I watched for perhaps a few minutes until the bare assed girl turned to look back and saw me standing in the doorway rubbing my hard cock through my d...nim jeans."Oh there you are" my wife loudly called from a far . The woman stood up pushing the hem of her dress down as the other stood wiping her mouth then they both walked passed me as I headed towards my wife. "Yes.
