「Flow」with「the small meat, the miniature」of the bigger meat, describes the moments prior to and during orgasm related to the clitoris (see 指). DISAPPEAR, VANISH, TO HAVE A NEED and TO SPEND TIME DOING combined with TO REMOVE BY RUBBING as when using an eraser all describe the moments just prior to and during the female orgasm response of many women when the clitoris retracts a bit:「Just as men's testicles go AWOL close to orgasm (the testes need to be retracted for him to orgasm), the clitoris often hides under its hood when you're nearing orgasm [referring to the female subject, not the partner]. Given it's a slippery little bugger [ed. note: buggering actually occurs within the anus] at the best of times and that most men are literally in the dark when performing oral sex, this can cause more anxiety than an empty beer fridge on the night of the World Cup final.」
　「If this happens to you [referring to a male partner, not the female subject], don't panic—and don't go looking for it either! Just keep stimulating the general area in which the clitoris was last seen or gently massage her tummy, pressing your palm downwards towards the vagina, to make it 'pop' back out again. And remember, it's absolutely imperative that once she starts to orgasm, you don't stop stimulating her or change what you're doing. Her orgasm is roughly three times longer than yours and it's common for men to think it's all over when, in fact, it's only just begun. And here's the thing: while you'll continue to orgasm once you've started, even if she stopped right there and walked out of the room to make a cup of tea, women are different. If you stop touching or licking her at the start of her orgasm, it's very likely you'll abort the rest of it. This is about as satisfying as having one bite of a chocolate when you were planning on scoffing the entire box.」

　EXTINGUISH means to put out the flame, cool the heat when HAVING A NEED and SPENDING TIME to REMOVE BY RUBBING in order to quell the desire, a clear reference to erotic clitoral stimulation until completely satisfied. CONSUME means to eat or drink fluids, to become engrossed or obsessed with an action, to waste time, to burn with flames, or to use until gone. SWITCHING OFF THE POWER and TO DIE OUT seems to be a clear reference to erotic clitoral stimulation ceasing prior to becoming completely satisfied as described above when an inept male's tongue is the source of stimulation, being cheated out of one's chocolate, as it were.
