He replied NO to all three…as I expected. I said “you have to keep this our secret” and his head nodded as quick as could be. I pulled my cock...out of his sister’s mouth, gave her a sloppy kiss…and said “you will now suck your brother’s cock”. A simple nod of defeat from her, a quick turn to her left, and in one gulp she devoured his 3 inch dick. Fuck this was hot watching this…I watched her suck his cock for about 3 minutes…and he was loving it, and I think she was too. I started thinking. Scalding heat radiated through her skirt. “Fuck, that hurts.”“I'm not surprised. You got it bad,” Nicole said.“He was hard on me today.” She was proud to admit it. She'd be sore for several days, but the extended period of pain would pacify her conscience. Closing the door to her studio apartment, Alexa rubbed her butt. All the way home, it was all she'd wanted to do.The train journey had been like sitting on a bonfire. Held tight in thin panties, the heat from her painful butt couldn't escape. What happened next seemed to happen in slow motion, Connor stopped very suddenly in front of me, turning to face me, his arm with the HCl swinging round as he turned, some spilling out of the top, he noticed the spilling acid and made the exact wrong split second decision and let go of the beaker which flew through the air right at me. The acid splashed all over my white blouse. Connor stood frozen in front of me a horrified look on his face as if he expected me to start corroding right in. I picked up Consa to break the situation. "Show me how you attack and I will show you an attack my father taught me."Consa was not sure what to do. I stayed on my butt on the floor. The boy thought for a minute then through a feint before launching his own attack. I made a flurry or moves barely deflecting his blows. He was able to do two more before I wrestled him to the ground with a lot of grunting on my part. Once he was on the floor his garment came apart and I blew a raspberry on his.
