It began with a stupid wish...

Starlight is tasked with 'testing' a magical wish stone by her former teacher Twilight Sparkle. Feeling naughty, Starlight invites Twilight's new student, Evening Storm, a shy, but good-natured unicorn stallion to aide her in some experiments. Evening just didn't know it would lead to a stallion turned into a copy of Starlight in a sexy outfit, and him being made to play the part of this new mare's husband!

It's okay though. There is a catch. The moment either Evening, or the Starlight Twin is made to cross a line they don't want to cross (Kissing, touching, etc) the spell will end and they'll be free! No way this goes on for long right!

Right?

Little does Evening know that this is just the beginning of a harem. A harem filled with pregnant wives! Many who used to be stallions!
