Sneak to Smell Her Feet

Abby is sitting on the couch reading her book when Anna comes home right from the gym. Anna tells Abby about her long vigorous workouts she did, including an 11 mile run. Her feet are achy and sweaty, so Abby offers her to prop them up and have her rub them. Anna is so deep into her phone, she does not notice that Abby is secretly sniffing her feet. Abby makes sure she isnt looking and sneakily takes deep sensual inhales. Abby is getting so worked up, she can barely contain herself! What happens if Anna catches her?
