Surprise make-outs: Fantasy

Surprise make-outs were surprising! Especailly when you discovered mid-session that you were making out with a vampire. A quick round of spin-the-bottle seemed harmless enough, but when Rob, the new kid at school, the one with the skin condition that got him excused from gym, was kissing her--suddenly she felt something hard shooting out in his mouth. He pulled back and clapped a hand over his mouth, his eyes wide with--embarrassment? "Hey, let me see?" she said, leaning forward and pulling his hand down, and there they were--two quivering little points. "Sorry, I'm sorry--"
