Jerking off with two hands

When two males stand facing each other, lining up their dicks so that they're rubbing shafts, then they both grab the double-dick with their respective hands, linking fingers, and jerk off - giving the effect of two opposite-facing trains in an underground station.

A sexual act in which two consenting males (of legal or illegal age) sit on their hands until they become numb. When both achieve sufficient stiffness of their penis they simultaneously jerk each other off until the point of ejaculation. At this point both loads of cum are then blasted into each others faces.

This game can be played by oneself, but is usually referred to as the strange in such cases.
