Starsky's performance as the cocky pimp Rafferty isn't entirely for the cops' benefit. Black satin shirt open to the navel, tight white pants: he's all too aware of the effect he has on women - and his partner.
He leans back; arrogant, laughing, exposing yet more chest and crotch. Hutch is dying to reach out and touch... something. Something with hair... Anything.
Socked feet up on the desk, toes flexing. His muscled thighs ripple with the action.
Hutch is caught looking. A blush creeps up his face, into his hairline; his groin stirs.
Starsky whispers, "Gotcha!"
Hook, line and sinker.
