The sun near noon shone on the corridor outside the classroom. The stuffy feeling unique to humid summer days continued to evaporate. Although there was cool air from the central air-conditioning in the classroom, all the girls in the classroom were covered in sweat. The white uniform shirt, which was as thin as a cicada's wing, was completely unable to cover the adolescent breasts, whose average size was more than an O cup. The white and tender southern hemisphere, plus the tall northern hemisphere that was unable to be covered by the wet shirt, were all displayed in front of Liu Feng's eyes.
The classroom was filled with the unique feminine odor of high school girls in adolescence - a faint sour smell of sweat mixed with strong and stimulating female hormones, as sweet as slightly fermented yogurt. In this classroom full of sweet and sour aroma, Liu Feng learned how to tell whether girls were in their menstrual period or ovulation period by the feminine scent emanating from their pussies in just one morning.
However, you can also judge by the underwear the girls wear: if there are faint blood stains and sticky love fluid on the underwear, it means that the female is in estrus during her menstrual period, and if there is light yellow mucus oozing out from under the plump and tender vagina, which may be accompanied by a few transparent and elastic eggs like citrine, it means that the female in the ovulation period can't help but stimulate ovulation.
This erotic distinction kept tempting Liu Feng to squat behind each girl's buttocks to observe and sniff carefully during class. The class naturally ended with the girls' gasps one after another stimulated by Liu Feng's breath. When the bell rang, Liu Feng sat in his seat at the end of the classroom on time, savoring the different smell of estrus of each girl.
"Brother, what a fool! He crawled under my chair during class and kept sniffing my pussy. I almost couldn't hold it back. He knew I was ovulating... but he got so close to me. The smell from his nose almost made me orgasm~" Ranran walked to Liufeng and kept complaining.
By the way, Article 6 of the current code of conduct of the school rules stipulates that all girls who take classes indoors must squeeze their buttocks as far as possible into the gap between the chair back and the seat and fully expose their vagina and anus so that the master can easily check and penetrate them at any time.
This school rule, which was completely formulated by Liufeng, has greatly facilitated the advancement of the work of all Liufeng staff without responsibility.
"Yeah, among the 20 females in the class, 10 are in their menstrual period and 8 are in their ovulation period, yeah~" Liu Feng closed his eyes and nodded proudly, completely ignoring the angry Ranran and just analyzing on his own.
"Of course... I also sniffed out a little bitch who was in heat because her menstrual period and ovulation period completely overlapped..." Liu Feng said, pointing his finger at Ranran, whose face had already turned red in front of him, "It's you, Ranran!!"
"Ahhh, don't say such things even if you know! Stupid brother!!!" Ranran's face flushed as she pulled down her skirt and tried her best to cover her flooded cunt. Although the skirt was so short that Ranran's efforts were completely useless, thin and sticky threads of love kept gushing out of her cunt, forming a small pool of water under Ranran's feet.
"Ranran's pussy is really easy to understand. The slight fishy smell of menstrual blood and the strong stench of female hormones made me guess it at once." Liu Feng said as he grabbed Ranran's butt with his strong arms, his fingers sinking deep into the soft buttocks. Liu Feng put his nose in front of his sister's pussy and gently blew a breath of hot air.
"Ah... don't... don't stimulate my little pussy which is in ovulation period~, I'm... I'm going to come..." Ranran pushed Liufeng's head with all her strength but her body kept spasming. It was obvious that she had reached a shameful climax just because of Liufeng's breath!
❤❤
Liu Feng did not give Ranran a chance to rest. He pressed his tongue against Ranran's slightly erect and rosy clitoris. With the lubrication of the constantly flowing love juice, he intensified his attack, and his flexible tongue licked around the little bean wantonly.
"No❤... Little Bean, you can't... Haah~❤ No... Don't stimulate me anymore. Master brother's little bitch is going to... is going to... is going to have an ovulation orgasm~ Ahhhh hahhhhhhhh!!!!❤❤❤❤" Ranran suddenly raised her slender waist in the repeated climaxes. Her pink hair fluttered in the air with her shaking body. Only the sound of "hiss... puff... puff~" could be heard coming from the little hole that was in orgasm and ovulation. Liufeng hurriedly placed his left hand gently on the back of Ranran's hole and his right hand successfully penetrated into the soft back hole and stimulated the tight G-spot inside the hole through the flesh wall.
The intense double stimulation from the front and back caused Ranran's beautiful buttocks to surge with waves of flesh. The fingers in the anus were pushed out by the tight pressure generated by the orgasm in the intestines, bringing out streams of sticky intestinal fluid. Liufeng only felt a warmth spreading on his hands, and soon it overflowed and flowed down his arms.
Ranran was enjoying the tingling ovulation climax to her heart's content. Her brain had already become so comfortable that she unconsciously gave up control of her whole body. She broke away from Liufeng's arms and collapsed on the floor covered with vaginal fluid, revealing her white belly in front of her. Like a submissive bitch, Ranran weakly lifted her legs and continued to squirt vaginal fluid. Her huge breasts, like milk puddings, were spasming and shaking with the afterglow of the climax. Her pink nipples were not to be outdone and tried hard to break through the restraints of the school uniform.
Liu Feng's hands were filled with amber-yellow mucus, in which were floating several transparent female eggs the size of soybeans.
The faint smell of obscenity stimulated Liu Feng's nerves. Without waiting for his brain to react, Liu Feng poured the obscene fluid in his hand into his mouth. The smooth mucus went down his throat and tasted like green milk tea. The touch of each female egg was as chewy and delicious as the pearls in the milk tea.
The love fluid produced in this erotic girl's body has a strong aphrodisiac effect on Liu Feng. The meat rod under his crotch has pushed out a towering hill in his uniform pants. The fully erect big meat rod even makes Liu Feng feel that his underwear is being squeezed into the crack of his buttocks.
Liufeng turned over Ranran, who was lying powerlessly on the ground, and unbuttoned his pants with difficulty. The thick cock broke through the restriction of the underwear and popped out. The penis, as long as Ranran's forearm, was suddenly clamped in the valley formed by the milky white buttocks. Liufeng only felt that his cock was pressed tightly in the buttocks. With the lubrication of the mixture of intestinal fluid and love fluid, the cock began to thrust violently. The swollen lower end of the urethra was constantly stimulated by the soft labia and the pink folds of the anus. The huge jade bag hit the buttocks roughly, making Ranran, who was lying on her huge breasts, shake violently back and forth.
"❤Mmm~❤, brother's big cock rubs the bitch Ranran's pussy so comfortably~"
Ranran moaned and pressed her anus tightly against the giant cock. Her labia, like an outward-spreading flower bud, clamped tightly around Liufeng's penis, stimulating it as if to squeeze out semen.
"Brother's movements are so intense~❤ Are you going to use my butt as a vagina and fill it up with your sperm? If your stinky brother's sperm goes in, my butt will get pregnant too!!!❤"
"Since you know you are a bitch, you should know how to serve your master! Moan in horny way for me!" Liu Feng raised his hand and slapped Ranran's buttocks, leaving a deep red palm print.
Liu Feng tightened his waist and pushed his giant penis along the smooth buttocks to the slightly open vagina. Then, he used all his strength to insert the red glans straight into Ranran's heart. Under the heavy pressure, the cervix gave up resistance and tightly locked the coronal sulcus under the swollen giant penis.
"Ohhhhhh!!!❤❤❤Bitch Ranran is about to be pierced, her uterus...her uterus is going to completely turn into the shape of brother's majestic big cock, well, woof~❤" Ranran made a charming and weak dog barking sound in her endless female orgasm.
Liu Feng swung his waist and penetrated Ranran's soft little flesh again and again. The love juice kept flowing out from the point of connection, and splashed all over the ground along with the huge testicles that kept swinging back and forth and hitting the buttocks.
The soft flesh inside the hole wrapped tightly around the penis as if it had life, and it even sucked Liu Feng's balls in, entangled with it fiercely.
With the last firm impact of the jade bag, nearly 2 liters of semen stored in the seminal vesicles all poured into the fully expanded urethra. With a burst of supreme pleasure rushing straight into Liufeng's brain, the thick white liquid broke through the restraint of the glans and rushed straight into Ranran's uterus. The repeated contraction of the urethral muscles and the long ejaculation made the jade bag shrink around the root of the flesh to reduce the distance between the sperm and the egg.
The sperm sac, as big as the largest apple, continuously produces the master's sperm specially for the bitch Ranran to inseminate.
Soon, Ranran's bulging belly lifted her delicate body up. The five-minute ejaculation made Liufeng feel extremely refreshed. The feeling of the opening of the jade bag as all the sperm rushed out made his waist tremble. The feeling of the prolonged ejaculation was like a long female orgasm and an intense male orgasm superimposed on each other. Every contraction of the urethra during ejaculation made Liufeng moan like a girl's squirting. All the sperm was shot into the bitch sister's famous vagina.
When Liu Feng pulled out the penis that was inserted in the vagina, the hot white liquid poured out like a broken faucet and formed a pool of semen on the floor.
"Oh oh oh ~❤ Bitch Ranran is cumming too, her pussy feels as soft as when I ejaculate!!❤❤ Cumming ~❤ ❤" Ranran's eyes rolled up and her sweet tongue slid to the corner of her mouth, she was drooling.
With a "puff" sound, a stream of golden liquid spurted out of Ranran's urethra, drawing a perfect arc in the air and pouring onto the penis that was still spurting semen. The warm and moist feeling instantly spread throughout the entire penis, and under the wrapping of the urine full of estrus, the penis also violently ejected more and thicker white liquid, staining Ranran's jade legs and breasts with white semen with a seafood smell.
Liu Feng stroked his still powerful cock, straddled Ranran's slender waist and pulled up her two rosy nipples with one hand, causing Ranran to let out a coquettish cry of "Ah~❤️".
He gently thrust his waist and his penis slid into the two soft breasts without any hindrance. Ranran squeezed the breasts hard with both hands, squeezing them into the shape of a breast hole that would make her brother most comfortable.
"Ahhhh~❤Brother is so awesome! Ranran's nipple was also roughly raped by brother! In order to reward brother who made Ranran so comfortable, I will give this hard-working big cock some benefits~❤"
Ranran looked at the round glans that kept shrinking and growing in front of her, and her rationality was overwhelmed again.
She stuck out her tongue and gently blocked the open glans. As the penis thrust in and out, her tongue kept moving in and out of Liufeng's urethra. A tingling pleasure spread throughout Liufeng's body.
"You are such an unsatisfied little slut, ahhhh!!! I'm going to fill your stomach with my master's semen!!!" Liu Feng said as he increased the speed of thrusting, his soft breast flesh tightly wrapped around the stem, his warm and fragrant lips sucked the front end of the glans like a vacuum, and his small tongue did not forget to gently thrust in the urethra.
The triple extreme stimulation brought Liu Feng a feeling of pleasure as if his penis was raped by Ranran's nipple and tongue in her urethra. Another stream of freshly-eated hot sperm rushed into his urethra.
Under Ranran's urethral reverse rape, the thick semen in the penis violently hit Ranran's sweet tongue. The semen kept wandering back and forth, wanting to rush into Ranran's mouth but was ruthlessly trapped.
"Ahhh!! I'm going to cum. I'm going to shoot all the fresh sperm I just made into this bitch's mouth!!!" Liu Feng pushed his cock into Ranran's mouth with all his strength. As Ranran's tongue relaxed, a stream of sperm with a strong masculine smell spurted out and instantly filled Ranran's mouth. Liu Feng rested his body on Ranran's beautiful face with his soft breasts and ejected all his sperm into her tightened esophagus. Although the second shot was not as long-lasting as the last time, it was extremely intense and even gave him 10 times the pleasure. The throbbing cock propped up a small hill in Ranran's throat and he ejaculated into her mouth wantonly.
After the semen was completely ejaculated, Ranran's lower abdomen was already the size of a small watermelon.
"Suck it~❤Brother's big cock is so powerful~It fills up Ranran's bitch pussy from top to bottom~❤"
Ranran wiped the sperm from the corner of her mouth and rolled it into her stomach with her tongue. She then gave a deep kiss to the still throbbing penis and winked at Liufeng.
"Burp❤, I'm so full of sperm, this time I can have full energy for physical education class~❤" Ranran said playfully, and burped lightly with a sweet smell of male sperm, revealing an adorable smile...
Liu Feng sat down on the floor, panting heavily. After being drained of semen by the bitch sister, he didn't feel tired at all. He only felt the comfort of the empty balls.
Suddenly, there was a crisp knock at the door. Liu Feng looked up and saw a black-skinned girl with short orange hair falling in from the half-open door.
"Ah...hiss, it hurts, it hurts..." Liu Feng looked carefully and found that it was teacher Cai Chen who was conducting the entrance inspection at the school gate this morning. There was a towering hill under her tight black sports underwear, and the outline of the swollen glans of the erect female root was also outlined by the tightly wrapped underwear. The glans was obviously filled with sperm that swelled like a water balloon after the masturbation climax, and it swayed as Cai Chen's body fell.
"Cai... Teacher Cai Chen?" Liu Feng looked at Cai Chen in front of him with surprise. He actually felt a trace of shyness he had never felt before. He subconsciously used his hand to cover his still erect penis.
"Why are you here?"
"I know! Teacher Caichen must be peeking at my brother and I having sex!" Ranran, who was lying on the ground just now, suddenly became excited and smiled evilly like a little devil. "She must have been unable to resist after seeing my brother using his big cock to fuck me~"
"How...how is this possible? I...I'm a teacher at school. I wouldn't get in heat just because I see you two..." Cai Chen rubbed her messy orange hair nervously. A few beads of cold sweat suddenly broke out on her wheat-colored body. The sweat flowed along her slightly exposed abdominal muscles and into her sexy belly button. Her right hand tried her best to suppress the still pulsating female root under her crotch. An awkward smile appeared on her face, and her small sharp fangs were unconsciously exposed, like a child who was caught doing something bad.
"Eh? Really? What's up with that thing under your crotch?" Ran Ran said as she gently lifted up Cai Chen's swollen female balls with her hands and put her mouth next to her ear and moaned softly, "You're not getting aroused by watching your brother fucking my teacher's little female hole, are you also wanting your brother's hard cock to penetrate it, Teacher Cai Chen?"
"Ah~ No... No!" Cai Chen was so shocked by Ranran's sudden attack that she gasped softly like a virgin, but her red face immediately turned serious. "Ye Liuran! You and Liufeng, hurry to the playground for class. The whole class has been waiting for you for a long time!"
"Hehe~" Ranran's delicate face showed a look of success. She bit Caichen's ear lightly and whispered, "Remember to come to the sports warehouse after class~ Teacher Caichen is in heat~"
Without waiting for Caichen to react, Ranran dragged the disheveled Liufeng behind him and ran out of the classroom.
"Ranran! Don't run so fast! My pants! I haven't pulled them up yet!"
"Hmph, stupid brother~ No one will say anything to you even if you show your big dick to class, so go away~"
After the brother and sister left, the corridor became silent in an instant. Only Cai Chen was left standing there, covering her mouth with her hands to prevent herself from making any noises of ejaculation. She was trembling violently. Ranran's obscene words stimulated her to orgasm and ejaculated. Streams of soft and hot female essence flowed into the large condom worn on Ji Ji under her tight sports pants like fountains. The swollen condom filled Cai Chen's buttocks, which were flooded with her own vaginal fluid...
