Summary: Lust as ruled by physics.
In the two-point-three-three seconds after orgasm, before his brain functions again, Radek postulates lust could be quantified and calculated according to one of the first rules of Thermodynamics. Lust expands inside him like an alkali metal, until there's no choice but for him to mold around it. It changes him, every time the temperature they generate reaches zenith. His body, his core of being, is not meant to be stretched so, and when the temperature drops as quickly as it had raised, the contraction of lust is worse.
It leaves a hole which can't be filled by anything but Rodney.
