"Not a problem." Ty concentrated. A bag of marbles and a bag of walnuts appeared. He gaped all four of his pussies, and stuck out all four tongues toward her.
"Eager, aren't we," Lisa said, and his four pussy tongues all made beckoning gestures. "You're going to have to be patient. I get some of these too."
Ty was momentarily confused, then realized that she meant for her breast pussies. This ought to be interesting.
Lisa took two marbles from the bag, and gave one to Ty's leftmost pussy tongue. The tongue retracted, and she saw his pussy muscles work it in. He still wasn't as dexterous with the tongues as she was, having had less experience. "It won't go," he said.
"You have to be firm but persistent," she said. "Wait, do you have the cervix zipper too? Is it open?"
"I feel like an idiot," he said. He started trying to control the tongue in his womb. It took him a minute to find it and start to control it. Then he had to find the zipper pulls. After another minute, he had located all four, and tried them out. "I can zip and unzip all of then now."
"Ooh, can I see? I wasn't able to see my own!"
"Sure," said Ty. He gaped all four pussies wide, and turned his body so she could see into them. He sequentially zipped each cervix zipper, then in the same sequence, unzipped them again. She could see the marble still in one pussy, and as the zippers moved, she could sometimes see his womb tongue.
"I can see why you were so fascinated to watch me," Lisa said. "That really is damned cool to watch." Ty started to close the outer zipper of the pussy with the marble, but Lisa objected, "No! I let you watch me make the marbles disappear. Now you have to keep those pussies gaped, and let me watch."
"Fine," said Ty, gaping the pussy again, and using the enhanced muscles to move the marble to the cervix. It looked too big to go through, but as Lisa had suggested, he was persistent, and suddenly felt a pop and moaned. "Wow, that feels weird," he said, "but good!" He moved a different pussy tongue in a beckoning motion, and she fed him another. He moaned again.
"My turn now," she said, unzipping and gaping her breast pussies.
