Stinky armpit licking smelling

It's so hot! I've been out side all day working in the yard, sweated off all my make up my hair feels wet and sticky, soon as I walked in my young horny girlfriend begs to smell me, and I let her. I'm a lil embarrassed but she doesn't complain and next thing I know she's kissing my sweaty pits, and giving it long tongue dragging lips with her pierced tongue. Licking up all my smelly BO. It tickles and I love it.
