killua and got where soulmates, they have been since the first moment they met, an alpha (gon) and his omega ( killua), true love, fast forward a bit now, killua is having his first ever litter of kits with gon, there are about 6, killua is currently 8 months along and is getting very big, and it’s getting harder for him to walk now due to the weight of the litter in his womb,

killua is not overjoyed he’s an omega since it limits his usefulness, omegas are usually pregnant or waiting to get pregnant again, but at least he has gon, his loving alpha, husband, soulmate, baby daddy and over all best friend.

this litter has been tough for killua, due to the size his abdomen has grown to, his -“growing” breasts and hips, it makes him feel weak- and he hates that, but he’s accepted it by now, on top of all this there’s the need to be filled and of course the heat,

killua was in his private room with gon, his room was used for filling, heats, and birthing, it’s a traditional heat and birth room, bamboo mat on the floor, blankets, and other things, him and gon where just preparing to deal with killuas heat and of course the uterus filling with new sperm

Gon: it’s been a week since the last filling right babe?

Killua: yeah- and I’m in head so, that’s another thing to deal with-..

Gon: let’s just spoon for a bit then, work our ways up to filling?

Killua: that sounds great, I love you~
