First time

Hi. Im 60. Many years ago my then wife was looking for excitement. We had been married for 20 years. After we had sex she started gently pushing my head down to lick her pussy. I thought ok. It came from me mixed inside her. . After a bit it was no problem doing the cleanup as I had cum in her mouth many times. So the taste didn't bother me. After a while when I came home, she was always horny and wanted me now. Then came the cleanup. I noticed a slight change in the taste. Never put to much to it, thought maybe to much coffee or something. Then 1 day she wanted me to lick her before we had done anything, ok I did what she wanted. Her pussy seemed extremely wet, ok she is just extremely horny. After we fucked i cum in her, same cleanup after. Next day same thing. This went on for maybe 2 weeks. Then she said! You have been sucking and licking bobs up out of me for 2 weeks and didn't mind! Would you like to get it directly from the source?? Im like wtf. She says you have swallowed more of his cum then I have.!! I'm like saying ok, I thought you where just extremely horny. She then said she had invited Bob to fuck her just to watch me eat his cum. Not she wants me to suck him off for real just so she can watch him cum in my mouth. I figure what the he'll, im going for it. She set the date up. When he arrived she took him into the bedroom and suprize him, she tied him up and blindfolded him. She led me in to suck him off to complete. Without him knowing it wasn't her. I did as she wanted. When he cum in my mouth she was Very happy watching. She was going to dismiss me so she could untie! I stopped her. I started sucking again. When he was hard again I grabbed the bottle of lube, started some on my hand and lube my ass. Then I lubed his cock. I did reverse cowgurl. Her eyes got wide as I slowly sat on his cock. After he cum inside my ass I grabbed a facecloth and cleaned him up, also gave him a few sucks for good measure. She was really pissed he cum 2x and she was still horny. She let Bob go. She left me 3 months later saying I was a fag. Bob and I are still special friends
