Hey, sexy chess is completely acceptable, metaphor-wise.

She brings her other leg up, basically holding him in place, and keeps the kissing going. Chess is also an apt metaphor because she is having some very definite moments of "oh god my planning only got so far," which is... also fairly like chess for her. But kissing is a good holding pattern, yes.

Kissing and some more kissing and then: "Pants. They're still on you."
