Very nice. Your thong panties look totally appropriate on you.
I suggest your woman keep you in feminine panties on an every-day basis, including pink rhumba panties with frills across the back. I also suggest an array of more-feminine colors — bright red, light blue and light yellow, for instance, in addition to pink, all with frilly ruffles. You might point out that if she were to do this, it would reduce the chances of you lowering your pants for another woman.
