When you have her get on her hands and knees in front of you and move her hips up and down, pressing her pelvis into the floor before backing her ass up towards you…thats when things really go off the rails. You were just going to look! You swear it…but then, she was backing it up so seductively, she was practically begging for it! And so you got closer. You had her move her butt back, right into your lap. Into your rock hard cock, separated only by the thin fabric of your shorts, and her tight, tight spandex. You could feel the heat off her. What came next? Well, again, you can hardly be blamed! The way she was moving, you just had to get her on her back, and stretch out her hips…yeah, her hips…of course, you need to see things more clearly, you need to see her completely bare. And then, when you slip your fingers into her, that was just to check her…uh, core strength. Yeah. And when you made her cum on your fingers, even though she tried to hide the rise of color in her cheeks…well, then it was really her fault. And when she got back on her knees, backing up onto your now exposed cock, and kept rocking across it, the entire hard length, well…I mean…who could blame you, really?
