My daughter stood in the door to my office and tossed off her shirt, no bra. Ignoring my surprise, she slipped off her shorts, revealing a black G-string that covered her trimmed pubic patch perfectly. Her fingers slipped under the thin waist string and slid the tiny panty off, hooking it with her toe and leaving it on the pile. "Okay." She said and walked out to the pool. My c**k was hard. I heard the slider open, and I had that black G-string in my hand before the door closed. I stood back from the window, my shorts and briefs at my ankles. My daughter's warm underwear at my nose, my hand stroking my c**k as I watched her perfect ass appear and disappear in the water. She smelled wonderful, different from my other daughter. I keep trying to get Deb's panties but haven't yet. My guilt
