Shelly had made up her mind.
She put down the clothes she was eyeing, and began to follow him. "Maybe he'll be headed to the arcade? I should be able to keep my distance at first."
She kept him in view, but stayed as far back as she could afford. After all, she didn't want to call attention to herself. She couldn't even believe she was doing this, it was all so wrong! He was so young!
For just a moment, a wave of regret and disgust washed over her, shocking her to her senses. What was she even doing? This wasn't at all who she knew herself to be. Her pace slowed for just a second, until her eyes drifted back to the unevenly-walking boy. He had tripped slightly, causing him to nearly fall. As he caught himself, he stood, momentarily, in a very awkward stance to regain his balance, which pressed every thick inch of his anatomical glory against the sheer fabric of his shorts. Even at this distance, Shelly could see not only that this boy had more inches than she'd ever even heard of, but that his obviously cum-laden nuts were so absurdly overly developed she estimated they wouldn't both fit in her hand.
She felt that familiar heat wash over her again, the dampness in her panties worsened, and she continued to follow him. She could not let that cock get away.
Just as she was running through a few openers in her head to say to him, her eyes widened and her jaw nearly hit the floor.
He'd found his mother, it would seem, just outside an outlet department store. He was clearly glad to see her, though he was also doing his best to conceal his body problems.
His mother was none other than Susan Bailey; her friend and coworker. She ran back through several conversations with her, how she had a son about that age, and how concerned she was with his struggling sense of self-confidence. It all added up.
"Of course he's self-conscious, he's got over a foot of dick in his pants!," she thought. Though this did present an opportunity. It would all depend on how she decided to proceed.
