It was going to be a long semester if this man was going to be a frequent model for the class. A part of her desperately wished that false but a more ...revalent sexual part of her hoped direly it was true. All she could do was try to focus on actual drawing on her paper rather than slipping into daydreams of her drawing shapes on his chest with the tip of her tongue. His smile broadened and something about it told her she didn't do well in hiding her lust. Sheepishly she hid behind the expanse. What I saw nearly made me fall backwards into it with shock… There was my sweet wife Ana, on her knees like a total slut, sucking the biggest black cock I had ever seen… Tyrone had one of his hands on her left shoulder and the other at the back of her head as she bobbed up and down on what must have been at least an eleven inches dark pole. Instead of getting angry, I found myself getting enormously turned on. This was not the first time I could see Ana with a black man and all I could think. " Oh? Like what?" She turned back.Lauren stammered. "Oh, anything." What book is that?" I asked.She looked down at it. "The Enneads, by Plotinus. It's a boring old Greek thing." I know what it is." I wondered, was it a translation, or did she read Greek?We all looked at each other. I tried to think of a way to keep her around."We could get coffee and discuss Plotinus," I said.She pinched her face. "I think I'd rather -- uh ... well ... I can't think of anything more boring. That's it! That. I think they even grabbed each other's breasts a bit, playfully. We lazed a bit in the sun on the blanket, me in the middle now. I dozed a bit but was awakened by someone gently teasing my cock. I looked down to see Mari tracing her fingers along the length of me. "Yes, it is." Mom whispered."Yes, what is?" I asked. "We both think your cock is gorgeous." Mari admitted. "Look how big you are. Very handsome." Et Mama aussi." She said as she reached across and groped and handful of Mom's full.
