My son fucked me in the ass this is my first experience of anal sex

The first time I had anal sex was when my 18 year old son dragged me into his bed and fucked me in the ass.

My son recently gave me my first experience of anal sex, and I must say it was quite unexpected. To be honest, the thought had never crossed my mind until he brought up the topic.

When we discussed the idea further and explored mutual consent, curiosity got the best of us both.
