Blackmail, Blood Royal, Bondage Game, Depravity, Family of Debauchery, Living Sex Toy Delivery, Night Shift Nurses, Sibling Secret, Teacher's Pet, Shusaku...the majority of hentai has bdsm.Originally Posted by Roof
DearS is a recent anime that has subtle ds themes (actually, it's pretty apparent for those into bdsm) as well as Ikkitousen which is much more subtle.
While I am on the subject, for those into hentai, NSN is a must if you haven't gotten there yet (what have you been watching?) and for those not, still check it out...there's some great ideas.
