Once I was digging in hard pounding just the right spot. She dug her nails into my back, threw her head back and yelled at the top of her lungs "ooooh Gaaaawwwd, put your tits on my ass!" I kinda snorted/chortled and tried not to laugh but she realized what she had said made absolutely no sense and we both started laughing our asses off. Later she said I was literally fucking her senseless.
