I'm such a slut for pain and overstimulation!  These suction cups on my nipples and clit are perfect in combination with my womanizer to overstimulate my clit and nipples as much as possible!  I suction them to their max capacity to where I can barely take it, making my nipples and clit extremely swollen! Once my clit is super sensitive I have a very overwhelming orgasm with my womanizer keeping the nipple suckers on.
