"Ooohhhh, nice!" Karen gurgled as she lowered her ass. "Ohhh, baby, that's one hard cock you have! Oh, I'm going to fuck the piss out of you, Tom! I'm going to fuck that hard cock of yours with my hot, wet cunt until you can't walk! Ohhhh, what a cock!"

Susan listened, watching, her pussy bubbling hotter with each passing second. She saw the way Karen's round, creamy ass spread, caught a glimpse of Karen's tight asshole, then Karen spread her long legs out on each side of her son's, her tits dropping to his chest. Oddly enough, Susan saw that Tom's face was just above his mother's tits. She hadn't realized he was that much shorter than his mother.

She watched as Karen's ass began to move, writhing from side to side, then pumping up and down. Susan could see the way Tom's cock penetrated his mother's hairy, slippery snatch, watch the pink lips cling to the sides of his prick. She could see Tom's balls draw up in reflex as he slid his hands over his mother's bouncing hips and asscheeks, groaning with pleasure.

"Oooo, Mom, Mom!" Tom moaned. "Oh, it's so hot! You feel so hot and wet!"

"You're damn right I'm hot and wet, Tom!" Karen replied, her hips bouncing furiously now, her cunt sliding up and down her son's pricks. "I'm hot for your cock, baby! My pussy is hot for that hard prick! I'm going to give you the best fuck you'll ever get!"

Susan gazed hotly at the way Karen's naked ass pumped up and down, the cheeks flexing. She watched the dark hairs cling to Tom's prick. It was the most exciting thing she had ever seen, and she stood there, firmly rooted to the floor, unable to turn her head away. She was breathing hard and fast, and she felt as if she would come just by watching. Her pussy was quivering insanely, and the insides of her thighs were moist. Her hips swayed gently, and she was gripping one of her tits as she watched. It was fascinating to her, intensely exciting.
