"I Can Fuck Her Better Than You" - A Threesome Feels Better When You Are Competitive

Everyone knows that my stepbrother and I are very competitive, but nobody knows how much. Today he brought his new girlfriend home, and all I could think about was how I could fuck her better than him. I had to prove my point, so I sent her some nudes I knew she wouldn't be able to resist, and when she told me she was straight, I knew I had to prove she only thought that because she didn't know how wet I could make her. Nobody licks a pussy better than me, but just when my tongue was tasting every inch of her, my stepbrother caught us. Any other guy would have broken up with her, but he's just as competitive as I am, so the solution was obvious. We needed a threesome to prove who could fuck her better.
