I'm pretty much down for any sick and kinky thing a girl would want to do as long as it doesn't involve human excrement. If she wants me to beat the vag up then dammit i'll beat it up!
Im not a girl but im pretty sure if she likes the fist your teeny weeny would never please her but what do I know
I tried it many times with my x. I love it. fantastic feeling of fullness. It is possible for most women to enjoy fisting without pain. its a matter of takign the time needed, lots of lube and the right partner. You can find how-tos and guides on Fisting.com if you have never tried it before. Its a community site for people with an interest in fisting -both males and femails, anal or vaginal fisting. Im still learning about anal fisting. Have dared trying it out yet but I will within long. Would love to hear from people with experience.
Seems like it would beat up her pussy and make it loose. Might not want to try it on any long-term girlfriends.
