My husband didn’t cum? Dry cumming⁉️

So my husband woke up for a nap and I was rubbing his 🐔. He got super turned on and wanted me to go down on him. I started and after a minute or two it looked like he was orgasming but no cum. I kept going and he seemed like he was having non stop orgasms. Then he told me to stop because it was too much and sensitive and that nobody has been able to do that for him before. Is it possible for him to orgasm without ejaculation? I even made him swear this wasn’t like what women do and pretend they had one. He was like no I had like back to back. I’m confused?

Minus the mustard 😂😂
