"Jessica" And Katie

You heard a click, followed by the sound of a blaster, one that sounded straight out of a cheesy sci-fi parody. Instantly, you heard the sound of leaking air as Katie turned to nothing more than a pile of skin, her clothes loosely containing her. Shivering, "Jessica" turned to you with a grin. "There's a bit of a draft!"

"It really works..." You muttered to yourself as you got closer. "And you're not wearing pants."

"Jessica" looked down at herself. "That would explain why she shouted." Looking back up at you, she smiled again. "You gonna put her on? You can get undressed before, if you want. It feels pretty good on your skin."

You gulped. "No, I'll be good. How do I work this exactly?" You asked, picking up what remained of Katie.

"Imagine an opening on her back. A zipper, a hole, whatever works. And then trace the outline with your finger. So a zipper is a line down the middle, for example." Your girlfriend answered. "Or... If you're in a perverted mood you can use one of the holes already there."

You decided to try that on someone else. As interested as you were, going into Katie... That way felt wrong. Especially with her mother/sister watching. Pressing your finger against the top of where Katie's spine should've been, you dragged it down imagining a zipper.

Like magic, Katie's back split in two, with her top falling to the floor. Now was the moment of truth. With a deep inhale through your nose, you stuck your hand in. Almost magnetically, your hand was drawn further and further in, until you felt a light tingle in your fingertip.

Wiggling your fingers, your eyes widened as Katie's hand inflated suddenly, mimicking what you were doing. You couldn't stop. Your other arm. Your legs. Your torso. Finally, only your head remained. Standing up, being Katie from the neck down, a few inches shorter than usual, you felt excited. Your new female parts quivered. That was... Interesting instead of a boner.

Taking a deep breath, you slid Katie's head on. It took a bit, but your features lined up with hers, right as the feelings started. Your brain felt like it was on fire, every inch of your body spamming it with signals of pleasure. You could feel your eyes rolling back into your head, your legs shaking as your hands and feet clenched.

A few minutes later, you came back to your senses, your female parts feeling especially hot and wet. "So it's the same for you. Huh." You heard "Jessica" say, who was now dressed and sitting on the couch.

"What are- My voice! It's Katie's!" You gasped, holding your throat.

"Yeah? I sound like Jessica, right?" Your girlfriend said with some sass.

"Good point. What, uh, exactly were you talking about? When I first came to?"

"Huh? Oh, yeah. It's just a theory, but whenever I put someone of the other gender on, I go haywire. Maybe it's my nerves getting used to the changes?"

"Thanks for the heads-up." You say with quite a lot of sarcasm.

"I forgot, alright? I haven't taken a man over in... Six months? You mom gives great road head, by the way."

"What."

"Okay, okay. Let me explain. You were taking that trip to uh... The Grand Canyon? I forget. Long story short, I needed a vacation. Paul was the only one who wasn't out and about the night before." "Jessica" explained.

"Dad was weird on that trip..." You mutter.

"Yeah, and Marie was HORNY. I don't think I got any rest during that trip, honestly. Good thing her tubes are tied, because I definitely would've-"

"Please stop. I don't need to hear about my mom and my dad, kinda, doing that stuff. I'm already scarred enough." You proclaim, rubbing your forehead. Well, Katie's forehead.

"Fine. Why don't you join me on the couch?" "Jessica" asked, patting the cushion next to her. "Don't bother getting dressed."

That made your body react, in a very unfamiliar way. Plopping down next to your body's sister... Who was actually her mother, you felt an arm wrap around you, pulling you closer. "So... 'Sis'. What are we gonna do?"

You suddenly felt that arm slide lower, before squeezing your butt. "You've got a lot to learn about the pleasures of a woman... Katie."

You had a feeling that this was going to get better and better...
