Well, since I can't just say ALL of them:
Pornstar= I like the idea from above. Brandi Love's with my left, Julia Ann's with my right, Miss Hybrid's with my mouth(just to suck on those nipples....) and Naughty Allie's with my dick(so I can cum all over that beautiful face)
Actress= Christina Hendricks, of course! And also Sofia Vergara, damn hers are NIIIIICE.
Singer= My goddess, Christina Aguilera.
Diva= Trish Stratus(fine piece of Canadian ass)
You know, I change my answer......ALL of them!
