Due to some trouble conceiving, Cadance casts a fertility spell on Shining Armor that increases semen production and libido. There's just one catch - it's impossible for the victim to cum until the spell is ended by the caster.

Contains: Orgasm denial, large swollen balls, large endowment, cum inflation, impregnation, and excessive cum/precum. Coverart by bakasan. A Patreon snippet written for dio-drogynous.
