looks like even AI can't help but notice the connection between the balls!
Here you can see very nicely what happens when soccer moms stand on the sidelines - pants dirty!
This is what I think might happen. Sophia's pants get splattered with mud and she goes to clean them in the locker room showers. Later, the boys arrive and see Sophia cleaning her pants wearing just a thong and her top.
Sophia notices them and starts shaking her ass.
This is the animation we see.
Dylan joins in and finishes the whole thing. But having argued along the same lines (in the conversation in the car on the way there) as his sister, that she deserves to have fun, Dylan watches for a while himself before calling it a day.
On the drive back from the game, Dylan remains silent about what he saw on the cDylan route, on the other route he forces/convinces Sophia to admit that she liked the “attention”.
This could be used to get Sophia to agree to another photo op with Dylan later.
