Tantra has a great lesson for cock suckers. It’s called Tantric Mouth Congress. When, holding the man’s lingam with his hand, and placing it between his lips, he moves about his mouth, it is called the ‘nominal congress’. When, covering the end of the lingam with his fingers collected together like the bud of a plant or flower, he presses the sides of it with his lips, using his teeth also, it is called ‘biting the sides’. When, being desired to proceed, he presses the end of the lingam with his lips closed together, and kisses it as if he were drawing it out, it is called the ‘outside pressing’.
When, being asked to go on, he puts the lingam further into his mouth, and presses it with his lips and then takes it out, it is called the ‘inside pressing’. When, holding the lingam in his hand, he kisses it as if he were kissing the lower lip, it is called ‘kissing’. When, after kissing it, he touches it with his tongue everywhere, and passes the tongue over the end of it, it is called ‘rubbing’. When, in the same way, he puts the half of it into his mouth, and forcibly kisses and sucks it, this is called ‘sucking a mango fruit’. And lastly, when, with the consent of the man, he puts the whole lingam into his mouth, and presses it to the very end, as if he were going to swallow it up, it is called ‘swallowing up‘. Striking, scratching, and other things may also be done during this kind of congress. The congress should only ever be performed by a male on a male.
