Shining Armor and his wife Cadance were presented with wonderful news earlier that year: After some discussion, it seems that Night Light and Twilight Velvet want to try and have another foal! The younger couple were absolutely elated, and didn't hesitate promising to help however they could. However, neither of them expected for their parents to ask an unorthodox request from the two.

Since Velvet is too old to get pregnant again, and neither her or Night wanted to try artificial insemination, that meant they had to find a mare to be their surrogate the Natural way...

And since Cadance is literally the Princess of Love, she wasn't against volunteering with her husband to help~

Note: This story was written for the Father's Day '24 Contest happening in the Incest is Wincest group. That should give you a good idea of what to expect, including Incest (Duh~), M/M and M/F action, cuckolding, chastity, throat-play, and other lewd happenings between a married couple and their In-Law~
