Time is near

For several years I have confided honestly that I feel she deserves a bigger endowed, longer lasting sexual partner who could join us in the bedroom for a threesome. At first she said it would feel like she would be cheating and would not like that emotion at all. We bought very large toys over the years and they get girthier every time. Recently she said she would like to fulfill my fantasy. She kind of bribed me by saying I should learn to ball room dance since she is willing to try a threesome for me. I am very excited for the chance to tag team her and hopefully provide her a sexual experience I feel she deserves and will thoroughly enjoy. Just wondering if anyone else has had a similar situation. Thanks
