Foot smelling contest with 3 czech girls

Megan is having some girl friends over at her place which she shares with a guy - Charlie. Megan herself is pretty dominant and she got Charlie to cover part of her rent and to have kind of a slave at her disposal. Charlie loves feet and especially smelly feet so it's really a win-win scenario - Charlie gets Megan's feet and smelly gym socks and Megan get pretty much whatever she wants :). So all 3 girls are now at Megan's place, waiting for Charlie to arrive because they want to have some fun and they made up this foot smelling contest thing - Charlie will have to smell their feet and socks and decide who's feet and socks smell the worst right now. Megan is experienced with this but the other two girls are not and it will be a new thing for them. Hopefully they'll love it and do it again. Charlie will enjoy it for sure!
