Crystal mostly wore custom-built bras due to the unusual combination of her massive breasts and her relatively thin frame. Those didn't have standard tags or labels that gave away her measurements, and they were expensive enough that she was very careful with them. They certainly never wound up in the baskets with the rest of their laundry. Johnny had to sneak into her bedroom one Saturday while she was out shopping, and it took him a while to finally find one of her bras that actually had a label with measurements on it.
Then he could only stare at it in disbelief. He didn't even know cup sizes went that far up the alphabet! He had expected to see F or G, and would have been surprised by J, but this...Jesus. As it was, he could scarcely believe how big the individual cups were as he held the uncomfortable-looking bra out in front of him. In that moment, he realized just how badly he had underestimated the size of his mother's incredible breasts.
Then he had to hurry to put it away and straighten the contents of that drawer when he heard his mother's car pulling up in front of the house. By the time she came inside, he had covered his tracks well enough that she would never suspect he'd been going through the drawer that held her bras.

As the weather warmed up the second semester of Johnny's senior year, it only got worse for his overactive sex drive. Women began wearing lighter clothing that was more revealing, and that included three of his teachers who were younger, more attractive, and better-endowed. Even his baggy jeans barely concealed the outline of his rock-hard dick after those classes.
Johnny became adept at quickly jacking off in one of the bathroom stalls at his school once or twice a day. It gave him blessed relief, but he couldn't believe he had started taking such a terrible chance. Only the janitors noticed anything amiss, because three different times his massive cum shot had splattered on the back of the toilet rather than into the bowl. They just imagined someone had thrown up, because they didn't realize a human being could shoot that much semen all at once.
It was even more difficult for him after he got home from school on those warm spring days. His mother usually got home from work and promptly removed her uncomfortable bra and conservative blouse. Sometimes she would reach back to unhook it as soon as she walked in the door. All through the winter she had worn thick sweaters with an undershirt, or a long-sleeved pullover or sweatshirt. Those loose oversized garments had done a marvelous job of concealing her massive breasts.
Crystal never considered that her own son would even take notice of her voluptuous body. She had always felt free to dress comfortably at home, so she usually headed into her bedroom right after work and slipped into a pair of soft, comfortable shorts and a lightweight t-shirt or tank top. The tank tops were the worst for Johnny. Most of those were white, and while they weren't supposed to be form-fitting, they were usually stretched thin over his mother's huge melons. There was no way he could miss the way her thick nipples were constantly on display.
Crystal's nipples were large and very sensitive. They would get stiff with very little provocation, standing out an inch and pushing the fabric of her tops outward in two tantalizing, mouth-watering protrusions. She was only self-conscious of her huge tits and nipples when she was out in public. It never occurred to her that those very assets she was careful to hide from the world were being put on generous display for her son. She was actually more embarrassed by the thick, meaty lips of her pussy. It always felt to her like it looked big and hungry when she would see it in the mirror.
It wasn't something she thought about when she slid those snug, comfortable shorts up her legs after a long day at work, but she was presenting her son with a big, pouting cameltoe every time she walked toward him. Johnny was still a virgin, but it was almost impossible to look at that thick pair of vaginal lips without imagining a fat, hard cock sliding between them.
She might have noticed her son checking her out if she had not been so distracted by her own intense libido. Crystal was not consciously aroused by her own son, and didn't even see him as a man in her mind. She had no idea of the incredible, huge cock he was packing, nor did she have any clue how much thick, creamy cum he was depositing in the toilet and shower of his bathroom and in his wastebasket every day. It was the pervasive smell of all that semen that was turning her on, although she didn't realize that's what it was.
Johnny was careful to empty his wastebasket twice a week, before it would overflow with all those cum-soaked tissues. Quite frequently he would simply pick up the little plastic can with one hand and point his cock into it with the other, unleashing his pent-up load directly into the tissues that were already sitting in it. He always put another plastic bag into the wastebasket after he'd emptied it, so that disposal was simple enough. At any given time, though, there were usually two of those bags sitting in the garbage bin in their garage.
When Crystal got home from work, that warm smell invaded her nostrils as soon as she stepped out of the car. Her nipples and pussy immediately responded, but it only made her feel uncomfortable in her work clothes and eager to get out of them. She attributed her increased horniness to the fact that she hadn't dated or been laid in years, but she had a nice big dildo that she used to take care of her cock-hungry pussy. Increasingly she found herself fantasizing about a cartoonishly well-hung younger man who would fuck her senseless, but she did not realize her increasingly distant son was the guy in her fantasies.
Likewise, Johnny would picture his busty teachers or some other woman he'd seen when he jacked off. He didn't want to think about his mother that way, but his mind was simply filling in another woman's face to make him more comfortable. It was his mother's enormous breasts and puffy pussy he usually pictured when he reached orgasm, usually while his mouth watered at the thought of those stiff nipples filling his mouth.
Without being aware of it, they were turning each other on more and more, so both of them spent more time masturbating as the school year wore on. By the end of March, it had pretty much become their daily routine each afternoon. Johnny would come home first, right after school. He would quickly ditch his books and backpack in his bedroom, then he'd snag a pair of his mother's panties from the laundry hamper. In his bathroom, he would strip and stand in the bathtub, holding those fragrant panties to his nose while stroking his rampant cock to a rapid release.
It was simpler to clean up afterward, and let him spend more time working toward a second, more intense orgasm before he started the shower. Afterward, he would simply hide his mother's panties inside his clothes and then put them all in the laundry hamper. He wasn't trying to fixate on the smell of his mother's pussy juices; he figured her scent was similar to what he would smell if he found himself between one of his sexy teachers' thighs.
Johnny always used the shower nozzle to wash all that sperm down the drain, but it left a lingering odor. Neither he nor his mother noticed it consciously because the smell of shampoo and body wash made it less obvious. Still, it was infiltrating Crystal's nostrils as soon as she made her way to her bedroom to change clothes. It was the reason her panties were always damp by the time she changed clothes, and the reason she put them into the laundry hamper instead of wearing them beneath her snug shorts.
She usually checked on her son as soon as she'd changed clothes, and then she would retreat to her bedroom to take care of her horny pussy. At the same time, Johnny was usually in his own room, stroking his suddenly renewed erection until he deposited another load or two into his wastebasket. After they had achieved that temporary relief, they would join each other for dinner.
Those dinners always began comfortably—since they'd just gotten off—but grew tense by the end. Johnny was always careful to keep his eyes on his mother's face so he wouldn't stare at her breasts, but those enormous orbs wobbled and shook every time Crystal brought her fork or spoon up to her mouth. Her nipples usually stiffened over the course of their meal, although she didn't realize Johnny was turning her on. She never checked out her son's body, and his stiffening cock wasn't even obvious in his baggy shorts, but her peripheral vision was feeding images of a really big dick to her subconscious mind.
They would both be trembling and completely turned on by the time they'd washed the dishes every evening. Then they would retreat to their bedrooms for another intense round of masturbation. Crystal would plunge her oversized dildo into her needy pussy and moan as she frantically fucked herself. Over the course of the month, though, she began to have the odd thought that she really ought to be using a bigger dildo. She had no idea why.
