This is very detailed, kinda long but hot if you like it this way. I love writing about sex it's sort of an addiction. Reliving a hot night you wish you could have again ;-) Part I We've been on and off for 4 years. She would get down on her knees to give me head, dress up, take it from behind, whatever I wanted. But she has changed a lot and now I know why. I am generally not a guy that likes to be on bottom. Though I am somewhat bi, I've only felt this way with one person, a guy. But fucking her is the highlight of my sex life. She sucks cock with tight lips and can get me off in under a minute. She's kinky and takes it like girls should. Though sometimes, she gets in these dominant moods and I love it. She likes to tie my hands together in front of me and do whatever she pleases. All fun... but I think the dominant side just came out permanently. And I can't help myself anymore. I love it. Her aggression and my hopeless attraction to her built up a hot night passion of not only her having her way with me, but making me admit I love it. As a man, I would never have admitted it before. But it's been building and I been liking this more and more. It was New Years and we were going out of town for some drinking and we got a hotel room. It started while I drove to meet her. I was in a very cocky mood and made a remark about her begging me to come. She pointed out how I was driving to her and told me that she was in control of the relationship. I said that I was. Little did I know I would be getting shown who's boss later and getting off on it. Just a small argument for power basically. We did this a lot and always make up with hot sex. At the end of the night she was in a bad mood cuz I was checking out a skirt. We've done two threesomes and I suggested I would love to see them go at it. She got mad and was mean to me when we got back and told me I wasn't getting any until I behaved. I always knew I liked being submissive to her. But it was never something I was sure I could go all out and do with her. We get kinky and have done lots of variety. But over the last year she is on top 90% of the time and finishes on top 100% of the time. I did this because she gets off easier this way. She also gave me my first orgasm on bottom, which I could never do before she fucked it out of me one night. I knew what was happening and that I had a strong desire to pleasure her. It gradually became what I wanted. I love her beautiful body on top fucking me. I love to watch her work my cock nice and hard while she gets off. Some girls are just so hot when they get loud and breath hard. It's made me cum many times seeing her build up an intense orgasm. Watching her get off on top of me gradually became the way I got off. It worked out nice. Seeing her move like that is my peak and I blow while she's cumming. Perfect. But putting it out in the open is what I liked. As always, I didn't want to have a bad night. So I began to make her happy. I gave her a full body massage. I felt my hardness rubbing into her ass while I did it. I wanted to fuck so badly and she told me no. She was making me work for it. I found myself saying okay and telling her I wanted to fuck her to fuck me so badly. I gave her exactly what she wanted. I can't resist her after a whole week of not having sex so I did as exactly as I was told. It turned me on so much. She knows exactly how to push my buttons and get her way. And when I start changing to please her, it became so obvious I was helplessly under her control. May favorite position was what I liked because it was what she wanted. After 30 minutes of torture. I told her I can't take it anymore. I started kissing her neck while touching her ass. It's a nice tight, firm ass and it drives me wild. She's got great tits. She gets hit on endlessly because it's the perfect set of C-cups. She knew how to dress and has so many times got me to fuck her when she wanted just by revealing her huge breasts for me.I told her I wanted her badly as I rubbed my cock up against her ass. I strategically asked her, "Can I please fuck you now". She said "yes, put your dick into me NOW." I pulled down her panties and put my hands on her bare ass. I told her how she has the hottest ass I've ever seen. "Put your cock in me already" she says! While in a spooning position, I pried open her nice tight pussy with my raging hard cock. Our favorite part. I would put my head into her and thrust every inch of my cock into her hard and fast, just the way she liked it. I moaned out loud it felt so good. I was rock hard and been wanting to get inside of her desperately. But only I got a taste after my penetration into her. She told me to lay down. I got excited knowing she wanted to take control right away. I was pre-cumming in anticipation and told her I wanted her on top while she fucks me.I laid down for her immediately. As she kneeled over me, she took my hands and put them on her hits. I started to pre-cum in anticipation. She got on top of me and slid her warm, wet pussy down my hard shaft. I was in pure sexual bliss as I put my head back. I felt her hips move back and forth over me as she grabbed my hands and placed them on her hips. I tell her how long I've been wanting her to fuck me. She tells me "I know you like it when I fuck you like this". I felt so helpless. She didn't need to tie me down to dominate me. I was obedient all because of how amazing she made me feel. More so than I could do if I were doing whatever I wanted to her. She gave me the most amazing sex and there is nothing I can do to get it. I was at her mercy for what I needed and I knew it. I looked up at her and started to moan and say "fuck me, fuck me harder" like she used to do to me. She got more aggressive and I could tell she liked me asking her to fuck me. "You like getting fucked don't you" she says. I say yes and tell her I need it. She said things to me and I was helplessly submitting to her. Telling her she owns me. I said said "oh baby, i love how fuck me". I am one for making noise and talking during sex. We both do it naturally and it makes for better sex. She asked me over and over, "you like that. you like that huh". It was such a turn on I had to focus and stop myself from cumming. "Fuck. It feels too good." I saw her satisfaction in knowing that I was about to cum soon. It revealed how turned on I was. I've been wanting her to go all out of me for so long but I wasn't ready for us both to play our roles so perfectly. It was natural and very stimulating.
