Tracy wanted to ask her mother many things, but she knew this wasn't the time. She looked at her mother with warm eyes, seeing her as a sexual person, a woman with desires just like her own. Dropping her gaze, she stared at the thrust of her mother's tits, seeing the nipples pressing upon the white blouse she wore. Then her gaze went lower, and she looked at her mother's knees.

Susan's skirt was a few inches past her knees, and seeing the way her daughter looked at her, she pulled her shoulders back and allowed her knees to open a bit. Tracy's eyes became hot and a shiver ran through her. She could see between her mother's thighs, almost to her panties.

There was a tension growing between them. Susan felt her cunt throbbing and had a wild desire to throw her legs wide and let her daughter gaze up her dress. She found herself wanting to look up her daughter's dress, to see her cunt, wondering if Tracy would let her. She wondered what it would feel like to touch her daughter, to feel the bubbly heat of Tracy's pussy and stroke her spongy, pointed tits and swelling ass. It excited her the way Tracy gazed under her skirt, a faint flush of desire on her beautiful fate.

Suddenly Tracy stood up. "I think I'll try it," she said, her voice throaty.

"Try what, honey?" Susan asked, her own voice filled with emotion.

"Bill," Tracy said bluntly, looking at her mother with bold, unashamed eyes.

Susan gasped as she looked at her daughter. "With your brother?"

"He's the only teen here," Tracy said. "If you can suck off the neighbor – and he's no older than Bill – why can't I fuck my brother?"

"Fuck your…" Susan said, the words coming out in a whisper, her eyes gleaming. "Fuck your brother?"

"That's what I said," Tracy replied, wondering if her mother was going to try and stop her. "Fuck Bill."

Susan licked her lips. "You can try," she said in a hoarse voice. "I'm not sure he will, but you can try."
