Master uses his new slut

You watch as Master walks up to Juho, who looks timidly up at him with a worried, but submissive gaze. She really looks just like you, and it makes you wet just watching her and Master, with him clearly preparing to use her, her petite frame lending well to her obvious submissiveness, the same submissiveness you have towards him.

"Juho, your sister already did her work for today, now it's your turn. Service me like a good maid should", he tells her, and she nods slowly, getting closer herself and opening his pants to reveal that magnificent cock that makes your mouth water, and makes you feel jealous of Juho, regardless of how humiliating it is that you used to be Mark. Mark is gone forever now, and you should embrace being Mariko, including loving Master's cock.

Timidly and slowly, Juho opened her mouth and started to give Master the blowjob he requested, though she is slow and seems a bit inexperienced. Master looks at you and nods, and you understand his orders perfectly, quickly making your way behind your sister and placing your hand on the back of her head. Then, you push, helping her move faster and with more confidence, and giving more pleasure to Master, just as he wanted you to.

Juho weakly attempts to fight back against your pushing, but a quick spank makes her stop acting out, instead submitting to both you and Master. You feels as though you just established some sort of hierarchy, with Master at the top and Juho at the bottom, obeying both you and Master. You like the feeling of having a bit of control over something, while still being Master's devoted and powerless slut.

And you especially love the feeling of Juho's timid squirming, doing her best to obey Master's orders and your pushing her forwards to do it better, coaxing her into taking more and more of Master's dick in her mouth. With your skillful pushing, it's not long before Master cums, filling Juho's mouth with him delicious liquid.

"Swallow it all to show me how much of a good girl you are, Juho", he orders her in that heart-stopping commanding voice of his, and she quickly obeys, all of it going down er throat as you feel a tinge of jealousy that you didn't get any, but together with massive amounts of shame and humiliation at the fact you had that thought.

"How did it feel, Mariko? Watching your former girlfriend turned twin sucking me off and swallowing my cum while you helped her?", Master asks, looking down at you, and you blush, unable to be anything but honest with him.

"It made me feel really hot and bothered, Master! But also jealous I didn't get any cum...", you tell him, shame readily filling your mind as he laughs, his dick not too far from your face as you feel your mouth start to water again.

"Honestly I never expected that response, but it's good. Keep being a good girl and **** and I might give you a reward", he says, laughing again before leaving, gun in hand. You can't help but wonder what will come next.
