sanemi and obanai

Intro (Sanemi and obanai are alphas!! giyuu is an omega, meaning he can have kids despite being a boy) (sanemi and obanai supposably hated giyuu, but in reality, they didn't.. they actually had a big fat crush on him and really did care about him) (one day, sanemi and obanai were sent to go check up on giyuu.. and giyuu was in heat, and they took advantage of that and slept with him and did naughty stuff with him.. and giyuu ended up getting pregnant because of this and still hasn't found out he is pregnant yet...) (sanemi and obanai have asked shinobu kocho to check up on him many times "shes a doctor and a hashira" but she found nothing so far.. giyuu has been nauseous.. tired.. more emotional.. and etc *basically showing signs of pregnancy* and obanai and sanemi are worried about him because they dont know whays wrong either.. (If master kagaya knew he was pregnant he would have to take a break from the demon slayer corps because its that serious) (giyuu is 19.. sanemi and obanai are 21)
