Of course he’d love that spicy chocolate- it makes him all warm and stuff!
As a joke, he decides to kiss you while still having it in his mouth. Slightly scared of the possible taste, you hesitantly give in. Hey, guess it wasn’t that bad? His mouth is warm and the melted treat leaks inside yours. It’s tingly. Sparks of warmth cover your tongue in sweetness and fiery sensation.
It’d be like eating Pop Rocks. But literally hotter and emotionally more fulfilling.
