They order pizza

Melissa pipes up, "Uh, Aaron?" and gestures over her naked body.

"Oh, right", says Aaron, a bit embarrassed, "I'm so sorry, I promise I wasn't trying to make you go out naked. I was just..."

"Not thinking, I know", replied Melissa. Aaron looked bummed out. Melissa continued, "Hey, it's okay dude. I know you weren't being a perv. And it's not every day a naked girl shows up at your house.", she continued, "If you wanna know the truth, I spent all day naked in school today and walked all the way here naked, too. I haven't had a stitch clothing for many hours. If you're really set on going out, I'd grin bare it.", she paused, thinking her pun wad was clever, "but still, if it's my choice, I'd rather stay here. Today was a very intense day."

Aaron agreed, "Pizza it is then."

She whispers in his ear, inadvertently brushing her bare right nipple on his arm, "Think of it this way: you get a sexy, naked girl all to yourself."

Before today, Melissa wouldn't have flirted this blatantly, but this wasn't the same Melissa from yesterday anymore.

The delivery boy showed up and rang the bell. Ms. Fletcher and Aaron were occupied setting up outside so Melissa opened the door, naked of course. The delivery boy's mouth was agape and his eyes bugged out. He couldn't even manage to speak yet.

Melissa initiated. She grabbbed the pizza and said, "Oh, the money's on the counter, let me get it."

The pizza boy finally spoke up "I-it's on the house but u-under one condition."

"Yeah? What's that?", she innocently asked.

"The guys and my boss are not going to believe this when I tell them about it so c-can you t-take a selfie with me?"

He regretted that right away. Maybe this gorgeous naked girl didn't realize she was naked and would be offended by his 'offer', maybe this was a dare and he scared her. But before he could think of further reasons why this might have been an enormous mistake, she cheerfully said, "Sure."

"Really?"

"Yeah. You're sure you don't need the money?"

"This is better than money."

"Aw thanks", Melissa replied, surprising him again.

She posed for nit just one but three different selfies. He asked her, "And you're sure you're okay with me sharing this with the guys?"

"After today, yeah."

"Must have been a hell of a day."

"You have no idea."

He went to put his camera phone away but Melissa stopped him, "Wait, I forgot something."

She turned around, bent over, without bending her knees and spread her legs slightly. The brazen display was getting her a bit aroused, further opening her pussy for the pizza boy.

"Uh, what are you doing?", he asked, genuinely not knowing why this gorgeous girl was displaying herself like this to him. Not that he was complaining about this lovely new sight.

Melissa responded "I forgot to give you a tip. Now hurry up and shap the picture before the neighbors see up my vagina."

He took several pictures and a video as she wiggled her naked butt for him. Once he was done, she told him "The first set of naked pictures you can show anyone you like. These last, more explicit ones are just for you though, got it?"

"Yes, ma'am."

"Good boy.", she said, "Here's a little incentive for you."

Before she closed the door, she reached down, rubbed two fingers across her pussy and got some if her wetness on them. She put her wet fingers into the delivery boy's mouth and let him suck off her juices. "Bye, cutie.", she said, closing the door.

She brought the pizza box to the backyard and they ate it casually, Melissa sitting cross-legged, exposing her pussy a but mire than normal but not nearly to the degree she did for the pizza boy.

Aaron was wondering to himself, "Was Melissa's pussy that wet this whole time? Was it more open and inviting now or are my hormones making me imagine that."

Ms. Fletcher either didn't notice or simply didn't care to comment on it, instead she started to discuss the sleeping arrangements, "So we've got the hammock out here. It's a lovely night and there still aren't any bugs out.", she gave another option, "Aaand there are two couches in the house, one on the main floor and one in the basement.".

Aaron piped up with a third option, "I have a fold up bed in my room."
