The sexiest episode I can think of is The Enterprise Incident with the scene between Spock and the Romulan Commander.
What surprises does something as simple as a little break have for Captain Janeway and her blonde Borg companion? Jeri Ryan was born on February 22, in the year, 1968 and she is an actress who is well-known for her performance as the character, BorgSeven of Nine on Star Trek: Voyager and for this, Jeri Ryan had been nominated 4 times for the Saturn Award and she had won in the year, 2001.
Jeri Ryan had graduated from Lone Oak High School in the year, 1986 and she had then studied at Northwestern University.
Apart from Jeri my other favourites are Terry Farrell Jadzia and the few episodes with Suzie Plakson in especially as K'Ehleyr.
To add to her struggle, Janeway invites her for dinner in her quarters one day.
It will be your undoing.
