Anal dilatation

I love to use my strap on with my male subs as well as with my female subs and so bring them progressively to enough anal dilatation of the anus or vagina to allow me then if I wish to bring them to other types of games like fist fucking or the insertion of diverse objects such as plugs of various sizes. I consider that the sub male or female must always be available, ready to be invested by his Mistress and so offer his most intimate orifice of his body to the pleasure of his Mistress.
