As Lisa watched, the bag the marbles had been in expanded, and Ty's body started shrinking. As Ty shrunk, marbles started appearing in the bag, and he said, "In this form, I'll still be conscious, and will feel stimulation with my surfaces. Being held will feel nice, and the tighter I'm held, the more stimulation I'll get."
Lisa reached a hand into the bag, pulling out two marbles. "Ooh, that feels great," Ty said, continuing to slowly shrink. She extended tongues from her top two breast pussies, and the tongues picked up the marbles from her hand. His shrinking body moaned a bit, and then even more when the tongues pulled the marbles into her breast pussies. With two of her hands, she started massaging her top pair of breasts. Ty's shrinking form shuddered in ecstacy.
"Will I be able to tell when you come?" she asked.
"Yes, that will make my marbles vibrate," he explained, as he shrank more, now only about six inches tall. The bag continued to fill, as his human body shrank away to nothing.
She used her other fourteen pussy tongues to each scoop up a marble from the bag, and pulled them all into her pussies. She used her tongues and enhanced pussy muscles to move the marbles back and forth in her vaginas, and massaged her four pairs of breasts with her eight hands. Too bad I can't also do that with my crotch pussies, she thought. Ty was in ecstasy, though she only suspected it. Holding the sixteen marbles in place with her muscles, her tongues shot out and pulled another sixteen marbles from the bag into her pussies, and continued massaging them. She stuck the ends of her tongues out and started rubbing the ball studs around her lips and clitorises.
After a while, she pulled her tongues back in, and started straining to push the marbles through her cervices. She worked at it sl9wly, but gradually increasing the pressure, until suddenly they went through. She had a huge orgasm as the marbles entered her womb, and her womb tongues started caressing them. She felt the marbles vibrating, and was glad that Ty was having an orgasm as well.
Her womb tongues continued caressing the marbles already inside her, while all of her pussy tongues shot out and started pulling more marbles from the bag into her pussies, over and over. She was able to get four of the large marbles into each pussy, and she played with them with her tongues for a bit, before starting to press them against her cervices.
