She pulled the string out of my crack put a lil lube on her finger and started to slowly work her digit into my ass, when she did a drop of precum cam... out of my cock. Saw that and leaned down and licked it with her tongue and said wow I guess you do like that as she worked in a secong finger. I looked back at her and said just wait until you fuck me with that dildo. She asked me what was going to happen and I said you'll see so she grabbed the dildo put some lube on it. She worked the head of. So I was having fun flirting a bit. Though I am 58 I am not dead and I always enjoyed talking with woman. We had cocktails and some food before dinner then after many went to the bar and I sat at the bar. This beautiful woman in a skintight black dress came up to the bar by me to order a drink. I said hello and offered to buy it for her. She said no but thanked me. She was a bit tipsy I thought so when she leaned a bit to far I caught her getting my hands around her waist. She smelled great too. She went off to have an evening shower as soon as I entered the house. I sat down on her bed and started thinking about the science project which we had completed just a couple of hours ago. Suddenly I felt an urge to go to the washroom and so I went to the one attached to the bedroom (there were two washrooms in the house, one was the main washroom and the other was a smaller one attached to the bedroom).It was then that my luck changed. When I came out of the washroom, I was totally dazed at. As I walked to it, another outburst echoed to me. "I won't thrash you this time whore, but as punishment for disobeying I will use your body to please me! You are not to cum, whore. Do you understand me?!" I peered into the room and I met with a sight that left me breathless. Kneeling on the floor was a woman not much older than me. She was stripped naked, bound by ropes, and had a gag in her mouth. She looked so defenceless and yet she looked excited by the man's actions. The man slapped her.
