Once they appeared in Lisa's bedroom, Ty saw that they only had three minutes before dinner time. He set the knob on the special alarm clock to give them more time. He said, "I don't know about you, but I need some time to relax before I'm ready to join my family for dinner."
Lisa said, "I'm fine with that. I want to know what the heck happened. But also, I didn't get to enjoy the transformation I was expecting, so I'm still quite horny, and want to make love. How about doing that first? Either with or without transformations is fine with me."
Ty said, "Sure, let's do that. But I'm a bit burned out on experimenting with new transformations, after just having to clean up an unexpected mess again. For the moment, let's either have no transformations, or stick with ones that we've done before, without problems."
Lisa shoved the pillows off her bed, and transformed herself back into her mattress topper form, the size of the bed, with silky white fur, with two pillows, and with two very large cocks in the center of her many body, standing upright.
"I see that you're still set on being some cocks," Ty said with a smile. "That's fine with me." He didn't actually expect her to hear him, though, as she had not manifested any ears, or even a face. He transformed his body to a copy of her normal human body, but added a duplicated her pussy. He climbed atop her, and started slowly riding her cocks, and gradually picking up the pace.
After they both came, he realized that her cocks were still fully erect, so he assumed that she wasn't fully satisfied yet. He rubbed two patches of her fur to the sides of her pairs of cocks. Perhaps at first she didn't recognize what he was suggesting, so he kept it up, and after a minute she grew two more cocks. He split both of his pussies in two, for a total of four, side-by-side, making his crotch extra wide, and fucked her again. This time he didn't start gently. Perhaps she didn't expect that, as she reached orgasm quickly. He hadn't yet.
Her cocks started to soften, but he wanted more. He couldn't remember whether he'd ever done anything to reduce her male refractory period, so he did so now, and all four of her cocks immediately stiffened again. He rode her cocks again, hard, and this time she must have been making an effort to hold off her orgasm, as she didn't start ejaculating until just after he came.
Between the work he'd put into getting her reassembled, and now some great sex, he was quite tired. He lifted himself off her cocks, and lay down beside them, his head on one of her pillows. Her cocks gradually softened, and then shrank away to nothing, leaving just her flat, furry surface. She could have transformed herself back any time she wanted to, but since she didn't, he know she wasn't in any hurry. He dozed off, glad that the special alarm clock made it possible for them to spend as much time as they wanted before dinner.
Ty woke up later, feeling rested. He wasn't sure how much time had passed, in terms of the special time in the room, as the clock still showed nearly three minutes to dinner time. He got up and went to the bathroom in her en-suite, then went through the portal door and sat at his desk to use his computer. He noticed that he still had a copy of her rescued but unassmbled fragments in a file, and it occurred to him that perhaps he should have saved a copy of her assembled file, after Jupiter Supercomputing Facility I reassembled her, but before he transformed her back to human. Then he realized that he should ask her permission before doing such a thing unnecessarily. Copying her fragments to and between the computers and SSD as needed to get her reassembled was fully justified, he thought, but he'd have to ask her whether he should keep the copies of her fragments, or delete them.
For want of anything else urgently needing his attention, he started doomscrolling. After a while, he heard a little bit of noise from Lisa's room, and looked through the portal door. Lisa had transformed herself back to her usual, beautiful human self.
"Do we have time for a shower?" she asked him.
"Yes, the alarm clock knob is still engaged. We can take as much time as we like." He walked with her into the bathroom, and they started showering.
