You, my little brother, has for a long time been fascinated by my long, dark armpit hair. It especially intrigues you when it's sweaty and smelly. You steal my t-shirts now and then so you can sniff my stinky musk real close. I'm become aware of your fascination with my sweaty, stinky armpits and I feel sorry for you. How will you find someone that will be okay with this weird, disgusting kink of yours? Even thought I find this gross I kind of want to help my perverted little brother experience what he is longing for. So I let you sniff my hairy, musky armpits straight from the source. I want you to inhale the stench. I want you to have my hair tickle in your face. And even though this is sick, especially with your own sibling, I kind of like it... I want you to continue by licking and sucking my armpit hairy clean from the sweat. Maybe we can make a deal and you can lick me clean always instead of me taking showers...? And if you behave you might get to place your cock in my hairy, smelly armpit one day, and maybe even spurt your cum there... Includes: degrading, humiliation, dirty talk, sweaty armpits, big sister, little brother
