Shoto pov:

I Purr as my omega pampered my chest and neck in kisses, we have been in heat and rut for two days now and he's been pretty calm "Alpha, I want a mate mark please" he asked sitting on my abdomen. We were in our nest in my room both naked "Omega not yet" he whimpered "Why? why not alpha?" I rub his lower back "Because my sweet omega, we have to wait just a little longer before we can mate, you need to be 17 as well my love" he whined pawing at my chest.

He released more of his scent "Alpha please, please just mark me. I don't mind waiting to be mated and knotted but please mark me." I cup his cheeks "Please it hurts, need you. Please alpha please. I don't care if the mark disappears later just mark me and make the pain and heat stop" I bit my lip trying to fight my alpha taking over. He knew our omega was in pain and begging us for a mark.

Izuku whimpered "Please" he said nosing at my neck "Why don't you take heat pills?" he pouted rolling off of me "Because they make me feel shit" I sigh then hug him from behind "But isn't that little tummy ace better then this pain" he shrugged "If I start taking them then I don't get to spend this time with my alpha" I kiss his neck then look at his unmarked gland "If I mark you and it disappears you know that would mean we aren't fated?" he nodded looking over his shoulder.

He smiled shrugging "But I don't care because you have always been the one I want. Me, my omega and vampire want no one but you, you're alpha and vampire." he confessed "I'm yours Shoto, my heart and soul and even body though technically...hmmp" I kiss his lips softly "You do know that if it stays we are fated and are in a lot of trouble for marking before my father has got to announce my courting to you" he nodded giggling.

His giggling stopped and only a smile remained on his lips "Yeah but I can just wear collars to formal events or say that because we are fated our second genders kicked in and marked each other afraid of losing one another" I hummed and smile at him "Mark each other?" he blushed then turned away "Y-yeah only if you want to, or if you want my mark. I knew most alphaaa" I nibbled his ear.

I chuckled at his reaction "I never said I didn't want your mark. I would love it" I noes at his neck "Are you sure because if this stays it's going to be hard being apart and hard to restrain from some form of contact until we mate" he nodded "Yes Shoto, please" I kiss the gland and he gasped "Please" I hum and began sucking on it gently flicking my tongue over it earing a moan out of my omega. "Ready, it'll sting" he nodded and I bite down into it allowing my alpha to place the mark. 

Which is just me pumping some of my vampire venom in him. "Ahhh, mmhhhmm" he gasped and moaned gripping my hair granting me more access. I pull off then licked the blood "Alpha" he panted then moaned as I began sucking on the holes drinking the blood. I wrap my arms around his waist holding him against me tightly as I drank. I pull away and heal it kissing over the mate mark. 

I purr seeing it glow a sigh my omega wants to mark me and or feed. The more it glows the higher the need for blood. I smiled as he flipped over "Go ahead omega mark me as your alpha" He latched onto my neck his thangs sinking deep into my unmarked gland. I felt the sting of his venom then the pure bliss form being marked. I close my eyes seeing flashes of his childhood, memories I wish he never had but glad he was allowing me to know. 

In a marking phase, one can pick and chose how much their mate can see, I allowed him to see all of mine except maybe some ruts where I got myself off to images him. He had begun drinking but I was still getting memories, he was truly sharing it all with me. I gasp as my vision came back to see him looking into my eyes "I know a lot huh?" he said with a sad smile.
