Son trou du cul était trop étroit, mais pas plus

My girlfriend was with me in my bed when I shoved my finger into her asshole. It was too tight that I had to push my finger in. At that time, we decided to make her asshole lose so that my cock can go in and out easily. I shoved her favorite toy in her asshole and played with it for a while. Once I saw her asshole was a little bit bigger than before, I shoved my cock in it and fucked her.
