"Stop! Ohhh God, stop it now!" Rebecca made an effort to kick at him but Nate used the moment to force her knees wider and then her cries turned to deep moans as she felt his open mouth fit tightly around her young and feverish mound.

At first she froze, her muscles trembling as she held herself rigid against the slow, hot licking. The strokes of his tongue went deep into her crevice as he smeared her clitoris with spit then rubbed it the other way.

"Yeahhhhhh!" she gasped, her fingers fanning out against his shoulders. She was still pushing at him but not with much force. She felt her shoes being slipped off. Then Nate draped her long legs over his shoulders, never pausing for a moment with his mouth. He worked it back and forth against her swelling pubes as her sex honey dripped down like hot rain.

"Whhuuhhhh, ohhhhh God…"

Rebecca knew pleasure. But this thing that Nate was doing to her went beyond mere pleasure. It was like she was floating free of all worry or care. All that seemed to matter was the gentle rub of his lips and tongue against her squishy vulva. And at last she could keep still no longer.

"You!" she groaned, digging her fingers into his hair. "Ohhhh you awful, awful man!" Then her ass plunged as she rubbed her hot cunt up and down against his mouth. Doing this made her feel wrong but it made her body feel so good. She thrust her hips again but immediately felt the guilt and saw her aunt's face as if it peered down on her terrible sin.

"You must dig it," Nate breathed, looking up over her heaving belly, "you're squirming like a snake."

"I… I can't help it. It feels so strange!"
