This is a reader insert, drabble request from an anonymous where Reid finds out you and Morgan are dating and you're Reid's sister, it's over 100 words but I hope you like and please review
Reid stood staring at you and Morgan holding hands completely in shock, yet somewhat angry and confused
"So you two are like...together together?" he asked looking at your intertwined hands
"Yeah and we're happy and you've known Derek for a long time and he's a good guy and...Spence you don't look so good," you say observing your brother's pale expression
"Oh oh no I'm just...confused,"
"By?" Morgan asked raising his eyebrows suggestively
"How Derek Morgan, the guy who'll screw anything with a vagina-"
"Spence!"
"Alright alright I'm sorry Y/N," he chuckled "Just don't hurt her...I may look weak and scrawny but you know I can pack a punch especially when it comes to my sister,"
"Alright I gotcha Reid, now if you're done lecturing us we're gettin' late for a date," Morgan said walking off with you
Also I shall be updating my stories when I return from Paris in six days
