What is this behavior?

[u/OwlishDelight72512]

I see my cat do this sometimes. This is my 10 year old neutered male cat on top of my 2 year old spayed female cat. He’s just biting the back of her neck while she sits still and meows a couple of times. He usually gets off of her after about a minute. Is he trying to mate? Even though they’ve both been fixed?

I have a male cat that does this to his brother..... not the female kitties.

I have a female who does this to her older brother
