Snugglefuck is when you only planned to cuddle or snuggle and you end up fucking because all the friction in your pants caused a fire that needed to be put out.
Girl! Matt invited me over to snuggle and watch movies and before Titanic sunk it turned into a snugglefuck session..
Enter spooning position, eagerly kiss the neck of your partner while rubbing the thigh gently with the palm of your hand. Thus opening her sexual pallet. Firmly press forward on her leg, slide penis approximately 3-6 inches inside of her, grabbing tightly onto her hair and railing the fuck out of her. Thus creating the snugglefuck effect
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.
