Aunt Sue licked both sides of the deep ass-crack, and the entire length. She tortured every nerve there. Terry begged her not to stop, the girl's cries music to Sue's ears.

The woman licked harder. She began to slurp loudly and, lewdly. She soaked the ass-crack with her spit until more of the goo began to run down the backs of Terry's thighs.

And Terry was beside herself with joy. Her ass jiggled wildly. Her tits bounced and swayed to and fro. She began licking her lips and drooling deliriously, apparently overcome by her aunt's hot, slithering tongue.

Auntie began probing Terry's shit-bung, and Terry grew wilder and louder. Terry worked her shit-hole muscles in an apparent effort to relieve the mind-blowing sensations that were no doubt shooting through her shitter. Aunt Sue was careful not to get her tongue caught in this meaty trap.

With her niece's shit-hole pumping continuously, Aunt Sue moved her head this way and that, ramming her spitty tongue against Terry's shithole. In her eagerness to plug up Terry's shitter, Aunt Sue nearly blew the child's mind.

Terry trembled and groaned and squealed and howled as her aunt's hot tongue attacked her shitter repeatedly. Sue could easily imagine what her niece was feeling, for she herself had had a hot tongue up her ass many times before. She knew her hot tongue was like a rasp on Terry's tender ass meat, a rasp that was scraping the girl's ass raw. A sudden squeal told Aunt Sue that she was right.

Auntie also knew that bursts of heat were soaring up into the young blonde's shitter. She wondered how the girl could take it. She herself would have probably collapsed in a heap by now. She began to develop a healthy respect for her niece as she worked her tongue around and around Terry's puckered shit-bung.

"You're driving me crazy!" Terry shouted at last, while squeezing her own tits. "I can't take any more of this!"

"Shall I stick my tongue up your pussy?" Aunt Sue asked, lifting her head.
