Her first cuck experience was huge

This the true story of my partners first gangbang. We had been going out for about three months and of course in the beginning you can’t get enough of each other. Karen is 40 years old, 5’8” redhead with very long legs. We were having sex every time we caught up which was 2-3 times a week.
After one session I told her that my ex-wife and I went to swingers’ parties on a regular basis. My ex and I had been married for 10 years. I then asked my partner, Karen if she would consider it even though we’ve only been together three months.
She asked me if I enjoyed watching strangers have sex with my ex-wife to which I replied yes. She then asked if there were other women at the swinger’s parties. I replied most times but not always.
Karen said she would think about having sex with other guys, but not with other women there. These conversations went on for a couple more weeks and then Karen I said I could arrange to have some guys fuck her that I knew and trusted from when my ex and I were swinging. Karen said if this was something in my life that I enjoyed she would do it for me.
Two weeks on I arranged for eight guys to show up, two black, six white and myself. Karen was initially freaked out at me inviting eight guys to fuck her, but I explained she would only be fucking two at a time and the others would be watching. That didn’t seem to help the situation much.
On the night we booked a hotel room and Karen had quite a few cans of bourbon and Coke to steady her nerves. Two white guys showed up early so we sat at talked a while. Karen was drunk by now and started flirting with the two guys and then kissing them.
I asked Karen to wear something sexy, so she had a black dress on that was cut up the back showing her arse. It was see-through and had a plunging neckline. I bought it from a sex shop the week before.
Anyway, the guys started playing with her tits then fingering her. Karen was getting really worked up and asked them to fuck her. Just then another four guys rocked up. I opened the door while Karen laid back on the bed with her legs open. One of the new guys walked up, took off his pants and shoved his cock in Karen’s mouth. She sucked it hungrily.
One guy slid up the bed and started fucking Karen. She asked if he had a condom on. He replied no. Karen just laid back and let him keep fucking her. He then asked out “can I cum in you?” Karen called out “Yes! Yes! Fill me!” This was something we didn’t discuss before, but I thought it was hot. After the first guy game I asked, “Who’s next?”
The guys were all taking turns fucking Karen. After the fourth guy had fucked her the two black guys turned up. Karen was super horny at this stage. I had never seen her this crazy for sex, but she was really excited at the thought of the two black guys fucking her.
“I’ve never had black cock.” She said as she was still being fucked by a white guy. One black guy pulled his cock out of his pants and he was huge. He shoved it into Karen’s mouth, and she could barely take it. “Put it in me!” Karen told him. The black guy smiled and waited until the white guy had cum.
The bed cover was soaked in cum. The black guy picked Karen up and turned her around into doggy position then slowly slid his cock into her wet, stretched pussy. Karen gasped out a “yes” as he slid in.
Over the course of the night everyone fucked Karen twice. Two fucked guys managed to fuck her three times. After all the guys left at around 2am, I fucked Karen’s wet and swollen pussy. It felt like velvet. She was so excited and asked when we could do it again. I suggested every weekend but she said she wanted it to be ‘special’ so we would do it every fortnight, which I was happy with.
From here things really accelerated.
