My former girlfriend with a big dick cheats on me

I used to be in love with my ex-girlfriend, but we broke up because she wanted to focus on her education and her job. I never suspected anything wrong with her, but it turns out she was cheating on me with my best friend. He's a big guy, kind of like a monster, and she's always been into that sort of thing. When I caught them together, I was shocked. She was on her knees in front of him, sucking his massive dick while he was stroking her back. It was a sight to behold, and it made me realize just how much I missed her. She's a cute little thing, with a nice ass and a bit of a chubby physique. It was clear that they were really into each other, and I couldn't help but feel a bit jealous. I couldn't help but wonder what it would be like to have her back, even though I knew it was impossible.
