Superb demonstration of "pisswanking". Fullbladder discovered this technique several years before puberty ejaculating started and has continued to enjoy masturbating urine spurting ever since. With practice there can be dozens of urethral pee spurt throbs that are similar in sexual pleasure level to sperm spurt throbs, and lots more of them. A variation of this technique is pee spurts first, then sperm spurts, then more pee spurts after ejaculating while urethra is still very sexually sensitive.
