After lunch we decided to give it a try and see if it could go further then just sex. I was more than willing to give it a try and so was Cassandra. W...e talked about the sex too, and decided that it was the reason that Cassandra was interested in giving it a shot in the first place. Well, that was all it took for me to get an instant hard-on and start to yearn for her again. We went back to her car and drove back to our apartment building. On the way back, I got daring and put my hand on her. "Please don't tell Miss Marlene. She'll make me leave and I have no where else to go," he pleaded in his small voice. The tears were flowing, he was genuinely scared. My heart almost broke by how helpless he seemed. I pulled him close to me, holding him, wanting to make it okay for him. Our cheeks were pressed together, mingling his drying cum and his wet tears. "There, there," I said, "everything will be alright." Looking down I saw his cock, slackining but still impressive. Then it hit. "Ummmm, Saber! OH, G-G-GAAAWWDD, FUCK KATHY!" she cried as she felt her nipples tighten. The sheep dog moved back a few inches as if he were hesitating."What are you waiting for? Shit, fuck me!" Kathy moaned as she banged her ass angrily up and down on the groaning couch. The dog barked playfully, then jumped off the couch and started running around the room."Get up here! Ohhh, get up h-h-here!" Kathy shrieked as she felt her pussy sucking and rubbing and throbbing with each stroke she gave. “That’ll save you having to do the washing today won’t it?”“Sammie! You’re my daughter! What the fuck are you doing?”“Oh come on, Dad,” she said. “Surely you know. I’ve just sucked you off.”“But….But…You’re my daughter!” I said again.“You said that already,” She grinned. “Try something different like ‘Hey, Sammie, that was a great blow-job’ Something like that.”We stared at each other and she finally wriggled and cuddled in to me. I put my arm around her.“I know you needed that,” she.
