Nothing

"What do you mean?" Asks Matt.

The camera of his phone is framing perfecly Miranda from the waist up now.
You have to say that her boobs looks quite bigger, from this point of view.

"I mean, i suppose you could start before i send that message... No one will ever find out, and it's not exactly like cheating either." She replies shrugging in her shoulders.

"Cool, sure, but ... shouldn't you be already undressing then?"

"Oh, that ..."

You see your crush fiddle with her hands nervously.

"Yeah,that ... it's not a minor detail, you know."

"It's just that i though we could ... overlook that part maybe?"

"Which part?"

"The one where i undress ..."

"How i'm supposed to see your ... you know ... muff, then? With my x-ray sight?"

"Err ... you are not?"

"Excuse me?"

"Oh come on, Matt, we're between us now ..."

"And what does that has to do with it?"

"I don't know ... we grew up together, do you really want to see me ... Wouldn't it be awkard?"

"I don't know ..."

"Would it even ... turn you on?"

"What do you mean? Why shouldn't it?"

"Wouldn't it be like jacking off to your sister? To your ... i don't know ... cousin? We've known each other for so long, that you're almost a brother to me ..."

"Hold on, my cousin is a real babe. I almost lost a diopter on her instagram profile's pictures. Apparenly that girl doesn't do much studying there at UCLA ..."

"You mean like ... you used her picture to ... masturbate?"

"It's not that bad. A few years ago was common for cousins to marry between each other, besides me and her, have never been really much close..."

"That's still gross, Matt, eww!"

"I'm not sure that i'm getting your point, honestly ..."

"Well, i just tought that you would have simply preferred to ... do without me stripping, given our relationship. " She replies hesitantly.

"It would stay just between me and you, if you agree, i promise." She hurries to add.

Hearing Miranda now sheds some light on her behaviour.
That's why she seemed almost grateful of Matt's proposal.
She thought she could wiggle out of this dare easily, the moment she would have been alone with him, being he one of her oldest friends.

"And how would you exactly expect me to avoid my penalty, then ?" He points out defensively.

"Hmm, just ... jack it off, maybe? As i said, i can give you some more time, if you need it ..."
