I Just Had To Get F**Ked. That's All. – Cardi B Explains Her Jet Ski Photo with Offset

Turns out Cardi B missing Offset between the sheets is a mutual feeling -- he's still thinking about sex with her too ... and what sounds like a recent romp has him fee(hee!)ling some type of way.

The Migos rapper just posted a video of himself wearing a mask and dancing to Michael Jackson's "The Way You Make Me Feel" on a balcony ... complete with MJ-inspired crotch grabbing and body popping to boot. 

He captioned the post, "P * * * * K N O C K E D M E O F F M Y F E E T B A B Y 9/20 M E R R Y C H R I S T M A S." September 20 is the day they got hitched in a secret ceremony last year. Maybe this is his way of celebrating their 1 year, 3 month-plus anniversary? Or, maybe, he's confirming that they're doing it again. Probably the latter, right?
