A dongademon is a humanoid monster with a large penis, their cocks can be very long, perhaps ordinary looking at first, but their erections can be long, like from 7 meters to a staggering 10 thousand kilometers! Their cocks are hard but flexible and can move around like a snake. A dongademon's dick will not be penetrated by anything weaker than steel, this feature can be used for swordfighting. Dongademons can ejaculate on command and really powerful ones can shoot fire, ice and lightning out of their dicks. Extremely powerful, horny, rock hard perverted dongademons can conjure anything out of their cocks, those dongademons are very rare and are usually the leaders of a dongademon group. Every dongademon is different and there are unlimited possibilities of what powers a dongademon`s cock can possess.
