Could there be a side event where after a terrible storm the combee population is down a lot or for some other reason and Shaymin would notice it since they pollinate the flowers and plants to make seeds and she helps grow more flowers and would want the MC to help their population to recover before the regions flowers are effected. Shaymin would ask some combee to lead to Vespiquen (Queen) that remain. While making love to Vespiquen with each orgasm she has her breasts seem to get a little bigger till some golden yellow leaks out and this is how honey is made in the Pokémon world. After inflating Vespiquen her breasts are now massive and honey is coming out of her breasts like a fully open faucet and she lets him try some right from the source for the good time and his hard work. The reminder of the event can be he finds a jar of combee honey and remembers how honey really is made by them.
