Raising an eyebrow at the woman you look down at your plain t-shirt and baggy pants. You're twenty two years old, have a light complexion, brown short hair, and blue eyes that go back to the woman as you say, "Isn't it obvious? I'm a guy."
"Just have to ask..." She says trailing off as she enters some information on her tablet.
Looking back at you, she continues, "Now that I've explained the basics do you have any questions?"
Many questions fill your mind as you try to figure out what to ask. Watching this woman transform in front of you into an anthropomorphic sex monster had raised your arousal...
"What's it like? Transforming I mean."
"For me it's exciting as I know the fun will start soon. For others, they get their enjoyment out of transforming, especially into an opposite sex."
"Opposite sex? Like I could become a female monster?"
"Of course!" She laughs. "Gotta have a good supply of both sexes for battle!"
With this new information, your mind goes crazy with ideas. As you think of growing breasts and a vagina your face turns red.
A smirk crosses the woman's face as she says, "Naughty boy!"
Shaking your head you look back to her and respond, "Change me."
Nodding, the woman does something under the desk and a monitor raises from the desk showing a list of possible monsters to merge with. As you step closer to it, the woman says, "Choose one and we'll get you into battle."
