I also find kissing (especially well written kissing) extremely erotic, and the kiss in McKay's "Too Wise to Woo Peaceably" (found here (http://remembrall.slashcity.net/)) was what sucked *g* me into slash.

McKay (scribbulus_ink) always writes beautiful kissing scenes. Her ensnared_senses and arionrhod's cocoa_cardigan from the_leaky share some wonderfully hot kisses, which lead to very hot other things. :D
