When his mouth lands behind her ear, she shudders hard. She’s never been able to control her reactions to that spot; it’s /so/ sensitive. Instant turn-on. But his hands are sliding up and down her leg over her skirts, and he’s still kissing her bare skin, which brings desire in a quieter way, at least until he breathes in, which tickles. Summer giggles, and once she’s started she can’t stop.
Percival starts laughing as well, first nervously, and then genuinely. He grins and leans forward to whisper in her ear. “What’s so funny?” But the shaking from the laughter is doing interesting things, and he quickly shuts up, biting his lip.
“You tickled me,” she manages, between snickers, until her eyes fall on him biting his lip. That, finally, stills the laughter. Summer leans forward, eyes flicking between his eyes and his mouth, until she can kiss him, sink her own teeth into that lip. She can sense his body’s reaction, and smothers a smile.
