She took over and punished Rio

Knowing her entire existence was a lie, Domina wanted to lash out against Rio and sink into a shell of ambiguity. But she couldn't deny that Rio genuinely loved her and expected nothing more from her. Considering how he treated others and normal relationships, she knew he treated her like she was a real person, but that still didn't give Rio the right to make everything she knew a lie. Knowing about the Family Maker and its traits, she knew that he could have created her with a neutral opinion and built a relationship, or just use the treasure as intended and make a new family without any background and a bit of incestuous love. However, Rio didn't do that, so after some deliberation while Adolpha comforted her, sensing that Rio had done something wrong, Domina eventually took one last look at Rio's pleading face as she decided what to do.

Instead of just bringing everything done, she made it clear that Rio was on thin ice and that she wouldn't let him do what he had just done, at least not without supervision, deciding that she'd trust her feelings just this once. So, seeing how Adolpha's fresh pussy was already turning to her, she made Rio feel her hurt by taking Adolpha for herself. Bringing Adolpha's face closer, she became like a submissive puppy to Domina, quivering when Domina's tongue entered her mouth before licking her face, leaving Adolpha stunned as Domina quickly picked her up and started fucking her, telling her to show Rio some love, causing the Domina-obsessed Adolpha to give Rio a semi-lazy footjob, finally giving him some love when Domina threw him onto the bed so he could get a titjob from Adolpha as Domina rode her from atop, leaving Rio squashed and quickly covered in Adolpha's girl cum and sweat.

After they had this long sex marathon, the three of them watched a movie on the couch. Domina held Adolpha close to her as her arm reached over Adolpha's other shoulder, leaving her to put her hands in her lap as she blushed, acting like an embarrassed schoolgirl out with her crush, both of them forgetting Rio was stuck between them like a child for a second.
