Guill's eyes are feverish with need for the darkness in Tuvok's mind. When the Vulcan lowers his barriers a little, Guill gasps, his face flushing. He stares at Tuvok hungrily, in awe of his control; he longs to break it, tendrils of his own mind reaching out to tempt that darkness into his starving soul.

Tuvok sinks into Guill's wild eyes, tries not to notice the sculpted lips wet and open. His control slips further - not by intent this time, and he knows... before the night is over, he will give Guill everything he needs. Everything they both need.
