Penny has two secret fetishes, the first is quite normal she suspects, but the other she's convinced is decidedly strange and kinky. Often she wears a loose top and gives a quick peep at her firm ebony breasts and erect nipples, she even posts nude selfies online displaying herself, but her second fetish is a confusion to her, because she's never met anyone who gets turned on by hairy armpits like hers... that is until she meets Joan and Tom, and suddenly her life begins to spin out of control!
