At the risk of dupping, I must post this one. video9488/multi_orgasm_on_sybian_anal is the last part of the address, and she comes so many times, she's nearly crying at the end (looked to be from a powerful double-header orgasm that almost cramped her up). If I were a woman and saw this video, I'd do whatever it took to get one of these sybians. Obviously, you don't have to go so hardcore with it, but when you feel up to the challenge, it's up to the task.
Reminds me of one of the stories I published (COB) where a futuristic sybian-type machine of harmful strength made the main character pass out and dream mind-altering dreams. Had I seen this video before I wrote that (a couple years ago), I'd have been even more convinced this reality was just around the corner--letting someone come so hard and so long that it actually changes them psychologically (and I'd not be skeptical if a study showed long term use would alter your chemicals related to sex).
