I would never power fuck someone unless they asked for it, seems kind of cruel. But the few occasions where Ive had hard rough sex, it was a real turnon. The first was with my one and only cougar, when I was 17. She picked me up at a hotel swimming pool. We started off in cowboy, and she was thrusting up and down on me very hard, and balls deep. Up until then, I hadnt gone that deep with the high school girls I had been with, and the fast deep fucking made me cum rather fast. fortunately, I recovered fast, and we went at it missionary. She had her hands on my ass, and was pushing me into her, asking for me to fuck her harder. I started slapping it as hard and fast as I could, and we both were sweating and breathing hard. I loved listening to the sounds of her squishing pussy, and my thighs slapping into her. She came with a great moan, clamping down hard on my dick. I kept pounding away, and about 5 minutes later she came again, scratching the shit out of my back (Mom was suspicious of the marks later), and I came for the second time. After about 10 minutes of catching our breaths, she was playing with my soft dick, and within minutes we were back at it, this time doggy style. It was probably the hardest I have ever fucked, as I slammed her, I would pull her back into my dick with my hands on her waist. My nuts were swinging so far and fast, they were slapping her slit and then back to my taint. After I blew my thid load, the hottest thing was watching her creampie. The two earlier loads were all frothed up from mixing with her juices, and all the agitation. She had these really large labia, and see traced my cum over them and her clit with her fingernail.
