Inspired by @ragnarlothcat 's fanfic 'à la carte' ♥, more specifically, this scene:
He leans across the bed and captures Anakin’s lips in a gentle kiss. Anakin can feel his cheeks heat, but not from arousal (or not only from arousal). The soft treatment is making him feel precious, like he’s something special and fragile. There’s a tightness in his throat he can’t explain so he opens his mouth and sucks Obi-Wan’s tongue to drive the feeling from his body. Obi-Wan responds perfectly, digging his fingers into Anakin’s jawline and licking against Anakin’s upper palate to make him moan, the sugary taste of his mouth like a drug.
