Summary
As Regulus' first heat slowly approaches, Sirius gets more and more worried. James promises to help Sirius protect his brother, but what happens when James is the one to find Regulus in full-blown heat? And why does James start feeling strange tugs at his heart, a fluttering in his stomach, whenever he even thinks about Regulus?
Note
YALL I'VE NEVER RLLY SHIPPED JEGULUS BEFORE BUT A FEW WEEKS AGO I READ A FIC AND SUDDENLY I FELL DOWN THE RABBIT HOLE AND I CAN'T GET OUT (i don't ever want to get out). so... yeah, now i'm the biggest Jegulus shipper so ofc i had to write an omegaverse fanfic lol. i had planned on only writing a oneshot but then i just kept writing, the word count kept growing, so it left me with no other option and now there's gonna be multiple chapters. enjoy?
