Yes

"Oh god yes," Max groaned as his mom brushed her hand over his waistband and settled on his large bulge.

"I thought as much," Sherrie smirked. "Let's see the damage."

She dropped to her knees and yanked Max's pants and briefs down. They fell in a heap around his ankles. His thick and semi-hard cock straightened out away from his tennis ball sized gonads. It twitched as it grew steadily more erect with each passing second.

"Gosh Max, you've been hiding a python down here! You boys really are all the same aren't you?" Sherrie teased.
"Alright, let's get this taken care of. In future, I want you to come to me whenever your penis gets like this okay?"

Without waiting for a reply, she spat on his cock and rubbed it around his shaft.

"Sure mom.. jeez I never knew you were so freaky," Max grunted, taken aback.

Once his cock was slick with spit, Sherrie began pumping with careful but vigorous strokes. Max's beefy 9-inch member rapidly achieved full erection and swelled against her firm grip.

"Is this good honey? You just let me know what you need okay?"

Sherrie looked up at her son's face. She'd always loved him of course, but lately her love had intensified in a new way. She needed to care for him, nurture him and most importantly, satisfy him. The idea of completely and utterly meeting all of his needs in all aspects of life made her feel profoundly maternal. It turned her on. A new kind of lust that was unfamiliar to her otherwise fairly plain sexual experience. She knew that such a relationship was taboo, but she didn't care at all. She had never felt this way about anyone before. With the miraculous powers of this mysterious ring, she was going to be the best mommy possible for her perfect handsome man. Whatever he needed, she would provide.
