Julian had glimpsed his mothers breasts - of a sort. Reflected in the bathroom mirror at a distance, in the landing of their suburban home he had ejaculated as he peeked at them. He'd paid a heavy price for this indiscretion, having been caught red handed. Or should we say, white handed, as his sperm spattered into his palm, witnessed by his shocked and upset mother.
Naked, with his bottom a distinct shade of pink, he had been sent upstairs by his mother following his punishment. In his hand was a trophy of sorts - his mother's panties, now soaked with his sperm and her vaginal juices, something entirely unfamiliar to him. Though he'd been told to wash them out, he had no intention of doing so. He wanted to inspect those panties, to cherish them, and to hold them close. He correctly suspected she would not discuss the incident in the living room again, and that she would not ask for them back. As he retreated up the staircase, his penis softened to it's normal state after having betrayed him as he laid across his mothers pale slim thighs. As it did so, more sperm leaked out of the little opening - a little white drop which he realized in the nick of time was about to fall onto the wood flooring, its stain betraying him once more. He used those lacy white panties to catch the drop as he climbed the stairs. The drop soaked into the panties to join the rest of the fluid which had been mopped up from his mother's lower body.
By the time he reached his bedroom, he knew these panties would join him in his nightly masturbation activities - they and they alone would be charged with the task of cleaning the head of his penis and to wipe down the sperm which would stripe his stomach each night.
In the meantime he inspected them closely. Though he could smell his own cum and see how his sperm had soaked into the fabric, the cotton gusset of those panties held a different juice - faintly yellow, with an distinctive and entirely unfamiliar scent. He brought the gusset up to his nose as he sat there naked on his bed and felt his penis stir again. His hand drifted down between his legs and with one hand holding his mother's panties to his face and the other pulling his foreskin up and down he felt another jolt of cum erupt from his teenage penis. The cum ran down the shaft, matted into his pubic hair, and soaked his testicles. Those panties had their second cleanup task within minutes of first being pressed into duty.
Meanwhile, downstairs, Jessica was calming down. Her breathing returned to normal and she contemplated her situation. There she was, sitting in the living room, bereft of panties, her wet pussy soaking her inner thighs, with her own son responsible for her flustered and disheveled demeanor. She sighed, got up and scooped her son's clothing from the living room floor, taking them to the laundry. She was not used to walking around without panties, especially with her labia and clitoris inflamed and so wet. It was a strange sensation. But she decided to quickly put the whole incident out of her mind and try to return to normalcy. Good communication between mother and son was not the hallmark of their relationship. And true to form, the two did not discuss what had happened right there in the living room.
But of course, neither had forgotten. Jessica knew what her son was doing behind his bedroom door, now firmly latched at night. One night she had found herself quietly patrolling the landing, standing still at his door, listening to the unmistakable soft sounds of her son masturbating, the rhythmic sounds becoming more insistent and the tempo increasing before a quiet gasp - a creak of his bed, and then, silence. The panties pressed into duty once more.
By the same token, Julian knew his mother's routine. Julian was thinking about what was going on behind Jessica's bathroom door when she came home from work. He heard the shower come on. He listened for the sound of the the shower door closing, at which point he knew his mother was naked, letting the water run over the smooth skin of her slim body. His penis strained with a hard erection as the shower was turned off and he imagined his naked mother stepping out of the shower and reaching for a towel. Jessica was always pretty sure of Julian's whereabouts while she was in the shower - right outside the bathroom door.
One day, as she was in the shower, she thought about what she should do about this. The problem was her actions and her inner self seemed to be disconnected. She didn't know why she listened to her son masturbate. It was this disconnect that prompted her that day to call to him as she stepped out of the shower and wrapped her torso in a towel.
"Julian, come in here please" she called. Julian was indeed, right outside the door. He was shocked to hear her mother's voice and he withdrew his hand from the front of his jeans where he had been fondling his hard penis through the fabric. His penis returned to its normal state rather rapidly from the surprise. He decided to give it a moment before replying, to make it seem like he was coming out of his bedroom.
Jessica wasn't fooled.
