After throwing the ball, the girls decided to take a break because they have been playing for an hour on this sunny day and it is getting difficult for them.
They want to rest, they take off their sneakers, they look for a time break, and then they see how wet and sweaty their socks are.
mm..that smell entices their little friend who gets intoxicateed by the smell of sweaty feet and socks
He comes, gets down in front of them and starts sniffing and smelling their sweaty socks, the girls are having fun while he enjoys the intoxicatinng smell
