Headcanon #2

At first Reiner kissed Bertholdt’s neck a lot because that was as high as he could reach without effort. Ever since noticing the flustered look and the laboured breathing, his lips often don’t venture higher than the man’s Adam’s apple. Also, the throbbing vein pulsing against his lips drives him wild with desire. Even when they lay down, Bertholdt’s neck isn’t safe from his watering mouth, especially not when he throws his head back in ecstasy and basically presents all that sensitive skin for Reiner to suck, lick and nibble on. Sometimes foreplay is all they want.
