"We have a while before we have to get ready for dinner," Lisa said. "This time, make _your_ body stretchy!"
"OK," Ty said, curious about what she wanted. He made his body stretchy.
She grabbed his big toe, and pulled it. His toe, foot, and leg all started stretching. She pulled his toe up over his head. "Yes, this will do," she said, and gradually pulled it back toward its normal position before gently releasing it.
"You want to play with my toes?" he asked. "Is that something you're into?" he joked.
"I love all of you," she said, "but no, the toe was just testing your stretchiness. Now, remember how big you made your cock inside my stretchy body, shrinking the rest of your body?"
"Yes."
"Do that again, but outside me."
"OK. I didn't need to become stretchy for that," he said, as his cock started growing, and his body shrinking.
"I know. The stretchy part is later. In fact thus time, make your cock even larger. About seven feet long, and three feet around. And make sure you can still hear me after your body is gone."
"OK," he said. His cock was becoming enormous, and his body tiny. As she watched, his cock reached its final size, longer than the bed, and his body disappeared.
"Are you listening?" Lisa asked the cock. It pulsed once. "Good." She pushed the bed out from the wall, so she could get to the cock head. It was bigger now than his normal human head had been. She rubbed her fingers across the flesh, and he shuddered. She stuck her finger, then her whole hand, into his urethra, and he came, a giant torrent of cum exploding out, pushing her hand out of him.
"Too soon," she chided him. "You need to control yourself more. Can you p,ease do that for me?" His 'body' pulsed once.
"You said something earlier about toes," she said. "Let's try this." She lifted one of her legs, and shoved her pretty little toes in his urethra. He shuddered, but did not come. "That's better," she said.
She withdrew her toes, and said, "This bed is too small. Can you make it about fourteen feet long? Expand the room if need be. And keep your base near the foot of the bed." He had been hanging off the end, but the bed and room started enlarging, and quickly reached the size she asked for. "Perfect," she said, and he pulsed once.
She climbed on the bed, nearer the head, and lay down, her feet near his head. She inserted her toes into his urethra again, and he shuddered. She continued pushing and got her entire foot into him, up to the ankle. She felt him tense up around her foot, and said, "Not yet!"
She inserted her other foot into him, and he shuddered again, but did not come, though she suspected that required a lot of will power. And she would require yet more of him. She scooted towards him a bit more, shoving her feet further inside him. She continued until she was in him up to her knees, and his shuddering was getting quite pronounced. "Keep it cool, big boy," she told him. "Can you do that for me?" One pulse, which she felt squeeze her lower legs. It felt nice.
She continued scooting down the bed, shoving her legs further into him. Due to his huge size, it wasn't too tight a fit. Yet. As her upper legs continued to go in, he got somewhat tight around her thighs. "This is why we needed you stretchy," she said. One pulse. She pressed on, and with some difficulty managed to get her hips through his opening, which definitely had to stretch some to accomodate them. He shuddered again. "You're doing great, keep up the good work!" she told him. One pulse.
She was in him up to her waist, and was really enjoying the sensation of his cock pressing tightly all around her. She squeezed one hand into his opening, between her thighs, and started rubbing her clit. She felt him tense up. "Not yet," she said again. One pulse.
She continued pushing her way in. Now his tip was touching her breasts. "This will stretch you a bit more," she said. One pulse. She gave a big push, and got her chest inside him. It was a tight squeeze. She continued pushing. "I forgot to ask. You need to remove my need to breathe." She felt a change, and one pulse from Ty.
She gave another big push, and her shoulders went in. Now his urethral opening was around her neck, and the one arm she still held up out of him, to push with. She shoved that arm inside him as well, and now only her head was outside him. He shuddered. "You doing OK?" she asked. One pulse. "Need a break?" Two pulses.
Now she had to push against his own flesh, to force herself further in. She did that several times, and the top of her head was just inside his opening. She pushed again and again, until her head was below... his cock head.
"Ready?" she asked him. One pulse, now all around her, It felt amazing. She resumed rubbing her clit with one hand, and used the other to rub her breasts. She used her legs to move her whole body up and down within him, massaging his cock from the inside. As her own pleasure grew, she could tell his was as well. She rubbed herself against him faster and harder.
At last he could hold off no longer. She felt intense contractions start around her, and knew his cum would try to force her out. She rubbed her clit harder, and used her other hand to try to brace herself in place.
Just as her orgasm started, his cum forced its way past her body, in giant, slippery, rhythmic spurts. With great effort, she kept her own body from being spurted out of him, and she continued masturbating. After a few spurts, they became less intense, and gradually tapered off. Her own orgasm did as well. She was exhausted, and content to lay within him.
After a while, she asked, "Ready for the next step?" One pulse. "Return your body to normal size, but shrink my body with it." One pulse.
She didn't feel his cock shrinking around her, because she was shrinking at the same rate. She did feel a shift in position, as his cock was once again a small part of his larger body.
"Lisa? You OK?" she heard him ask.
"Fine," she said. "Very tired. That was a lot of work. This time you're running the show. I want you to masturbate."
"If I squeeze my cock, won't that hurt you?"
"No, I made myself stretchy again."
"OK," he said.
She felt the pressure aground her increase as he gripped his cock. The pressure went up and down. She thrust her hips forward so his strokes directly pressed against her, and she started masturbating.
She could feel his pressure build up, and her own. They came simultaneously. This time she made no effort to brace herself, and was shot out of his cock on a rope of his cum. Her tiny form, landed across the room. "That would have hurt if I hadn't made myself stretchy," she thought.
After he finished ejaculating, Ty stood up. He searched the room u til he found her, and gingerly picker her up. "Are you OK, little girl?"
"Fine," she said, "just very tired. Please put me on your bed and let me sleep for a bit."
He lay down on the bed, and set her tiny form next to him. He shrank one of the pillows on his bed to doll size for her, and carefully placed it under her head. He was tired to, and drifted off to sleep.
