Katie, who is surprised to see you back up

"David!"

she exclaims as she becomes visible. She has a towel wrapped around her head and nothing else on. She instinctively tries to cover her exposed parts but soon stops as it doesn't work.

"How...aw, jeez. I zipped you back up before I got in the shower, didn't I?"

You make a mental note of that. You grab the black pen and point it towards her.

"Explain, now,"

you demand.

"What the hell is this thing? Why did you use it on me for a whole week? And what the hell have you done during that time?"

"W-w-well, I haven't done anything to fuck up your life if that's what you're wondering,"

she begins.

"It's just that...well...I've always wanted to know what it's like to be a guy. I'm not exactly the most attractive girl in school or the most confident. I wanted to see what guys want from a more intimate experience than I could get myself. So, when I found those pens, I had to try it."

So far, you're still debating whether or not you will accept what Katie's giving you. There is one thing bugging you.

"That still doesn't explain why a whole week."

She blushes briefly but long enough for you to notice.

"Well, I kinda got distracted..."

"Distracted by what?"

you ask. You think you already know the answer to this question, but you're giving Katie a chance to come clean.

"I...wanted the full experience of being a guy...and my sister being your girlfriend..."

Your suspicions are confirmed. She had her way with her own sister and probably very recently, too.
