Whipping a slave's tits
This pic displays almost perfectly the most effective way to whip a submissive's tits. A sting lash delivered across her tit, flicking her nipple and curling round into the sensitive area under her arm. Of course it hurts but it also wildly increases the blood supply to the breast and, in my case at least, makes my nipples stand out like door knobs. If your slave has decent sized tits they will wobble and quiver deliciously too.
