The next day, the two of them staggered out of bed, still fully clothed and with a hell of a hangover. Neither of them remembered much about last night except for a loud rant about Zoe having a penis to give Emily babies. It wasn't until they were having breakfast and Emily was getting changed that they saw the box sitting on the floor, discarded and next to the bed, with its lid still open.
"Wow", Emily said, "It totally wasn't a dream"
Zoe haphazardly pulled off her skirt and dropped her pantihose, "Nup", she said, confirming that her penis was real with a tug, "Definitely mine it seems"
Emily chuckled, "Cool, I was hoping it was real", she said, walking over to Zoe, she threw her arms around her shoulders, "I would have been real disappointed if it wasn't"
Zoe and Emily kissed each other gently, before breaking contact, the two of them looked around at the mess in Emily's bedroom, and unfortunately it seems that there was no clothes left that were clean. Even the clothes they were wearing yesterday were completely filthy now. With a sigh, the two of them gathered all the dirty clothes together and took them to Emily's laundry. When they got there, they stripped off their dirty clothes, and threw them into the washer, along with the rest of the clothes they'd gathered up. Setting up the washer on a full cycle, the two naked women headed back into Emily's living room to wait for their clothes. Zoe made sure to grab the mystery box on the way to the room.
The two of them sat down on the smallish leather lounge next to each other, Emily watched as Zoe removed her penis, with a slurp it freed itself from her slick vagina and turned back into the dull plastic that it was before she 'installed it' into herself. Zoe replaced it in the box and closed the lid.
"So", Emily said, eyeing the box, "What was it like?"
"Strange", Zoe replied, "but I got used to it"
"Maybe tonight, I can have a try"
"Why not now?"
"Cause we're both hung over, and you hate sex when you have a migraine", Emily said.
"Oh yea", came the reply, "I suppose so"
Emily and Zoe snuggled naked on the lounge, their soft breasts rubbing against each other, tickling both in a very sensitive and familiar way. It wasn't long before the two of them were feeling very aroused.
The rest of the morning was spent with the two girls making out the traditional way on the lounge while waiting for their clothes to be cleaned. They usually did this when neither of them had the energy nor desire to have full blown sex, and with the lack of visitors Emily received, they didn't have to worry about people visiting them while they were both completely naked.
A few hours passed, the clothes dryer had finished its run and the two girls finally got dressed, Zoe hastily grabbed all her gear and headed for the door, with Emily following behind her, still barefoot.
Struggling to get her boot on, Zoe said to Emily, "Ly, I've got an assignment to get done by the end of the day, I'll try to come around tonight when I'm finished, assuming my folks don't try to ground me again"
"Ha-ha", Emily laughed, "Don't worry, if they threaten to throw you out again, you always have a place here in my bed"
"I think that's what they're afraid of", Zoe called back, headed down the path to her car, and "Love you!" she yelled before climbing in the driver door.
Emily waved back at Zoe, blowing her a kiss as Zoe's car sped off into the distance.
The ability to spontaneously produce sex toys that became real was a boon to the girl's relationship, as the weeks passed, each of the two girls would have a go at "being the man" in the relationship, alternating who used the penis and who didn't. Their sex lives became much more active, even for them, as their use of the realistic toys became more creative. It wasn't some time later that they realized they'd been using the toys for over a year and had still got a multitude of ideas and variations they hadn't tried yet.
As graduation day fast approached for Zoe and Emily, their academic lives took a bit of a priority over their sex lives, but the two of them still stayed together, trying to see each other once or twice a week at the very least. They alternated who had a penis during these weeks, whoever had it last in their sex sessions would keep it for the time it took until their next meeting, it wasn't long until both of them felt weird not having one between their legs.
Zoe even went so far as to buy some more comfortable clothing for them when they wore their "little man"; luckily Emily was a close enough fit to Zoe that they could share.
The duo of girls also started making more regular appearances at Jon and Karyn's place too, and starting to double date as well. Emily has easily proven that she'd gotten over Jon in the first few weeks of double dating with relative ease.
Zoe also took to regularly examining the stone, and her grandfather's old research notes while she was at Jon and Karyn's place, she was convinced that there was more to the stone then met the eye. Eventually it got to the point where Zoe would turn up on their doorstep with a microscope in one hand and a bottle of wine in the other. Zoe was convinced she could learn the stone's secrets.
Time continued to race by, the two girls were getting close to graduating, Zoe's graduate thesis was almost finished, it seemed like all her experiments on the stone really were paying off, each time Zoe examined it she learnt something new and eventually revised her thesis again. The floors in Zoe's bedroom were stacked high with papers, all various revisions of her thesis was coming in already in the range of 200 pages or so.
"Leave it to the smartest person in the world to figure out how magic works", Jon had said as a joke.
The scary thing was though, Zoe was convinced she had figured out what the stone did to effect changes on people and things with its wishes, but she couldn't figure out how. But the theories alone on what it did were enough to revolutionize the quantum mechanics field for years to come. Even as a student, Zoe's theories were getting out into the world and she was making quite a reputation for herself.
