Yes it is!

You wake up on a beach, you look around and see some rocks, after a moment, you notice a building with a glass front, which you immediately know is the Big Donut. Someone comes up to you and helps you up. You recognize the blonde short stack, "Are you okay? You just kinda fell from the sky." Sadie says, "Yeah, we are fine" your sister also woke up just a few seconds after you, "This is a beach city, right?", "It is, is you guys friends with Steven or the gems by chance?", "Sort of. We may need to go speak with them soon." A transparent being appears behind Sadie and moves into her. Sadie stops moving for a second before her eyes change color and seems to be a different person completely. "Sorry I had to take over this form, I needed a way to speak with you, you were supposed to be at the top of the lighthouse, but that didn't... end up... happening,", The goddess, you assume, starts playing with Sadie's body as she tries to speak. and gets distracted with her tits. "Um, who are you?" you tell her. She snaps out of it for now, "Ah yes! I am the Goddess of gems and crystals. I created the gems of this universe. Although the god of time made the original one before I got here, he created most of them after all. Either way, I need you to breed the humans of this land, as well as the gems, to make sure they do not go extinct. It would suck if they did. I want you to breed this body first. I love it too much" She started playing with Sadie's tits again and rubbing her crotch but did not get distracted this time. "I would prefer if I got to breed Sadie herself, not just the body.", "I understand. That may take a while, but I will stay inside her for now, and I will feel anything she does once you get to her. Sadie will not remember any of this and will continue like normal. After you finish talking to her, speak with garnet, one of the few gems to understand what is going on. She will use her powers to help you breed the other girls and maybe let you breed her as well. However, you may have to breed her separately.". Sadie's eyes change color again, and she turns to normal. "Well, either way, I hope you guys enjoy your time here. I know it isn't a big place.". She walks off waving, and you and Grana wave back. Grana was confused by that event, but you both head over to the temple, ready to speak with garnet.
