Play it cool

"C'mon guys," I say, trying to play it cool despite me blushing. "I'm a young fellow, I can't help it."

"Yeah, we all know you can't help it," Becky laughs.

"I figured you'd get hard at some point," Samantha says. "I just wasn't expecting it to be so soon."

Susan sits herself down into one of the beach chairs. "I guess we can save the teasing for another time then," she says, yawning as she puts on her wide-rimmed straw hat.

"W-what teasing?" I ask, my curiosity piqued.

"Oh, y'know," Samantha replies, turning around and pulling on the hem of her one-piece's butt cheek, releasing it with a soft snap. "Just girls being girls."

I gulp nervously. Looking down, I see that my cock is now standing at full mast and practically parallel with the ground.
