Pretend to be a nudist

Tom: (What if it's urgent?) One Second!

Tom closes the guest room, runs into the bathroom, grabs a towel, covers his penis with it, and answers the door, only to find his friend behind it.

Tom: Hey, Carly.

Carly: Um. Is this a bad time?

Tom: No, I'm just... You know that nudist lifestyle?

Carly: Uh huh.

Tom: Well, I thought I'd try it out while that lady's asleep.

Carly: Oh. Cool. Hey, mind if I come in for a bit?

Tom: Go ahead.

She comes in and sits on the couch as Tom leans on the kitchen island to her left, still holding the towel down.

Tom: What's up with you?

Carly: Not much. Just, needed a rest from that long walk home.

Tom: I get that. Need a beer?

Carly: Yes, please!

He gets her a drink from the fridge while still holding his crotch closed, and then he leans on the island again as Carly drinks.

Tom: Another tough one?

Carly: You could say that again.

She looks at his crotch.

Carly: ... You know, we're all friends here. And, I've seen plenty of weird boners on porn sites. You can throw that towel away, if you wanna.

Tom: Yeah, but I have a, uh-

Carly: An erection? I don't care.

Tom: If you say so.

Tom throws his towel off and Carly almost spits at the sight of his 7 inch penis. She keeps deeply staring at it.

Carly: Dude! That thing's gotta be at least 7 inches!

Tom: Sure is.

Carly: I wonder... Never-mind.

Tom: (What was she thinking?)
