Original Description:
 
Special Forces operator Sunset Shimmer captured an enemy soldier, a Lieutenant by the name of Night Glider. The first round of interrogation went as expected: Night Glider stonewalled, so Sunset brought out the feeding tube. A force-feeding session or two was enough to make nearly anypony crack, but somehow Night Glider was far more resilient. Stranger still, as Sunset shoved more and more food into Night Glider’s unwilling mouth, those calories were somehow all accumulating on just one region of her body. Admiring the view, Sunset Shimmer realized that testing this pegasus’s resistance was going to be even more fun than she expected.
 

 
A commission from Bakki on DA. Super happy with how it turned out.
