If I had to then it would be whatever celeb/sports star has a a massive Big Black Cock.

Any idea who the might be?

Justin Timberlake because he's had it inside Britney Spears's pussy.

is Peter North considered a celeb? lol

John Stamos

I wouldn't say no to these guys

Alexander Skarsgard
Matthew McConaughey
Charlie Hunnam
Joseph Gordon-Levitt
John Mayer

Denzel Washington.

Brad Pitt
Jeff Goldblum
Jared Leto

He'd be my first choice!

I once saw a picture of Anderson Cooper naked. My gawd what a cock! Check it out if you can.

Emily Maitlis

Dear God Yes. PETER NORTH. I would love to be drowned by one of His massive loads. I imagine sucking on His beautiful Cock, then suddenly and without warning, He explodes in the back of My throat. I choke on the massive volume of Cum, forcing a huge amount to shoot out of My nostrils. I am literally drowning in Peter Norths fresh Cum. He pulls His Cumming Cock out of My Mouth and Shoots several more huge Ropes of Sperm across My face. Coating My entire face like a glazed doughnut. I continue to Lick and Suck His Cock until He is finished. Then I tenderly Lick His Cock and Balls clean. Then I lay back in a Sperm induced overload. His thick hot Sperm coats My Mouth, Throat and Nostrils. As well as My entire face is glazed. So beautiful. Thats My number one fantasy. If I won the lottery, I'd pay to have Him drown Me in His Huge load of Sperm.

Tomasz Schafernacker, Tom Daley, Cristiano Ronaldo, Duncan James.

Preferably all together for a long weekend.

The answer's all in the wording.
Well, let's see ... if I could suck the dick of any celeb there would be no answer - it wouldn't happen. Ever.

However, if I had to - say, at gunpoint or to save the life of my firstborn child?

All things considered, I'd pick Ryan Reynolds.
After all, it's the one that's been inside Scarlett Johanssen AND Blake Lively...

I am very reliably informed that Dion Dublin has a ten inch cock
