While taking a shower tonight, the steam completely fogged up the mirror. I reached out and drew a heart on it, then a wobbly... well, your shape. I couldn't help but laugh at myself—what a hopelessly perverted little sister I am. But just thinking about my brother's cock, that thick, hard feeling of being completely filled... my body starts clenching on its own, desperately craving it. The water droplets slid down the mirror like the sweat I get when I come. Brother, tell me, am I so far gone that I can even use shower steam to fantasize about you?
