You let out a sigh as you realize that there's no avoiding it and allow yourself to relax and submit to Duke's actions. "Good Bitch," Duke says, "Since you gave in, I'll be gentle," and he slowly begins to penetrate into you, the juices of his dog-cock acting as a natural lube.
You gasp and tense up a bit at the sensation of being penetrated as a male, but quickly remember to relax so that it doesn't become pain. You try to place the feeling as Duke continues to slide into you, it doesn't really hurt, but it isn't really pleasure either. It's more like a gentle massage, oiled skin on oiled skin, combined with the feeling of a stretching exercise. What you do know is that it is definitely arousing, and you soon have a boner as Duke enters you fully and then begins slow thrusts, in and out, in and out, "This isn't so bad," you think as a sensual fog begins to cover your mind, "I kind of like it...wait...no!"
Your eyes widen with fear as realization penetrates the cover of relaxation, you're ENJOYING THIS! "That's not right! I-I shouldn't like this! I should be repulsed! disgusted! outraged!Submissive...obedient...thankful to my handsome Master for making me feel so good. No, No I've got to fight this!"
"Do you?" the Bitch asks, "Doesn't it feel good to be this way? To be submissive?"
"N-No..." you lie.
"Doesn't it feel good to know that you please the one who gives you this feeling? Your Master?"
You glance back at Duke on top of you, dominate, virile, humping away at your ass, "...n...n...no..." you desperately try to lie to both the Bitch...and yourself.
"Stop fooling yourself. You like belonging to someone. You like being a toy and a servant. You like being a horny, slutty little Bitch in heat, ass high in the air with your Master's rod slamming into you again and again! You think of nothing but pleasing him and your dreams are all of him banging you like the Bitch that you are! Admit it, to me, to him, to yourself and the whole world! You love it all! Don't you?!"
Duke's cock rubs up against something inside you, amplifying the pleasant feeling a hundred times and turning it into full sexual pleasure! "YEEEEEES!" you cry out, "YES I DO!"
"Bingo..." Duke whispers as he begins directing his thrusts toward's that spot. You're mind is drowning in a flood of pleasure and you see the collar hovering in front of you. It splits in two copies, one floating back to its original position but the other staying in front of you. As you watch the copy's runes disappear and the leather slowly turns pink and a gold, heart shaped tag appears on it. It winds itself around your neck and fastens itself magically. Not to tight but snugly. Duke then knots inside your ass, spreading you as wide as you can go and firmly planting his dick in your sweet spot! "TAKE MY SEED BITCH!"
"YES MASTER!" you yell as his cum gushes into your ass, filling it up, and the sudden warmth and wetness inside you immediately makes you cum as well. And the tag on your new collar takes on an engraving:
Duchess
Duke's Bitch
