Sister swap in the bathroom (student campus adult novel)

Sister swap in the bathroom

Tomorrow is New Year's Day. The school is holding an all-night New Year's Day dance party tonight. As soon as the get out of class is over, I went to my girlfriend's house.

My girlfriend Xiaofan went to work in a wholly foreign-owned enterprise after graduating from high school. I met her at a school dance.

Xiaofan is the second child. Her elder sister Xiaosu and Xiaofan work in the same company. Xiaosu is an accountant and Xiaofan is in sales. My younger sister Xiaoting is still in secondary technical school. I introduced her to my boyfriend, who was my classmate in college. His name is Agui and he is my best friend.

It is now 5:30 in the afternoon. Xiaofan has returned home, changed into pajamas, and is helping her mother-in-law wash vegetables and cook. The food in school is not good, so my mother-in-law feels sorry for me and asks me to come over for dinner from time to time. Today is New Year's Eve, and I came without being asked.

"Xiao Fan, do you need my help?" I stood at the kitchen door and said to her with a smile.

"You stupid guy, what activities are there at school tonight?" Xiaofan looked back at me, then lowered her head to continue washing the vegetables.

She was wearing a sleeveless white shirt with wide cuffs that revealed her private parts. Her breasts were faintly visible, and her beautiful butt was sticking out nicely, making her panties clearly visible.

I felt my desire slowly burning and my cock was getting active.

"Oh, the school is holding an all-night dance, we can dance all night long." After saying this, I realized I had said something wrong because my mother-in-law was here.

"Yes, New Year's Day should be celebrated well, as you are one year older." I didn't expect my mother-in-law to be so understanding.

"Go take a shower quickly, you're so dirty." Xiaofan rolled her eyes at me.

I left dejectedly and went down to the second floor.

Xiaofan's family lives on the third floor and does not have a separate bathroom. Not long ago, her father-in-law asked for a two-bedroom apartment from the school and converted the kitchen into a bathroom, so that taking a bath in winter is no longer a problem.

I opened the door with my key and found that the curtains in the bathroom were drawn. There was the sound of water splashing outside and a man's voice.

"It feels so good. Lick the testicles. Yes, the bottom. Go down further and lick the anus too."

I listened. What a familiar voice. Agui, it’s this kid. No wonder I couldn’t find him after class. It turns out he was enjoying himself here.

The girl who gave him a blowjob must be Xiaoting. Xiaoting is the most beautiful and has the best figure among the three sisters. I dream of peeping at her naked body. Unexpectedly, after searching for her in my dreams for thousands of times, I finally got her without any effort.

My cock has become very hard in anticipation of the erotic scene that is about to unfold.

I walked to the bathroom door and looked through the gap in the hanging door curtain. The bathroom was filled with steam. Agui was standing under the shower with a huge cock sticking out his head.

Agui has the biggest dick in our class. We guys always compare with each other to see whose is the biggest. Agui always takes first place, because his dick is not only long but also thick.

Under his penis, there was a young girl squatting. Needless to say, it was Xiaoting.

Xiaoting had her back to me, with her long hair draped over her smooth back. I couldn't see her front, which made me so anxious that I kept stamping my feet. I saw Xiaoting sticking out her tongue and licking Agui's balls carefully, with the cock resting on her beautiful face. Xiaoting's figure was indeed good, a standard inverted guitar shape, with her plump buttocks wide open.

I pulled open the door curtain, Agui saw me at a glance and almost screamed. I quickly made a gesture to silence him. He looked at me in surprise. I pointed at Xiaoting and made a gesture of drilling a hole. Agui shook his head to show his disagreement. I didn't care about him and started to take off my clothes, pants, and shorts in front of him until I was completely naked. I gestured to Agui, meaning for him to start fucking Xiaoting.

Agui could no longer bear Xiaoting's licking. He pulled Xiaoting up, lifted one of her legs, squatted slightly on his knees, pressed his erect penis against her vulva, and rubbed the glans against Xiaoting's labia. Xiaoting wrapped her arms around Agui's neck, and swayed her butt from side to side, obviously also overwhelmed by sexual desire.

Agui pushed upwards, and the glans pushed open the labia and sank into the vaginal opening. Agui's penis was too big, and Xiaoting seemed unable to bear it. She kept lifting her toes upwards. Agui withdrew a few inches, then pushed forward a few inches, back and forth several times, and finally the entire penis was inserted into Xiaoting's body. A hairy scrotum hung under Xiaoting's vulva, her buttocks were stretched wide open, and the light brown anus was clearly visible.

Agui began to twitch with difficulty. This posture was indeed a bit difficult. I signaled Agui to hold Xiaoting. Agui's twitching was small, so he had to lift Xiaoting's legs and hold her to his chest. Using inertia, his buttocks hit Xiaoting's vagina back and forth.

"Ah...ah..." Xiaoting moaned.

I walked in with my dick erect, stood behind Xiaoting, squatted down, stuck out my tongue and started licking Xiaoting's anus. Xiaoting began to feel something was wrong as the tip of her tongue moved and her anus felt itchy. She turned around and found that it was me. Her face turned red and she began to struggle all over.

Agui thrust more violently at this moment. The waves of pleasure diluted Xiaoting's shyness, and the itchiness in her anus made her bolder.

"You, okay, I will definitely... tell my sister that I will not forgive you." Xiaoting panted and moaned.

I didn't answer her and continued to lick her anus. The anus became red and slightly open after being licked by me. The pleasure of the two holes in front and back made Xiaoting reach her first orgasm quickly.

I stood up, put some soap on my hand, applied it on Xiaoting's anus, and also put some on the glans. I held the penis in my hand, let the glans press against the anus, and slowly pushed it into the narrow anus.

"No, no, it hurts..."

Xiaoting panicked and twisted her body violently, but she was tightly clamped by Agui and me and could not move. At this time, the penis was tightly stuffed in the rectum, and half of it remained outside. I was sweating all over. It was so fucking tight that I could not move forward or backward. I winked at Agui and asked him to continue thrusting. The pain in the anus and the pleasure in the vagina intertwined together, making Xiaoting feel like she was dying of ecstasy.

Two cocks were inserted into Xiaoting's body at the same time, separated by only a thin layer of flesh. The heat from the cock next to me was transmitted to me. I felt Xiaoting's anus gradually relax and was not as tight as before. I touched Xiaoting's chest, found the soft breasts, and began to rub them.

She is young and elastic, after all, she is only 17 years old. Her breasts are one size bigger than Xiaofan's. I ravaged Xiaoting's tender breasts like kneading dough. My cock began to twitch slowly, with a small amplitude at first, and gradually increased the amplitude and frequency as the anus was lubricated. Agui and I moved in and out in tacit understanding, making Xiaoting scream "ah, ah". The temperature in the bathroom seemed to be getting higher and higher, and the three of us were sweating all over.

Just as we were immersed in the sea of ​​sexual desire and were about to enjoy the ultimate bliss, Xiaofan's voice suddenly came from outside the door.

"Zhipeng, are you done washing? Hurry up, I want to wash too."

The three of us were shocked, and my mind went blank. I didn't know what to do.

Ah Gui was indeed surprised at this time, and he whispered to me, "Let her in, the four of us..."

I understand what he means. I slept with his girlfriend, so of course he wants to enjoy my little fan too.

I was on the verge of orgasm when Xiaofan poured a basin of cold water on me. I was so horny that I had to let it out.

"It's almost done. I'll open the door for you." I pulled the cock out of my anus, walked out of the bathroom, and opened the door while covering my naked body.

Xiaofan walked in and saw my naked body and my erect cock. Her face turned red immediately and I quickly locked the door.

"So you masturbate while washing. You have no shame."

"Okay Xiaofan, let's take a shower together. I'm already in this state, please have pity on me."

“You deserve it!”

Having said that, Xiaofan has already started taking off her clothes. I saw her take off all her clothes in no time. Xiaofan looked at me shyly and rushed into the bathroom, and I followed her.

"Ah!" Xiao Fan covered her mouth in shock.

I saw Xiaoting holding the wall with both hands, bending over 90 degrees, opening her legs, and inserting a huge rod in her vagina. As Agui rhythmically hit Xiaoting's plump buttocks, her big breasts swayed back and forth.

Xiaoting shyly turned her head to look at her sister, and Agui also stared at Xiaofan's naked body.

"Sister, they... no, Agui makes me feel so good..." Xiaoting said breathlessly.

Xiaofan was so surprised that she couldn't speak and just stood there in a daze.

I seized the opportunity to get behind her, caressing her beautiful breasts with one hand and attacking her vagina with the other. Looking at the spring scene in front of her, and the pleasure coming from the two most important places on her body, Xiao Fan was also infected by the lustful atmosphere in the bathroom, and her mouth began to "hmm".

I turned Xiaofan's body around, held her shoulders and pushed her down. She understood what I meant and took my dick into her mouth and started to give me a blowjob with her head moving forward and backward.

I looked at Xiaoting's vagina being fucked, her breasts swaying, and the cock continuing to swell in Xiaofan's mouth.

While Agui was fucking Xiaoting, he was enjoying Xiaofan's oral performance. We both smiled knowingly and enjoyed the beauty in front of us.

I thought it was almost time, so I pulled Xiaofan up and made her do the same position as Xiaoting. I pressed down Xiaofan's waist with one hand, protruding her buttocks, and grabbed the penis with the other hand. The glans found the moist hole and slowly inserted it. We both screamed at the same time, and then I started to perform the most primitive action of human beings.

Agui and I seemed to be competing as we fucked the sisters in front of us hard. The "pa pa" sound of our sexual organs joining together, the "hmm" moans during intercourse, and the "swish" sound of water spraying from the sprinkler all intertwined together to play the New Year's music.

Agui made an exchange gesture to me. This guy wanted to take advantage of Xiaofan, but I really wanted to fuck Xiaoting's pussy and asshole, so I had no choice but to agree.

I pulled out my cock, and Xiaofan felt empty all of a sudden. I gestured to her to do the doggy style. Although Xiaofan was reluctant to do such an embarrassing posture, she was so aroused by the sexual desire that she had to do it. I also knelt down and inserted my cock from behind Xiaofan's ass. At this time, Agui pulled out of Xiaoting, came to Xiaofan, grabbed her hair, and forced her to suck my cock.

The two of us fucked Xiaofan hard, one from the head and the other from the back, and she could only make a "wuwu" sound in her throat. I pulled Xiaoting over, inserted three fingers into her vagina with one hand, and inserted the index finger of the other hand into her anus. I used all the weapons in my body at once to fuck three enchanting little holes.

After thrusting for a while, Agui waved his hands at me. It seemed that he was about to ejaculate. I quickly pulled out my cock and gave Xiaofan's hole to her. I turned Xiaoting over, pressed on her body, held the cock in my hand, and inserted it into the pussy that had already been flooded. Hum, it was a little loose after being penetrated by Agui, but it didn't matter, fortunately I still had the asshole.

I saw Agui come behind Xiaofan, and thrust all the way in without any hesitation. He pressed Xiaofan's butt with both hands, and rammed Xiaofan violently. He also hinted to me that he was satisfied with Xiaofan's hole.

This aroused my urge to ravage Xiaoting, so I pulled out my penis and put the glans against the anus. Xiaoting noticed my intention and hurriedly twisted her buttocks, trying to get rid of it. I pressed down hard and pushed my body forward, and the entire penis penetrated her and was tightly wrapped by the rectum. I pressed my fingers on the clitoris above the vagina and rubbed it continuously to reduce the pain in Xiaoting's anus. After a while, I began to thrust slowly. Because the anus was too tight and the previous accumulation, I finally couldn't bear it anymore and spurted a large amount of semen into the rectum.

It’s so hot…, so comfortable, I’m almost dead…ah, ah…” Xiaoting and I screamed at the same time and reached the highest point.

"Oh......" At this time, Agui and Xiaofan were heard moaning loudly at the same time, and it seemed that they had also ejaculated.

"It's time for dinner. Mom and Dad are waiting." Xiao Su's voice came from outside the door.

The four of us quickly got up, scrambled to wash the remains off our bodies, and played around with each other. It seemed that the two sisters had tolerated the incest between us.

Agui and I smiled at each other and looked forward to the happy days in the future. The second New Year's Eve of the new century should be the beginning of our good times.
