Doing a chick doggy style, then both laying down flat, male on top of her while continuing to stroke. Not unlike riding a surrfboard in a face down horizontal position.
I was strokin that girl from behind for so long I got tired and had to finish by surfboarding her.
I like surfboarding so I can mash my nuts between her thighs while I'm fucking her in the ass.
A sexual move where a man rests his penis between a woman’s labia and glides back and forth without penetration. The grinding pressure can make her gush or squirt — creating a literal “wave.” The name comes from both the sliding motion and the wave-like effect.
She squirted so much during surfboarding, it was like catching the perfect wave.
Slurboarding is what happens when you drunken type on any kind of keyboard, full size or touch screen. It's the equivalent of slurring your speech when drunk.
