I find it is the best and easiest way to have 2+ orgasms and if your prostate is stimulated it feels amazing. I can squirt out 3 or 4 loads and then immediately have another orgasm after another 10-15 seconds being jerked, sucked and/or fucking my girl and each orgasm is more intense than the last. I find I can cum the most if my girl fingers my prostate or if I have a well fitting buttplug in there. It feels particularly intense if you squeeze your pc muscle hard each time you throb during your first orgasm. I squirt bigger with this method than I do being manually stimulated as I orgasm.
I can cum 3+times if I pull out or when I am sucked&jerked off and then the gurl stops and holds the base of my cock. I usually pump out at least 4 juicy squirts the first time and then I go again. After the third orgasm I shoot blanks, but my cock still throbs super hard. It is the best way for a guy to have multiple orgasms.
