Stepdaughter Moans Too Sexy

My wife was out late with girlfriends and her innocent ponyhaired daughter was looking so cute in a cropped t-shirt revealing her fit tummy and barely covering her smallish but firm tits. My stepdaughter was obviously not wearing a bra and the bottom of her tight ass cheeks would occasionaly peek out the bottom of her too short pajama shorts which were tight and thin enough you knew she was wearing a g-string. Good thing she was wearing panties I thought as I fought the idea that my stepdaughter looked a bit slutty and so fuckable. After turning away from her several times to keep from staring and to hide the tent in my pajamas, I decided it best to retire to my room to take care of my aching cock. Saying good night my daughter gave a little kiss to my forehead that made my pecker throb. Once in my room, I took it slow while thinking my stepdaughter is a sex goddes. Our rooms are quite close, so I was trying to be as quite as I could until I hear a little moan from her room, which was quite normal. Knowing the wife would not be home for awhile I was emboldened and curious enough to go to my daughters door to get a better listen. To my surprise and delight, my daughters door was not completely closed, I barely pushed the door open a bit more to get a better peek. I could not resist as my cock throbbed and she was purring enough she would not hear. My beauties eyes were closed so I felt invited to admire and enjoy forbidden art. Maybe she was thinking of daddy as layed uncovered and naked on her bed. Sadly her panties were on and covering her pussy. Mesmerized by her georgeous tits, tight tummy, soft moans, and fingers roaming under her panties, my desire to see that tight teenage pussy grew so much that I pulled my shorts down and began to stroke while imagining her fingers going in and out while making wet sounds. Then her hips started moving and she slid a red g-string off all while lying. Now staring at her shaved pussy with full lips and budding clit, I so wanted to fuck my stepdaughter. This was not the first time but it was the strongest urge yet. But I knew I had to walk away, but could not. Instead I stood and watched while edging my hungry dick. I had never before witnessed something so hot and sexy. My heart was pounding and I was trying to remain silent. Lust overcame me and I was about to walk into her room when I snapped knowing I was about to shoot my wad. I whisked to my bedroom where I had one of my best orgasms ever. This happened about six months ago and I want to masturbate everytime I recall. I only wish I could have lasted long enough to see my daughter come. My life will never be the same with the realization that I could be fucking my too sexy stepdaughter. The sooner, the better but the danger of getting caught stops me. If my daughter does not stop teasing, then she is to blame.
