Thinking of her son and brother watching her, Laura increased the plunging of her finger. Her hips lifted slightly, the heel of her hand pressing against her distended clit. Alone now, she made soft whimpering noises as her ecstasy bubbled hotter inside her cunt. She wanted to tear her panties off, rip them from her hips, and brutally fuck her cunt with all four of her fingers. But she was afraid her son and brother would come back, see her panties hanging in shreds, vigorously fucking herself like some demented, sex-crazed whore.

That would be nasty.

Her father said she was a nasty girl, her husband said she was sex crazy.

Laura thought it felt good to be nasty, crazy for sex.

She plunged her finger in and out of her juicy cunt, listening to the exciting wet sounds her finger made. She spread her legs wider, arching her cunt to her hand. She squeezed her clit hard, feeling a delicious sort of pain stab through it. She opened her mouth and made soft sounds of rapture, eyes squeezed tightly, her imagination out of control now.

She thrashed her hips about as her finger stabbed and stabbed, reaching for places she had never felt before. Her panties were stretching, ready to tear, but she didn't care. He cunt was pulling and squeezing at her buried finger, clasping it hotly.

Her finger became a cock, a hard cock.

Then it became her brother's cock.

And then her son's cock.

Laura jerked her hand off her tit and stuffed her knuckles into her mouth, stifling the sudden scream of ecstasy as her cunt gripped her finger with a powerful orgasm.

For a long time she shuddered, her body slowly relaxing. She felt the pulsations around her finger as her clit kept twitching. She removed her knuckles from her mouth, now that the threat of a scream was over. She moved it down and cupped her other hand inside her panties, holding her pussy until she recovered a bit of strength.
