Poly-ish Metcest, but jealous and toxic. Ryan and Adam fighting over Jack because they’re so possessive of their youngest brother.
And Jack LOVES it. He thrives off the attention, being the baby, being desired and protected. He feels guilty watching them argue and threaten each other, of course, and he knows there’s a rift between them because of it. But it’s addictive, and he can’t get enough of how extra sweet and attentive they are with him when they finally have him alone.
It’s like the only way for Adam and Ryan to come down off the stress of fighting with each other is to lavish Jack with attention, and each are trying to convince him they’re the best for him, hoping he’ll choose them in the end. They all live apart, Jack stays the night with one or the other on most nights, so they get to have him all alone, but never for very long.
Ryan knows how much Jack craves physical touch and affirmation, so he is constantly kissing and cuddling him, giving him massages, complimenting all the little things Jack does that only he notices. He reads Jack so well from being close with him and writing with him all these years, and he uses it to his advantage as much as possible.
Adam is more physically and verbally reserved, but just as desperate, and ever the romantic, so he’s learning to make Jack’s favorite dishes at home. He is listening to Jack patiently, offering to help him with anything at the drop of a hat, even if it interferes with his busy schedule. Jack is his top priority, and Adam loses sleep over him any night he’s not in his arms.
Ryan is fucking him immediately, from the moment the relationship starts, and Jack is super eager. They’re always giggling and grabbing and tickling each other. It feels so natural. Jack loves it, loves how enthusiastic and adventurous yet gentle Ryan is with him.
Adam takes forever to even broach the subject of sex, but when he does, and Jack agrees, he fucks Jack like he owns him. Not always rough, but always dominant. Giving, but in a calculated way. He wants to keep Jack compliant and submissive and begging for more, so he’ll never leave. Jack finds himself so deep in a submissive headspace when he’s with Adam.
When Adam finds Ryan’s hickey’s on Jack’s neck, his jealousy flares up and he covers him in his own bites- all over Jack’s neck and chest and thighs.
Every time Jack studies the marks across his body, counting them, comparing the way Ryan’s and Adam’s look (Ryan’s are lighter, mostly from sucking, and Adam’s are darker, all teeth), he gets so turned on that he has to jerk off.
