"Am I helping?" she asked after a minute or so.

"God yes! That feels great."

And Roslyn could see how great it was feeling. Her naughty nephew had an erection. It wasn't really what she would call a working erection yet. But it sure wasn't soft either. Her jogging shorts were starting to bind her. Right between the lips of her cunt.

"There, I can feel that old muscle now!" she breathed, letting her fingers probe down the inside of his groin. She was reaching higher than she'd dared before. She was almost touching the black silk pouch. But she pretended to be completely occupied by her first purpose, that of relieving Kendall's muscle cramp.

"Uhhhh," he groaned, relaxing some.

"You're so muscular," she said softly. "That's why you get cramps." Her knuckles brushed the lump in his g-string. She could see the shape of his prick under the thin silk. She could see where his glans flared out from the shaft. She wished she could really see it. The more she rubbed, the firmer grew the packed cockmeat bound in its hot, sheer sack. It was all Roslyn could do to control herself.

"Doesn't that feel better?"

"I think you got it now, Aunt Roslyn."

"I'll keep rubbing to make sure. If you want me to."

"Well. Sure. It does feel good." He was breathing irregularly. Roslyn was bending close to his belly. She could smell the faint musk of his cock now. It had, a healthy, sexy aroma. She barely controlled a rush of hunger. What would her husband Evan do if he could see her now? But he couldn't could he?

"Spread your legs more," she told Kendall. He did and she began to massage the inner surfaces of both thighs now. Her thumbs sank into the damp hollows between his balls and groin. The boy's prick was really stretching the silk of his g-string.

"Kendall," she whispered, "did you realize you've got a terrific erection?"
