"Do you always cum in your pants when you kiss a girl, Jim?" Ellen asked, massaging the very warm nape of his neck, tracing the trembling line of his jaw with her finger.

"I… No girl ever kissed me like that before."

"I'm sorry. I didn't mean to. I couldn't help it," Jim stammered, all dizzy and steamy and feverish and terribly uncomfortable, but unable to move away from her.

"You know, I really ought to tell your father about what kind of a boy he's raising," she said, and let her nephew's face go white before smiling and going on. "But I won't. A boy your age deserves to have some secrets. As long as those secrets are between him and his favorite aunt. Did you cum all the way, Jim? Did it all come out?"

Ellen slid her hand down his heaving chest, over his belly and on to his cock. It was sticking straight up in his pants, and the front of his pants was quite damp as Ellen rubbed his cock and thrilled at the size of it, reached down and fondled his balls, and rhythmically rubbed his cock some more.

He couldn't answer her question. He could only grin and look down at the hand smoothly stroking his cock, and at the big pair of tits nestled up against him.

"Skinny, you've got me all weak in the knees. Let's sit down. And let's get you out of thou messy shorts."

With her hand on his cock, Jim would have followed his Aunt Ellen anywhere. She led him to the couch, sat him down, and poke to him in a smoothly authoritative way as she opened bit belt and his fly.
