The First Time My Girlfriend Had a Gangbang

This is a story about the first time that my girlfriend and i had a gangbang… enjoy!
One night after having sex with my girlfriend, we were both satisfied and happy and she asked me if i had any fantasys. We’d had this chat many times and she had always done as i had wanted, for example stockings etc.
This time as a joke i suggested a gangbang with about 3 or 4 men, thining that she would laugh and find it playful, she actually seemed to love the idea! She had gotten all moist again thinking about it. We talked about it and i actually liked the fact that another man would be pumping and dumping his load on my girlfriend. We decided to sleep on it and the next day we would talk about it.
The next day arrived and we were still keen on the idea, so together we posted an add on craigslist- Coventry (England) we didn’t expect many replies, so we left it for the day while we went out. when we returned home and checked our emails we were surprised how many men had offered, all shapes and sizes, ages, races.
We decided to only go with the men who had pictures, so we whittled it down to what she wanted. Now i am quite muscular with a good bodytype surprisingly she chose older man who were chubby/fat (very different to me) but it is what she wanted so i was happy to oblige.
We contacted the men back and asked when they would all be free, we decided that next Tuesday night would be best for everyone, we had no place to host so one of the men offered us all to his flat, so thats what we chose, his flat with two other men and me so she would have four men hard over her, four men wanting to fuck her brains out.
