They were taking turns fingerfucking her. The insides of her thighs were slippery with juice as they switched fingers. She could hear them breathing faster and she began to hope it would end soon. Maybe, she told herself, they would come fast, then untie her. Could they come? she wondered. They were very young, and she knew nothing about young boys, at what age they started to come.

Susan began to whimper softly. There was that familiar tingle in her cunt, and she could feel her clit swelling, distending into a throbbing hardness. She choked back a squeal, not wanting to come, not wanting them to know she was going to come. But she couldn't prevent it. Her hips were thrusting now, moving back and forth, grinding within the limits of the ropes.

She clamped her mouth tight, her bottom lip between her teeth.

She came.

"Hey, look at what her cunt is doing!" Tommy said with excitement.

"She's coming, Tommy!" Freddie exclaimed. "Hey, we're making Mom come!"

Freddie plunged his finger in and out of his mother's cunt fast, feeling it suck and squeeze it. Her clit was throbbing visibly, and Susan was crying with shame, yet with ecstasy, too. She had been betrayed by her cunt, and there was nothing she could do about it. Her face was flaming with shame, and her hips thrust back and forth, fucking on Freddie's finger.

"Look at her come!" Tommy shouted gripping a cheek of his mother's tightening ass. "She's really coming!"

"Her fucking cunt is about to squeeze my finger off," Freddie said. "Look how wet her fucking cunt is!"

The orgasm increased, and Susan cried out as she began to come a second time.

"I gotta gotta come, too!" Tommy shouted, gripping his cock in one tight fist and his mother's ass with the other.

Tommy shoved the head of his cock to her thigh, and Susan felt the hot, bubbling come juice spurt over her smooth flesh. It seemed to scald her leg, and her orgasm increased suddenly. She shot her hips forward, crying out again with unwanted ecstasy.
