Your naive Step-Aunt has invited you over after the gym to do a smell check with her new leggings, she's also worried they are sheer and show too much. A sweet church going woman like her dresses modestly, so it's important she's decent. When you arrive you immediately notice her full hairy bush and big round ass on display and when she gives you a hug you smell something nasty, but nice. You lie and tell her you don't see or smell anything, but that isn't enough she has to make sure. Bending over, spreading her legs, having you press your nose against her asshole and pussy to sniff and even asking if you see her butthole winking. She's so naive she doesn't even notice you discreetly stroking your dick. Her smell is so strong you can't help but cum hard for your Step-Aunt.
