It's been years since Spike and Flurry had began to date under Twilight and Cadance's noses, sneaking make-out sessions here, quickies there, even blowing the young dragon beneath the table at family dinners. Spike enjoys his time with the beautiful princess but he doesn't want to hide their love forever. So, during a visit to the castle, Spike hatches a plan that will not only bring their relationship into the light of day, but also make a good gift for their mothers this coming Mother's Day.
Flurry likes it.
Spike likes it.
And they're sure they can make their moms like it too.

This fic is an idea that came to me, where else, in my sleep. It will have the following:
F/F, M/F, cunnilingus, blowjob, double penetration, rough sex, grown-up Spike and Flurry Heart, incest orgy, foodplay, cum, anal, etc. the list could go on forever if I let it.
