Mother then daughter
A few years ago I had s** with a woman 20 years my senior. I used to f*** her bareback each week. I once suggested to her that I would love to f*** her daughter, so she arranged for that to happen.
The daughter arrived at the house, whilst the mother was downstairs, and I f***** her.
Thing was - each week I would take it in turns to f*** them - and I was going bareback with both of them. The mother would say "Don't tell my daughter we go bareback," and the daughter would say "Don't tell my mom we go bareback."
It was great fun whilst it lasted.
never had a threesome with them though - that would have been f***** up.
