"N...no, please stop that, Madame Madeline." you reply.
"What's wrong, dear?" Madeline asks. "Aren't you going have sex?"
"Well, I do, but I just can't, y'know." you respond as you look away. "Look, I don't want to be rude to you but to tell you the truth, I have my girlfriend, who is the host that you possess and transform into. And more importantly, I don't want to cheat my girlfriend neither, so can I have her back please?"
"Well, darling. It seems like you're an honest and sweet boy after all. I think I like about you, handsome." Madeline smiles and then walks toward to you and hold your face. "Very well, my dear handsome. I shall give your girlfriend's body back. But first, let's us kiss each other."
With that, you and Madeline kisses each other as you can feel her body is changing. Slowly, her body turns back to your girlfriend's form. Once the body is back looking like your girlfriend's old body that you once knew when you were first met her and still naked, she opens her eyes. "Honey, I'm back now." she speaks with her normal voice is also back to normal. "Now I know why I fell in love with you."
And then, you both continue to kiss as you welcome your girlfriend back. After the long kiss, you look at your girlfriend as you have the thing just to make sure. "Babe can I ask you one thing?" you ask.
"Sure what is it, hun." your girlfriend says as she holds your face and looks at you.
"Is Madame Madeline still in control?" you asks just to makes sure.
