Giles reconizes the problem

"Remembers, you are a watcher," Giles told himself as he watched two perfect women almost bare their breasts to him. "These girls are you're wards. They are obviously out of control. Slayers exhibiting uncontrollable lust are fairly common. Buffy and Faith must be suffering from that. You need to remember your place and help these girls."

"Yeah, but your also a horny old man looking at two hot girls,"; a voice, that he was trying to block out, and failing, kept telling him.

Giles knew the history of this. Slayer's bodies got very worked up during fights to help them better deal with the necessity of killing others. Sometimes it got out of control and the Slayer became very aroused, to the point that may engage in activities they normally would not, like posing in front of their watcher in a contest of dares.

This had happened to many other Watchers he also knew. The appropriate action was to have the Slayer drink hot tea until they were calmed. Giles also knew that most Watchers ended up using the Slayer&'s lust as a reason to fuck her.

"Tea, or sex," Giles thought amused.

"I will have you know that a stevadore is used to describe something that can continually pump and ram for long periods of times. You can, hopefully, draw the conclusion to how that applies to love making," Giles told them with a smile. Inwardly he was yelling, "Get the damn tea" he just didn't think he would listen.
