I enjoy giving and receiving. My wife has perfected the art of oral servicing at both ends. Since I started shaving my balls, a few years back, she includes them in her time down there-servicing Big Al and the twins. I had a revelation one day to shave inside the crack of my butt ( didn't have much hair in there, but yeah, there was some). And when we have foreplay, I always go down on her first, then she me, starting with her hand. I gently guided her hand down further south "below the border", to my bumhole, she freekin LOVED it. (of course, I thoroughly washed!) She jumped down there, playing like a 2 year-old in a sandbox, rubbing around it, probing with her fingers, and sucking and licking on it. Sends me to the moon.
