Well, for one, someone could lose their panties and post it on the site, why I don't know. Anyway they list said panties that are then found, perhaps she lost them doing a frantic spur of the moment fuck me session at a park and panties kinda flew away. Perhaps she had lost her virginity and the guy took her panties as a momento but didn't tell her.
Ok, so now, either the woman tells the cop who returns her panties to her the story of how she lost them, or they were actually stolen and she in gratitude let's the cop have her, perhaps while the guy who stole her panties watches from the bushes or what have you. Of course if you go with the telling of the tale, perhaps the cop has her to since her story was so exciting to both of them.
It would have to be a diamond studded pair of panties before I posted their loss on the net.
So there you have your main character. A rich bitch that had a fling in the garden. When she realizes that her diamond studded panties were missing, she goes back to the garden looking for them. They're gone.
She offers a reward for their safe return (before hubby finds out they gone).
And the reward is the opportunity to put them back on her.
lol I did say I didn't know why anyone would post them as stolen, though you know there are people.
Course we can get a tad more beleivable on the reported items that when returned leads to sex. For instance, a woman has a Greta Garbo brassiere from one of her movies, it's a very valuable artifact, that also happens to have an effect on her when she wears it. Not to say Greta Garbo was in any way like this, but this woman when wearing said brassiere turns into a seductive tramp who can't say anything but yes and more to any man she see's. So when the cop's return it to her one of them beign a fan of Greta asks her if she can model it for them, she does perhaps forgetting in the excitement of the return the effect it has on her or just thinks they are really cute guys in uniform and wants to, after putting it on she shows the men her in the brassiere and nothing else and we get a nice group action going.
