I dared my wife to do this last year as we were sunbathing and I was expecting two friends to arrive.. She was in her
bikini, and sure enough, when I greeted the guys, and we went around the back for a beer in the garden, she said 'hi' and said '..would you mind if I stripped to sunbathe?' ..the guys were aghast as she took off the
bikini in front of them and lay down again.. All afternoon she just lay and walked around totally naked in front of us.. My wife is well waxed and smooth, so she hid nothing from the guys as she was oiling up!!
Towards the end of the summer, we did this again just with one of the guys this time who got to rub tanning oil over her..
