Join him in the same shower.

From Create Your Own Story

You move right up next Shaun and he quickly backs away shouting.

"What the Hell man!"

You shrug and say.

"Saves water this way."

For a second he looks like he's about to shout at you again but he suddenly sighs and joins you. The two of you take turns showering and you notice that Shaun has both hands covering his dick the entire time. What do you do about this?

Ask Shaun what he's packing

Try to move his hands away yourself.
