When I Hit Puberty:Our house had a hall, 2 bed rooms and a kitchen. I and my sister used to sleep in the small bed room and my mother and father in th... master bed room. I used to sweat a lot so I preferred sleeping on the floor except chilly days. My sister was just the opposite of me. She used to sleep in the bed always. I vaguely remember that my sexual feeling started when I was young but I started masturbating only at the age of 18.The first time I masturbated was in the hands of my sister. Teasing. In bit more. Short strokes. More. Deeper. He was all the way into my cheating vagina. Oh God. "Ohhhhhhhh."He fucked me in missionary. He fucked me in doggie. And I sat on him and he fucked me in cowboy with his hands squeezing my tits. And that's how he came, deep into my continuing orgasms. "Don't stop. Don't stop."And when his cock did get soft and popped out, I stood up beside the sofa. Everything was running down my legs. I ran to the bathroom for a wash cloth, and suddenly started. She cupped his ass in both hands and pulled his cock to her mouth. She took it between her lips, and by holding his ass, moved him back and forth. His cock slipped in and out of her mouth.Tony moaned in pleasure, holding tightly to the bar. He swung his ass, rocking back and forth, driving his cock into his mother’s mouth as she leaned toward it.Judy purred as he fucked at her mouth, her hands cupping his ass, hoping he wouldn’t fall from the bar if he came. His cock felt very hard in her mouth. .. I’m ready for you.” Princess helped him with his aim, giggling in the process.Stu and I did this with Tracy and then with Jennifer, before we had to stop.A loud knock on the door, “Is my sister in there?” Joanie asked.In a moment of silliness, naked Stu opened the door saying, “Yes, she is, do you want to take a number for your turn, Miss Prefontayne?”She walked in quickly, closed the door. She saw her sister, Princess, Jennifer, and Tracy naked. “Why wasn’t I asked to join in?” she said.
