"Fine," Buffy said, crossing her arms. "You fell on Spike and your lips mashed together. Explain the tongues."
"I, um, bit my tongue when I fell?" Xander looked towards Spike for approval. "Hard. It bled and Spike was hungry so… Ow! Why'd you punch me? Oh… That's not what happened."
"Cause I wasn't sure he'd let me suck something else," Spike grabbed his crotch, "on the first date."
"Yeah," Xander said. "Wait. What? You were gonna?"
Spike slowly slid his tongue across his lips.
Grabbing Spike's arm, Xander raced off into the night, calling back to Buffy, "Gotta go. Bye."
