Well believe it or not we had one mature lady who had 45 orgasms over a 4 hour period,she just had to have a few breaks due to the exertion and towards the end no vibe was used, i did not touch her ,i could tell her to cum and in a couple of minutes she would cum.
Some ladies will go into sub space during the process of continuous orgasm,these women really do have a fantastic time.
I have played with numerous women who could rattle out 5 to 10 orgasms before needing to stop and may of those were regular squirter's.
