When a man gives himself a prostate orgasm and ejaculation by laying on his stomach and flexing his ass muscles up against his prostate to stimulate it. This can be done when the penis is either erect or flacid, and nothing needs to go inside your rectum. It's like bottoming solo.
Luke doesn't jerk off, he flexes off. Why can't you masturbate like everybody else does, Luke? Why do you have to figure out ways to have better orgasms and keep this shit a secret, Luke? I want to flex off too. Wow I bet Luke is great in bed, he knows all kinds of secret tricks.
