I love the opening teaser of TNG's 4th season episode Qpid.
Picard finds Vash waiting for him in his quarters. She saunters across the room toward him. The sexual heat in their eyes is palpable. (The fact that Stewart and Hetrick were involved at the time of filming might be why.
) She tenderly strokes his face bringing him in for a soft kiss. She plucks the horga'hn from his grasp dropping it onto the chair and replacing it with herself. Their lips meet again in a deeply impassioned kiss.
