I wouldn't say that anything goes. I've had my cock sucked so hard I thought it would pop and that was not pleasurable in the least. One chick tried to get the whole thing in her mouth, then closed her lips tightly and sucked as hard as she could. I can appreciate pain sometimes, but not that kind of pain. Here are my suggestions. First, let me note that I find fellatio most appropriate as a warm-up exercise. Usually once I get really excited, I'm ready to stick my cock in a hot steaming pussy. However, I suppose that sucking to finish would be an interesting diversion. While guys may not respond to verbal stimuli as much as gals, any guy wants to hear how great his cock is. First, you ladies should tell your man that you want to get his cock in your mouth more than anything in the world. And tell him how hot it gets you to get your lips on his organ. And that you want to feel his hot come explode down your throat. Start by licking the penis all over. Licking the balls is a nice touch, too. The underside of the cock is the place you want to spend most of your time. Be gentle on the head because it can be sensitive, especially when you have a raging boner. There's a little place on the underside of the cock, about a third to a half way down the shaft (from the head) that is the most pleasurable. An astute cocksucker will slide her lips up and down the underside of the cock, her tongue darting back and forth between her lips, pausing on this most sensitive area. By now the guy should be rock hard. Next you should prepare for oral entry. You've got to use your hands to be most effective. Through skillful manipulation of the pubic area, you can get the erect cock to wag around a little while you playfully try to catch the tip in your mouth. Gotcha! Now you can look up at the guy's face with that "oh, now I'm in heaven" look. Now the skillful fellator will have lots of saliva, maybe a little dripping out of the side of her mouth as she lets her eyes half close in bliss. Now you should grab the shaft gently and move the dick around as the head graces your wet lips and you tease the tip with your tongue. Obviously you can still lick the underside now also. Some guttural moaning is nice too, as the sound resonates around the cock. Next you start bobbing slowly, getting more of the cock in your mouth with each stroke. The lips should have just enough pressure to make full contact all the way around. A little suction is appropriate, but not too much. It's mainly the lip and tongue action stroking the skin that produces pleasure. You should try to get the entire penis in your mouth, as your tongue caresses the underside. After a few minutes of this, the guy is ready for some more serious stroking action, the kind that can only be achieved through use of the hand. With the dick head safely embedded in your gently sucking mouth, you should jack the guy off, slowly at first, then increasing speed. You might also invite him to masturbate himself, telling him to jack off into your mouth. It's important to keep as much of the cock in your mouth as you can, while still allowing good masturbation. The dedicated artisan will keep it up even as the guy's hand is banging away at her face. Now is a good time to start moaning in earnest. It could be a good idea to rub your clit now, even bringing yourself off if possible. There's little more exciting than a lady coming with your dick firmly entrenched in her screaming mouth. It takes me a long time to come this way, but it's worth the wait. It is critical to swallow. However, it's not necessary to have much of the cock in your mouth at the moment of ejaculation. One of the best blowjobs I ever got was where the lady slowly backed off until her lips covered only the little hole as I pumped load after load across her tonsils. Some ladies can bring a guy up to the brink of orgasm and then stop, several times. This produces a building sensation that can result in a most intense climax. But don't make the poor gent wait too long. Again, an experienced woman will know when the guy just can't take it any more. An interesting variation would be to have the guy tied up where the woman is completely in control of the proceedings. She can have him begging to come. Just when he is terrified that she will never allow him to ejaculate, she finally gives in. At the moment the guy realizes she is finally going to let him come, he usually immediately shoots an initial wad with the force of a rifle. Then wave after wave of ecstasy engulf his body as his balls squeeze gobs and gobs of jism into her willing orifice. Once you're convinced you've swallowed his entire load, gently let it go. After ejaculation, the penis is very, very sensitive and further stimulation is counter-productive. Let the guy be a beached whale for a minute or two. Ejaculation saps a guy's strength temporarily, especially if it's a really good one. Once he's recovered a little, you can kiss him on the lips, or just nuzzle him. Whisper in his ear about how good he tasted. Any of you guys out there disagree? Or have any of you ladies had other successful experiences you'd like to share?
