Had a possible idea for the egg laying at the end of the chapter with Kyogre, Groudon and Rayquaza. It could be Kyogre is on left, Groudon on right and Rayquaza in the middle between the two since if the two were side by side they would fight. The two would be arguing who gives birth first so the MC decides to do both at same time (maybe with some help from Palkia space bending to reach both at same time) while he is inside them his face can be right in front of Rayquaza pussy so he decides to make her feel good for keeping the two under control even now with his tounge and face. Rayquaza has a few orgasms and the MC feels something hard in front of his face and its her eggs but still need him to reach in to pull out. Both Kyogre and Groudon both accept that Rayquaza got first (since always been beaten by her) but now argue who is second. The MC would find both their eggs at same time and pull them out at same time and even after the eggs come out on their own would be at same time. The two would be tied for second but then argue whos eggs will hatch first.
