Serenity is just a very hot 18 yo girl who just discovered foot fetish, and she is the type of girl who really sweat a lot, so she does not really need to wear the same pair of socks, or the same pair of shoes for a very long time to smell a lot. She could wear a pair of fresh socks out of the laundry in the morning with her sneakers on for only a few hours, and they would be smelly as fuck with that very hot weather of Bangkok! Just imagine when she is deciding to wear the same pair of socks and shoes for a few days, just to please us? It could just become a nightmare for a foot sniffer, but I also had no choice to sacrifice myself since I know you guys are totally into it!
