Story of my first cock

My ex-wife found my secret stash of photos on my computer and confronted me about them after I got home from work, at first I thought I was in BIG trouble but turns out she was turned on by them and wanted me to get dressed up and be her sub sissy right then. I was shaking and still in shock that I was hearing what I was hearing, I mean I had been a closet CD for years and all thru my first marriage, and here I was with the option to share something I love with someone I love. Seemed too good to be true. I went into the room and picked out a slip, nylons and panties, got dressed and we had the most amazing sex that night.
After that night sex was never boring and she was quite dominant which I loved, but she wanted more, she wanted to get a second sub/slave to serve her. I really didn't know how to react to that but it turned me on thinking about it so I agreed and we found a couple whose husband wanted the role and his wife was ok with it.
The first night we met I was all dressed up in a red slip, red silk panties, and black nylons. She told him to get undressed and on his knees the moment he came thru the door, his cock was HUGE compared to any toy I have ever used and I immediately got really nervous, she then had him service her pussy while having me suck his cock, which I did with pleasure for about 15 minutes until he was throbbing and about a thick 7 inches of hard ass cock, she told us to stop and had me take off my nylons and panties.
I was shaking because I knew the pain I was about to experience, she then grabbed our camera and told him to fuck me, so we went to the bed and he grabbed the 2 pillows and told me to lie on top of them with my ass in the air, so I did and he lubed up my ass and slowly stuck his cock in, it hurt alot at first and he told me to relax my muscles so I did and it actualy started to feel good, we still took it slow for a bit then she told him to fuck me hard until he cums, so he pushed my head down into the bed and started fucking me deep and fast, he had my hair in his fist pushing my face deeper the harder he fucked me, it was painful yet wonderful all at the same time, he fucked me for at least 5 minutes before he was ready to cum, he the rolled me over on my back spread my legs apart in the air and stuck his cock back in me and started fucking me again, I started fucking his cock back at that point and we had sex for another 5 minutes until he shot a huge load in me, it felt so great having that hot cum inside me and I was pretty hard by now.
My wife told him to go take a shower and told me eat her pussy some more, so I ate her pussy for another few minutes till she was nice and wet, by this time he was out of the shower and watching us, she then instructed me to finish her off fucking, so I kissed and licked my way up her stomach and stuck my very hard cock in her and started fucking her with a passion I couldn't even imagine, and she had him come lay beside us and watch, she orgasm'd so hard it felt like she was going to cut off my dick inside her, she was just gushing out cum, which was too much for me to handle and I came inside her.
After that we had lots of great sex but it was never like that first night, it never could be.
