Become the center of attention

The girls start to eye my naked body. I become embarrassed and cover my crotch with my hands.

"Hey, c'mon dude," Becky snaps at me. "If you're gonna get nude, then get nude!"

"Yea John," Samantha chimes in, a cheeky smile on her face. "You gotta commit to it."

"I mean," Susan says. "You were fine with going nude before, right? So you might as well."

Unable to refute them, I let my hands fall to my sides, exposing myself fully to the girls. They immediately resume their intense staring at my groin. To my horror, my penis begins to stir and grow.

"Oh my god," Becky gasps, a wide grin spreading across her face. "Why are you getting hard??"

"You're really liking this, aren't you?" Samantha says, folding her arms.

"I always knew you were a pervert," Susan says with a smirk.
