I was getting a blow job from a friend. She put a pillow under my ass and went from licking my balls to licking my ass. Then she probed me with a finger. It felt so good physically , but so wrong mentally. She told me to just relax. I relaxed.She went deeper and hit my prostate. It felt unusual,but so pleasurable. I ended up cumming so hard and she sucked me dry. It was a toe curling and I had a whole body orgasm.
