Debo follarme a mi novia si tanto me lo pide?

Hello friends, I hope you're doing well enough, okay so I don't know where to start. It doesn't matter, good two weeks exactly, my girlfriend sent me a indirect message like Would you like to play with a pair of melons? at first I didn't understand but little time I realized what she exactly wanted to say, I told her to tell me more information and she said she wants me to break her ass, I got shocked, since my girlfriend never said anything like that before, and obviously it was the first time she said it to me. The truth gives me a lot of pain fucking her as much as she says, and I would like to surpass her expectations, but as I've told you, it gives me a lot of pain. What do you recommend? Maybe should I fuck her or should I wait a little more? Any opinion is valid, thank you in advance for your attention so appreciated. Edit: I'd upload screenshots of the chat, but I'll get screwed if I post without permission, later I'll tell you if I can upload the captures for better credibility.
