The act of two guys having sex, and the position they're in is that the top one is fucking the bottom, while the top jerks them off. Unlike similar situations, where the bottom does some of the work to make them cum...the top does all the work in order to make both of them cum.
A typical practice of this is when the top not only continously jerks off the bottom, but cum deep in their ass as much as possible. Usually trying to sync up both for peak pleasure.
1: Hey honey, how do you wanna fuck tonight?
2: How about we do a dick-hole pickle jerk?
1: That sounds so hot...so who's the bottom?
2: You already know the answer...( ͡° ͜ʖ ͡°)
