Ms. Preasha aka “The Head Doctor” Grades Blac Chyna’s Oral Sex Tape Like Mike Mayock at Senior Bowl (Video)

I didn’t think this was a real thing at first, but….

Chyna’s been slammed online since the video with Mechie leaked, with critics calling her effort uninspired and boring. That’s an unfair review though, if you ask Ms. Preasha — aka “The Head Doctor” — and we did. She’s pointing the finger at Mechie for a lack of effort.

Preasha, who presents workshops with her company, Legendary Oral, says good fellatio takes 2 — people that is — and Mechie didn’t hold up his end.

She gave Blac Chyna a C- and Mechie an F.

What a time to be alive.
