Susan jerked her eyes away.

"Wanda…" she said, then stopped. She stood up, her legs rubbery and weak.

She whirled away from her sister and almost ran down the hall to her room. She heard Wanda's laughter, and wondered about her lack of shame.

"Fuck him once for me!" she heard Wanda call just before she closed her bedroom door.

Tommy wasn't there. The bedspread was mussed, and the pillows were on the floor. There was the scent of fucking in the room, and she stood in the middle of it, wringing her hands, wondering how all this had happened in such a short time. Sure, she had been thinking about fucking Tommy. But she had not thought it would ever happen. She certainly never expected her younger sister to be the cause of it. But Wanda wasn't really the cause, she was only the trigger. The incident on the subway car had helped it along, too, she knew.

Tommy came out of her adjoining bathroom, still naked. He grinned at his mother, then saw her confusion.

"What's the matter, Mom?" he asked, starting to edge back into the bathroom, covering his cock and balls with one hand.

Susan understood what Tommy was thinking, and smiled at him. "It's okay, Tommy," she said. "It's not what you think. I just had a talk with your aunt, that's all."

Tommy stood in the door of the bathroom, his eyes searching his mother's face. Susan smiled wider, and stepped toward him. She shoved his hand away from his cock and balls, closing her own fingers about his cock and squeezing him.

"Gimme!" she whispered. "Don't hide it, give it to me."

"You looked kind of mad, Mom," he said. "I wasn't sure you'd let me do it again."

"Do it again?" she asked, squeezing his cock and feeling it harden in her fist. "You mean fuck me? Why would I stop you from fucking me? Didn't I say you could fuck me anytime and anywhere and in any way?"
