Dark Glare and Shimmering Glow feeling their quintuplet siblings kicking in their mother’s tummy.
 
Story:  
Dark Glare and Shimmering Glow desperately wanted another sibling and they quarreled whether a brother or a sister would be better for them. Not wanting to turn down their children’s wishes Sombra and Radiant agreed to have another sibling for them but they couldn’t guarantee the eventual sexes of their siblings respectively. After a few nights of trying Radiant got pregnant successfully and surprisingly they got more than they wished for because Radiant happened to be conceived with quints naturally, which comprised of twin colts and triplet fillies together. Despite their mother having more girls in her womb both Dark and Shimmering were satisfied at last
 
(I think this would be the first ever pregnant Radiant Hope pic ever existed)
