His mother, Angie

Hurrying so he wouldn't be caught jacking off, William had just enough time to pull his top sheet back over himself with his free hand. His other hand was still wrapped around his hard cock, the rigid shaft so close to erupting that it was twitching in his grip. As he looked to the opening door, his expression of fear turned turned to surprise as he saw his scantily clad mother in the doorway with a laundry basket balanced against her tilted hip.

"Good morning, Will! Don't mind me. I'm just making sure I have all the dirty laundry before I start on the next load," the thirty-seven year old blonde knockout greeted her son with a bright smile as she quickly moved into the room and set down the laundry basket. The sight of her heavy D-cup breasts wobbling as she walked made his cock twitch more and he squeezed it tighter to keep from cumming in front of his mother. She was wearing her apron, like she did most mornings, but as she crouched down to pick up a dirty sock, it became quite obvious that she was wearing nothing beneath the apron except for a matching set of lacy bra and panties, the thin material of her panties stretched tight across her plump backside.

"M-Mom!" The sight of her barely-covered peach-of-an-ass made his aching cock jump in his grip and his leaking precum began to soak into his tented bed-sheet. "Why are you naked?"

"Tsk.." She looked back at her son with an amused grin as she shook her head. "I'm not naked, Mister. I just waited too long to do laundry and this was all I had to wear today!" She did a quick scan of the bedroom floor and spotted something under Will's desk. Getting on her hands and knees, she reached under the desk for the item, making her huge slappable ass jut up even more.

Will let a soft groan escape his lips as he watched her panty-covered rump wiggling, desperately fighting off the urge to jerk himself off to completion as he watched her collect his dirty clothes.

Placing a pair of boxers in her basket, she turned to her son. "Did you say something?" As she was sitting on her heels, Will had a delicious view down the front of her apron at her pale cleavage.

"No," he replied with a nervous swallow. He had always known that his mother had a gorgeous figure, but now, as she crawled around on his bedroom floor in her bra and panties, thoughts that he'd never had before about her were now running through his head. "Just a yawn!"

She gave him a skeptical look, but didn't push him for a different answer. Angie climbed to her feet, giving her son another inadvertent show of her wobbling cleavage, saying, "Well, you'd better get up soon. Breakfast will be done soon and..." Her gaze was drawn to the sizable tent in his bedsheet and she frowned as she glanced to Will's face. "Is that a stain in your sheet? I just changed them last week!"

In confusion, he looked down to his sheets and saw the expanding spot made from his leaking precum. How could his mother be worried about a stain when it was so obvious what he was hiding underneath the sheet? "Mom! I--"

Before he could finish, Angie grabbed the edge of his sheet and gave it a yank. "I may as well wash them, since I 'm doing laundry anyways! Honestly, I don't know how you get your sheets so dirty so fast!" The sheet slipped from Will's grasp as she pulled it away and he was left bare on his bed, his throbbing cock rock-hard in his grip as it pointed to the ceiling. His mother had tucked the dirty sheet into her basket before she looked back to Will as he held his raging hard-on. Her eyes went wide as she saw the veiny shaft and she stared speechless for a moment before she glanced to Will's face.
