My girlfriend's vagina was not able to accommodate my penis

The other day, I went to my girlfriend's house and we decided to spice things up in the bedroom. I had been craving her tight pussy all day and I was ready to take her right then. As soon as we got to her place, we headed straight to her room, where things started to heat up. I started undressing her, ripping her clothes off, and she was more than eager to help me. Once she was completely naked, she eagerly took my cock in her mouth, sucking it hard. I could feel her throat working on me, making me even harder. After a few minutes of deepthroating, I decided to plunge my dick inside her. But to my surprise, her pussy was not able to accommodate my big cock. She was so wet and tight that it was difficult for me to go deeper. I pulled out and then I fucked her from behind, pounding her pussy hard. She moaned in pleasure, enjoying every moment of it. After a while, I came inside her, filling her up with my hot load.
