Creep james x sirius x creep rjl x creep peter
james is disgustingly in love with sirius, he's been stealing clothes and items to jack off to since he discovered jacking off and now he's sixteen and the boy of his dreams comes running to him. sirius is in his house and they've been lowkey dating for a while now (neither of them will call it that, sirius because internalized homophobia, james because... Fear) and james has been so totally 100% chill about it. sirius is with him in his room in his bed and james is very very very possessive won't even let his parents talk to him for too long and doesn't even tell anyone sirius is there just keeps him inside the room. sirius is very happy with it - he doesn't want to talk to anyone, just wants james' company, and for now in his weakened state the possessiveness doesn't feel infantilizing (well, it does feel infantilizing but he doesn't hate it as much/thinks it's deserved) but comes off as james' love (which it is). peter finds out because james and him live close together and he comes over one day and effie mentions it to him. <- james seethes and screams and throws a fit about this btw. peter finds out and he's soo pissed because james should've told him ??? he's not jealous, so much, he's never wanted to deal with sirius' emotional baggage in long periods of time/knows sirius would never come to him anyway but he's also in love with sirius but in a diff way ? like he's doing the same things james does (looking at him in the shower, driving people away) but his is more stalker-y and james is more possess-y. james and peter fight and it's bad and bloody because they're both sportsy guys and they're both violent and they're both angry and want sirius. sirius is sooo out of it this is happening in the same room as he's in and they're strangling each other and he's just sitting there high as a kite trying to manually blink because his brain won't work anymore. he finds it weird but james basicallyyy gaslights him into thinking his doped up brain made it way bigger than it was and it was really just a little bit of shoving around for some totally unrelated reason to sirius. peter is pissed and 100% wants to correct him (he's the only one brave enough to admit that he's a total creep AND get off in it) but james will literally cut him up and set his insides on fire so he. refrains against it.
hogwarts starts and remus finds out and he's wallowinggg and he's so sad and cries about it for HOURS because of course the object of his affection was sleeping in another man's bed and he's so pathetic for thinking sirius would ever want to be with him and want him and love him and sirius is still disoriented and mentally ill -> constantly high so he's like huh i wonder what's wrong with him and james is 24/7 tailing him so he's like "idk baby let's go over there <33". remus is in love with sirius in a very wet cat way where he smells his sheets and jacks off into his pillow and sits in his bathwater and just overall cries a lot. he tries to romanticize it by writing in his journal but his handwriting is shit and it's so tear soaked it's impossible to read. remus tries to comfort him and get him things and weed and stuff to make sirius like him and sirius is like um ok james got me the good kind but thanks ig and yeah
eventuallyyy sirius catches on the three of them and he doesn't really change the behavior bcz he lowk finds it funny and he also really really needs everyone to love him now that he kind of doesn't have a family anymore. he goes to peter's games and twirls his hair and smiles all pretty and cheers super hard when he scores and gets high with remus and touches his hair sometimes and jamesss he's always with james, touches his bicep, kisses his cheek, wears his clothes. he leads them all on and they're aware of it (not james, he thinks he's the only one for sirius ummm ever) but they let it happen because sirius is paying attention to them too !!!
come valentines day and he wakes up to six hundred and two bouquets and also peter is dead and remus had a panic attack and is now passed out and james is just standing over there like baby hii i got rid of them <33 let's go on a date <33 and sirius is like ykw no fuck you then he goes to mary and mary's like um ok and then they date for a year and then mary kills sirius and then she gets sick from depression and before she can die from sickness she wants to kill herself and then before she can kill herself james wants to kill her but when james goes there and mary's begging for her life he just looks at her apartment and her manner and thinks how similar she is to sirius and then they both get really sad and make out and have hot disgusting sex and mary tells james she fucked sirius' mom and james starts crying and then mary gets icked out and then james' ego gets hurt and then he kills her and then he remembers sirius is dead and then he kills himself in the hopes that they reunite in heaven (they reunite in hell)
