I was as hard as a rock, how could I not be with this hot piece of ass straddling me telling me she was going to fuck my brains out. She began strokin... me and I reached my hands up under her skirt feeling for her pussy. I found it (right where it should be) and ran my fingers over her slit, which was slippery with her wetness. Just before I was about to sink a finger into her she disappeared off my lap and reappeared on her knees before me.“Take off your pants,” she ordered and I complied.I sat. I saw Sophia approach the doorway and she froze.I walked up behind her and saw Zak completely nude sitting on the edge of the desk. His dick was filling erect with the beautiful head pointing up.

I guess you look a little surprised to walk into this. Well, I had planned this. Then he’s naked, too, and he has a pretty big cock sticking up into the air. She reaches out and wraps her hand around his cock and steps up to him and they kiss and she tells him what a great cock he has and kneels down and gets her face to it. She kisses his cock and licks back and forth on it then gets her lips around the head and slowly seems to swallow it. ‘Can you rewind that and show it again?’ Rochelle asks. I can, so I do. We watch it again and then the girl goes on to slide her head. That was when I found out that she was virtually blind in one eye and could not see clearly beyond about 15 feet with the other eye. After a strong argument, I got her to let Replicator examine her eyes. It turned out that her problem was with cataracts. Replicator said that he could fix the problem in one day if she would cooperate. She agreed after seeing what was being done with Sam, so Replicator operated on both eyes in one day.The artificial lenses that were installed in Sarah’s eyes made.
