Love my butt
My wife and I use lube most times we have s**, allows us to go longer and to do it more frequently without any soreness on her part.
She has gotten into the habit in certain positions to get lube all over her fingers and ram one into my ass as I get close to o*****.
It is by far the best feeling in the world. It focuses so much attention on that area that I maintain that "just about to come" feeling longer until everything explodes.
If you guys haven't tried it, I'm telling you, a skilled finger can be the best turn on you have had in a long time.
