In my early 20s I had a relationship with a couple much much older than me. The husband was early 70s and the wife was mid to late 60s.. I had meet them while working as a delivery driver. The first sexual encounter I had went to their home where we talked and it wa brought up that he had a hard time preforming and couldn't stay hard and asked if I world have sex with his wife. At first I didn't know what to really say. We kept talking about it it came out that he is slightly attracted to younger men. The conversation continued and I finally agreed. The wife stood up and removed her shirt showing a sexy Victoria Secret bra. She than took her panties showing the matching panties. Now I've had a panty fetish for a long time and with her body for her age got me hard. She has a great body very wide hips and a very big behind. She walked to the chair and reached to undo my pants. She got to her knees and started rubbing my hard dick. The moment she put her mouth on it I knew this was going to be great. Her husband sat directly behind her across the room. I could only imagine at the time the view he had. I would soon find out as she got up and walked to get husband and did the same to him. Her ass was so big and round. She would suck her husband's limp cock and she would ask how he liked looking at my her cock. We all got up and she lead me to the bedroom. She had me sit in the edge of the bed. She started to take her panties off and told her to keep them on. She laid down spread her legs and told me to suck her pussy but to keep my ass to where her husband could see. I did just that. Her pussy tested amazing. My dick was so hard eating her pussy and knowing someone was looking as my ass. I crawled up to her and told her to hold her panties and I slid into her. It was great I fucked her and fucked finally I had to have that ass and forced her over and yanked her panties down exposing her ass. I caught a glimpse of her husband, he was jacking off fully erect. Her ass was shaking, I spread her ass to look at her asshole while I fucked her. She was moaning louder and "I'm going to cum keep fucking me" her husband made his way to the bed and ejected all over her fat and back. Most of the cum ran down her ass crack covering her beautiful asshole and lubing my cock. I couldn't believe the amount of cum he sprayed. I kept fucking i had gotten so horny watching him cum and the way her ass looked with cum on it. It took me another 10 minutes to cum because it was so wet. The smell of cum was strong that I finally let go and finished her pussy. It was an amazing first time. This went on for months. Sharing each other.
