It's in the middle of sex. Harry is fucking you like he always does, you on bottom and Harry hovering over you as his hips collide with yours over and over again. You always enjoyed this position because it was comforting and really all you'd known. You'd never had sex in any other position besides missionary, with your past boyfriends or Harry. But Harry wanted you to ride cock for the first time.
Harry knew from experience women loved riding dick because it made the cock feel deeper in their pussy's and allowed them to control their movements and do what felt most pleasurable for them.
So in the middle of thrusting his large cock in and out your cunt, Harry looked down at your pleasure ridden face and asked if you want to be on top for once. You gave him a nervous look but truly did want to try something new and to see what the hype around riding dick that women loved to rave over was all about.
As soon as Harry laid down on his back and helped you align with his cock with your tight hole, knowing you hadn't done this sex position before, you instantly almost loose it right then and there. His cock went so deep inside your pussy and you had to compose yourself before you started to moved.
Harry showed you how to ride him. He helped you plant your hands right above his breast and helped you bend your knees so they were pressed into the mattress on both sides of his hip bones. Then he placed both his larger hands on your waist and guided you through the movements for a few seconds, until you got the hang of it.
After a few minutes of riding his cock, Harry removed his hands and allowed you to take over completely, and you did just that. You ground your hips down harder and harder with each rocked motion, allowing your clit to rub against his trimmed pubic hair. You felt your orgasm soon approaching with how his cock perfectly stimulated your g spot from that angle.
Then when you were about to come, Harry grabs your waist again and helps you move faster and more aggressive, trying to push you both over your edges. And that's exactly what happened. Your toes curled into the sheets and your body trembled on top of Harry's, making you fall forward and collapse across his tattooed chest, breathing heavy and laying lifeless.
Harry had to start thrusting his hips upwards to meet yours (feet planted flat on the bed) because your body wouldn't and couldn't move anymore as your orgasm racked through you. With three hard thrusts to your cunt, Harry's load of cum shot up into your pussy and coated your slick walls.
After you both had came successfully, your body remained pressed to Harry's chest and you both tried to regulate your breathing. Then Harry asked you how riding cock felt and you told him it may become a regular position in your sex life because that was the strongest orgasm you'd ever had.
