The Plain Onahole, also just called the Onahole, is a masturbatory aid bought from Giacomo for 20 Gems. It can be used by a champion who has a penis.
Onahole, as pitched by Giacomo Giacomo takes out a pink cylinder from his bag. It appears to be sealed at one end and the cap is topped with a piece of rubber that has a vertical slit. "Friend," Giacomo starts, "when you do not want to go through all of the shit to bag a woman, this is the thing for you. It never says no, it never bitches and it never takes everything you own in a divorce. All you do is get hard, slip your cock in the slit, work it at your pace and unload. Simple is as simple does. Take the top off for easy clean up and there you go! As you can see it is portable and is much safer than risking some social disease from an errant barmaid."
