If you have a sweet ass, then you have a responsibility to show it off, especially on Valentine's Day. Fellas, give this hilarious card in your new thong, and we guarantee you'll get a reaction from your Valentine. What type of reaction? We can't really say, but a reaction nonetheless. It doesn't matter if your thongs are cotton, silk, polka dots or lace. As long as they show off that perfect backside, then your Valentine is sure to gasp in appreciation, fear or disgust. One of the three.
