(M4apf) when your girlfriend turns out to be a dullahan

I think the titles says most of it. But if I can give the full idea. It might be a bit more wholesome, but I am looking to do an rp with someone willing to play the mythic creature that can remove their head. I would like to make it a bit funny, like random times she ends up throwing her head, or even hiding her true nature but losing her head in these times. And if we are able to, we could explore other kinks. Maybe pregnancy or weight gain added in. Just send a message if interested.
