The following weekend, they invited us over to dinner, where the four of us were alone in the house. After giving Carol a couple glasses of wine, they...told us that they wanted her to be their sex slave again that evening. After giving me a questioning look, and receiving an affirmative nod from me, she agreed. They told her to strip, and stay naked throughout dinner. Carol was embarrassed to be nude, while the rest of us were dressed, but she was also turned on by the attention -- every time. Her willingness to please soon had her on her knees and she tried her level best to bluff her way through, sucking his cock, which felt very big in her mouth, as well as long. Despite her anxiety, she was enjoying what she was doing, how good he tasted and how he felt in her hand and mouth.She continued to wing it until he stopped her as they fell onto his bed and he kissed her again before moving south to give her a good session of oral in return while continuing to finger her pussy. He moved. A half hour later, Nikki came out asking if she was OK? CC told her that she was fine, maybe even better since Alton had tried getting his cock and balls into her before, but couldn't. She added that her nipples were tinder because they we're use to the attention they gave them, but she loved it! Alton came home, walking into CC breast feeding both girls with their heads in her lap. The girls started getting up he said, “don't move! I love the site”. He sat, watched and chatted with CC another. She gets me a pair of her heels and tells me to put them on, tells me to get used to them for Daddy arriving.I put them on and go downstairs, leaving Nina to finish getting ready; I pour myself a glass of red wine, to try and get rid of the nerves.I am onto my second glass of wine when I hear a knock at the door, I go to answer the door, I see Daddy staring back at me, he says Nina has done a great job you look so sexy Stephanie, he walks in and closes the door behind him, he puts his hand on.
