Emily shows Chris her dick

"You mean my...?" Emily glances down at her lap pointedly before looking back to Chris.

Chris rubs the back of his neck, his face blushing awkwardly. "Uh, yeah, if you don't mind."

Emily grins as she puts down her doughnut and licks her fingers. "Sure, you can see it." She says, privately enjoying his eagerness. "Follow me." She says as she gets up, leading him to the men's room. Standing between the stalls and the lone urinal, which looked like it hadn't been used in months, Emily takes a deep breath and turns to face Chris. "This is day four." She says before pulling down her pants and underwear to show him her dick.

"Holy shit, it's so big already." Chris stammers, shocked by the effectiveness of the serum.

"It gets bigger too." Emily says cheekily, silently wishing she could become erect at will for comic effect. "It seems pretty average size to me though." She adds with a shrug.

"Average size on day four. If this keeps up you'll be over 20cm long by Friday." Chris says in wonder, eyes still glued to her crotch.

Emily chuckles, not unhappy with the mental image of having a big fat cock. "A risk I'm willing to take in the pursuit of science." She says wryly.

"It's a little odd you still have a vagina." He muses.

"I could say the same about you." Emily teases him. "It's pretty normal for me actually."

Chris rolls his eyes. "I mean the serum seems to have only effected your clit."

"Yeah, I picked up on that. Which is why I'd like to get some imaging done today, to verify whether it's true internally." Emily explains. "It will all make sense once you read my notes."

Emily pulls up her pants and starts to move towards the exit, but Chris hesitates, another question on his mind. Emily waits at the door, looking back at him curiously. "Would it be too weird for me to ask to touch it?" He asks at last, blushing even more.
