My girlfriend has big breasts and is unfaithful.

This is a story about my girlfriend with her cousin when we started going out, she told me this months later and I really liked it a lot I wish it would happen again! My girlfriend is a cheap mora with big breasts, good body, and good face. Here's a photo of her. She tells me about an infidelity she had, we're from Mexico and this happened a few months ago! Judge for yourselves
