It was like sucking on a warm, velvet-covered marble, with that big sexy tit behind it. Jim sucked and licked her nipples as she'd told him, softly and gently, while the heavings of his aunt's chest kept thrusting her tits against his face. He got his hands on some naked tit, too, though he couldn't get all he wanted of this and still guide his wet cock back in the tight, hot hole between her legs.

She wasn't helping him now. She was laying back against the arm rest, grinning and softly writhing her beautiful body, and running her hands through his hair while he sucked on her tits. Down below, Jim was shoving and probing with his cock, encountering tantalizingly sweet, soft cunt flesh, but unable to find her hole. He had an awful fear that he'd do the wrong thing, that he'd make a mistake and shove his cock up her asshole and thus ruin everything between them. But then it was suddenly in her, all the way. The full length of his naked cock was being sucked and tingled all over by the very live cunt of his aunt, and she was starting to go crazy again.

Jim didn't know what there was about it, but he loved to see her this way. He'd never even known women could cum before, but now that he'd seen it happen once, he wanted to see it again and again.

"Fuck me, baby! In and out and do it good and fast and hard," said Ellen, throwing her hips up against his loins time after time in rapid succession, digging her nails in his back and thrashing about so that he couldn't keep hold of her nipples with his mouth.

That didn't seem to matter so much to her now. All she cared about flaw was the cock plunging up in her cunt, and so Jim pushed himself back from her jouncing tits and reached up and got both his hands full of them.

"Oh-h-h, my God!" Ellen cried, and her cunt squeezed down on Jim's cock again, and her body arched upward and shuddered all over. An enormous feeling of power swept over Jim, and he kept right on pistoning his cock in her cunt and squeezing her tits very hard as she cried out, "Again! Again! Again!"
