I had this happen to me many years ago. I was 20 years old and my girlfriend now wife barely 17 She met a older married couple at work and we became close friends quickly. Gary was 27 and Juanita was 25. After a couple months we moved in with them and was smoking weed and snorting coke daily. A few weeks after moving in we all decided to party in their huge bedroom and watch porn. Next thing you know we were having sex with our wives on their king size water bed. It was awesome knowing they were 6″ away watching us and us watching them. We were all off the next day and we remained nude all day. We all agreed that was awesome and Gary asked me if we would consider sharing their bed permanently. I told him I wanted too but needed to discuss it with Brenda. He informed me it was the girls idea. So we moved in our new shared bed ASAP. That night we started sex up and after we all got our rocks off we moved back in the living room for shots of 151 Rum, weed and a hit of acid. This was 1978. We munched a little and was now tripping good. Me and Gary hopped in bed waiting for the girls. They surprised us when they swapped us. I was amazed watching Brenda sucking his dick and fucking him. Juanita was very experienced and couldn't get enough. I have an 8+” dick and a 6″ girth. Gary was at least 9″ but 7 1/2′” girth. It was massive. Brenda had to struggle the 1st few times sucking and fucking him. Once she was able to do so she loved it. The next day the girls had to be at work by noon. Me and Gary stayed up and did some yard work while they slept. They got up and they took a bubble bath together. We realized they were having fun washing each other. When they got out I asked Brenda about swapping and her new found love of pussy. She told me Juanita wants to swap again tonight. She also told me they were going to give us a show tonight. I got hard thinking about it. She said you always said you want this. Do you still? I couldn't say yes quick enough. She said you've licked your own cum off me and out of my pussy many times. We talked and I want you to lick Gary's cum out of my pussy tonight. She said Gary has already agreed to do the same. I said macho man Gary. I can't imagine that. She said he is excited to lick Juanita clean. I reluctantly agreed. She's right I've licked my own a 100 times before. I don't mind the taste. If he will I will. They left for work and we both showered and still naked climbed on bed to catch a little shut eye while they were at work. We lay there on top of the covers when Gary asked me if Brenda mentioned clean up. I told him I agreed as long as he did too. He said Ted, Juanita has been the perfect wife. She's wanted me to do something like that or more for years. Your the 1st guy I feel comfortable doing something like this with. I told him I felt the same way. We both had full erections talking about it. He faced me and said let's Jack off. Between me and you, ok. I agreed and we rolled close enough that our dicks were rubbing one another. A few minutes later he said he was about to cum. He begged to cum on my dick and I agreed to let him. He exploded over and over. My dick and balls were coated, my hand was coated and he even shot a couple of streams on my stomach and chest. He asked me to cum on him. I said I was ready and he slid down and I gave him a facial and some in his mouth. He then pulled cum from his eyelids and said that was awesome wasn't it? I had to admit it was kind of exciting. He was licking his fingers swallowing my cum and I had a hand full of his to lick off. I said you know yours taste like mine and I swallow mine almost everyday. He agreed. We both cleaned up and laid back down. He told me he couldn't wait for tonight and I agreed. I was drifting off when I realized he was now sucking my rock hard cock. I pretended to be sleeping for awhile. It was impossible and I put my hand on his head and told him he better fucking swallow every drop. He looked up and said just let it loose Ted. I've wanted to suck your dick for a couple of months now. He went back to work and he was good. I warned him and I began to cum in waves filling him up. He cleaned every drop. He slid back up against me and I couldn't miss that big hard fat cock of his against my belly. I told him I'd never given a blow job before. He said he just did what he likes. I was able to get my mouth around it easier than Brenda did. I was soon getting 6 or more inches down. He started face fucking me and let me know it was go time. He cum over and over. He filled my mouth so I let him cum all over my face. Finally I swallowed and began cleaning and draining his monster. We fell asleep for a few hours and got up and fixed dinner. I decided since the girls were not due home for a few hours I would want to suck him again. This time we got in a 69 and cum at the same time. When the girls cum home we served them dinner. We surprised them while they were eating. We sat by them and started giving each other a hand job. Then Gary got on his knees and sucked my cock finishing u swallowing. They hooted and cheered for more. They were amazed as I swallowed almost to his balls. When he cum he pulled out of my mouth and shot my face and then finished back in my mouth. Later the girls put on a sexy show as promised. Long but absolutely pure factual story.
