Like air guitar, but with sex.
Yes, this is safe for work but not for dignity. Watch and enjoy…or go fetal with sympathetic embarassment, as these all-too-obvious virgins compete for the glory (?) of being named Best Air Sexer. Surely here is captured the Zeta Male‘s finest moment; my particular favorite is the one who mimes turning the pages.
