Anal with a clear double dildo: 13.3" length and 4.7" circumference. I start out by fingering my tight asshole. Dildo insertion was a struggle, resulting in multiple failed attempts. Finally, the dildo made its way through and pain struck my bum! It took several minutes for me to adjust to the sensation before I could truly enjoy myself. Using my vibrator allowed my body to relax and loosen up to the dildo. I was then able to feel immense pleasure from quicker thrusts and orgasmed quickly! Twice!
