I thought this game had a plethora of amazingly well done/sexy voices! The voices are what simply *make* many of the characters.
My list, in NO particular order:
1.
Brynjolf: like, seriously. Need I elaborate? That voice is melted chocolate on lightly toasted marshmallows. Mmmmm!
2.
Mercer: again, regardless of his badness (which I love about him actually), his gruff and leering voice is friggin' sexy. I currently and will always have him as a follower, and I especially love being married to him in one of my files and traveling/being spousal with him. The more he talks to me, the better! 8D
3.
Marcurio: something about that even-toned, smart aleck voice that I just love. He's so articulate, and his voice is just very, very easy on the ears, as much as he is easy on the eyes.
4.
Nazir: I too love the man's voice. It's rich and sarcastic and maybe it's just the Skyrim Gamer Poop's fault, but DAYUM

It's sexy as all get out.
5.
Tullius: I may well be in the minority but I personally find his voice sexy as well. It makes the Imperial side quests all the more awesome. ;D
6.
Molag Bal: again, another one I need not elaborate on. His voice is the very definition of DAYUM

I did his mission purely because he seduced me with his voice.
7.
Clavicus Vile: I just love his voice. It's adorable and vaguely sexy as well. Made me wish sooooo badly I could have met up with him on the road sometime after his quest, like it sorta sounded like could have happened. Alas.
8.
Spectral Assassin: another
DAYUM! explains all. I can't get enough of Lucien's voice. I just...GUH. UNF.
I'm sure I will think of more later, but the above are the ones that come immediately to mind.
