I took off slightly faster than a jog to conserve energy, but I heard his footsteps thumping on the pavement really fast, so I quickened my pace. Then...something really weird happened. I heard his footsteps right BEHIND me. So I turned around again and he was right behind me jogging and STILL SMILING!! So I stopped running from seeing no purpose in it and he stopped too.“Get the FUCK AWAY FROM ME.IM NOT THE ONE!” I yelled at him.“Why the FUCK ARE YOU YELLING.” he laughed back.I simply couldn’t. If I got that far, the only advantage for me I could see was what my defensive training for the higher Dan belt had taught me against his type of offense.I had only seen one other competitor with this type of defense, who could match his offense, I don’t know if he was in the right draw to meet the champ, but I really hoped so, that would give me the knowledge I would need to fight him, if he overcame that defensive guy.My next bout was an easy one, I wasn’t how sure he had got as far as he. Denise looked at my sister and then me. She pointed to sis and then me. Then she locked her arms around sis and turned over on her back, pulling her off Samantha and putting her on top. I saw the opportunity and plunged my cock deep within her waiting empty pussy. I slowly stroked in piston fashion. I could feel the other penis rubbing me through the walls that separated us. I grew because of the stimulation to my cock by that touch and the forceful squeeze being placed on me by my sister's. At ten I discovered my dad's obsession with porn, so by then I knew about sex, cock sucking, cum, fucking, and anal.When at eleven and a half, I found my dad's girlfriend's vibrator in a handbag in the wardrobe, washed it clean, and as they say, 'The rest is history'.Whether my hymen was gone by eight or three and a half years later, one thing is certain, by the time I started growing tits, I was hungry for sex, my mind developed at a rate that frightened men, I knew my ass, tits, and cunny,.
