As I was flustered and looking around, my friend's younger sister smirked and lifted her skirt...and there was my smartphone! And I could see her panties too! What the hell is going on? As I was confused, the temptation escalated. Though I thought it was bad to be aroused by my friend's sister, I couldn't help but give in to the temptation. My fully erect self finally crossed the line...
