NOTE: We take no responsibility for any crotch muscles strained while impersonating such intense thrusting.

1D are no stranger to a nicely choreographed routine that brings all attention to their groin region and as if touching themselves on stage wasn't enough, Niall has decided to share a behind the scenes action video of Louis, Liam and Harry getting jiggy to C'mon C'mon.

"This is what happens in vocal rehearsals haha, Liam's signature move #TheJoe," Niall tweeted.

We can't say we're surprised to hear that the Paynis is behind all this, in fact we're pretty appreciative. Especially after seeing the accompanying arm movements Captain Sassypants has thrown into the mix.
