Your girlfriend is gone.... You should take this opportunity to do the things you want to do to your girlfriend's best friend's feet.
I've been with foot boys and it makes me HOT to see you stroking for my feet.
I encourage you to jerk it to my soles, and get more an more turned on as we continue. I start lip smacking, touching myself, then start to make myself cum, hoping you will cum at the same time as me.
