I had this fuck buddy who would use clinical terms during sex. He would repeat how he liked sucking on glans of my penis, licking my scrotum, sucking on my testicles, and flicking of my frenulum with his tongue. Several times he asked me to insert my penis into his anus, in those words.
I have given--and received--millions of BJ's in my lifetime, but I swear I've never seen anyone enjoy getting one more than Farmer G. I thought he was going to die a couple of times.
