Ooh, a lovely mix of helplessness, perversion, and breathplay. Tightly restrained in the girls' locker room, utterly incapable of getting free. Left to put up with the smell of their stinky socks, mouth probably stuffed with another one underneath the gag. And then a bag full of their rancid, sweaty, dirty socks pulled over your head and tied off, forcing you to take the aroma in as your air slowly runs out, depending on one of the other girls to give you fresh air every so often.
