New Instincts

Wave One

The next morning when Y/N woke up she was feeling really shitty. Her hips, abdomen, and lady bits were so sore. She ached, when she moved it was far worse. At first, she thought she may be experiencing a period, but she hadn't had a period since becoming a hybrid.
Besides, this was far worse than any period she had experienced. She rolled over and attempted free herself from the tangled limbs surrounding her. She hadn't meant to whimper but moving really hurt. Before she knew what was happening she was being cradled in Jin's  arms.

"Shhhh...Bunny it's ok, I've got you."

"I think something is wrong with me. It hurts." She whined clinging to him for dear life. Jin rubbed her stomach with just the right amount of pressure in just the right spot. It wasn't an immediate cure but it certainly took the edge off.

Little did Y/N know Jin knew exactly what was wrong with her and so would others as soon as they woke up. The change in her scent made it undeniable.

"Bunny, sweetheart, you are going to be ok. Nothing is wrong with you. You are starting your first heat. To put it simply, all female hybrids go through this. It is as close to a human menstrual cycle as it can get. However, instead of it being monthly it will only happen every few months. It varies depending on the species of hybrid but it usually every 4 to 6 months. Unfortunately it can last up to a month in some cases. It comes in waves, and you just entered wave one. You will be crampy and sore for the first 3-4 days. You will also bleed too."

" Dang it! I thought I was done bleeding. Gross." She said pouting " what do the other waves entail?"

"Second wave is the shortest. For 2 days your body will heat up. You will be uncomfortably hot as though you have a fever. The third wave lasts anywhere between a week and 3 weeks. 3 weeks is rare and usually only occurs if the female in question doesn't have a partner." Jin paused for a moment trying to gauge her emotional status. He didn't want to scare her but he also wanted her to be prepared. She looked a little overwhelmed but otherwise fine he gave her hand a gentle squeeze before continuing his explanation. " The third wave also happens to be the most dangerous. During this period you may feel hazy and out of it. You will feel the desire to mate constantly. It will be uncomfortable, you will be frantic for relief. If for some reason your mates can't provide that relief, your instincts may demand you find another."

"No. You can't be serious Jinnie. I would never betray you guys like that!"

Jin gently rubbed her arms and whispered "Y/N it is ok. In a situation like that it is understandable, it would be something you would not able to control. That is why male mates are so protective of females during their heats, it makes you vulnerable sweetheart. You will be ok though you will be with Yoongi, Jimin and our alpha. You have nothing to worry about they would rather die than allow harm to come to you."

Jin tried to comfort you, but inside his own instincts were screaming at him not to go through with plan. Winter was coming which meant harsh conditions, and on top of that now they would have make sure you re-scented the clothes they were taking with them otherwise it would be clear who you were actually traveling with. Jin was worried but there was no way he was going to show it. Their plan would work it had to. "Will you be ok here, while I start breakfast?"

"Breakfast? Ah, yes of course, I will be fine."

"Good it shouldn't take long."

Not long after Jin walked away the others began stirring. Jimin made his way over to y/n and wrapped her up in a warm hug.

"Why do you smell so good y/n?" He stuck his face in her neck. How did your scent become so intoxicating overnight? A low growl startled him, he turned his head towards the sound and found Namjoon staring seemingly frozen.

"Fuck" He groaned "Now of all times!?" Jimin looked back down at y/n. She looked as though she was in pain, then realization crashed down on him like a train wreck. She's in heat.
