How do you fist a girl? Well, make sure you have lots of lube at hand, better to wear a rubber glove just in case, and there you go. Make sure she’s comfortable and relaxed. Start with inserting one or two fingers and move slowly. Work up the number of fingers and digits as long as she feels okay. If the two of you are smart, you can finally get down to deep fisting!
