At the same time, exercise, the left hand to pick the fine cup; if you use the left hand to collect fines, you have to lie on the right side of the boar, left hand to grasp the penis, the right hand to pick the fine cup.

Once the boar starts ejaculation, the hand should immediately stop the kneading and just hold the penis. After the ejaculation, it should be pinched immediately to stimulate it to ejaculate again.
