Give it back!!
My darling: perhaps we shouldn't have started a physical relationship, since you're married to my sister, but we crossed that bridge and we were both happy for it..... for over two years. I know, I know: we were very VERY nearly caught, and that was terrifying. But I think we both know you are meant by God to be with me, not with her. Either way, I want you back in my life, and I definitely want that dick of yours back in my pussy, mouth and ass. Plus, I want your babies. I will say it again:
I want your babies and I don't want you to knock up anyone else. Ayana certainly doesn't deserve any of that. And I will do whatever it takes to keep her from getting ANY of it. EVER.
You KNOW what I mean when I say that. I want you back. Now. Come back to me, and let's make it permanent this time, and 24/7,
with my sister OUT of the picture. End it with her, once and for all, or I'll do it myself. You know what that means, too. End it NOW. You belong to me, and I want what's mine: come put it in me!
