Answer: Tromboning, is when a girl or guy (depending in what situation you find yourself), licks your anus and masturbates you at the same time.
my friend told me about her desire to trombone her boyfriend, I`v never heard of this before ! she said he was reluctant to let her do it to him, just wondered if any other girls have done this to their bf
