There are two additional reasons why I like to have him guide me into her. It gives reassurance to her that her husband is completely supportive of what she is about to do. Guiding in and clean up are the most dramatic gestures that he can make to demonstrate that he completely supports her choice to take control of her sexuality.
I think one of the greatest things about dating or bringing an older wife into the lifestyle is that it returns a Man-Woman relationship to her life that has been missing for a long term rather than the Husband-Wife/...... relationship. I bring passion, romance, and pleasure and when I am with her my attention to her is that of a man who wants her and demonstrates that with constant touching to constantly keep the sexual electricity between us going-not about whether the patio paving stones need to be replaced.
Finally, while my primary focus is her I want to do anything that increases the erotic excitement in the triad. So, creating an experience for the cuck that allows him to experience the heat rushing to his head as he is filled with shame and excitement generates more erotic excitement for all of us. Just as the first time when we are standing naked together and she guides my cock into his mouth as he kneels before us to prepare me to enter her. That moment when she fully revels in the idea of two men dedicated to her pleasure is an incredibly empowering moment for her and exciting and erotic for he and I.
And it is so much more fun than picking patio furniture!!
