I will add one instrument that brought me almost to tears the other day. I was being spanked very hard when my spanker had me turn over and put my feet in the air in classic diaper position. He made me hug each thigh thus spreading the legs. He pushed the legs back even more and held them straight with his left arm while he caned me right in the crease between the thigh and butt. He did this long enough to get the amount of bruising he wanted, which will cause me to have problems sitting standing and walking.
When he finished his caning procedure he picked up a bath brush, this small spanking surface implement fit perfectly in my "taint" the area between the scrotum and the butt hole. I have been spanked in this position with this instrument many time, but he took me to a whole new level. The strokes were hard from the beginning, he did not stop at ten as is his custom to give me a bit of a break and rub the affected area, he continued for about ten more strokes the gave me a few seconds respite. I though he may be finished with that part but he pick the brush up and started, again. By then I was almost crying, something I have never done during a spanking, I was twisting and trying to avoid this horrible thrashing when gave me three quick moderately hard taps to the balls and told me to hold still. You can certainly believe I did as told. I thought he would never stop but eventually he saw some drainage from my penis and stopped. He gave a very gentile massage to my injured area and massaged the balls very thoroughly. By then I was hard as a nineteen cent chisel and about three strokes brought the expected results. God I was glad that was over, not the orgasm but the beating. I thing that was one of my greatest orgasms.
He did not put my legs down immediately, this position was very uncomfortable and I wanted down.
He picked that bath brush up and gave me twenty more hard licks with it. I screamed after about three but that did not deter him, he paddled a way without seeming to notice my pleading and other vocalization.
He let me down, threw a towel on me, had me clean up, then stood me up, had me put my thin shorts he requires me to wear, turned me to face his left then laid on 25 strokes with a large paddle with which he always starts and ends each session.
I gained a great deal of respect for the lowly bath brush that day. And I can't wait until the next time.
