Foot gagging is a practice linked to foot fetishism.

Under constraint, the submissive is forced to welcome deep in his throat the divine foot of his Mistress.
Exceeding himself, he gradually feels the pressure inflicted by his queen, the toes caressing his throat, depriving him of this vital need to breathe.

Choking, some tears of pleasure flow on his cheeks.

Struggling to satisfy his queen, the slave of her feet abandons himself in pain to the torture imposed on him, opening wider, until he is once again allowed to catch his breath.
