I'm stuck and out of ideas. I need advices

I'm stuck in a roleplay, I don't know how to continue the plot.

The role play is simple. My character is a generic succubus and my partner is a fox-boy, like a kitsune or something.

Currently I'm wearing nothing but a kimono, he wears one too but more covered. He is sitting on his knees while I brush his long hair behind him.

I don't know how to make the plot more spicy.
