I used to let My Wife meet Her. Main Man ( BBC ) on Her own, at first She came Home of a night out, which led to staying the night, and on some occasions, She would be dropped off at the apartment, He used, of a Friday, and I would pick Her up on a Sunday Morning.
But this was very occasionally.
And usually meant Her boyfriend had arranged something “ Special “ for Her like, some of His mates or some Other Lady friends for Her.
Mainly though It was just Her and Him/ Them.
I always after dropping Her off, Had the butterflies in my stomach, a mixture of fear,wanting Her to have a good time, will someone find out etc etc..
As over time technology improved, Amy phone would ping,and a nice little clip, of what was going on with Her ,would appear.
It was always very Hot.
