Dead End in Norvelt Steaminess Rating

Exactly how steamy is this story?

G

While Jack has a crush on Mertie-Jo Kernecky, nothing ever happens in that realm. There's some mild (and awkward) verbal flirtation on his part. Oh, and a brief description of Mertie-Jo's "tanned shoulder" (21.5).

There are also a few fleeting references to kissing (when Jack's mom jokes about him kissing Miss Volker).
