I love getting bj's (wife doesn't give bj's and I miss them now) but rarely am able to cum from on. When I do come its usually from very forceful throat fucks. I love having someone worship my cock. It makes me very hard and makes the head swell much bigger than normal. I had a gf, when we met she was married and I was single, after several years I got married and I broke things off for awhile but we saw each other on occasion after she divorced and moved away. She loved being dominated. We would explore and fuck for hours. She would allow me to fuck her throat and cum. Then she would continue to suck to keep me hard or get me back up so I would fuck her some more. She come into town one day and we met up. I took her to a secluded spot in my truck and we started making out. I would eat her pussy and she would have always have multiple orgasms coming one after the other. On this occasion instead of begging me to fuck her she crawled off the seat of the truck, knelt down in front of me and started slowly sucking on my cock. After a little while my cock was throbbing and I wanted to grab her but I restrained and let her continue to work. It only took a few more minutes and I cumming, shaking and convulsing. My cock was so sensitive but she kept sucking. Typically I would get a little soft and she would let me cool off a bit then start playing and sucking, after the sensitivity went away, to get me hard again and we would continue playing. This time she swallowed my cum and kept sucking, not letting me pullout. My cock didn't go soft and she actually increased her stroking while sucking the head of my cock. Before I knew it, I was shooting and even bigger load down her throat. I had to hold myself up with door and steering wheel. My knees were weak and I could no longer stand. I was shaking and about to collapse and had to stand her up, so she would stop, and I could regain my senses. I imagine this is what its like for women who experience multiple orgasms. I wonder if we had been laying down and if she continued, would i have been able to cum 3 or more times in a row?
