I've been a cuckold this whole time

About a month ago I finally got my girlfriend to admit she's been fucking other guys pretty much since we started seeing each other. We had been fucking for a while and I had her really horny. I started asking her questions and slowly got around to asking how many men she has fucked since we've been together.

She said none but I could tell it wasn't the truth. I told her that I was sure she had fucked someone else and that I wouldn't be mad if she told me. She thought for a while and said three. I got the details of when this all happened: the first one was not too long after we got together, while I was out of town for a while; the next one was during a week when I was having doubts about the relationship and told her I needed to take a break and the third was while I was out of town again. All of them had bigger cocks than me (which isn't too hard).

I told her that since she had lied to me (I had asked this a few times before) that I wanted to see her get fucked by another man. She agreed and I contacted a man who had come over a few times to watch us, just as a voyeur. She had jerked him off a couple times but had never fucked him. I didn't tell him what the plan was but was sure he would want to fuck her. So he came over the next morning to watch. As usual he got naked and my gf started giving him a handjob. He's an older man, maybe late 50s and has a decent sized cock, maybe 7.5" or 8" and over 5" around. I'm about 5" by 4.25" around. As I was fucking my gf I asked if she wanted to feel him inside. She just gave me this sexy look and I asked him if he had a condom. He was wearing it in about 2 seconds! She turned around and got on her hands and knees and was sucking me off while he got behind her and put his big dick in her pussy. I could see he was having trouble holding back and he only lasted maybe 3 or 4 minutes. I think he was uncomfortable with the situation after he could think straight again and left pretty quickly, leaving my gf with a freshly fucked pussy. We fucked for a while after he left. Her pussy felt so nice and open.

Since then I've found out there were even more guys. Another this past winter while I was out of town, one this summer while I was out of town, one about a month and a half ago and the last one just over a week ago! This was all while I was out of town. That last one was only a week after I had last fucked her and we haven't fucked since. That makes 8 guys she has fucked since we've been together! And she seems to only be attracted to well hung men, all of them were significantly bigger than me with some being pretty huge. I love how she's very open about telling me details like this. She claims that she's now told me everything but it's hard to believe her after it took so long to get her to admit to all of it.

She's agreed to let me find a man for her as a booty call. So I'm going to be looking for someone who's into this kind of thing. I'm not living in the same city as her right now and she has an extremely high sex drive. Hopefully I'll have updates on that soon.
