Boogers

Aaaaahhh.... yet another satisfying experience. This time, its perfect too. The feeling is like something slippery from your body being removed without any pain and yet, you feel that foreign object coming out without any struggle. And its slightly ticklish.

I think the closest feeling I can describe to you is the pulling out of your pinkie from your slightly runny nose. Because the other description below the waist is not appropriate.

Not too hard and not too soft

And not too watery either. This way, when you pull it out, it gives you THAT feeling.
