"Oh, Sylvia, don't be like that," Jill purred. "I'm his aunt. You don't think I'd try to fuck my own nephew."

"He's not so little anymore, and you know it!"

"Now, now, Sylvia. Don't worry about a thing."

Jill giggled, sliding her hands between Sylvia's thighs, meeting no resistance as she spread them wide apart.

"Want me to lick it again?" she asked, sliding her finger back into her big sister's hairy, throbbing pussy. "Wow, Sylvia. Now it feels wetter than ever. You do want me to lick it, don't you? You need another cum."

"Go ahead," Sylvia whispered shamefully. Smiling triumphantly, Jill again pushed her face between her sister's legs, greedily sucking the fresh flow of musky fuck-cream from the swollen lips of Sylvia's cunt. She loved the taste of a nice, juicy pussy, particularly her sister's, but she still loved sucking on a big, throbbing hard-on even more.

Like her nephew's. Jill smiled secretly to herself as she worked between Sylvia's trembling thighs, hungrily lapping the tasty cream out of her sister's cunt. No way she was going to keep her hands off Tony, no matter what she'd promised.

Besides, she thought, she'd be doing Sylvia a big favor by fucking the guy. Maybe Tony wouldn't get big hard-ons in front of his mother if he knew how much his sexy aunt loved sucking cock.

CHAPTER FOUR

"Move over, Tony," Jill said, late that evening, smiling at her nephew as she joined him in her living room. "What'cha watching?"

Tony turned his head from the TV set, glancing at his aunt and then nearly falling off the couch as he saw what she wore. Jill had behaved herself all that afternoon and all during dinner, trying to put her nephew at ease. But it was eight o'clock now, and she'd been trying to look at his bulging crotch far the past four hours, and her pussy was dripping wet. Jill wasn't going to satisfy herself with finger-fucking when she was in the same house with her nephew's big hard cock.
