Fingers pulled at the hair of her cunt, sending a searing pain through her crotch. She twisted and wiggled, but the ropes held her secure in the obscene spread-eagled position.

Freddie and Tommy pulled back, looking at her tits. She watched them step back, then squat down. They looked up between her legs, staring at her cunt. Susan knew her cunt was open from the way her legs were stretched. Shame flooded her face as they looked at her pussy.

Freddie and Tommy saw the pink lips of their mother's cunt. They saw her slightly swollen clit. Freddie slipped his hand to his mother's cunt and cupped it, squeezing with a finger almost inside.

Susan's shook, her hips jerking back.

"Don't!" she snapped. "Don't do that!"

Freddie laughed. "Why the fuck not, Mom? What are you gonna do to me – spank me again?"

He thrust his finger into her cunt.

"Ohhh, damn you!" Susan shouted. "Damn you! Damn you!"

Freddie began to plunge his finger in and, out of her cunt, and, to Susan's horror, she was becoming wet. She tried to will her cunt to stop, but the more his finger thrust into her, the wetter she became. She was responding to them, not wanting to, but responding just the same.

There was a tingle in her cunt that she had not felt in over two years. Susan knew that if her son kept fingerfucking her, she would come.

"Let me do it," she heard Tommy say.

Freddie pulled his finger out, and Susan felt Tommy shove his into her. She could not resist looking down her naked body, watching them. They were so absorbed in staring at her cunt and watching their fingers fuck her, they didn't look up.

Susan could see their cocks, thick and long and very hard, pre-come seeping from their piss holes. A shiver rippled up and down her spine, and her cunt seemed to steam.
