First time blowjob

Hi, after many years of marriage my wife loved me licking her pussy but started to give less and bj's. Ower sex life was good Barrington fact I received maybe 1 bj every 3 months. I licked her2 or 3x a week. Then gradually after we fucked she started to push my head lower. First few times she stopped with my head on her belly. Then 1 day after a really nice love making, I was resting my head as usual on her belly, she asked me with gentle pushes , she wanted me to lick her pussy. I slid down and started to lick her clit. She was getting really turned on and asked me to lick her whole pussy like I always do. This time it wasn't just her juice. Mine was inside her as well. I thought , ok so I went for it. After a few full licks it wasn't to bad. I was at the bottom starting up and she pushed her belly and tightened her pussy and my whole load shot out directly into my mouth and onto my tongue . I didn't know what to do other than to swallow. I did and it was good. After doing that a few times she asked me if I had ever thought about what it was like to get cum in your mouth directly from the source? I said no, I've never thought of it. She confessed she had always wanted to see a guy give a bj to the finish! I said if that was what she wanted I would try but don't know where to even look for the doner. A few days later she said she found a guy but he was extremely straight. She told him she only wanted to give him a bj, nothing else! She also told him she wanted him to be tied up and blindfolded! He agreed, the next day was selected. He arrived, she took him into the bedroom and tied and blindfolded, then i entered the room. She had me unzip and remove his pants and underwear. His cock started to spring to life. As I started to suck she was getting dripping wet. After about 20 minutes he said he forgot to tell her he couldn't cum just by a bj! She asked him what he needed? He said he needed to fuck! She looked at me and shook her head no way, then she got a big smile and tapped my ass!! I shook my head no! She nodded YES. She reached into the nightstand and remove a bottle of lube. I had only been wearing a housecoat. She poured some on my Crack and her fingers and inserted 2. That was an ouch moment. She started to slide them in and out. All the while im still sucking cock. Then she added a 3rd, another ouch moment. After a few minutes she used a lube injector and shot a bunch up my ass. Then tapped my ass and pointed at his cock! I straddle him in a reverse cowgirl and slowly started to lower myself onto his 8 inches. The pain wasn't bad at all. As I was about half way down his length I stopped for a breather, that's when he arched his hips and drove the rest in, WOW I felt really full. After a few seconds I started sliding up and down his length. When I hit the bottom I started to clinch my bum muscles as I went up and relaxe on the way down. Then on the way up he started to pound into me so I just stopped and let him go at it. After about 15 minutes he grunted and said he was going to cum. I sat down hard and felt him shooting lots deep inside me. When he was finished I started to slide up and down again hoping to keep him hard for another round. Unfortunately he started to go soft. Wife and I left room quietly, wife brought in a facecloth. Made me clean him up then a few more sucks to see if he would get hard again, no luck. I left, wife untied him and remove the blindfold. I could here their conversation. He said Wow that was great, he has never cum so hard, said thought he was never going to stop. He then said she has a really talented pussy, her husband was a lucky guy. Since then we have had many encounters with men. She loves watching me get fucked and giving blow jobs. She is looking for the 10+inch guy now
