Got my GF horny one night and convinced her to let me try *******. I used a lot of lube and soon had three then four fingers inside. after playing for about 15-20 min I managed my thumb as well, getting the knuckle part of my hand was proving more difficult, but at last it slipped in and I heard her moan like never before. the best part was that she couldn't tell exactly how much was in at any point as I never let her look. she did mention some slight discomfort as my hand slid in but never had serious pain. when my hand was in I allowed her to look and loved the surprise on her face. I ****** her just after that and everything had gone back to the way it was before, only difference was she moaned like never before and had the mother of all *******. now she asks to be fisted quite often.
