Hi, thanks for link, but no he has not inspired me, haven't seen that hole
Mine is not flat. More shaped like a semicircle. Mine is designed to allow the person on the sucker side to rig mouth as an open pussy and the guy on the outside to fuck that "pussy" in a comfortable way. A flat wall makes it difficult and the fucking is half-baked and not so easy for the fucker. I have had guys who seem to forget what kind of hole they are actually fucking through that slot and fall into "authentic vaginal thrusting" at the end when they take themselves to an orgasm inside that "vagina". I have had to train my ability to stay in place when the going gets rough LOL. Maybe you mean inspired by LED stripes. Well, no, I just found stripes at Bauhaus and glued them there
