This design was inspired by my 81 year old neighbor. Every day "nudist Bob" comes out of his house and onto his deck to soak up the rays. He is usually in his bikini briefs, but sometimes he nude. NOT A PLEASANT SIGHT! But, one thing he and his old friend, who sometimes stops over, I've notice have in common. Their penises are quite thick. It hangs almost straight down, but in the middle of their balls. They both never seem to get an erection. Just a THICK, FAT cock.
I have noticed over the years that older guys, nearly always have thick, fat flaccid cocks.
Well, that's where this design comes from - "nudist Bob". Maybe I should change the cup name to The Nudist Bob Bulge Cup!
