Armpit
From Voyeurweb's Wiki about Sex
The armpit is the cavity beneath the junction of the arm and shoulder. Female armpits are subject to armpit fetish, armpit voyeurism and armpit fucking. Armpits produce a strong odor and grow hair. Almost all women keep their armpits free of hair by shaving them frequently. Armpits tend to develop a lot of sweat and might turn smelly. In order to prevent nasty smell, people use deodorants. Armpits which have hair are called hairy armpits.
