“Expires today. But that’s not the point. Who knows if it works against your gene structure?”
“Good question. Let me look...”
Katie looked between Elsa’s legs, saw that the fluid was, in fact, clear, and told this fact to Elsa, who was satisfied at that point.
“Tell me,” she said as started to clean herself up, “just HOW DO you turn it on and off?”
“It’s all voluntary. I pump one muscle long enough, supposedly, and sperm production starts, at which point I’m dangerous for a couple days. I squeeze something inside--” she pointed just above her belly button-- “ ... and hold it for a minute or two, and I’ll ovulate.
“What happens after you ovulate?”
“Well, after a couple of days I can be fertilized.”
“If that doesn’t happen?”
“Then it’s just like you. I menstruate. But just once unless I decide to ovulate again.”
“Can you feel it--- when you ovulate?”
“Supposedly ... I put nerve endings so I’d feel it when the egg is released. But I haven’t tried it.”
Elsa was sitting on the couch, and Katie went over and sat in her lap.
“You’re good, kid. Real good.,” Elsa said, smiling.
“Stop calling me a kid!”
“Alright ... After all, you didn’t make love like a kid ... Even if you do look like one.”
“I do not!”
“You do now!”
“Look, Elsa...” Katie took a deep breath, held it, and pushed.
“Yes, squirt?”
Katie bared her teeth, then swiveled around suddenly. There were breasts there now. They were larger than Elsa’s already, and still growing.
“I’m not a kid!” squealed Katie.
“Alright! Alright! I won’t tease you anymore. Stop before you embarrass me, or blow up or something.”
Katie smiled a tiny smile.
There was a knock at the door. Several knocks, followed by some voices. “Is Katie Mason here? It’s the Video News...” “ ... Herald Time Newsmonth...” all garbled together.
Elsa jumped up, and Katie fell backwards to the floor. Elsa grabbed her clothes and started dressing. Katie ran to the window, and upon opening the curtain, saw several news-crew trucks parked in the lot across the street, along with a small crowd. Someone pointed at the window, and Katie threw the curtains shut and stumbled to her room to get her clothes. “Just a minute!” Elsa yelled towards the door.
Katie, whose body was still wet with perspiration from her previous activity, grabbed a towel to dry some of it off, and dressed quickly. There was a wet spot on the floor that she’d have trouble explaining. No, they wouldn’t ask that. She turned the air exchanger up so that the sexual scents they had left would disappear.
Elsa was dressed and at the door. Katie hadn’t even put her panties on yet, so (with the central area free of underwear now), went into her room and closed the door. She locked it, which would be the first time ever that she ever had locked that door.
