"I'm going to cum, sweetheart! Stop! St-st-stop before I cuuummmmm!"

The moistly sucking sound ceased, and there was a smack of lips and another short groan before momentary silence.

"Now what about me! I'm totally neglected," came the pouting remark from Natalie's lips. Then she purred. "My little pussy needs petting, too. Do you want to suck my cunt? It might swallow you whole at this point," she giggled.

"Yes! Oh, yes!"

"Well, here it is, poor thing. Isn't it beautiful? It feels really good from when you touched it, but I want you to lick it."

"I'll put my tongue down like this. How is this? I'll suck your clitoris first."

"Yes, lick it. Suck my poor little clit. Oh, oh! You can fuck me with your tongue! Oh, Kev, your tongue feels gorgeous," his young wife crooned, and then her words ran off into further babbling obscenities.

Liz's heart pounded like a jack-hammer until she was certain they could hear it across the living room. She pressed one hand tightly to her tit as though to dull the sound. But it didn't stop. Instead, it lurched on, accompanying the soft rhythmic sucking of the girl's lips on her son's cock. Oh Lord, it was awful! She was hypnotized by the lewd wet sound of lips on flesh, and she gradually found herself losing control of her consciousness. It was almost as though her whole being was palpitating in unison with the couple, and she was moving off away from her own body and watching horrified as she lurched into the first warning tremblings of arousal that began to seethe around in her groin.

"Oh, darling, my sweet darling, oh, God, lick faster! Stick your tongue up my pussy. G-God, it feels so goooooood!"
