The young guys will not remember her, but she was (at least for me) the first natural mega-bust star I recall. Her heyday was mid to late '80's I think.
Devon was a legit 36DDD; before all of the exaggerated bust sizes. She had full, terrific hangers that were capped by perfectly symmetrical and proportional areolae that were about three inches in diameter.
She made some videos in the Bahamas; all softcore. She starred with Lisa Phillips in some and the themes of the videos were Devon walking nude on the beach, Devon trying on bras, Devon exercising by the pool, etc.
I am aware now of a recent video that has popped up of a sort of behind the scenes where Devon is lying on the bed and I can only presume it's her boyfriend, but he's lying mostly on her holding and sucking her huge natural tits. Absolutely nothing hardcore about it, it's almost like a candid camera shot. I think it was probably taken after one of her videos was finished and I would think her boyfriend was standing there watching during the filming and when it was over, the temptation was too great for him not to quick jump over and get in a quick suck of her big tits.
Anyway--nice to come across something new from one of the all time greats and the girl who opened my eyes to the beauty of huge all-natural breasts on a slim girl!
