I had this discussion with my ex-wife when we were married; neither of us see it as gay. she broached the idea by saying if you are going to share your wife and then be ok with her taking on a regular lover and accepting the idea he fucks her better, she needs his cock then you are submitting to him already, then your role should also be to help please and submit to him to complete the circle as a couple doing this together. Its not gay, its submission to a better man and lover who fucks and pleases your wife sexually as an addition to you both as a couple. Sucking his dick sends both of them a strong message and she liked feeling satisfied she chose an alpha male to fuck her together that she can develop feelings for and I understand and support her by encouraging and helping him fuck her pussy like she needs and deserves. Womens needs for other alpha males to breed and fuck is strong with some and needs to be encouraged to prevent cheating, control the situation and make them happy and satisfied with the husbands support and beta role, making way for them to breed and fuck often and their cum inside her womans pussy along with their larger hung cock is the top of the foundation. By sucking both and him you lay the bottom of the foundation for support, acceptance, comfort and encouragement of facilitating them both to mate and breed more frequently.
