Fucked first , then filled with cum as the doggy dildo expands the knot. If with a real Dom , he could REALLY inflate that knot and leave me tied on that cock - sissybloke
Sissy must use the dildo when the cock is in chastity, don't like to use the dildo but must try before the cock is unlocked. To stretch the asshole, he used a butt plug that he liked a lot. - cd_Jennifer85
