I and the patient gang-raped the nurse sister [ (Transformation series adult novel)

I have an older sister with big breasts and a round, perky butt. She has been the object of my masturbation since I was a child.

My sister is a nurse and comes home very late every night. Their hospital is moving recently, so she has to work overtime every night. It's already two o'clock today and my sister hasn't come back yet.

Sometimes my sister comes home late, but tonight is the latest. He must not have gotten off work yet. So I was secretly delighted and excitedly entered my sister's bedroom, ready to molest my beautiful sister's black underwear. The 16-inch D cup was embroidered with white patterns. I buried my face in the cup and deeply inhaled my sister's scent. My sister has such a nice figure and looks pure and pretty, why would she wear so many colors of underwear, especially this black underwear that I have never seen or used before, it looks so lewd...

"Sister... let me fuck you..." After masturbating with my sister's panties until this point, I got up and put on the black boxer shorts embroidered with white patterns on my head, and then used the cup of the black bra to wrap my penis, and the other cup rubbed the glans. "Ah..." It's finally over. Watching the semen spurting out forcefully, the thick milky white juice shot into the cup one stream after another. My sister's black D cup was filled with my white semen.

It was almost 1 o'clock and my sister hadn't come back yet, so I decided to go to the hospital to find her. It was already 2 o'clock when we arrived at the hospital. Due to the relocation, there was almost no one in the hospital. My sister said that she was the only one on duty this morning. I saw the light in one ward was still on, and thought my sister must be there!

I went upstairs and came to the door of the ward. I looked through the crack and saw that my sister was indeed inside. There is also a pockmarked face lying on the bed and a bald man taking care of him. My sister was about to give Ma Lian an injection, and she immediately lay down on the bed. I looked at her butt, which was raised high and twisted slightly. I could even see her bright red lace hollow panties at the root of her thighs under her short skirt.

My cock is hard. Just as I was about to masturbate, something I could not have imagined happened. The bald man suddenly grabbed my sister's waist, threw her onto another bed, and shouted excitedly: "Brother, come on, you can finally fuck this slut!" My sister was so scared that she collapsed on the bed, unable to utter a word. At this time, Ma Lian got up from the bed and said with a lewd smile: "I have wanted to fuck you for a long time, Baldy, you go first, fuck her hard!"

The bald man pressed my sister on the edge of the bed, and pressed his trembling hands on a bald head. The bald head drilled under the mini skirt and made a "chirp" sound, and it seemed that he was sucking my sister's pussy.

Damn bald head! Seeing this scene made me shocked and angry. How could my sister do such a thing with that old bald guy? The old bald man held my sister's buttocks with both hands and licked her vagina. Her stockings and yellow silk panties had been pulled down to her ankles, and her light green suit was also stripped off to reveal her graceful shoulders. Her protruding breasts were still covered by a yellow bra that was about to slip off.

"Hum...hum...oh...hum..." My sister closed her eyes and called out softly. Her long, soft hair fluttered in the wind, and her pretty face was flushed pink. No one can tell that the innocent sister has lewd behavior. "Oh...oh...don't go in...your tongue..." After hearing the sister's soft cry for mercy, the hateful bald man instead giggled and hugged her hips tightly and pushed forward hard. "Hmm... Hmm... I can't stand it... Oh..." Sister's brows gradually furrowed and her expression became nervous. "Oh...don't...don't do this...hum...I can't stand it...I can't stand it anymore...oh" With a long cry, my sister softly fell towards the bald head, and her long hair covered her face in orgasm again. The innocent sister actually stood with her legs spread and let that old bald man lick her to orgasm. The bald man quickly supported her body, smiled lewdly, freed one hand, and put two fingers into his mouth.

My sister was supported by the bald man around her waist, and she was breathing heavily with her hands on his shoulders. Suddenly, the bald man stretched out two fingers and quickly poked them into my sister's lower body. "...It hurts..." The sudden attack made the sister with loose hair straighten her waist, and her yellow bra fell to the floor.

I stared with wide eyes at my sister's towering breasts, with plump, charming and beautiful curves, and two shaking red grapes blooming on the nipples.

The bald man then cruelly turned his palms back and forth as if he was tightening a screw. I saw my sister looking up with a painful expression, her long legs trembling, and her ten fingers tightly grasping the bald man's shoulders. "Hehehe..." the bald man laughed lewdly.

Seeing the bald guy abusing my sister like this, I really wanted to rush into the house and save her. At this moment, a large amount of crystal liquid came out from between the bald man's fingers. It was my sister's vaginal fluid. "Only I can bring out your sexual desire! Slut, every time I see your big ass I want to fuck you! 'The love juice gushed out like a spring, dripping from the bald man's palm to the floor like honey.

The bald man’s words surprised me. Could it be that my innocent sister is a lewd woman? The bald man's fingers began to move up and down. My sister lifted her right leg and stepped on the bald man's shoulder, allowing the bald man to thrust hard. She faced the ceiling and hummed softly.

"Look!" Your pussy is so tight! "The sound of water came from under the mini skirt. The bald man sometimes inserted his fingers to the root and rotated them a few times before continuing to thrust. Sometimes he seemed to be digging into my sister's vagina, and sometimes he seemed to be stirring it.

My sister's butt in her miniskirt would shake because of the bald man's movements. After the bald man's fingers had been ravaging my sister's lower body for a few minutes, my sister let out another "Gaa" sound, her body fell limply, and she sat on the bald man's left shoulder to rest.

I saw my sister's full ivory-white breasts pressed softly against the bald head. At this time, the bald man pulled out his penis, stood up and held up my sister's buttocks, and a thick but not long penis was inserted into my sister's body.

The bald man was fucking my sister while standing. My sister wrapped her legs around his waist and climbed on top of the bald man as he fucked her.

Because my sister is very tall, her breasts are placed on her bald head and swinging. The narrow skirt was lifted up to reveal her white, wide and round buttocks, and she let out some sad and obscene sounds from her mouth. The sexual fluid continued to drip out from the buttock groove. The sister in the room was being fucked hard by the bald man who held her ass up. Her long, shiny hair was fluttering elastically. After a few seconds, I could still hear my sister's "hmm" moans, as if they were right next to my ear, and I could also smell the scent of her perfume.

I hesitated for a while, and looked up. It turned out that the bald man made my sister lie on the bed with her hands on the bed, and the bald man hugged the beautiful sister's hips tightly to speed up her. I saw that my sister's plump white buttocks were deeply pinched by ten fingers. I could lick the pure and beautiful sister in my mind with just a tongue, but now I had to watch her being raped and enjoyed by the old bald man. While the bald man was doing it, he held my sister's waist with one hand and reached out to the front to knead her big breasts with the other hand. The bald man was raping my sister right in front of me, and in front of me was the ugly penis ravaging my sister's vagina.

The thrusting penis was covered with my sister's body fluids, and the stuffed red and tender vagina was still leaking water. "Ah...ah...ah...ah...it feels so soft...ah...ah...ah...ah...ah..." Hearing my innocent sister moaning, I couldn't help but feel sad. In this mood of grief and anger, I actually developed a contradictory feeling of sexual excitement. I took out my inexplicably hard penis and masturbated while watching my sister being raped by the bald man.

"Ah...ah...oh...I want it...I want it...Oh...Gah...Gah..." My sister screamed twice, and the bald man stopped moving. My sister lay softly on the bald man again, and her vagina, which was tightly combined with the penis, squeezed out a pile of white semen mixed with vaginal fluid. My semen also spurted out impulsively. The bald man pulled out his cock with satisfaction and said to the pockmarked face: "Brother, I am so happy, it's your turn!"

My sister is now naked in front of Ma Lian. Ma Lian's blood must be boiling. I reminded myself in my heart that the best was yet to come! Ma Lian had taken off his briefs, his over-engorged penis was standing upright between his legs, and his two hands were trying to open his sister's legs. My sister's vagina also opened wide. I could only see my sister's breasts and the triangular tuft of pubic hair at the base of her thighs from a distance. I felt an urge in my heart and wanted to rush into the bedroom to touch the tuft of black hair and the warm little hill.

Ma Lian didn't leave me any chance. He had already put his head between Linlin's legs, stuck out his tongue and licked his sister's clitoris. "Oh~" My sister sighed unconsciously and twisted her waist a few times. His sister couldn't stop herself anymore, and he continued working hard between her legs regardless of her reaction.

The sister who was knocked unconscious by the bald man may have lost all feeling. She only felt the itchiness in her lower body and the rapid rise of desire. She began to enjoy the sexual happiness in a half-drunk and half-dream state. The twisting of her waist was getting faster and faster, and she kept raising her hips to welcome the caress of Qi Qiang's tongue. Her little mouth was slightly open, and she let out intermittent moans, "Oh...oh...harder...harder...oh~~oh".

Ma Lian saw that my sister was becoming more and more excited, and he knew that the time had come. He climbed onto the bed and pressed down on my sister's body. From outside, I could clearly see that my sister's breasts were flattening and widening under his weight. Ma Lian's right hand was stretched between his legs. I could imagine that he was holding his hard dick and searching for my sister's flesh hole. After a while, I saw his waist suddenly sink, and I knew he had inserted it. At the same time, my sister let out a loud cry of joy, "Oh..." This proved that my judgment was correct.

At this moment, I was really jealous and horny. While watching his sister lifting her hips and straightening her back as someone else thrusted at her, he couldn't help feeling jealous. He blamed his sister for being too slutty and letting others fuck her without caring who she was. On the other hand, it was also extremely exciting for the first time I saw my sister moaning under someone else. My sister's seductive look and her moans made me very excited. I couldn't bear it any longer, and once again quickly stroked my penis with both hands, but after only a few up and down strokes, an incomparable tingling feeling rushed to my forehead.

"Ah!" I couldn't control myself anymore. I held my breath and let out a low cry. A stream of semen spurted out. I stroked the penis harder. My body arched up due to the smooth and continuous ejaculation. Semen sprayed all over my clothes and hands. This was more comfortable than normal sex.

After ejaculation, I gradually calmed down. But in the bedroom, Ma Lian and my sister were still in high spirits. My sister’s hands were already wrapped around Ma Lian’s waist. The two of them were kissing each other passionately, Ma Lian's waist was arching vigorously, and the stick under him must be going in and out of his sister's vagina. And the sister's slender waist was moving vigorously from side to side, and Fengyu's buttocks was thrusting up and down in coordination with Ma Lian's thrusting.

"Oh...quick~ quick~ baby...oh" As soon as their lips parted, the sister's obscene words came out. “Oh… so… comfortable…. Faster… harder…. Fuck me again… faster…” Ma Lian turned the sister over and fucked her from behind. While doing it, Ma Lian stroked his sister's pubic hair with one hand and reached out with the other hand to knead his sister's big breasts. Ma Lian's fleshy penis penetrated into my sister's vagina deep and shallowly. My sister was no longer moaning, she was crying.

"Okay! I'll fuck... I'll fuck you hard... Your hole is so great... So hot... And so wet... I'm going to fuck myself... Fuck me to heaven!" Ma Lian responded while swinging his hips back and forth rapidly, hitting his sister's pistil deeply again and again, and his sister's hands were now clutching the bed sheets, "Ah~ Yo. ~ Ah. ~ Ah ah. ... Ah~ Good~good... Ah. Ah... Ah~ Fuck... faster... Fuck... me... to death... Ah ah ah...!"

Ma Lian thrusted a few hundred times more, he might have reached the edge of heaven “Wuwu… I~ I’m about to cum… cum…!” “… cum. Cum~ It’s… It’s okay… cum… inside… ahhhh…”

My sister seemed unable to bear his rapid and fierce attack, and her body began to tremble violently. After Ma Lian thrust hard into the center of my sister's flower, his whole body froze on her, his hands tightly grasping Linlin's shoulders. I knew he was ejaculating, and his glans was ejecting thick white semen, which was rushing into my sister's vagina and uterus.

After they had sex with my sister, the two of them slipped away. I tiptoed to my sister's bed and saw her lying naked. The towering breasts and the sexy pussy were in front of me. I called her softly a few times at first, but she seemed like dead and didn't respond at all. I felt relieved now, but I still shook her body to be on the safe side, hey! I couldn't bear it anymore and continued to rape my sister.

I first caressed my sister's breasts. She was completely unconscious at this time and let me rape her. Then I put my other hand into my sister's inner thigh and slowly slid up to her vagina. In an instant, I froze, and at that moment I lost control again. My dick had already raised its head as if begging me for something. At this time, I continued to rape my sister. I used my fingers to dig into my sister's vagina, and the other hand was not idle either, continuing to rub my sister's breasts. I got excited and rubbed my whole face between her breasts, enjoying my sister's unique girlish body fragrance. While I was rubbing and pinching my sister's breasts with my hands, I was sucking, biting, circling and licking her small nipples with my mouth. In an instant, I suddenly felt that my dick needed to be fed by my sister's vagina.

Originally in my rape plan, I had no intention of inserting my penis into my sister's vagina. I just wanted to see my sister naked and caress her proud breasts and her vagina. But now I could no longer control myself, so I once again mustered up the courage to break through my inner limits, took out my shiny, swollen penis, and inserted it into my sister's vagina in one go.

As I was thrusting in and out, I spit out my saliva, which I learned from watching porn movies. My sister's vagina was slowly filled with my saliva and became very lubricated. At this time, I felt like I was in heaven, it was so hot, I felt my sister's vagina getting hotter and hotter, and suddenly I found that vaginal fluid was flowing out of her vagina. I didn't understand why at the time, but I didn't think much about it. I took the opportunity to ejaculate my thick virgin sperm, and I seemed to be in shock. I lay on my sister's chest, shouting at her nipples, and I didn't get up until about ten minutes later.
