"Okay, spill it, what's up?"Carmen shook her head, "Nothing." Her hair fell around her face, hiding her outbreak of zits. It was blue today, she'd dye... it with cool-aid again, some of her friends had probably talked her into it. I'd liked it better when it was its natural brown, almost the same color as her skin, and halfway down her back; the way it was before she cut it short last year right after the announcement about the swarm.I reached over and brushed it back with my fingers so I could. Sally, looking up at Donny, giggled cutely.Donny didn't know what to make of this. He stood at the glass doors for some time looking at his mother and Sally as they sat in the hot tub, the water up to their necks. His surprise though, was pleasant."Caught?" he asked. "Mom, what are you talking about?"Sally giggled again, ducking her head. But Marilyn noted she wasn't blushing. She felt the pressure of that slim thigh against hers, and knew Sally was feeling excited.Returning the pressure, she. Then she took the head in her mouth and started sucking it a little. She started to make sounds like, "mmmmmm" while pulling up her shirt to take it off. Then she started to slide it a little deeper in her mouth. The stranger on the other side started to moan too. I was so turned on watching her sucking on it I pulled out my own cock and started to stroke it while taking pictures of her sucking it deep. Then she pulled it back a little just to the tip and then forced it deep into her throat all. It was so soft. His cock was full hard now and probably poking her in one butt cheek. Sonja turned around, looking him in the eyes. Oh my god, now she would ask about it, he knew she would and she would tell mum - he had to stop it. He could feel her breath on his face. Even that was turning him on. He had to do something he couldn't let her ruin his life, she had to keep quiet about it, no matter what. He began to sweat. His sister was everything to him and he was her big brother - he had to.
