Pillow Biter

She loved it deep, on her knees, arms and shoulders pressed to the bed to afford maximum purchase. Deep, every boxer learns that the maximum blow goes through the target not just to it. Deep, all the way to and more, grinding with all her might into his pelvis, digging into the bed and using her whole back and shoulders to meet all his strength with her own. She didn't cry out, but a shockwave forced a gasp each time he struck home. She didn't care about him, she only craved the depth. Just a flesh piston with a muscular body to power it. She didn't care about her either, her mind was black, what focus she had was all in meeting the depth, never enough. When he exploded within her, she exploded herself and the blackness turned to light.   
She looked at him, collapsed and spent, men are so strong but so weak in their way. She could easily have gone again but he wouldn't be any good for hours.
"Oh well," she thought," I guess my brave little pony has earned his rest."
