I sometimes feel that the slave-cunt should not be allowed any pleasure while being taken or servicing Me and any vaginal stimulation should turn to some Torture so it knows it’s purpose and place.They are all pretty effective.
Personally I like enough attention on my clit (and tits and nipples while we're at it) no matter what method is used.
Nettles are also interesting to use (on the clit as someone mentioned but can be inserted too).
I also like the use of needles and clamps.
If we're talking duration I like forced orgasm play. Preferably with clit stimulation and anal and vaginal machine fucking where the pleasure will quickly turn to pain.
