Since I seem to have ideas, here is a second scenario:
>Be you.
>Middle of Winter.
>Snow is covering the ground.
>Naturally, it is cold outside.
>You and your Gardevoir decided to spend the day outside.
>She doesn't mention it, but you can see her trembling.
>She is cold.
>Weird, considering she was dressed warm.
>As you look at her, you notice her chest crystal faintly peeking out of her jacket.
>As you have learned long ago, the crystal was one of her most sensitive spots.
>Yet, despite that, you reached towards it with your hand.
>With no warning or reason, you gently poked it with your index finger.
>Your Gardevoir's gentle, surprised "Eep!" rang through the area where you were sitting.
>The people around you seemed blissfully unaware.
>Your Gardevoir was blushing.
>Despite it, she wasn't trembling anymore.
>Or at least, she wasn't.
>A devilish grin forms on your face.
>You poke her crystal once more.
>Her blush intensifies as her face gets hotter.
>She stops trembling once more.
>Feeling your warm skin on her sensitive crystal seems to somehow warm her up.
>You keep caressing it gently with your fingers, all the while she does her best to keep her moans in.
>Despite her embarassment, you can feel her enjoying it.
>"I love you.", you breathe into her ears.
>She shudders lightly as she hears you say it.
>You hear her voice in your head.
>"I love you too."
>You keep on caressing her, all the while she struggles to keep her voice in.
>She is not cold anymore.
