She's very dutiful

My eyes were boring a hole in the airplane bathroom door. Come on, pet, you can do it... I thought to myself.

Stacy, meanwhile, was laughing. "You lost control, Mister. Did you notice anything about the pictures Laura sent her boyfriend? She didn't even show him everything. She's told us before that was one of the reasons they broke up. She's too shy!"

Of course, while Stacy was gloating, you were receiving a new message:

"Oh really?" I said, showing Laura's naked body to Stacy and her seatmate. Stacy looked astonished.

"Well fuck me," she said. I grinned.

"Here, watch this," I said. I texted Laura, Very good girl. Now, let me see your ass.

Not 15 seconds go by before I received this:

"Damn," Stacy said. "You've got her under a spell."

"So it would seem," I smiled.

How are you feeling? I texted.
_Horny, _she answered, obviously leaning in to her requirement to tell the truth.
Show me.

A few moments went by. Then...

Good girl. Fuck yourself. But do not cum.
Yes, sir...

I didn't share these particular messages with Stacy or her friends, who were chatting among themselves. I was happy to leave Laura alone for a minute, imagining her taking care of herself.

"So, have you thought about your own challenge?" I asked Stacy.

"Yeah," she said promptly. "I know what I want you to tell her to do."
