A young couple (18+) who have been dating for a couple of months are finally ready to have sex for the first time, She is still a virgin.
There is just one issue, she has a chastity belt that is locked and requires 4 digits to unlock.

The four digits are held by her family to be exact, her female cousin, her aunt, her older sister and her mother. Now the guy has to prove to each one that he can satisfy a woman from their family sexually to receive each digit. Basically he has to have sex with each one of them, giving into the kinks that apparently run in the family. Will he succeed in pleasuring the four women and after that is he prepared to give his girlfriend the best cherry popping of the century?

Also sort of thinking that this would also work with all genders swapped and a cockcage in stead of a chastity belt, but that immediately feels a lot more going towards CNC for me, (Even though that shouldn't really matter.) so I don't know about that...

I like the idea! (y)

I suppose my only question is what about any men? Are any/all of those four in a committed relationship? Unless its a different culture, that could be sticky.
 
Four decimal digits is only 10,000 combinations. If you check 1 per second, you can guaranteed solve it in less than three hours. On average, it would take something like two hours and 45 minutes.

Make it four letters, and use dials that have all 26 modern Roman letters, and it's more like 125 hours. Add another dial and it's 26 times more, or something reasonably close to four months (24 hours a day) to just methodically try every single possibility (meaning that on average you'd finish in half that time).

I was just thinking about a scene where he's told he has to prove he can pleasure the other women, and he goes, "Nah, give me a few hours."

What you could do is make it biometric. Each one has to put their thumb on the lock to undo it. You could then add a voyeuristic element where they watch, just to make sure he's doing her right. Which immediately turned into a comedy scene where they're critiquing him over each other.

"No, do the thing with the clit, like you did with me."
"No, no, play with her pucker, that'll really get her going."
"God, grandma, you're so gross. Obviously, nibble a nipple."

Things like this is why I'm only allowed to write non-human smut.

I’ve brute forced a 4 digit lock at least twice and probably three times, two of those for shits and giggles. If sex was the reward I’d do it a few times a week.
 
Easiest way to do it is make it a fantasy story (could be a modern setting if that helps). The chastity belt is a spell. If you look down there she doesn’t have a physical belt: she just has a little tattoo with 4 markings on it.

Try and rub her over her clothes, you get a zap. Try and fuck her…well, your tip or fingers will start warming up the closer they get to her slit, by the time you actually touch her you will literally get burned.

Each family member has a spell that will remove a mark: get rid of all 4 and it’s safe.

Adds a nice bit of progression: she can see MC’s efforts. OOH! Maybe it’s a pentagram: could either allow for a fifth person or it shows how the best anyone has done before is to get one mark taken care of

Depends on what atmosphere you want. The thing could have four keyholes, and every hasp needs to be opened to get the belt off.

Also, in this universe angle grinders and files don't exist, I assume.
 
"This is The Lock Picking Lawyer, and what I've got for you today is an eager virgin wearing a chastity belt secured with a four disk combination padlock. Decoding these is a relatively simple matter with a tool like the notched decoder..."

sorry, couldn't resist lol
 
Whole cottage industry around removing chastity belts for virgins is not a bad idea, just saying. Mild derailment, but we're still talking locks, so maybe not so much.

So, village has a dragon problem. They're finnicky fuckers, won't touch any sullied females, so as soon as they come of age, all the women who are deemed fit for dragon bait are locked with chastity devices. So, one woman in town, or a neighboring town, offers a service to help remove chastity belts. Started by doing a favor for a family friend, then realized she could make money off of this and soon, more and more virgins sneak off to seek her help.

Problem is, eventually they run out of virgins, and the dragons come back, demanding their normal course of virgins...

It's an 16 digit lock and each member holds 4 numbers. Crisis averted.
 
I used that idea but for a giant rather than a dragon.
They took the virgins to the hills and gave them the fuck of a lifetime? The villagers misunderstood and think it's a sacrifice. In reality the giants are erotic altruists that look with pity on the virgins, taking them home for the best sex this world can hope for?

The Giant's Bride: Some cocks really are just too big...

It's really less complicated than that. They have human retainers (you even try to open a treasure chest with dragon claws? Didn't think so.) Their humans just get so lonely and they feel bad for them.
