I knew my heat was starting today but it made me sad as I won't get to spend my birthday with my family which is mum and Kacchan. Well it happens a few times, some years I get to spend it with them if my heat has been late or I've taken my suppressants "Alpha" I call walking into the castle "Alpha" I yell "What?" he asked sluggishly with a few cuts on his cheek "Who did this?" I asked cupping his face "I was training with Bakugo not long before you came" I growl at this "Woah, take a step back" I went to step back.

He gripped my hips before I could "Metaphorical not literally, why are you here?" I smirk and nudge him back until his back was against the wall of the sitting room. "Oh I don't know alpha possible my heat and your rut start today but I guess you aren't feeling it so I'll leave" I gasp as he growled in my ear burying his noes in my neck "Alpha" I called as he nuzzled my neck. 

He hummed inhaling "I was wondering why I was more aggressive recently, especial when I was training with Bakugo now I know." he chuckled "I guess it never clicked as you are always here a day early so I didn't really think about it." I hummed listing to his voice deepen "My rut naturally gets heightened when I have sniffed your scent. Oh there it is" he mumbled inhaling my scent deeper.

He growled in my ear "Sorry I didn't come early my mum wanted me to spend a day with her so we can celebrate my birthday as I'll be here when it happens." he purred at hearing this "My room now, build our heat nest and get rid of that other temporary one, it keeps falling apart and I haven't slept well" I giggle as he let me go, that's the thing with alphas once they have slept in an omegas nest they can't sleep without one.

This means most omega get made to create a quick makeshift one using the whole bed but for the ones like me who have a good alpha who askes we tend to build one anyway and make it more properly spending more time on it. However I always make a quick heat nest, which tends to be all half the bed as it keeps both people close together but also allows enough room for activities. 

As Shoto's bed is so big our nest looks tiny but compared to most omegas nests my one is probably double the size, even so Shoto manages to be flush against me the whole time which I love. I sighed shaking my head at the completely fallen apart nest, can't be helped he has spent these past three weeks in it. It was the one I had to remake because of the activities after the beach with me helping him get off, which left it in a bit of a mess. 

I threw everything off his bed except the undercover. I used the blanket as a bundle base then began using the clothes to create walls "Shoto grab me the stuff from the cupboard" he did as I asked "Thank you, if you will try coping me on the other side please" he nodded and carefully began trying to copy me, it was cute. He was so close to being right "Here look like this" I grabbed his hands going behind him then guided his hands "There now you got it" he smiled doing it perfectly this time. 

I went back to my half. Once we met at the side I took over weaving the sides together. "Now pillows" I grabbed his pillow inhaling his scent with my face pressed into it "Perfect omega" he said rubbing my head "Alpha" I purred leaning into it more. "Finish our nest then we can snuggle" he whispered in my hair. "Okay alpha" I happily and quickly finished off our nest "Done" I said facing him seeing him in only boxers "Strip" I squealed doing so quickly until I was in only my thong which said owned on them. 

Shoto licked his thangs and I smiled gasping as he pinned me instantly down in our nest quickly "Mmm" I moan as he connected our lips quickly "Good boy" he whispered in my ear "Good bunny" I whimper "Please alpha please" I whined hocking my legs on his hips "Wait omega I'll fuck you when I'm ready to" I pouted whining "Why wait?" I whisper in his ear "When I'm so wet" I nibbled it gently "And so ready for alpha's cock and knot" I said nibbling and licking down his neck.
