She's changed mentally

"Yeah, I think so." I help her into a chair.

"Are you sure? You inhaled some of that smoke. How do you feel?"

"A little annoyed. A little horny. And a funny feeling I can't describe."

Did she say horny? I must have misheard that. "I'm so sorry about this. I keep messing up. Why do you even keep me as an assistant?"

"Because I like how you look at me when you think I'm not looking."

I blinked. I know I heard that right. "...why did you tell me that?"

"Because you asked. I felt compelled to answer."

"Do you think this is some effect of those chemicals?"

"I can't say so for sure but it is a possibility."

Maybe I made a truth serum. Or is it something more? Only one way to find out.

"Jessica, stand up and take off your lab coat."

"Okay." She stands up and takes off her coat. Underneath, she has on jeans and a pink t-shirt.

"Hmm. Take off your shirt."

"Okay." Without hesitation, she pulls off her shirt revealing a pair of large, beautiful breasts held up by a purple bra.

"Um, take off your pants."

"Okay." She unbuttons her jeans and pulls them off showing off a heart-shaped ass in purple panties that matched her bra.

I swallowed hard. "T-take off your underwear."

"Okay." She unfastens her bra and lets it drop to the floor. Then, she pulls down her panties and steps out of them. Now completely naked except her glasses, I could clearly see that she had pink nipples that were erect and that her pussy had a neatly trimmed triangle of hair. The curtains matched the drapes!
