My new futanari doll triggered a prolonged orgasm

After a while, the new doll I've bought came, and I was excited to try her. I have a fetish for futanari and she is just perfect for that. She is very beautiful and her huge cock is just amazing. I've been waiting for a doll like this for a long time, and now she is finally here. As soon as I took off her clothes, she started moaning. The thought of fucking a doll is quite unusual, but it's exactly what I needed. I took my dick in my hand and started fucking her. The sensation was incredible, and it didn't take long for me to cum. But the surprising thing was that it triggered a prolonged orgasm. I had never experienced anything like this before. I continued fucking her, trying to get rid of the feeling, but it kept coming back. It was such a strong orgasm that it left me completely satisfied.
