My partner and I quickly transitioned from not noticing to him pleasuring my backdoor

My partner and I were cuddling in bed when he started exploring my backdoor. I didn't notice at first, but soon he was finger fucking me, and it felt amazing. I moaned and encouraged him to go deeper. He slowly slid his middle finger inside me, and it felt so good. I was wet and ready for more. He took off my panties and started licking my clit while fingering my ass. It was intense and exciting. I could feel my orgasm building as he continued to pleasure me. He then inserted his hard cock into my tight asshole. It hurt a little at first but soon turned into pleasure. He fucked me hard and fast, and I loved every second of it. It was the best sex I've ever had with my lover.
