Husband wants to watch me take bbc

Husband of 4 years said he wants to watch me take a bbc. I was like hell no at first but after watching some porn and talking to some guys online i think i want to try! We found a sexy stud with a 9.5 inches and thick bbc but im scared it might be too much since im used to my husband who’s 7 inches. Should i give this a go?
