Flat > Tip

If you were dared to lick something you didn't want to lick, something like a toilet seat or a park bench, how would you lick it? With the tip of your tongue, right? Why? Because you know you don't want it touching your tongue at all, so at least the you've got some consolation in knowing that this gross thing is only touching the very tip of your tongue.

Now think of something you like licking. Ice cream. You don't use the tip of your tongue, do you? Why not? Because you like ice cream!

Same goes for your guy's dick. Don't use the tip of your tongue unless for something specific that he likes. In using the tip of your tongue, you're partaking in body language that says "I'm doing the bare minimum in order to complete the dare..." Using the flat of your tongue is body language that says "I fucking love this dick!"

Like shown above, stick your tongue WAY out. Press the far back, flat part of your tongue on his cock. With TONS of pressure. Almost smashing your face into his dick or his balls. He'll absolutely love it.

But for the love of god, don't use the tip of your tongue.
