The Doctor couldn't move to make this go any farther, even if he wanted it to. To move one hand was to release the Master's, and the other was in the Master's grip. They were trapped in their own need to control the other. It was intoxicating and, in a way, extremely arousing. He let his hips move upwards and let out a groan against the Master's growl.

The Doctor was aroused. That was really inappropriate. Hell, considering what was happening with them, it probably wasn't even tasteful. But he wanted---he wanted to just feel. Maybe it was the human side of him. Maybe it was something else. It didn't matter.

"Master." He growled his name into the Master's mouth. The way the Doctor said the Master's name wasn't like the way the Valeyard said his name. There was anger and hatred and desire in there, all the things the Valeyard only thought he understood but didn't. The Master made the Doctor hungry for something. Something that was more than just physical. It was more than the Valeyard could understand.
