Only men have penises

She noticed the rule saying that, aside from a few exceptions, men have penises, and women do not. She had never been in a relationship, for a number of reasons, but had always heard from her friends about how much they loved sucking cock, and how delicious cum was, and how their boyfriend's cock was the most delicious. She had always wondered what it tasted like. "Both men and women have penises." she edited the rule.

"Yeah," she said aloud, "as if it were that easy." She glanced down at her pants. She didn't really think it had worked, but there was no harm in checking, right? She unbuttoned her pants and pulled them down, and was shocked to see a flaccid penis, and more shocked to see that her underwear was clearly designed to accommodate it, as the top was higher than usual, and it was made to press her penis flat against her stomach. Curious, she went to the Victoria's Secret website, and looked through their underwear. There were three kinds of panties, the kind that she was wearing, the opposite, where the dick was pushed down, which concealed it a little better if you were wearing nothing else, but which seemed like they would become uncomfortable if you were erect, and a kind designed with a hole for your penis to fall out of, and a cloth sleeve around it, although some just had the hole. These seemed to be considered sexiest, surprisingly. She supposed that if all women have penises, nobody would think it's weird.

Enough fooling around though, she thought, it was time to taste her penis! She pulled her panties off as well, and tried to bend towards it, but even though she was fairly flexible, she couldn't get anywhere close to it. She rubbed it for a little bit, and it shot up. She almost just kept going, but she stopped herself, and tried bending down again. She was closer, but still wasn't going to be reaching it any time soon. Maybe it was the length? The models she had seen all had fairly long dicks, but hers was much shorter. She quickly found a ruler and measured it. it was about four inches, or ten centimeters long. Was that normal for people who weren't models? She decided to text her friend Sara, and ask her.

"Hey, Sarah, I was thinking of getting you a present, how big is your penis when it's hard?" she typed. There, she'd think it was a pair of panties or something.

The reply came fairly quickly, but shocked the hell out of Anna. "Eight inches."

What the fuck?! Sara's penis was twice her own? She doubled the length of her penis in her mind, and was amazed at how big it was. Maybe she should use the rules to try to change this, make her penis bigger, and Sara's smaller. Or she could just make everyone's penises bigger, Sara didn't really do anything wrong after all. Although... what if Sara is just lying? Eight inches seemed like an awful lot... maybe Sara was actually even smaller than she was.
