Help me find the “first time in winterclothes” anime

I remember once watching a scene of what I presumed was a romance, comedy anime, where there is two characters (guy and girl) and they appeared to be getting ready for their first time. They were wearing winter clothes (I think it was so the girl didn’t feel exposed). And they were both very nervous. The girl was especially afraid it was gonna hurt and screamed before he even put it in her.
I think they both had black hair, but I’m not sure.

Does this ring a bell for anyone? For the life of me I cannot find it.
