Holy shit! She wasn’t wearing any panties. She was naked! “Tracy, I don’t think--”“That’s right, Spencer. You don’t think. Or you d...n’t think of anyone except yourself. Now just shut up and let me do this.” She pushed my hand out of the way, positioned my prick and impaled herself on it. I couldn’t believe it. My pecker was up my sister’s snatch.“I don’t understand,” I gasped. This wasn’t an effort to talk Tracy out of what she was doing. It felt too good.“I’m not surprised,” Tracy. She entered her mid teens and still insisted to bathe with him, I watched their love develop, and for a short time let them share a room together, until my daughter debauched herself, again as I watched, it was time to separate them, and I had my excuse.In the morning I confronted her and gave her an alternative, call the police, or send her to bide with her father-in-law, himself a sex offender, that was five years ago, and I hear they are still living together.But now my son is mine, primed. Dripping you dismounted. ‘Hmmm that was nice I think I could go again could you?” you purred into my ear as you rubbed against my flaccid cock. ‘If you continue doing that I don’t see why not.’ Even as I spoke my cock rose and you wrapped it in your hand and pulled and pushed the skin until I was again ready to play our games of love making. This time I did not allow you to be on top but I pushed you to your hands and knees. Ready and hot I thrust deep into your body for I knew that you were. Do you think that was it, my lady slave Shelly? Or will she need more?"Shelly smiled and looked down at her daughter. "I'm sure once from you is enough, Master..." Marie looked up, almost disappointed. They both laughed. "But a few more later in the month won't hurt!" Maire, sensing they were teasing her, resumed her attention to the cock in her mouth.Master nodded his head at Shelly, eyeing her breasts. Wordlessly, she knelt at his side, and held the nearest breast out to his lips. He licked.
