Wank n’ Spank
When you are giving your cock a vigorous wank and you have a sexual partner lovingly, but repeatedly and firmly, spanking your dangling ballsack at the same time. Ideally, the wank and the spank are performed in synchronized fashion.
I was giving myself a old fashioned wank when my girl walked in. She helped finish me off with a wank n’ spank. My balls are sore as hell.
