Mianmian packed her schoolbag and walked to the office building.

    It was only after entering the building that she realized that it was quiet inside, with no one visible until the fifth floor.

    Just as she was about to go downstairs, she heard a familiar scream.

    “Don’t…”

    ——It’s Ruan Ruan!

    Mianmian stopped immediately, thought for a few seconds, and walked silently to the end of the corridor.

    The sound came from an office. The office door was locked and the curtains were drawn, leaving only a small gap.

    Mianmian crouched down and quietly looked inside…

    At this sight, her eyes suddenly widened.

    Bright office interior.

    Her deskmate and friend was lying on the desk at the moment, her navy blue school skirt was lifted up to her waist, and her snow-white buttocks was exposed to the air. Behind her, a man pinched the girl’s waist and pressed hard. He straightened his waist, and the genitals under his crotch slid in and out of the girl’s legs. You could tell what he was doing at a glance!

    Mianmian could even see the wet cunt sucking the shaft of the rod, going in and out, and a mixture of white and transparent liquid dripping from the joint between the two.

    Isn’t this a substitute teacher?

    Mianmian’s heart was trembling, but she didn’t dare to make any sound.

    Inside, Zhou Ruan was still shouting, with a hint of hoarseness and unknowing flirtation, and she was scolding extremely harshly.

    “…Yin Zhou…you beast…get out…get away…ah…”

    However, when he heard the girl’s voice, the man not only did not stop, but became even more excited. He raised his big hand and slapped the girl hard. There was a crackling sound on the buttocks.

    “Ruan Ruan, why don’t you call me brother… Hmm… your little cunt is tight… Wasn’t it just last night that the old man fucked you… Why… dad didn’t fuck you well?… The old man didn’t have the strength to fuck you, so I came here…”

    Teacher Yin’s words shocked Mianmian, and then she heard her friend scolding her again.

    “…Don’t mention him…you don’t deserve to compare with him…ah…take it out quickly…your enoki mushroom…is not half as long as dad’s…short and thin…ahhhhhhhhhhh…you’re fucking me so hard…you’re fucking my uterus…come on…get out of my pussy…are you an animal…”

    The girl’s biased words clearly angered the man. The man who was usually a flower on the mountain completely disappeared at this moment. His forehead was messy, his hair was messy, and he was pressing the person underneath him. It was just a collision, and the thick shaft was densely and crazily inserted into the tender pussy, fucking the girl until she moaned and cursed again.

    For a moment, Mianmian didn’t know whether to be shocked or amazed at the chaotic relationship between Ruan Ruan, the teacher, and the teacher’s father, or how her petite body could withstand such fucking.

    But soon, Mianmian’s thoughts were disrupted again.

    The little girl poked her head again and found that the person inside had changed his position. Zhou Ruan was turned over and lying on her back on the desk. Her school uniform top was lifted up to her neck. There was a sexy bra underneath, exposing her huge breasts. On the outside, the small piece of fabric can only cover both areolas.

    Not only was Mianmian dumbfounded, but Teacher Yin was also obviously confused, followed by undisguised ridicule.

    “Are you dressed like this so you can seduce dad?”

    From Mianmian’s angle, you could just see Ruan Ruan being forced to open her thighs.

    The girl’s legs were arranged in an M shape, and her black leather shoes were placed on the table. At the center of her open legs, her red pussy was deeply penetrated by the man’s huge dick, and his huge and full sac just blocked the buttocks below.

    With a gentle push from the man, the fabric on the girl’s chest quickly slipped off, and her snow-white breasts were completely exposed to the fluorescent light. The two areolas were dark pink, and her nipples were twice as big as those of ordinary people, and they were not even erect.

    So big – even Mianmian was amazed, let alone Teacher Yin from close range.

    “Tsk… It’s just like breastfeeding. When you first came to my house, you were still flat-chested. Why did dad rub it so big?” The man started to grab and rub the nipple rudely, twisting the erect nipple between his slender fingers.

    Zhou Ruan couldn’t help but hum, and sarcastically said: “Yes, dad rubs and sucks them every day… Ah… I have breastfed him since the second grade of junior high school… and I have sex with him every day… …Daddy’s cock is so big…it feels so good to fuck…and his cum tastes so good…You don’t know…I give him blowjobs every morning…”

    “Fuck! Shut up, you slutty bitch, you’re so young. Seduced my dad, I’ll fuck you to death!”

    The man became angrier as he listened, grabbing the girl’s leg and thrusting again.

    “…Try harder…Yin Zhou…you move like you haven’t eaten…Uh-huh… I know so much… Shouldn’t you call me… Mom…”

    “Shut up! “

    The man’s voice was suppressed with anger. He was angry and sad in his heart. He bit the girl’s lip to prevent her from speaking. He thought that thrusting into her once would be the limit, but he didn’t expect that the girl who had been secretly in love with him for several years had been with his father since she entered the house. With the first and last, they carried on their relationship behind his back for so many years and had sex every day under the same roof.

    And when he went abroad, the two of them must have had sex at home without any scruples. When he thought about it, they had sex everywhere he looked. The man’s heart was bleeding, and he wished he could go back to a few years ago and fuck her to death.
