Graciuos man, this is unique! What a sub you 've got. Don't worry if it fits BDSM or not - you and your lady are into something different and way out. The last picture may be a bit out of focus but I'd love to drag her well-fucked, drained, dripping body out of the water with a couple of friends and force her into a rape-style workout. Those nipples look just ready for chewing as does her thatch.
Imagine what it would be like for her to be lying on those boards, her legs held spread open having to accept impregnation by another group of horny men just after finishing another group session. Awsome. Could she last the pace? Might just get rid of her come hither look though.
