Easy
Your life was meaningless in this magical horse land. Everything just seemed too perfect. You had financial security, a great sex life, and you could drink yourself silly without being thrown out.
In a dark and gloomy bar, you the human were drinking down a pint of lager. You wolfed down this alcoholic beverage with gusto. You simply raised your hand once you were done drinking your beer. A grey, old bearded stallion poured you another pint. You proceeded forth to drink your new beer.
Once you were finished you raised your hand again, to order another beer, and then another, and another, and another, and so on. Just when you were about to raise your hand to order yet another beer you felt a soft hoof touching your hand.
You turned to face whoever touched your hand to see that it was the beautiful white unicorn known as Rarity, who was looking at you with bedroom eyes. Because of course, she was. You were incredibly drunk, it looked as if she had two heads. Your vision was blurry in general.
“Anon, darling. I've been looking all over for you. You’ve had enough. Let's get you home,” she said in a concerned tone.
“Rrrrrr...errr…, Rarity, I-I haven't been at home for months.”
She tilted her head to the side curiously. “What do you mean you haven't been at home for months?”
You sighed deeply. “Everyday I end up sleeping with somepony, and staying at their home for the night. Mares are just too easy. I bet I could end up sleeping with you right now even while I'm fucking drunk.”
“Why I never!” she said, glaring at you angrily. “That's not true! Us mares are sophisticated creatures that are not so easily swept up.”
In response you simply pulled out a carrot from your pocket and presented it to her. “Oh my, darling. You are quite a charmer. Do you want to go back to my place… and…. and---” her eyes widened in alarm. “Oh, Celestia! You’re right! We are easy.”
“You see? I-I don’t even need to really try. All I have to do is give you a carrot.”
“Well, carrots are delicious.”
“Giving a pony a carrot should not mean I get automatic sex. I even slept with Princess Celestia and Princess Luna by simply giving them a carrot each. They even made me immortal, they love me so much.”
“I don't know what you're complaining about. Many if given the chance would even kill to sleep with Celestia and Luna.”
“Yeah-yeah, whatever bitch. Let’s go back to your place. I feel so depressed. I need your lovely mouth on my big fat cock to suck my miseries away.”
“Anything for you, my darling.”
“And then go fucking make me a sandwich you fucking bitch!”
“I certainly will, darling.”
You buried your face into your hands and began to cry. “I was even a sexist bastard there, and you still want to fucking sleep with me? Am I playing life on easy mode or something? Women in my old world would fucking slap me over what I said to you.”
“Well, I do like a rude barbarian such as yourself,” in answer you stood up, and then unceremoniously slapped her on the ass. “Oh yes. Slap me again, darling.”
With that, you and Rarity left the establishment. However, you needed Rarity to keep close to you to stop yourself from falling over. By your drunken prospective, you seemed to be teleported into Rarity’s home.
You don't know if you passed out along the way, or something. You did have a vague memory however of smashing up her home with a sledgehammer out of anger. What's even more insane this seemed to turn Rarity on even more as you heard her shout. “Dirty boy! Dirty boy! Dirty-dirty-dirty!”
Tears streamed down your face, despite the joyful feeling having your long, thick cock being sucked off by Rarity. You were lying upon your back upon her bed, while she lay between your legs sucking you off.
“Every night… it ends the same. No matter what I do. I even have a magically enhanced dick to give mares tender loving,” you said in a low voice.
Suddenly, a dark sinister thought crossed your mind. You possibly could even kill Sweetie Belle in front of her, and she would still sleep with you. A cold shiver went down your spine from the dark thought. You might have some degree of mind control over these ponies, but you could not bring yourself to cause pain and suffering to them. Even if, perhaps such a cruel action would actually break the control you have over them.
It's a moral dilemma with no easy answer. Do you commit an atrocious action to set them free? Or do you take advantage of them with your James Bond level of seduction? You decided to take advantage of them. In this particular case it seemed like the lesser evil.
“Rarity?” you spoke softly.
Rarity lifted her head and released your member with a loud pop. “Yes, darling?”
“I love you, Rarity,” you said softly
“Get out of my house! You filthy ape!” she said, pointing her right hoof at her broken bedroom door.
You gasped in joy. “Rarity! Are you now free?”
“Free? What are you talking about, you fat pig?”
Against your better judgement you pulled out a carrot, and presented it to her. “Oh, I love you Rarity.”
“I love you, too darling,” you dreaded those words she replied to you with.
You put the carrot back away into your pocket and said ‘I love you,’ again.
Rarity glared at you angrily and shouted “Get out of my home! You dirty ape!”
You gave her a warm smile, and you happily staggered your drunk an ass out of her home. It seemed you have finally freed Rarity from mind control. The mares were not so easy to seduce if you told them you love them without a carrot in your hand it seemed.
“See you tomorrow, darling.” you heard her calling out to you.
“God fucking dammit! You bitch! What does it take for you to hate me?!”
Rarity giggled in reaction. “Oh, darling. You are such a gentlemen.”
You dropped to your knees and began to scream to the heavens with your hands in the air.
