~I went twincest. Hope that’s okay~
It was manageable when he was younger, and people said it would go away eventually. The habit of sucking his thumb was damn near impossible to break. Then the combination of gum and lollipops that got him through elementary school; it didn’t help that his older brother Gabriel could always be relied on to have a spare sucker tucked away somewhere.
As his high school years rolled around, the problem suddenly seemed to stop. His parents were relieved, as was Gabriel, and everything appeared perfectly normal. Of course, if you were to open the twins’ door at any given time of day, you’d realize that Cas hadn’t actually gotten over his fixation, he’d just found a new outlet.
He liked the feel of Jimmy’s lip caught between his own and the feel of his twin’s tongue hot in his mouth. He liked the way the skin turned red where he sucked, and he liked the little hiss Jimmy made when he bit down a little too hard.
But his newfound favorite thing to have in his mouth was Jimmy’s cock. Long, silky smooth, uncut and gorgeous, it lay hard and heavy in his mouth. He liked the weight on his tongue, he liked the tight press against the back of his throat, he liked the heat and the size and the way it stretched his jaw and made his lips wet with excess saliva. He liked to curl his tongue and explore, he liked to suck and work his throat, he liked to hollow out his cheeks to feel as much as possible. He liked the taste of his brother’s come, he liked the feel of it sliding over his tongue, and he liked the way Jimmy’s fingers would grip his hair as he tried to shove in further. He liked it all so much that he would just keep sucking, running his tongue around Jimmy’s softening cock, and Jimmy would have to yank his head back when the oversensitivity was too much.
~hope this is okay? It’s kinda short and unedited but… yeah?~
