Gather round, children! It's story time!
[spoiler]So, elsewhere, I'm in a small SU RP with a very small group of people. You can count the amount of players on one hand. It's that small. We each have multiple Gemsonas of varying ages, but most are over 1000 years old. 1000 years old is the Gem equivalent for 18 in this particular canon.
One player (Bugles) has a Peridot (Pistachio), who was made after my Peridot (Mint Chocolate Chip). Pistachio decided to just join the group with another player's (Fritos) Tourmaline (Rocky Road), Pearl (Butter Pecan), my Garnet (Neapolitan), and my Pearl (Peanut Butter). Along for the ride is Pistachio's human friend, Twinkie.
Bugles found out about Mint's past in some OOC discussion and they decided that Pistachio should have a similar one. So, they brought in the FBI to capture Pistachio. Fritos and I said no because of the location of the Gems' hideout and the fact that no one knows about them. At all. So, that was stricken from canon.
Meanwhile, Mint and Rocky had formed a relationship and Bugles wanted Pistachio to be shipped with Rocky. Rocky is a flirt and would flirt with Pistachio and that was fine. Then, Bugles revealed Pistachio to be about 150 years old, which in Gem terms is very young. Pistachio is a minor. Rocky stopped flirting with her immediately and the other Gems won't touch her.
Pistachio tried to force a ship with Mint, but Mint isn't interested. Also, the age issue. Pistachio was also very annoying and bothered Peanut Butter for her e-cig and would even try to smoke cigarette butts. So, Peanut Butter doesn't like her. Butter Pecan doesn't like Pistachio because she's annoying. Neapolitan is indifferent to her and they haven't interacted much. And Rocky ain't touching her.
Bugles gets frustrated and age-advances Twinkie so that he's now 18. Twinkie and Pistachio run off together and Pistachio is sexually assaulted by a biker gang. Again, this is partially co-opted from Mint, who was kidnapped long before she joined the other Gems. Pistachio is rescued and Mint tries to comfort her and again, Bugles tries to force a ship with Mint. Mint isn't interested in Pistachio because, again, SHE IS TOO YOUNG. Bugles doesn't get it and draws smut of Pistachio and Mint.
Because Pistachio isn't getting laid, Bugles draws smut of Pistachio and Twinkie. And then he has Pistachio try to [twin slasher] Twinkie. Twinkie poofs her and she's bubbled. Bugles wants her unbubbled but refuses to change her character. He keeps trying to force a ship with Rocky because he wants Pistachio to smut with her, and accuses Rocky of not loving her, and then blames Fritos because Pistachio is too young and we want nothing to do with that creepy pedo ship.
Eventually, Pistachio escapes her bubble and runs off. None of the other Gems can give any less of a chicken-fried [tornado fang]. Bugles yells at Fritos and I for not accepting the ship and "forcing" the age restriction and he can't seem to understand just why we think it's gross. We even tried using two other off-limits Gems as examples. My other Pearl (Wild Cherry) and my cluster (Superchunk) are off-limits. Wild Cherry isn't even a year old. She is a BABY. She's not allowed to be shipped because it's gross and creepy and takes advantage of her naivete. Superchunk is a cluster. It has no lower body. It's off-limits because it's basically a pet.
Bugles still didn't get it. He threw a fit and left after we told him that we're fed up with him forcing this weird and creepy pedophilia ship when he has other Gems who are of consenting age.[/spoiler]
TL;DR: If your character is a teenager or younger, don't force a smut ship with an adult character.
