Balls. Those wrinkly, saggy, salty, prickly, smelly, egg-shaped sacks that hang below my favorite type of meat can make fellatio a job or an absolute blast (pun intended).
One of the most fun times I had when sucking on a pair of balls was when I was when I was over at my fwb apartment. We were doing the whole netflix and chill thing and his roommate had gone home for the weekend, so we were able to actually watch netflix.
We were sitting on his couch and we had started watching Futurama when I laid down on his lap. He had on gym shorts, which was actually pretty comfortable for my head. After a few slaps on my booty, as well as some strong squeeze of my cheeks, I felt something hard pushing against my temple. I decided to keep watching Futurama until his hard-on was legit pushing my head up. I was impressed.
At first, he just pulled down his pants and I sucked on the magnificent sausage pole that shot up and whacked me in the forehand. This was great because I could watch tv and slob on his knob, win win!
