Here is Cadance enjoying the usual taste of sending her unicorn husband down her throat. This happens to him sometimes from any stupid thing he does where he gets a chance to be that much closer to his wife from within and Cadance is very aware of this. If he does anything stupid around his sister Twilight like knocking over her books or saying things like 1+1=3, she'll make him massage her feet, use him for strange harmless experiments or swallow him as well. Yes…he'll sometimes do that on purpose to his sister as well just for her to dominate him. Cadance purposefully puts on just a small custom bra strap that Shining loves seeing before they proceed with sexual shenanigans in bed, but he can't this time due to his punishment. He must now suffer not seeing her wear it.
This was all inspired by a series of stupid and silly things Shining does that puts himself in bad situations as well as others sometimes that artist have drawn over the years and they're hilarious. The "Shining Armor is a moron" tag. I love seeing how Cadance is usually drawn as the one that's far more intelligent and dominating over her unicorn spouse where artist will put him in some funny situations. By far the funniest one I've seen was where Shining tried to trick Chrysalis into drinking a paralysis cup and he ended up tricking himself and drank it instead after she pointed out that she drank from the normal cup.
