kai isn't stupid. he catches on pretty quick that there’s something going on between his dad and his older brother. the covert little glances, the way tyun’s smile never quite reaches his eyes whenever soobin touches him; it's all just little things but kai just can't help but feel like he's missing out. like there is a mile long chasm between him and his family, between him and tyun. what kai really didn't expect was for it to be well.. less than consensual. he catches them in the act one night, after waking up in the middle of the night to get a glass of water, noticing tyun’s door ajar, a bit unusual for his brother who is meticulous with his privacy. he peeks in, not at all expecting to see his brother ass up, face in the pillows, body trembling as their dad fucks into him. kai’s never seen him look this pretty before, with his hair damp and sticking to his forehead from exertion, making the cutest little noises. jealousy and lust both swirl in his gut and he sneaks back into his room jerkily. maybe he jerks off later that night to the idea of his dad fucking them both, envisioning how pretty his brother would look crying. he thinks of catching them in the act again, maybe recording his brother, since he wants to be such a slut.
