Here's a drabble (plus one word) for ba_rosebuds , prompt "Tease."
Set in mid- to late S3, Angel muses on the impossibility of his relationship with Buffy.
She isn't doing it on purpose. She can't possibly know what kind of effect she has on him, even now. She doesn't understand the dangers of a single kiss, how he wants to-
-crush her against the wall, tear off her clothes and bury himself deep within her, kiss away her worries and whisper words of love into her ear as she shudders around him, to turn every peck into a desperate, passionate embrace-
He tells her he's leaving for her own good. He never explains that he needs to get away, too, before his love for her is his undoing.
