One of the hardest things , at least or me to do, is to jack my self rock hard, throbbing and bobbing in the air as I walk to the toilet hard and then piss and keep the hard on. Other tough thing for me is to edge when I need to pee. Third is I have tried to combine the two, jack myself rock hard, piss and slow stroke my pissing cock and then...cut off the piss flow and jack myself right to the edge and control the outcome as I am never sure what will happen , shoot cum only and force piss or piss hard and have the cum drool out after, both have happened. What can I say, I went through a phase, lol.
