Her sister, Riya, is a slender beauty with long limbs, but a little airheaded. One day, I caught her in a panty flash while she was napping, and even though I knew I shouldn't, I couldn't help but stare. When she woke up, she whispered with a smile, "Do you like looking at panties?" From the next day, taking advantage of her being away, I was seduced for three days straight.
