I apologize for the long silence. Unfortunately, due to life and other interferences, the next story I post may be my last. Thank you everyone for your support and encouragement.
This is a look into Sara's head, probably during early season 6
Not mine
He was keeping a strict safety distance between them at work. But then, so was she. Sometimes she felt that she must be as obvious as a neon sign flashing on her forehead saying "Sara Sidle got laid yesterday" with an arrow pointing to Grissom. At other times she realized, rationally, that they were being overly cautious. Really, she had more physical contact with Brass at work than with Grissom, and they didn't even work together every night. The two of them were being more obvious by not touching than they should have been when making contact. "Should have been" was the key. She wasn't entirely sure.
If what happened to her at home when he touched her even casually or accidentally was anything to go by, the same thing at work would probably trip the sprinklers and set off the fire alarm.
At home…her thoughts drifted. At home, hers or his, was a different matter entirely. At home she was still afraid to touch him sometimes because she half-expected him to pull away with a cold "no" of refusal. Even though he had given no indication in the past weeks that he ever would again. But that was weeks, and she had years and years of evidence to the contrary.
It was far easier to touch him once they had already started. When they were in bed and he was asleep she would touch him lightly. Usually it was small caresses on his face, or his hands if they were readily accessible. A few times, he had smiled when she ran her fingers through his hair, but continued sleeping, always. Grissom slept though almost everything, except for the smallest sound, which would rouse him instantly. He never woke when she touched him, until the day when he did.
His eyes opened and she jerked her hand away immediately, face flushing with embarrassment. For a moment he seemed confused, but then he reached out and pressed her hand back against his shoulder where she had been tracing random letters. She remained motionless, bracing for the blow that would surely fall. It never came.
He smiled sleepily and brushed his thumb over the back of her hand. "I have the most beautiful dreams when we sleep together and none at all when I sleep alone. Now I know why." Not trusting her voice after such an unexpected display of gentle sweetness, she kissed him instead.
It wasn't long after that when she accidentally brushed against his back when passing by him and a few days later when their gloved fingers touched when he handed her a tape lift. And it was ok. No alarm bells started ringing. Nobody stood up and shouted "caught you!" Because they were working. They were professionals. And such things would have been ridiculous.
