The fear came roaring back when Spike's fingers closed over Ianto's nose, and he struggled to pull in a breath that wouldn't come. He trembled as he pushed back against Spike again, closing his eyes as he swallowed hard, trying hard to push down the panic. Feeling the arousal build higher, even as his mind screamed he was going to die.
At least I'll have one damned good fuck before I do. The thought ran through his head abruptly, and his eyes snapped open. Ianto relaxed into Spike's hands, and he pushed back with a bit more enthusiasm. He was bloody well getting a good time out of this.
