long dildo slides so deep I lose control over my juicy butthole

I got an amazing orgasm when I lubed my butthole and dildo with new fisting lube. It easily slid into me so deep and tickeled my anal walls that I instantly started having an orgasm and shivered like crazy. In the end I fart alot and show of my prolapsing rosebud when I pushed so hard the speculum fell outta my hole with lots of lube juicy
