Hmm, it's sort of semi-erotic in the way that a lot of the weird stuff you see on on sites like Wish, which may or may not be sex gear, is. I mean, the model is attractive but they're fairly normal looking PJs otherwise. Could be hatch for bumming/doggy style of course but they seem so utilitarian otherwise. Maybe that's the kink, bumming a woman while she's fully dressed in workaday winter pyjamas.
