When a female/male kneels behind a male while he is standing and has an erection. The kneeling person reaches between his legs and grabs his erection like a microphone, pulling it down, then sticking their thumb up his ass with the same hand. Then they squeeze their hand tight, not unlike that of a gas pump handle.
