when a man pinches the head of his dick just before climax in order to build pressure before releasing the head and flexing his dick to achieve a cum shot with amazing distance.
my girl was laying on the edge of the bed while i stood beside it and fucked her. just be for i came i backed away from the side of the the bed so i might give her a good cock blast. i surprised her when i hit her in the bottom of her chin from five feet away.
man: Here it comes! AAGGHHH
woman: Oooooo i love how your cum spashes off my face when you cock blast me like that!
