My Secret Kink

I’m a stay-at-home parent married to my high school sweetheart. Recently, I discovered a new kink during one of our routine check-ins before bed. We both undressed and got into position on the bed, me on top as usual. But then, without warning or prompting from him, I leaned forward and bit down hard on his shoulder. He flinched but didn’t pull away, so I continued biting harder until he let out a sharp gasp of pain mixed with pleasure. Afterwards, we discussed it calmly, consensual kink exploration is healthy in our relationship, even if surprising to both of us. I haven't told him about this yet, though.
