I'll grant that too. Defenseless? Not on your life." I turned her over my knee and paddled her behind. Not very hard, mind you, but hard enough to rai...e an 'OW'. "Do you want your watch or not?" Watch?" she asked as she rubbed her butt ... I offered to rub it for her but she declined..."Since when did it become my watch?" Since just before Tim left. You weren't paying attention" Where did Tim get it?" You ask some extremely difficult questions. I have no idea ... he didn't say." I explained,. I was in the cubical that she normally used so she entered the one I had previously used along with my dried cum stains still visible on the door. She smiled and asked how I was and then said ‘are you trying to avoid me’ A said no, and told her that I had been dicked to do guard duty, in our vehicle compound. She said ‘oh, which is your compound’. I pointed to the hanger and said that one and she looked at it and said okay. As usual we chatted while we showered. I wanted to stay in the shower. When she reached half-way along the bed she took him in her mouth and began a truly fabulous session of playing with his penis in a way he had never experienced before. Her mouth covered only the helmet, and she used her tongue to good effect round the meatus; meanwhile she used her hands, which had also been oiled, one on the stem and the other on his ball-sack. After a short while he was close to his climax and she looked up to see if he wanted her to continue to his completion."That's nice,". She had opened the door to toss her cummy blouse into the hamper. My head snapped up from her undies in alarm at the intrusion. My cock was still hard in my other hand. “Why are you smelling my panties?”Embarrassed, unable to answer, I stood with her panties in one hand and my throbbing cock in the other. Sis stood naked in the doorway. Her eyes never left mine. “Go ahead,” she nudged, “Finish what you started.”I was too fucking hard to argue. My hand started stroking up and down my young cock.
