You were helping zecora with some things you Later come to help her with one last thing which is to test out a potion, you feel something in your crotch and zecora tells you she finds you actractive and notices how you stare at her body she does the thing on the picture

And you unleash your enhanced erection on her, rutting her from behind like an animal while she speaks in her native tounge and for some reason it made you fuck her even more, eventualy you were close and zecora knew it and she begged you to let her bear your children and even if you wanted to pull out, her pussy was gripping you tight so you let loose and unleashed your seed inside her womb...and thats how you met your wife!
