Well since this is no longer going any further I'm going to post the ideas I've save up bit by bit.
First idea is if the MC is invited to be in a porno that involves Salazzel who is a legendary porn star Pokémon (not an actual legendary).
Next idea is about the MC and the legends going to a Pokémon amusement park!
Bumper Cars: It involves the smaller legends (one at a time) except Mew. The MC takes the legend to have some fun on it and they site on his lap but they want to be extra secure so they put his dick in them without no one noticing. as the MC gets bumped around it makes her feel great until the MC is targeted by all and bumped from all sides making a big round "air bag" inflate which is the legends belly and making the legend love bumper cars.
Haunted House (being scared can be fun): involves Xerneas (pregnant). They go there to have some fun but she does not find any of it scarry at all and she was looking forward to being scared. At the end she goes on ahead and the MC hears a SCREAM OF PURE TERROR from her and sees her crying and scared of something and sees a FUN HOUSE MIRROR!????????. He sees his reflection is a bit thinner and then notices her reflection has a FLAT BELLY. She is scarred of that image but knows how to fix it.
Roller coaster: involves Rayquaza. There is a roller coaster that looks like her but she shows the MC she can do better than the fake.
Food eating competition: for any of the legends. Since the legends are so used to ingesting and being inflated so big regularly they can be considered pros. The food to eat are cream pies (the actual food) when the legend is done eating she still has room for some more cream (from the MC) to wash it down.
