It goes in the fridge until cold. You then take it out and unwrap it whole on a clear table or desk in front of you. Having carefully unwrapped it, totally nude in front of you, your eyes travel over it for a while. Admire those sharp edges and those soft curves. Like you, yourself were admired at 18. You breathe in that sweet, rich, earthy smell, all the while being given off by the dark, smooth skin of the bar spread out beneath you.
Then, when it needs to be held you pick it up. You position it length ways under your nose, curved side on top, like a mouth organ just under your nostrils about to be blown. You push your tongue out and tentatively lick the underside, tickling the bar while your saliva glands pulse to attention. Then, holding the ends firmly like you would a stick of sweet corn, you gently bite down on the acute angle where the curved edge rolls into the bottom. You sweep this piece into your mouth with your tongue while gently moving the bar along, biting, licking, sweeping......until....you feel the curved end separated from the bottom, just held together by the quivering, soft, melting centre.
Now, the bar is at your mercy, you flick your tongue along sweeping it in the gap, prizing apart the two edges of chocolate while the white, fondant cream can hold back no more. Into you, everywhere, dripping down, around your lips. Now inside you, that white, succulent cream, oozing, jetting, pulsing into the very centre of you.
A nice Early Gray afterwards is strongly recommended.
