Ignore it

You studiously ignore Jake's actions as he masturbates through his shorts. He continues to talk to you, but you find his actions distracting.

Finally, Jake sighs in exasperation.

"Can't you see what I'm doing?" he asks.

"Yeah", you reply uncomfortably.

You glance quickly down to Jake's crotch, where his hard cock is clearly visible.

"So you're not taking the hint?"

"What hint?"

Jake shakes his head at your confusion. You frown at him, and he sighs again. Then, it clicks.

"You want to have sex with me?" you ask in surprise.

"Does that surprise you so much?" Jake asks. "Most backpackers are horny twenty-something year olds. They'll go for sex whenever they can get it."

You don't deny Jake's comments. You already been propositioned on flimsier reasons than this on your holiday.

"So?" Jake asks impatiently.
