Keep going, but then consider

Jaune continued ramming into Ria. He could feed his original cock begin to twitch. But he held out, wanting everything to happen at once.

But he could only hold out so long. As he watched Glynda orgasm, he sprayed his load into Ria's ass.

His second dick retracted, but he continued pumping into Ria ad Glynda stumbled back into a chair.

Finally, he exploded into Ria, as the two orgasmed together.

All three of them took a breather. But as they did, Jaune began to consider.

He could give himself a second dick. He had used the note before to change some biological things as well. Yang, Blake and Velvet now changed to have more animalistic features when triggered. He could enhance triggers with changes too.

For example, Nora could have a bust size "dial", or Glynda's slave personality could give her an even more shapely body. Making someone act like a bimbo could make their hair blonde and inflate their bust. It was something to think about, at least.
