((Warning: Very, very dark and quite non-consensual sex.))

Leonard heard them. He heard Spock and that woman moaning, heard the sound of flesh slapping against flesh, and felt physically ill. He wanted to scream, cry, and run away all at once, and he didn't have the guts to do any of it. Their bond was frayed, and each time Spock fucked Zarabeth, it grew weaker. And Leonard's heart was bleeding to death.

This was it, then. Spock's revenge for Natira. But Leonard had never slept with her, and what with him growing weaker, he doubted he ever would have. Still, he felt guilty, which was why he didn't fight. Spock didn't even know what he was doing. All Leonard wanted to do was die, but the bloody Vulcan wouldn't let him, kept him alive and insisted he stay where it was warm. So he had to listen. Again, and again, and again, and he couldn't even hate the fool that followed the clamour of the Vulcan group mind, whispering to him that fucking a woman was better than a man, because that would create many more Vulcans. Only it probably wouldn't, because they might not be compatible. Tell that a Vulcan in heat, who ignored the existing bond because his damned nature forced him to do so in this frozen hell. Spock came to him stark naked, and Leonard turned away, pretending to be asleep. 'Doctor,' Spock said, and it was too much. He remembered all too well how Spock had been angry at him less than a day before, but he'd rather the man killed him than having to listen to them fucking one more time. He got up and rammed his fist into his gut, as hard as he could. He still couldn't bring himself to ram his knee into his unprotected groin, although he had planned to. Damn love.

'That's for calling me a cheat.' He turned away and waited for the blow. Instead, he heard … a sob? He spun and found Spock on his knees, offering one of Zarabeth's skinning knives.

'I … I do not know what is happening to me. I do not know … I should never … I am so …' He finished none of these sentences, and Leonard felt the anger drain, giving way to despair and weariness and a compassion he didn't want to feel. He took the knife and flung it out of harm's way.

'But I know, and I told you before. It's not you, nor me. Nor even her. It's this time. We need to try and get out. Spock. Look at me.' The Vulcan did as he was told, and Leonard had to swallow hard when he saw the tears. 'If I still mean anything to you at all, help me get out of here, come back with me to our time.'

'For what? I lost all that has meaning.' Leonard felt his own lip quiver.

'No. If you do as I keep begging, I swear I'll find a way to forgive you. It'll be the most difficult thing I've ever done, but I'll do it. Just stick with me.' And somehow, Spock did, and Leonard kept his promise.

Her body was pliable and soft and nothing like Leonard. He had come inside her arse eleven times in the past three days. She was bleeding when he fucked her, but he refused to take her vagina after trying that for the first time. Her back entrance was more akin to what he knew.

Like this, he could imagine Leonard was caressing him. It was Leonard, who was moving against him while being taken – even if in her case it was more squirming than anything else. It was Leonard, tied to the bed but never out of control.

The truth was more bitter. Zarabeth was not him She was raw from his assault on her body. She had consented to sex, but not to this, even if she thought so. He hadn't physically forced her, no. But he had placed a need in her mind, a need for him that was stronger than the physical pain she must feel when he took her. She screamed, and there was no pleasure. He left her when he knew that this time, she wouldn't wake from her unconsciousness. He felt guilt. He had never treated his Leonard like that. He had been rough sometimes, but never brutal, and occasionally, he had got as good as he gave. Leonard could be quite forceful, and Spock had enjoyed surrendering control on one occasion or the other. But Leonard was gone, and so was his control. This woman wasn't a good person, she was a brutal killer. But no one deserved to die like that. Not even her.
