It's only fair, she thought with a giggle. He began his life nursing on my tits and now I'd like to nurse on his prick. It's only fair, isn't it?

She sucked gluttonously on Jim's prick while she pretended it was Billy's. With her eyes closed it was easy to fantasize. She wondered what Billy's jism tasted like. She knew he jerked off at least once a day. She sometimes listened outside his door when no one was around and heard him beating his meat.

Jim's cock was totally stiff now and it pulsed against the root of her mouth. She slid the ring of her lips up and down his pole, dragging them slowly over the pulsating veins on his shaft.

At intervals she sank her lips all the way down to his cock-root. She pursed her lips around his dick-base and let his cock-bush tickle her nose.

He groaned and opened his eyes. "What the fuck's going on?" he growled.

She didn't answer. She didn't want to release his prick for even a moment. Then he chuckled. "You've got it up again," he said. "Well, go on and finish me off. Suck it good."

The overheated wife needed no further encouragement. She sucked more forcefully on his fuck-flesh. She squeezed the base of his cock while she suctioned in his cockhead. She jerked him off with her fingers while she licked and sucked his taut-skinned cock-knob.

"I'm gonna blow my wad if you keep that up," he said.

His cockshaft twitched wildly in her mouth and she stopped sucking. She knew if she continued sucking, his balls would explode and she didn't want that quite yet.

Scrambling around on the bed, she climbed on top of him and forced his cock into her cunt. "Fuck me!" she cried.

"Oh, Jesus, I'm tired!"

"But you're hard!"
