Is it normal to smell my cousin's feet when she was asleep?

I am 30 and still live in my parents house. Last weekend we had a family gathering and my 16 year old cousin came with her parents and brother. We slept in different bedrooms, but next morning I crept sneakily into the room and put my nose as close to her feet as possible without actually touching them (because I didn't want to wake her), and took a big inhale of her toes as she was laying sleeping on the bed. Her toes smelled a little sweaty but a little sweet too.
