During ROTJ, on the Millennium Falcon
It had been so long, so long.
Her eyes closed, she revelled in his touch, his presence. Leia was gentle as she explored him, aware of the carbonites effects.
Han appeared to be recovering nicely, pulling her towards him eagerly.. The comfort of his warmth pressed against her, his lips... She had missed this desperately.
Surrendering to the moment, her shirt (really his shirt) was tossed across the room. As Han's lips travelled, Leia reminded herself to retrieve it later. It had been an immense comfort.
Then coherent thought became impossible as Han's exploration of her body grew more intense.
