So why was she angry?

Linda knew why.

She wasn't getting any herself.

And she wanted it, badly. All her life she had been deeply erotic, but had had to keep it bottled up inside her. Her ex-husband had had little interest in her, or any other woman that she knew of. He was satisfied to wham-bam, then turn over and start sleeping. She had never, not once, had an orgasm except that provided by her own fingers.

She had married as a virgin, even though she had grown up watching her brother jack off and had exposed herself to him many times for his pleasure. They had watched each other develop, pleased hair grew on his cock and balls and her tits had developed. Brett had touched her, but that came in high school. He had touched her tits, played with her nipples, and a number of times, felt her up. She had held his cock and cupped his balls as he jerked off, but they had never fucked. They just felt each other, and Brett would jack off, come, and that was it until the next time. It happened with them four and five times a week, and they had never been caught.

And now Brett was tip to his old tricks with his daughter and her son. What was she going to do about it?

Linda wasn't going to do anything about it. If Frank was enjoying himself – and obviously he was – she wasn't going to stop him. She wasn't even going to let him know she had seen them. She wasn't even going to let him know she knew anything at all about what was going on.

But she wasn't going to keep herself lonely, doing without a hard cock any longer. As she sat there, mad, she considered going back to her brother's house and telling him – no, demanding – that he take care of her, that after all these years, it was time he fucked her with that big cock. But Linda wouldn't do that. She wouldn't do it because her son was still there, her niece was still there.
