It takes time and lots of lube. I started with a small vibrating anal plug, then I went to my wife's g spot wand, it was perfect length and curve to hit it perfectly. I leaked tons of precum with it and had non ejaculation orgasm. Then I moved on to her bigger longer blue vibe and that did the trick. I could feel the orgasm to start building and then it just started to flow.... I didn't think I could stop, the more it vibrated and stroked the prostate the more I came. It was was a great feeling.
It's been a while since I've had another but hoping she pegs me to my next one
