I sat there panting myself, desperately aroused and needing some release of my own.Sean stood up and extended his hand to mine, helping me to my feet....I swayed upon standing, the alcohol catching back up with me after the adrenaline rush of giving Sean head had subsided. He pulled me stumbling into his bedroom, where he tossed me onto the bed. I rolled onto my back, and lay there staring at the ceiling a moment before my gaze was obscured by Sean’s face as he came down over me.“I think a little. She ran her beautiful feet up and down my leg then with her right hand reached over to my jeans and slid her hand inside for the second time today. Her hand flowed through under my undies and round my thighs then she grasped my penis firmly in her hand and started jerking, stroking it up and down inside my shorts. I’m pretty sure it must have been an important phonecall cause it went on for a couple minutes and her mom didn’t notice a thing so I didn’t protest. As soon as the phone call ended. Two people too lost to their incestuous passion.I thrust into her. Hard. My balls cracked into her flesh. My crotch smacked into her. My uniform rustled around me. My badge gleamed in the light, flashing up on my chest. My sister’s snatch gripped me as I pounded her. She lowered her head, letting out just the smallest whimper.I grabbed her ponytail. I gripped her silky hair in a tight grip as I thrust my cock into her incestuous depths. The pleasure surged down my shaft. A taboo rush to do this. Turning to face me, she sat back against the wall. At first she kept her legs together; then, looking to make sure I was watching, she slowly pulled her skirt up until a tuft of hair was showing. Leaning back, she slowly parted her thighs, her skirt riding up even further, until I could see the moisture between her pussy lips glinting in the streetlights overhead. Leaning her head back, she closed her eyes and began playing with her clit.I stroked my cock as I watched from the car -- but before.
