Allegedly, If one was good at getting their fist into their gf, she would hypothetically claim that, "it is the most intense feeling" she had ever had... further, that it forced her to 'orgasm constantly until the fist was removed'. With that big of an object in the vagina, the G-spot, all of the vaginal wall as well as the cervix is constantly stimulated. Any of these areas can produce orgasm when stimulated individually, so obviously the intensity would be increased when all are simultaneous. Add a tongue to the labia and clitoris and her insanity is guaranteed. Female genitalia is amazingly resilient in that even after a fist or even delivering a baby, intercourse still produces friction. However, in the case of fisting, like anal sex or
any sex, would obviously have to be consensual, very conscientious on the penetrator's part, slow and WELL lubricated.
