When the leader of the sexual act called The Big 3 has anal sex with one man while another sucks his balls. They both swallow the leader's jizz
Dwyane Wade roped Lebron James and Chris Bosh into The Big 3. James, being an inferior athlete and leader, receives the anal, while Bosh, the desperate to be famous and successful, sucks Wade's balls. They both swallow the jizz, James, because he wants to inherit Wade's franchise carrying abilities and savors the flavor, and Bosh because he wants to inherit Wade's marketability, and because he likes to smack it around his mouth in order to make Wade happy.
Commonly, Bosh will give James handjob after handjob during said act, as well as have James spit his share of Wade's jizz into his mouth
