You never know, the soccer team might be a freaky secret sex cult, and one mom might be expected to 'cheer' the whole team each week. And what do you know, next week is Sophia's!
Or not. I think more likely not, unfortunately.
However the teacher seems to be into domination (of the giant douchenozzle kind, but still), so all hope for freaky stuff is not lost yet. If he wants to humiliate her, some public stuff might happen. And then there's the movers, and the 'let me grope you in a public park so we can give the hobos a boner' sister. So, who knows where it's going to go.
(A man can dream.)
Edit: forgot about the gym guys!
