Stacey wants a cock too.

To your surprise, Stacey looks sheepish all of a sudden. Once you both knew the marker worked, she was the more excited one, eager to test it out. Hell, look at your new abs as an example of the fun she wanted to have. But now that you were asking her what she wanted, she was frozen.

“Do you...” she starts to say, looking away from you. “Do you promise to not be mad?”

The question makes you laugh. “Yeah, I’m sure, I promise, I absolutely won’t be mad.”

She doesn’t look like she really believes that, but clearly decides to share what’s on her mind anyway. She mumbles her answer, so quietly you can’t hear it.

Putting a hand to your ear for effect, you ask, “What was that, lambchop?”

Blushing bright red, she thumps you lightly on one shoulder before saying it a little louder. “I want a cock...”

That is certainly not what you were expecting her to say, and you kind of get why she’s embarrassed. You try picturing Stacey with a cock, and the idea is equal parts confusing and arousing. “Just a cock?” you ask her, trying to sound like you don’t find anything odd with the idea.

She looks at you, astonished, and nods her head. “Uh...yeah. I don’t want to try fully becoming a guy, at least not yet, but I’ve always been curious about what it would be like to have a dick.”

You suppose you can understand that curiosity. You’ve looked at her vagina more than once and pondered what living with one of those was like. Giving her an encouraging smile, you hold up the marker. “Well, let me see that pussy, and I’ll get to work.”

She still looks shocked at how you’re taking this, but she’s suddenly all smiles as she takes off all the clothes on her lower half. Now the question is: should you give her a cock in addition to what she has, or replace one set with another?
