Try an indirect approach

The two sit quietly at the dinner table eating slices of pizza. Laura alone has eaten nearly half of the extra large pizza she had brought home, while Erik was only finishing his second slice. Erik watches his mother with intent in his eyes, thinking about what he had seen in the bathroom and in Laura’s closet. The amount of dried cum on the one disk case made him feel like prey sitting close a lion...and he liked it. Knowing his mother had a thing for mom son relationships was driving him nuts. As they ate he would steal glances at her body, mostly her crotch trying to see if her monster cock would subtly reviele itself. His mother had changed into a white sundress prior to leaving the apartment. Her huge tits pressed together showing off her cleavage, and her hips were accentuated by the tight sides of her dress. Tigh and motherly but a size or two too small for her shape. Erik “accidently knocks over a mostly empty cup he had drank from close to his Laura’s legs.

“Oops sorry Mom, ill clean it up,” Erik appologized as he grabbed a paper towl roll and began whiping the floor. Under the wooden table he presumed is the best place to get close enough to see his mother’s member. Laura was oblivious to Erik’s actions and continued to eat. Erik’s face was now less than a foot from his mothers crotch. He could smell the same scent of Laura’s cum balloon from earlier. But he could not see any kind of outline to her massive cock under the dress.

“How the hell does she hide this thing,” Erik thought.

Just then Laura finished the rest of the pizza knowing Erik normally eats 3 slices she left one more for him. She stood up with Erik still at her feet, and stretched moaning a bit. Erik’s face was inches from her crotch while she was standing. Then he notices every time she stretches there is a slight rise and fall of something near his face. Laura stretches upward one last time making the bulge pop out further until it brushes again Erik’s lips. He felt it, the outline of the cock head and foreskin glancing across his mouth. Just as quickly as it started his lusty event was over as Laura turned with her plate in hand away from the table. Erik watched as her plump ass jiggled in her dress as she walked. Walking toward the sink Laura began washing her plate. Erik unceremoniously sat back down and finished his last pieces of pizza.

Erik wanted his mother’s cock but needed a plan to convice her or to see it without her knowing?
