Marla reveals what favor she called in

You knock on the door of room 513, Marlas and Hailey shared room. You hear some voices from the inside, then Marla opens the door.

She wears a black shirt, leaving her belly exposed, and really short sport pants. Her hair seems to be still a bit wet from showering.
Hailey sits on an armchair by the window. She wears an oversized white shirt, her hair up in a bun, a bit wet as well.
Her pants must be really short, since you dont see any from under her shirt, which, admittetly, goes down halfway to her knees though.

You come in and quickly get out of your shoes. The room is similar to yours and Emilys, theres a big tv across from the bed, next to it window and armchair, and next to the tv the door to the bathroom.

"Excuse our wardrobe we just got out of the shower" Marla exlains, leaving you wondering if the two girls showered together. Marla sits down on the bed and knocks on the pillow next to her. "Come, sit with me."
You quickly glance at Hailey to see if she minds, but she just smiles at you and nods.
"So", you say, and look at Marla, "You talked with Lydia about..."
"The favor she owes us for cumming slower than me, yes.", MArla says bluntly. Again, your eyes dart to Hailey, and Marla laughs.
"Relax, I told her the story while we showered. I like to tease her a bit, although it´s getting kinda frustrating for me as well, I want my teasing to eventually pay off, you know? Instead I just have to watch her suffer. Which I dont mind, dont get me wrong, but its only half the fun."
Hailey blushes. She does that a lot. "Trust me, I wish I could change it." Then she looks at you. "But the whole story does sound kinda hot. I wish I didnt go get water on the moutain. I would have liked to watch."
Her eyes widen as if she had said to mutch, but you think its cute. Then Marla begins to talk again.
"So..the favor. I have yet to try out if it works, but I convinced Lydia to give us...a glimpse into her life."

She grabs the TV remote, and turns on the TV. Then, she connects her TV with her phone. You see her switch to some app you dont know and enter a code, then a picture pops up on the TV screen.
"Oh my god, it actually works."
On the screen is another hotel room. The angle shows you the bed, from slightly above. The camera must be on the wardrobe.
In frame are also the TV, the bathroom door, the armchair and...John and Lydia.
"What the..." you slowly say.
Marla laughs. "Isnt that cool? Lydia put up a camera, to which I can lock into at all times. I´ll give you the code as well, just download the app and you can watch whats going on in their room...and I think we´re really lucky look at that."
Hailey, Marla and you watch, as the action on screens unfolds.
