Challenge accepted.

Yeah, my whole thing with it was, it would be cool if it were a Sci-Fi type door, with a hole meant for a cock to fuck it. So think of like a Flesh-Light type deal, or some sort of cock milking thing. The cock would have to orgasm in it once or twice and the High-Tech door would be able to collect the cum and determine if it was enough for the door to open. And then, and only then would the door open. I think there could also be some system implemented where the door can determine if a cock actually did just ejaculate fresh cum into the door, or if someone used a syringe or something to pump some cum in and cheat.

I also do like the idea of there being another person on the other side of that door who wants to eat fresh cock and gulp down some cock milk. And if they are not satisfied, then you're not getting through.

Im going to go get this commisioned now

PLEASE SHOW ME WHEN YOU'RE DONE LOL

Let's seriously think about how the door would work,the idea I had, was that there would be no doorknob, using the cum quota idea, there would be some form of contanier, that when heavy enough, would push down a board that would otherwise be level, upon which the board would be pushing up on an upwards facing shutter door lock. And just like that, you have your own door that you not only CAN fuck, but NEED to fuck.
Honestly, I think I just made a Saw trap.

I would try to come up with an idea of how the sci-fi door would work but I know nothing when it comes to electronics, but if someone does know, then do what I did, and (try to) explain how it would work.

Ill post it and put a link here when i do XD

What have you been smoking

Nothing actually

Guess what I found!

Seems to be like a treasure chest oO

Maybe if the door had a slick cock-identifying mouth that had a button at the other end that you had to hit with your tip, then that would be interesting. And if it doesn't identify you, it would fuck your cock real tight you wouldn't be able to pull it out until the owner or police arrives. Just a thought.

I know for a fact there is a comic about this somewhere - I've seen it.

A girl is the lock and you have to fuck her right for her to let you through.

Thay would be a good idea for a kinky D&D campaign where the chest is a mimic and to open it you have to either: A: stick your dick in the keyhole and fuck it till you cum or B: ad a female the lock has a dildo that pops out and you have to let it fuck you

Maybe this is what you saw?

I have had a very similar but very different idea. With my idea you didn't just open doors, it was more like a dungeon where you would solve puzzles by putting your cock in the fleshlight like holes in the wall and the puzzles would require you to keep your cock in for a set amount of time. The fleshlight like hole would automatically stroke, vibrate, rotate, etc... while you are in it. As you go it would get harder and harder because your required time would increase, the texture inside the holes would change, and the stroke/vibrate/rotate speed would increase. The plan was to have a group of guys trying to get out of the dungeon. If you cum it would be game over. XD
There is still a lot more to it, but that's the basics of it.
