From the product page:
For those nights and days, when you want to be and feel a little special, naughty, and very sexy, these Manties are for you. Once you have them on, it will be “hard” to take them off.
Thanks but no thanks guys. If I want to get a chubby from wearing underwear I’ll put on a super tight leopard print thong like any normal guy.
