The chastity belt of the 2000s has just appeared in the form of a bra. Japanese scientists have introduced the True Love Tester, a support based on the heart rate of the woman who wears it to determine if she is in love with the guy who stands in front of her or not.
If the woman reaches "the heart rate of love", and only then, the bra can come undone. Without it, it is simply impossible to remove. This amazing lingerie is not yet for sale. It is currently being tested on a small number of couples in Japan.
