Keltham pounces on his oblivious girlfriend and kisses her; and hurts her as best he can, without using any tools, squicking himself out, or being the Queen of Cheliax.
They are not going to advance all the way to sex, though. Keltham has further work ahead of him this evening; and frankly, he is not sure he can make it through all that, if he is not sufficiently horny to remember why he's trying. He does moderately expect that, if things go well enough, he can get fairly thoroughly laid.
