Had a lady do this technique on me and oh my god it was intense. She would basically edge me and stop until I just eruptdd like a volcano in her mouth. She always really got off on it good times.
My friend would get me hard sucking only the head, then use middle finger and thumb around the head vigorously. OMG, I would cum so hard. Only time I ever came twice, she kept going on my head after I came. It was almost painful as she continued. Then I felt it, deep down as she made me shoot a hard thick single rope, it felt like my balls were going to explode.
