My girlfriend and I began to fool around as usual, but this time when my fingers slipped out of her wet pussy and touched her pink butthole she didn't stop me. She just kept moaning and groaning, her eyes closed and her ass 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 cock down her tight virgin butthole. It was the beginning of a new anal era in our relationship.
