The sobbing sounds she made were soft, almost inaudible. Her shame was intense, her hopeless position frightening her more than anything she had ever felt. Her tits were uplifted by her raised arms, and shame flooded her when she felt her nipples swell, tingling as they pressed into the cups of her bra. She could no longer ignore the sensitive pulsations of her cunt and clit. Something exciting seemed to happen as Billy rammed his finger in and out of her asshole, becoming more brutal. Trying to control her fast breathing, Lynn gasped softly. Her ass was writhing slowly. The pleasant feeling, starting in her asshole, was creating a warmth in her thighs, her cunt and her tits.

No, I don't want this, she screamed in her mind. I can't stand it! Ooooh, please, please. What's happening to me? Why does this feel good? Why does it feel like I'm going to come? This is insane… I can't come! Not this way, not with a finger up my ass! I can't! I just can't!

"Ohhhh, I don't want to…" Lynn groaned, then her cunt exploded.

The convulsions of her climax sent heat waves up and down her body. Her cunt lips moistened, her clit throbbing sweetly. Her asshole sucked on Billy's finger. She moaned loudly in agonized ecstasy. Her ass twisted, grinding and going through a series of bumps like some stripteaser on a well-lit stage.

"Hey, I think I made Lynn come!" Billy gurgled. "I think she's coming, Tony!"

"How can you tell?" Tony asked, driving his fist back and forth on his cock.

"Her asshole won't turn my fucking finger loose? I think Lynn is cuming. Feel her cuming."

Tony slipped his free hand up his step-mother's thigh. He cupped her hairy cunt, feeling it oozing with wetness. Experimentally, he worked his middle finger into her pussy.

"Oh, don't!" Lynn groaned. "Don't do that to it! Not there! It's wrong, Tony!"

Tony was awed by the heat surrounding his finger, the wetness and how easy he could shove his finger into her cunt. Lynn's cunt was convulsing about his finger as her orgasm drew on and on.
