Ben, 18, walked home from what felt like the longest day of school ever. When he walked through the front door that afternoon, his mother was once again plunging her fingers into her silly cunt in the middle of the living room. This was not an unusual sight to Ben, as he had gotten used to his mom shamelessly masturbating in his presence.
Within the past year, Ben had to endure the tough divorce his parents were going through. Once his father moved out of the house though, something appeared to change in his mom Kristin; she began to take on a more rebellious side. She started acting up at work, which got her fired. Then, she decided to use some of the divorce settlement money to get a boob job which enhanced her breasts from a modest B cup to a dumbfounding 34F. On top of all of this she started to not care about anything she said or did, especially around her son.
Ben was once again embarrassed when he walked into the house that afternoon. Not because his mom had no sense of modesty, but because he always had a raging hard-on at the sight of seeing her stuff her fingers into her wet slit. Ben didn't want his mother to know how sexually attracted he was to her. In an attempt to hide it, he'd only ever steal a few glances at her explicit activity before running upstairs. Once upstairs though, it never took much time for him to explode into one of his mother's oversized bras. Today was no different.
Even though Kristin had lost all her inhibition, she still had a mother's intuition. Her little boy couldn't be less discrete if he tried. She knew that her son was running upstairs to release his pent up fuck sauce, and that it was always his busty mommy who was making him lose control of his hormones. Thinking about this frequently led the oversexed mother to an earth shattering orgasm.
In the three months since her son turned 18, Kristin had systematically tried to make him become as sex-crazed as her. The busty mother always wore revealing clothing around the house, which made her 5'4, 110 lb frame look all the more for fucking. She would also shamelessly watch porn and masturbate in front of her son in an attempt to make his cock twitch. She was pleased of her progress, as Ben often couldn't last more than a couple of minutes in those sessions before leaving the room abruptly to blast his cum everywhere. She wanted her son to obsess about her sexually until he couldn't take it anymore.
An obstacle in the way was that her son was always quite shy and extremely naive. Ben had come to believe that his mother's blatant teasing was either an attempt to give him more confidence, or that it was her way of telling him that there was no need to be embarrassed about sex. It didn't seem to work however, as he was often intimidated of being in the presence of the hottest woman he'd have ever seen. Because of the taboo nature, Ben was far too petrified to act on his impulses and fuck the living shit out of his mother. His head was telling him that it wasn't normal for sons to insert their strapping cocks into their incredibly busty mommies, but his cock always throbbed unbearably at the thought.
Ben didn't know what to think of his affections toward his mother Kristin. It never used to be this way, but her change in attitude (and newly surgically enhanced tits) suddenly made her irresistible to him. Kristin also picked up the habit of talking in the third person by calling herself "Mommy." Ben couldn't explain why he found that last part so hot, but it led to an addiction in browsing incest porn on his computer.
*DINNER*
When Kristin called Ben down for dinner later that evening, she acted as if nothing had happened earlier that afternoon once again. At dinner, Kristin wore a top that made her big breasts unavoidable. She paired it with a tight short skirt that made her heart-shaped, boner-inducing ass far too easy to ogle. Her son sat at the table mesmerized by her figure.
