My gf and I began to fool around as usual, but this time when my fingers slipped out of her wet snatch and touched her pink butthole she didn't stop me. She just kept moaning and groaning, her eyes closed and her behind moving in rhythm with my fingers. I needed no more hints to understand she wanted me to give her a good backdoor fuck and moments later I was fiercely ramming my fully erect dick down her tight virgin asshole. It was the beginning of a new anal era in our relationship.
