Johnny was crouched outside the bathroom door, his eye nearly touching the keyhole as he stroked himself furiously. Inside was his mother, Elise, in the shower. Through the glass of the shower door, he could see her clearly and he loved every second of it.
"Oh god, mom..." he thought to himself as his cock throbbed in his hand.
Water cascaded down his mother's slightly-chubby body, dripping off her protruding light-pink nipples. Elise lathered soap along her thick thighs, unaware that her own son was just outside watching her every move. The shampoo bottle slams against the floor of the shower and startles Elise, her tits bouncing slightly as she jumps.
"God those tits, I need them so bad." Johnny thought as he stroked himself faster imagining his mother's tits wrapped tightly around his cock. Elise bends over to grab the shampoo, giving him a clear view of her shapely ass and pushing him over the edge. "Oh fuck yes. mom!" Johnny quickly stuffs his cock back into his pajama pants as waves of incestious pleasure course through him, he struggles to keep quiet as he fills his pants with cum. After making sure he was undetected, he slinks back into his bedroom with a look of pure satisfaction on his face.

For as long as Johnny could remember, he had a thing for older women, but none as much as his mother, Elise. She had raised him alone after his father ran off with his younger secretary, and they had only gotten closer and closer over the years. Many movie nights snuggled up on the couch, her large breasts pressing against his arm; he always had to jerk off violently in his room after that. Elise knew none of this, of course, and Johnny feared often how she'd react if she knew that her own son wanted to fuck her brains out. That fear never stopped him from looking, however, as at any opportunity, Johnny's eyes would roam across her body, taking in her curves, memorizing them, fantasizing about them. Looking was all he could do. Look but never touch... well, never touch her at least.

Sunlight peeked through the window blinds as another morning dawned. Johnny stirred from his sleep as he heard a knock on his bedroom door.
