Is a hot/warm wrinly penis as soon as you get out of the shower. It HAS to be LIMP to be a shower boner!

A Cadet shower-room boner is the raging hard-on a cadet gets when he hasn't taken care of his morning wood.
I had a Cadet shower-room boner this morning, but -- no worries -- another hot cadet sucked my dick!
