Biggest cock she has had?

Biggest that May has taken, that I know of, was probably 11 or 12 inches. Lots of lube to get it in but she doesn't really enjoy super long cocks. I go about 8 inches and am about as long as she can comfortably take.
Though seeing my tiny Asian wife impaled on a foot long cock is fucking exciting!
 
Mine is her biggest unfortunately. Im 6x6 so average length and thick. She cums with deep penetration so I would love to see how much harder a couple more inches in her would make her cum.
