A sinful relationship

Mary stood in front of the large floor mirror, completely naked and looking at her body. She had just turned eighteen. She was preparing to graduate from high school this year and to celebrate, she was going to the prom. But she couldn't go alone. Even though there was still plenty of time left, Mary was nervous because all her friends had already been invited. She was the youngest in her class and had recently stopped wearing braces. She was short and chubby like her mom. Mary had firm, erect breasts with round, pea-like nipples, a swollen tummy, and a fluffy, dark pubis that she loved to stroke at bedtime. The girl thought that her ass was too voluminous, and her legs were short and fat, so she was in a prolonged depression. She decided to amuse herself in a well-known way. She lay on the bed and looked in the mirror at her slit. Spreading her legs, she stroked herself on the inside of her thighs, running her finger over the wet curls and penetrating inside.

She found her clit and began to irritate it, stroking and pulling on it. She cum quickly, but it gave her no pleasure. Pulling a huge pink dildo out of the bedside table drawer, she looked at it with some doubt, then generously smeared it with Vaseline and arched up and inserted it into her scarlet rubbed hole. His vagina greedily swallowed the treat. Mary had taken her innocence four years ago, so the big rubber dick entered her slit full length with no problem. The girl's vagina was tight, hot and wet. Her juices soaked the bed beneath her, lubricated the dildo perfectly, and she didn't feel the slightest pain. It wasn't very comfortable fucking herself, but Mary did her best. She sniffled and moaned heavily until she finally reached orgasm. She collapsed exhaustedly on the pillows, leaving the rubber baton sticking out between her thighs.

As he passed his daughter's room, Seth heard her moans. Wise from experience, he had no doubt his daughter was masturbating, certain she was alone in the house. The door to her bedroom was ajar. What he saw shocked him: his clever little daughter was fucking herself with a long, thick aggregate that fully entered her relaxed raw hole. He and his wife were sure that Mary was still a virgin, since not only had she never brought guys home, but she had never told them about them. So the racy orgy in their daughter's bedroom surprised Seth. Mary was good looking, her naked body glistening with sweat. Against his will, Seth's pants tensed. Lowering his hand, he squeezed the heavy lump in his groin, eager to insert Mary and cum in her hole. But something held him back. He slipped his hand under his underpants and began to jerk off. Meanwhile, Mary had come to her senses. She pulled the slime-covered dick out of her juicy cunt, licked it, and, throwing her legs over his shoulders, began rubbing the blunt, smooth head of his ass hole. Seth nearly died of arousal. He watched his daughter fuck herself in the ass and felt himself cumming.

His cum flowed into the palm of his hand, flooding his groin and briefs. But Seth wasn't satisfied. He quietly opened the door and walked into his daughter's room. Mary was so busy pressing the rubber dick into her little asshole that she didn't immediately notice her father. Finally she looked up, shrieked and blushed.

- It's not working? - Seth asked calmly. Mary shook her head negatively. Her father took the dick from her hands and said:

- Get on your knees and bend over.

Mary obeyed. Seth noticed how longingly she stared at his shriveled, powerless penis sticking out of his unzipped fly and smirked. He sat down on the bed at her feet, stroked her naked fat ass and spread her buttocks. The round brown hole, lubricated with Mary's saliva and wetness, squeezed slightly under his gaze. Taking Vaseline, Seth lubricated his finger and inserted it into his daughter's tight anus. He stroked her rectum from the inside until the girl relaxed. Her ass lowered slightly and Seth began to insert the rubber monster into her virgin ass. No doubt Mary was in terrible pain, but soon something inside shivered and she breathed a sigh of relief. The dick entered her fully, but it was too big for her undeveloped passage for Seth to move freely through it. So he pulled out the imitator and inserted his own still raw cock into his daughter's asshole. This felt much better and Seth began fucking his daughter. Mary frantically swiveled her hips, thrusting them onto the desired object, and clutched her breasts tightly. Seth's cock, plunged into Mary's ass, began to gain strength, and soon Seth was having a hard time driving it inside his daughter's asshole. So he flipped her over onto her back and nestled between her thighs and drove his cock into her luscious cunt, which accepted it with a satisfied squelch. Seth fucked his daughter as unglamorously as he'd never treated any of his women. His petrified balls slammed against her ass, which Mary thrust up to meet his cock. Seth fucked her into convulsions, and when they subsided, he pulled out his device and showered his daughter with cum in an unprecedented hot stream.

- You're a great slut, Mary! - Seth praised, standing up and adjusting his clothes.

- But no one wants to go to the ball with me," she admitted with a sob.

- Don't worry, little girl, everything will work out.

Father was right. The boys must have sensed the change in Mary, because now they had no shortage of girls. Mary accepted the invitation of the captain of the school soccer team, but she only wanted this strong, handsome guy to impress her friends. She didn't want to have sex with him because now all her attention was focused on the man living under the same roof with her - her father. Mary and Seth fucked almost every day, at home, in the car, or in a rented motel room. They continue their sinful affair to this day and keep it carefully hidden from their wife and mother.
