Then, when Jess's fuck-juice was flowing freely, she buried her mouth into the girl's cunt and sucked it up.

Jess had never experienced anything like this, and she lay clutching her lovely tits and bashing her head from side to side.

"Aw gee, Cass, that's heaven! I want to cum. I never thought it could be so wonderful!" she cried.

"I'd love to watch a big cock going in and out this cunt," said Cass. "You'll let me watch you when you have a fuck, won't you?"

"Ooooh, yes, and I want to watch you and Jack fucking, too. And I want to watch you fucking with other guys."

Cass kept sucking her cunt greedily, then slipped her tongue deep in between the inner lips and flicked it from side to side. The smooth flesh of the entrance to Jess's fuck-tunnel was pulsating with excitement.

"That's heaven! Keep doing that!" Jess cried out and arched her back.

She thrust her groin at Cass's mouth and clamped her thighs against Cass's neck so tightly that Cass had to pull back and take several deep breaths.

"Don't strangle me, honey," she said.

"Oh, Cass, it's so beautiful I could go on forever!"

"I haven't even started the best part yet," she told Jess. "I'm going to make you cum, but don't fasten your legs around me too tightly or I won't be able to breathe."

Cass flattened her tongue and licked Jess's slit from her asshole to her cunt-mound in broad, tingling strokes, slurping up fuck-juice as she went along. Then she pointed her tongue and pushed it into Jess's slit.

"Oh, Cass, deeper, deeper, put it farther in!"

Cass stopped for a moment and giggled.

"I can't go any farther in, darling. My tongue's not as long as a cock, you know."

"It's lovely, Cass. I've never had this before."

Cass fluttered her tongue from side to side inside Jess's slit until she reached her clit.

She took a deep breath of surprise as her tongue slid along the sensitive, throbbing clit. It was standing up under its little hood like a miniature prick.
