I come home after working out, I am so sweaty and smelly. I catch you watching me and you insist on smelling my armpits, you love it. You then want me to lick my own armpits for you, you love it so much you start to get hard. I am shocked it turns you on so much, but decide I want to make you cum with my armpits. I start instructing you to stroke to my armpits ending with a cum countdown.
