"God… Goddamn!"

"Ohhh yess, just let me fuck you! You're so nice to fuck!" Roslyn covered Mark's mouth and it seemed she was sucking the breath from him as her ass went wild. She rose and fell, made sharp, jerky circles as she ground that flared glans into the deepest pockets of her pussy. Ronnie wondered how much the guy could take without coming. She knew just how little lovemaking a man could take. It seemed that all of them were on the verge of shooting their jizz… even before they got it in a girl.

And now her Aunt Roslyn had pinned Mark's wrists to the bed and was fucking him with her thighs pressed tightly together. Ronnie knew that doing this would make her pussy very tight around the young man's rigid prick. He would feel everything more intensely. The slick friction would be increased. It was inevitable. He would come. But it appeared that Roslyn knew what she was doing. By her heaving breasts and trembling asscheeks, Ronnie guessed that she was about to slip over the brim of paradise herself.

"Yeeeessssss!" Roslyn cried.

"Roslyn… I'm gonna do it. Is it okay if I…"

"Come, darling!" She bit at his shoulder. "Oh shoot your lovely cum inside me!"

The boy gave a strangled cry and the muscles in his belly flattened. Ronnie was having a hard time standing. She clung to the windowsill as she watched her aunt grind the spurts of seed up out of the handsome young man's body. She could almost count each time the hot stuff fountained inside Roslyn's body. Mark would shudder and choke on a scream. Then his fingers would clutch deeply into the flesh of Roslyn's ass, Ronnie could almost see his glans pushing into the mouth of Aunt Roslyn's womb as it boiled its creamy sap out.

"Ghhhaaaaa!" Mark cried, his body rigid. He was holding his ass up off the bed as Roslyn fucked him with frantic, careless movements now. She licked his chest like a bitch in heat. She rutted shamelessly, her swollen loins smearing slick juice against his hips and belly.
