He say mommy when humping me

When we was dry humping and I was moving up and down on his lap he keep moaning in my ear, "Mommy". He told me to sit in daddy's lap. I know some men like the whole mommy, daddy pet names but it was weird. Everytime he moved his hard on over my ass he would get all breathless and say mommy, mommy, oh mommy. In a creepy ass voice. The voice was so excited but was very high pitched. To me it sounded like a little kid voice. I've heard women trying to sound like a child while during sex scenes in porn but never the guy.

Are there men who does this??? He's a deep voiced man. And he only does this voice when rubbing his cock on my ass.
