The island’s The New Paper recently reported that those with a fetish for soiled underwear can get post-sex panties at SGD80 (RM240) a pair, via an online auction.

For the right price, buyers can even get the undergarments hand-delivered by the girls who had worn them.

According to the report, websites offering the items have of late, appeared on social media with pictures of the underwear, as well as the wearers, in compromising poses.

Even students are making money out of the craze, with an 18-year-old girl “fresh out of junior college”, offering to sell her panties for a starting price of SGD20 (RM60).

One of the posts said the undergarments were “guaranteed to satisfy your school-girl fetishes and much more”.

The price reportedly goes up based on the time the underwear is worn, and whether sex acts were performed while wearing them.

One seller, who put up her panties, which she claimed to have worn for 12 hours, for sale for SGD80, has also recruited “like-minded” girls to sell their panties as well, said the report.

When a journalist from the paper posed as a girl interested in joining the venture, he (which the girl had assumed as a she) was told to wear panties and perform sex acts in them, which should be recorded on video, to boost the price further.

The girl claimed a pair of panties can be sold for more than SGD200 (RM600) on average, and can be sold out within a week.

However, the girl stopped corresponding with the journalist and took down her page after he revealed his identity to her.
