Well, we could just leap straight into making out.

But a flirtatious slow burn could be more fun. Little brushes of skin to skin contact, footsies, hands brushing thighs... leading to interlocking fingers, palm to palm, then cuddles and nuzzles...
Couple that with lots of soft smiles with half-lidded eyes, a shared awareness that we both know where things are going.

I might use my usual tactics when I want someone to kiss me : hug them, pull away a little, keeping my hands on their sides, looking them dead in the eye and saying "Hi~". Usually works

So, the question is, how do YOU imagine it starting, Luce~
