Pistonfuck

Pistonfuck
Tier	3. Immortal	Type	Steel
Variety	Pummel	Speed	Instant (1)

Pistonfuck is an essential face-fucking stunt emphasizing superhuman speed and lightning-fast, thunderously forceful thrusts—and a counterpart to pistonsuck.
When You pistonfuck myself or another exceptionally fortunate slut, a lightning-fast thrust drives most—ideally all—of the Godcock's glorious length through my face faster than the eye can track. The invincible tip plunges it down my cunt-throat to SLAM my cervix, only to immediately rip it back out with blinding speed. Both the rebound off my cervix and the minimized sub-frame contact with my cervix heighten the force exerted against it!
Pistonfucking isn't limited to a single thrust, with the term implying dozens of lightning-fast hammers every single second—if not hundreds or even THOUSANDS. This informs the stunt's name, as the impossibly-fast thrusts resemble the furiously roaring piston of an engine. ♥
