You want her to have a relationship

"Molly," you say softly, "I think I would like the full experience. There's nothing for me if you are just fucking guys for fun. I want genuine feelings involved."

"But, won't that be hard on you? I don't want you to feel neglected," Molly responds concerned.

"I won't! When he's with us, we can almost roleplay. You give him as much attention as possible and I will be your neglected third-wheel. And when we are alone, you and I can take a break from it all and spend quality time as husband and wife. I just need to feel that rush from seeing you with another man in more ways than just sexually," you explain.

You hope that what you said makes sense to Molly. You also hope she's willing to try it. She takes a noticeable deep breath before speaking.

"Ok, I think that actually sounds like fun. It's intense, but thinking about it makes me feel...really good. I never realized how into this I was, but...I think I need this as much as you. I do have one condition though," Molly says.
