SMelled bad, so I took my hand out and SMelled it, but it didn’t really happen. sister, she turned back and hummed: "Oh... don't stop, sister, it feels so comfortable!" Then I won't be polite and squeezed in with my index and middle fingers. It was not easy to get in at first, especially at the joints, where it was not easy to squeeze in. After the joint went in, I felt it became extremely tight. My sister also made a cry of pain and told me to slow down. Later, my sister's Asshole slowly relaxed. At this time, I kept moving my fingers in and out, enjoying the tightness of my sister's Asshole and her wanton cries: "Ah... be gentle... it hurts and numbs me..." while I played with her. While rubbing her sister's butt, she would sometimes rub her pussy with the little finger of the hand inserted into her butt. After playing like this for about 30 minutes, my sister's body tensed and relaxed twice. Finally, she collapsed on the sofa, her whole body limp and at my mercy. Later, I couldn't stand it anymore, so I pulled out my fingers. At this time, my sister's Asshole was already quite soft and moist. I pushed her ass up high and inserted my penis hard into her Asshole. My sister cried out "Ah..." and I felt that the pressure on my penis, which I had pushed forward with all my strength, suddenly eased. I successfully inserted it into my sister's little Asshole for the first time, which was even better than my sister's little pussy. Even tighter. I started pumping slowly,Experience the tenderness of my sister’s ass. My sister seemed to have already integrated into it. From time to time, she took the initiative to thrust back and forth, and bumped her butt against my testicles and thighs. She gasped repeatedly and said, "Ah...ah...so comfortable...", and she also speeded up the swinging speed. I pushed out harder, watching my cock go in and out of my sister's SMooth ass, rubbing her clitoris, and pinching her slutty and swaying breasts from time to time. Slowly, my sister swung her hips back and forth like crazy, and her long shawl hair was dancing wildly as her sister shook her head crazily. Her moans became louder and louder: "Oh...fuck me to death..." Fuck sister to death...oh...", I pumped harder and crazily. Gradually, my sister's moans became louder and louder: "Oh... don't... don't stop... I can't stand it anymore...", and the whole living room was almost filled with her echo. Her buttocks kept twisting, and I was so excited that I hugged her tightly from behind, and my buttocks kept thrusting wildly. Until the Semen was ejaculated in her Anus, I hugged her softly. Lie on the sofa until dark. The next morning after the incident, my sister told me, "You were so rude yesterday. It made my sister's butt hurt so much that I almost couldn't poop today."
