Pretend she's worried about their relationship

She came up with a plan. First she just had to get some ammunition. She texted Sara again.

"Wow, only five inches? That's tiny! Is Josh into tiny dicks or something?"

"I don't think so, but I've never asked him."

"Check his porn! See what sorts of things he searches for online."

There was a little bit before her reply. "He likes them big."

"Damn, that sucks."

"Five inches isn't that small though, right? Just a little below average?"

"Are you kidding, it's tiny! Mine is twice that size!"

"I've always been worried I'm not satisfying him in bed..."

"But now you're certain?"

"Yeah, and I'm afraid."

"Afraid of what?"

"If I'm not good at sex... what if he leaves me?"

"Oh, that's pretty heavy. You think he'd leave you just because your dick is minuscule? How does he act when he gives you blowjobs?"

"He's never given me one."

"Oh, that could be trouble. I heard that's the first sign of a breakup."

"Really?"

"Don't worry, I'll talk to him. I'm certain he'll see the light. I might end up yelling at him, so go shopping or something once he's home."

There, she thought, closing the chat, now she just had to wait.

Eventually, she got a text saying that Josh was home, and Sara had gone out. She decided it was time, and walked over to where the pair lived, and knocked on the door.

Josh answered the door, "Oh, Anna, come in."

Anna stepped inside. "Is Sara here?"

"No, actually, you just missed her."

"Oh. There's something I want to talk to you about."

"What?"

"It's about Sara. She's afraid that you're going to break up with her because she's not good enough at sex."

"I... what? I wouldn't break up with her for anything, even if there was no sex! And she isn't bad at it!"

"She's seen the porn, you like big dicks."

"Well, yeah. Everyone does. But I wouldn't dump her just because she's small."

"You say that, but I've never seen a man stay in a relationship where he isn't sexually satisfied. I don't want you to hurt her so..." She was nervous, she had never done this before, or anything like it. "...so I'd like to make a deal. You take care of her, and I take care of you."

"...What?" She had a feeling. Now was the time to act.
