Is this about first kisses, or any kiss that’s perfect?
I imagine a kiss that begins with a bit of teasing—sort of each partner faking towards the others lips, then veering off to kiss something else. Eyes are watching each other, too, looking lips, back to eyes, wondering what the other will do. Suddenly one person can’t stand it any more, and they pull the other person’s body so close, they are stuck together in one long body kiss, while the lips first, due to the sudden rush, press to hard against each other, but then they pull back feeling lip to lip, just lightly, opening slightly, tongues testing the waters, so to speak. It gradually gets more and more intense, and other parts of the body get involved.
Ok, so that’s en erotic kiss, not a chaste one. But to me, that’s a perfect kiss. Or it would be, if like Valentine Michael Smith in Stranger from a Strange Land, we could magically discorporate our clothes.
