Example, Alice(example) gets blackmailed by george(example) to get fucked by him in order to save Alex from something. But rather than just becoming another mother or rose, she gets dominated to the point of becoming georges slave in mind and body, she will be serving as alex's maid while her pussy is filled with george's semen, she will blush and tell Alex she has to use the restroom while they are in the city, while the truth of the matter is that she's going to go and service her true master's cock. She convinces herself that she's getting fucked for the sake of Alex on the surface, but happily squeals in delight whenever georges giant dick is put inside her. Uses excuses to get her masters cock whenever questioned, but happily avoids mention or thoughts of justification when ordered to present her pussy. Doesnt have to be alice of course, I would like it to be a situation where the girl tries to and believes she is hiding it from Alex, and tries to justify herself on the surface, but truly becomes a deprived slut willing to lie to her "love" all for the sake of getting her true masters dick in her pussy for a moment longer.
