A transition from napping/cuddling to sensual foreplay, followed by passionate, (rough) sex... aka, I really want to hold you and be close, but let's go to pound town on the fuck truck.

Simply put, it's a cuddle that turns into a fuck. And it's really good. Also referred to as SF, or SFing.
Babe, I need some snugglefucks.
