Black Drone and Frank's ex-wife screwing

Drone Sex is self-explanatory, just sex with drones. It is seen in WHY DRONES SUCK, where Black Drone has sex with Frank's ex-wife (white drone). Even though the drones don't have any genitalia and are just rubbing against each other, Black Drone still somehow ejaculated; Frank exclaiming "Wow, that's a lot of cum." Somehow, Frank even mentioned Alaskan Pipeline, although this was seen nowhere.
