I have to dissagree with speculum... only because I love having one in me. Nice and cold getting shoved in then being spread wide open so that no matter what I can't prevent you from entering my body. Spread so wide open that I feel like I'm being ripped apart- being left in that state until I'm sore. Being left on my stomach, with a speculum deep inside me, spreading me so far open that the speculum won't spread any wider, legs tied wide open on the bed, alone. If I move the speculum will pinch and hurt in a very bad way... lips clamped to the edge of the speculum. Then, just to add some fun into the mix.... have 6 large metal ben wa type balls shoved in to stretch the deep inner canal wide open and have a large toy shoved in to keep everything SNUGLY in place- adding weight to press against my stretched clit. After 30-60 minutes of being left alone in that state (of course, there are clamps on my breasts and nipples too- that I'm laying on, crushing, pinching, cutting off circulation to make them even more sensitive), having the toy removed, getting flipped over, and then fucked with the speculum still in place, balls still in place, clamps on lips and tits still in place.... talk about OMG MIND BLOWING ORGASM!!
After all this, my lips are swollen for hours so when I walk they rub together and cause pain in a great way and the pelvic bones are sore in a great way and everything is overly sensitive- causing pussy juice to run freely, which is a turn on, which gets the whole thing going again...
So, in my opinon, speculum is a very very good thing.
