There was definite passion there and want for them to enjoy together. To please him and give him pleasure, to have him give her the same. Loki would likely not recognize love in herself for some time, as a proper 'lover' anyways. She was sometimes still baffled that she could care for others, and that it had not turned out too painfully yet. Mostly.

But the thoughts of the one complicated situation were far away with Puck there with her. In his arms, loving her and loving with her and letting her love him. Gentle kisses, soft, mixed with fire that tried to convey that yes--Loki wanted this, Loki cared--that Puck was special. It was new, and frightening and exciting all at once.
