"Meh, I think maybe it'll be fun if I switch places with Melissa. What if I'm the hot girl, and she's the studly guy? I've always wondered what girls feel like." Mike began to input settings to change himself. He makes sure to make himself a really hot girl. "I don't think I'll put my clothes back on, just to enjoy the change."
Mike points the gun at himself and fires. As the blue glow hits him, his hair grows longer and his face grows more feminine. "Wow, this feels great!", he said, in his new higher voice. His tits began to emerge, 2 big ones on his chest. His waist got skinnier, his hips got wider, and his butt got bigger. His dick sunk into his body, replacing it with her new female pussy. "Whoa... That's an awesome feeling...", she said. Her body completed her change, and her old boxers changed to a pair of panties, as a bra appeared on her chest. "Wow... I'm so hot...", Michelle said, groping her own breasts. "Heheh. Now for Melissa..."
Melissa walks into the room after taking her shower, only wearing a towel. Michelle shoots the ray at her and her towel falls off. Melissa's hair began to shorten, changing to a shorter cut. Her face became a bit more rough, growing a bit of stubble. Her breasts sunk into her body creating a flat chest. Her arms, chest, and legs became muscular, like a football player's. Finally, her crotch began to change, as a 6-inch dick. Surprised, but not noticing anything, Marcus went over to the bed where Michelle lay. "Hey babe, I'm done with my shower.", said Marcus. "Oh god you're so hot. Uh... wanna... do it?", said Michelle, reluctant to have sex as the opposite gender. "Alright, babe. Let's do this!"
They got into bed, and Marcus started thrusting into Michelle. "Ohhh....", she moaned. After a while of this, Marcus backed off, and laid down, waiting for Michelle to do something. "Uh...", said Michelle, staring at his erect dick. "Aren't you gonna suck it? You always say that you love that." "Um... sure." Michelle decided that if her female side liked doing it, then she'd like it too. She put her mouth on his dick and started sucking, as it squirted cum into her mouth. It was delicious, and she couldn't get enough of it. Her mind began to fade, and she blacked out.
