the Slip n' Slide, is when you cover your bed in a plastic tarp, piss and shit all over it,and then have sex on it rolling all around in the slippery piss and shit.
When I was was five, my uncle gave me a slip n' slide, and I said this is not the same kind of slip n' slide my friends have, that's the last time I ever saw my uncle.
The act were a women will sit at the end of a slip n' slide, legs wide open. The man then proceeds to go down the slide eventually penetrating. Be weary though one wrong move and your dick will fold like a recliner.
Joe: Did you hear what Jim did with Pam.
Rylee: What?
Joe: They attempted the Slip n' slide.
Rylee: YIKES!
While our lifespan is the number of years we will live, our healthspan is the number of healthy years we will have and our sexspan is is the number of years we will continue to be healthy enough to continue having an active sex life.
