I Was Learning How to Fist but My GF Asked Me to Try on Her

I was writing an article how to fist a girls in pussies and my gf was really bored waiting for me. She insist to try this teqnique on her because before she's never got fist! First, her pussy was really tight but after I fit there my whole palm, she really enjoyed the process! She even squirted over my table haha ;)
