Spock/Uhura
La Cadenza by
tehlanes (Spock/Uhura but more like Uhura/herself, NC-17, 3351)
Summary: Nyota knows that sometimes going it alone is the best way to get it done.
Notes: Uhura pleasuring herself while thinking of Spock is just a hot concept on its own, but this story brings it to a whole new level. Even though Spock isn't directly involved in the sex here, the desire and chemistry between them is undeniable.
