Best and longest orgasm in my life, once I finally got there. Not gonna lie, I typically finish pretty quick and so does my wife. I don't typically get coke dick (literally once when I started using), but also not usually horny when I use, so it typically just makes me last a little longer if I do end up having sex. Last year on vacation with a buddy and his wife, he gave me a Viagra (50mg) and told me "I don't need it, but the nut is amazing. Try it" Did some quick research on interactions, couldn't find anything discouraging aside from the usual "don't do drugs" so I popped it.
Wife went to bed about an hour later, I finished my drink with my buddy and headed to bed too. She's waiting on the bed in lingerie. Motherfuckers set me up

We get to doin the damn thang. Oral back and forth, every position, front door, back door, I'm a goddamn porn star, except I just can't get to the money shot. We used to fuck like this when we were younger, I would cum but I was able to keep going and stay up through about 3 nuts. I'm 40 now, the little guy is worn out and can't keep going after busting, he needs a few minutes to go again. So I don't have the cardio or stamina like I used to. After about an hour and a dozen or so Os for her, I gave up. I'm winded AF and pouring sweat (and a little worried about my heart

). Went back outside, had a couple smokes, another couple beers, and some high fives with my friend. Went back to bed and she asked if I wanted head (my favorite) until I got there. Of course I did... Took about another 15-20 minutes and it finally happened. That build up when you know it's coming that usually lasts what, like 30 seconds, lasted about 3-4 minutes, and then the explosion. Atomic bomb explosion. What's an actual orgasm last? Maybe 10-15 seconds... MAYBE. This was a solid minute plus of blissful uncontrollable shaking spasming and shooting the largest load that has ever came out of me. When I was finally done, she says "holy fuck babe, I had to swallow 4 times".
I'm not saying do it, but I'm definitely not saying don't do it either.
