Step sisters knickers SeXStoRY

One weekend i came home to visit my mums house, and by chance my stepdads daughter was staying over too. I dont get to see my step-s****r very often but have fantasized about her before and have always thought about her knickers!! She had a habit of leaning forward and showing her knicker line off!! She was 20 back then, slightly chubby with pale skin, and has straight red hair and a freckly face. She had driven the long road up to our house from london so that night she went straight to bed. The next morning we got up and the f****y decided to go out to a park to see some a****l show, but i saw the blatant opportunity!! I told my mum i didnt feel well and was going to stay in. They all loaded the car up, and i heard the doors slamming and the car drive off. BINGO!! I left my room and went to the guest room. Her bag was sat in the corner neatly zipped up, not a problem becaise i remembered what it looked like. I opened the main compartment and immediately smelt her perfume and saw her clothes folded, but no dirty stuff!! Next i tried a side zip compartment and hit the jackpot. inside i saw a purple thong with the words "sweet girl" printed on and her socks from the night before. Carefully remembering how they were and how they looked i pulled them out and openend them up. I thought about her curvy arse sat in her car for the three hour drive, these were going to be good!! They had a white streak, still damp on the gusset and i could smell her pussy so well, the thong smelt strongly of asshole too!! By now i was stroking my cock with her damp socks, holding her pussy to my nose. Just before i came i emptied my lungs and breathed her smell in as i filled her socks with cum. Shed never know.
