One night my girlfriend and I were cuddling naked in bed, watching a porno to get both of us into the mood. It was a whole bunch of stuff on one disc for both of us, full-on sex, lesbians and both women and men masturbating. In one of the scenes she was getting into, it was showing a guy that barely looked 20 masturbating in his kitchen, spying on a woman in the pool. He was completely naked and was stroking a very hard (and very long) erection. This kid had to be at least 10 inches long. It was really getting her turned on, but I admit my hand was moving up and down my penis along with him. I am straight, but seeing a guy enjoying himself like that makes me want to start masturbating as well. He kept growling and stroking and his pre-cum was running all over his hand. He would stop, lick it all off and then go back to stroking. At one point, he even sat down and started licking and sucking the head of his own penis until he came.
She then asked me 'ever tried it?' I asked what she meant, and she giggled and asked if I ever tried my own cum. I told her no, but I have always wondered about it but could never bring myself to do it. She then asked me if I wanted to and I wasn't sure, but I said if she really wanted me to and would help me I would. Just telling her I would taste my own cum had my penis throbbing and burning hot.
She pushed me on my back and spread apart my legs, and I put my hands behind my head. She then started masturbating me slowly, massaging my balls and pulling the skin down as tight as it would go, making me let out a loud 'UNGH' sound. Since I was already very horny, it didn't take long before a big drop of pre-cum squeezed out of my dick. She wiped it up with her finger and asked me if I was ready. My heart was pounding and I told her I was and stuck my tongue out. I closed my eyes and she wiped it all off. I sucked on it and told her it really wasn't all that bad. She asked me if I wanted some more, and I smiled and nodded. She kept on stroking and edging me, then she would stop and milk me, squeezing out all the pre-cum I could make. She would wipe it, then stick her finger in my mouth and I would suck it all off like a hungry baby.
She kept going and my mouth was coated with my own lube, but pretty soon I told her I needed to cum. She wanted me to lick it all up, so I told her to get on her back, then I straddled her and started stroking as hard as I could, blowing a massive load all over her tummy. I was a little hesitant to do it since I came, but she kept telling me to do it, so I leaned down and licked it all up which made her squeal. It didn't taste as good but still wasn't awful, and not only that she was amazed I did it. I crawled up and kissed her, my mouth still sticky with sperm. After I did that I fingered her to a couple of orgasms.
Since then I have gotten more used to it, and now it's almost a normal thing to lick it off of her. I know it may seem gross, but it's not that bad and I figured if she did it, there's no reason I shouldn't. Not only that, there's no mess to clean up afterward!
