My innocent girlfriend went through her “slut phase” while we were broken up [first time] [cuckold]

My girlfriend and I dated since we were 15 and broke up about 6 months ago. We were both waiting for marriage at the time to have sex but the breakup was bad and she ended up losing her virginity that night to a random guy. We’ve recently started talking again and she’s letting me go down on her all the time now but she’s had all this sexual experiences that I don’t. During the 6 months she went through a phase and uhh you could say had a lot of fun. Now she wants to get back together and is saying none of that ever even mattered and we can still wait until marriage.. So she wants to get back together after having all this sex. I honestly don’t even think she’ll be able to stop. She’s slipped up a few times since which I guess is understandable but it’s just crazy how fast she went from super innocent to a huge slut. A part of me actually likes it too which might be even crazier. She’s a totally different person now and I’m interested in seeing where it goes from here
