She embraces Selena, taking things a step further

As Selena held Mommy, she felt warm, impossibly warm, so warm that Selena took a minute before she realised it wasn't simply warmth, it was a weird sense of genuine kinship with Mommy, as if she had always been Selena's mommy, looking up with teary eyes as Mommy asked what was wrong, smiling, giggling, blushing, and assessing Selena for any scrapes of bumps, showing a level of coddling that Selena's mom had never shown her.

It would be a heartfelt moment if Selena didn't suddenly feel her dick rising, pressing vigorously against Mommy's stomach and thigh as it rose, soon met with Mommy's soft hands as she rubbed the big head of Selena's huge cock.

"Someone woke up in a good mood~" said Mommy

Selena was confused by this situation, but then she peered back into the System Window, assessing what she had done to make Mommy act this way. Then Selena face-palmed as she reread the features she added in. "A mindset of accepting her daughter in any situation, wanting to devote herself to her daughter, and being filled with endless love for her daughter. As well as an unchained libido that could save Selena from her mother's scorn, should the acceptance and love for futa not be enough to bridge the gap between mother and daughter." Unexpectedly, Selena had made it so Mommy was accidentally attracted and in love with Selena, not just loving Selena. Other features supported this, so when Selena then went to read the added in history data from the final confirmation option before spawning Mommy, Selena learned that Mommy had always been attracted to Selena. It was love at first sight to Mommy, who birthed Selena and, upon seeing her for the first time, although she was overjoyed and happy to have her child in her arms, was awe-struck, as if the two were Romeo and Juliet, star-crossed lovers intertwined at a gaze.

For years, Mommy had tried to get closer to her daughter, ensuring she did everything motherly with the intent of showing Selena the love of a mother, but also that she did everything in her power to try and get Selena to love Mommy as a woman, not just as a parent. However, her efforts seemed fruitless for the most part, but in the later years, Selena was beginning to feel turned on by Mommy, and when Mommy doubled down by doing stuff like pressing her divine ass against Selena's boner as they watched TV, Mommy knew that she was breaking down Selena's walls.

But now that all seemed inconsequential, because although Mommy was planning for Selena's libido to topple over and make her pounce on Mommy, Selena was now acting like she didn't have any of that prior experience, and simply couldn't stop herself from revealing her attraction to Mommy.

In this way, Selena was given a choice, to pull back and start/continue a life of playful seduction, or take Mommy here and now.
