"Jesus, you're a filthy bitch!" Rusty groaned hoarsely. "Keep on doin' that, will ya?"

"Bet your ass I'm a filthy bitch," Amanda said between tongue-stabs at his brown, puckered skitter. Her hand was sliding from his balls onto the shaft of his cock, working it up and down, then coming back to cup and squeeze the balls again.

There was no way this cock was gonna get soft! She sighed deliciously, feeling the pulsation of power rippling through the stiffened prick. It had been quite a while since she'd had her hands around a cock as stiff and ripe and ready as this one, and she planned to fuck it dry! "You should lend this thing to my husband," Amanda whispered. "But I'm not sure he'd even know what it was."

"Why the fuck did you marry him, then?" Rusty asked.

"The money, of course," Amanda said, and she slipped the end of her tongue straight up Rusty's asshole while her fist worked his prick mercilessly. "He may be a dud in the sack, but he's okay when it comes to cash."

She moved her mouth onto Rusty's balls, sucking them from the rear. As she nibbled the bag of stones, she was tickling his shitter with the tip of her middle finger. His asshole was tight, but Amanda had determination and she had lust. She gave her wrist a flip and the sharp nailed finger slid straight into Rusty's ass.

"Holy Jesus!" he gasped. "Keep on doing that, baby! I think I fucking like it!"

Amanda knew she liked it. Her finger moved into his asshole, and it reminded her of those Chinese handcuffs-finger-locks, actually they used to have when she was a kid. Stick your finger in and then try to get it out again. She could move her finger in Rusty's asshole, but she couldn't quite get it all the way out.
