He freaks out of course

Jake quickly looked around for his swim trunks, but he didn't see them anywhere. His face turned bright red as he dove underwater to see if they had sank down to the bottom of the pool. Unfortunately they weren't down there and he resurfaced to see his step sister and her friends swimming over towards him. He quickly swam through the water past all of the girls and into the shallow end of the pool. Angela, Erin, Nicki, Tina and Hayley all dove underwater to catch a glimpse of his dick while he swam and they all surfaced and broke out laughing.

"So Miranda, did you know that your step brother has a baby dick." Angela said as she started dying laughing.

"No I don't!" Jake yelled out in a panic and he quickly covered up his junk.

"They why are you covering up now that she said that." Patty said giggling.

"Oh he definitely does. I saw it too. He looked rock hard and it was maybe two inches, if that!" Nicki added.

"Yeah it's tiny. We are talking microdick territory!" Hayley added in laughing.

"So the biggest nerd in school has the littlest penis." Kara added in.

"What a loser. I bet he's never going to lose his virginity, if it's that small. No girl wants anything that small between their legs!" Tina said laughing.

"Not a chance he's going to ever have sex. I knew that before I heard his dick was so tiny!" Kaylee said.

"It's basically a clit! I can't wait for everyone to hear about this. He's going to be more of a laughing stock then he already is." Hayley said giggling.

"I bet he beats off with just two fingers! I think his entire hand would make his little stick disappear!" Erin shouted out.

"Forget that, he probably needs to use tweezers to jerk it. He's hard and it's just two inches. What a pathetic loser!" Angela said with an evil laugh.

"This is just too funny. I always knew my step brother was a loser, but this is just too perfect." Miranda said.

"We should have some fun with him. He's always looking at our body's, why shouldn't we have some fun looking at his!" Hayley added.

"More like fun laughing and making fun of his. He's a skinny, out of shape nerd, with an itty bitty little dick. This is like a gold mine of bullying information." Angela added.

"You are so right Angela. Let's have some fun at my complete loser of a step brother and his little shrimp's experience!" Miranda said giggling.

"It's not like there's anything for him to wear here anymore, so he's kinda stuck naked!" Kaylee added as she laughed devilishly

All of the girls then started swimming over towards Jake again, all of them with devilish smiles on their faces. His heart started to really pound in his chest, as he frantically looked around. He knew that they were going to make this a lot worse for him, but there was nothing he could do. His only options were stay in the pool and hope they didn't make it too humiliating for him. Or he could take off running and leave, but then he would be stuck running around town completely naked.
