One time, I decided to push things. I started a journal, and wrote stuff in it. I wrote that I loved her, but felt my bisexual feelings and emerging desires for men taking over. I also wrote down that I wanted some new kind of sex that she couldn't provide. I emphasized that I wanted masculinity and energy in my bedroom, something she could not give. Then, I casually put the journal under the mattress. A place where she would be sure to discover it. Surely enough, she did. Karen has always been a proactive gal who believes in going to great lengths to please the man she loves. She didn't want to lose me to a man. So, she decided to spice things up in the bedroom. Unfortunately, my wickedly manipulative plan almost backfired. Things almost took an unexpected turn. Yeah, that's what I thought when she brought a strap-on dildo to the bedroom. I quickly refused. She looked at me, confused.
Apparently, she'd been watching too many bisexual videos online. She thought all bisexual men loved getting fucked in the ass by women wearing strap on dildos. I told her that even though I was bisexual, I was a top, not a bottom. Meaning, I was interested in fucking someone in the ass, not the other way around. Karen looked at me, surprised. She sighed, saying something about bisexual men being far more complicated than she previously thought. I smiled, and nodded understandingly. I looked at her lovingly. Yeah, I knew which looks she always fell for. suddenly, a light went off on her head. She knew exactly how to "cure" me of my desire to have sex with men. I told her I was all ears. She told me that since gay guys loved anal sex, maybe bisexual men felt the same way. All she had to go was take it up the ass. I smiled. I am good, aren't I? I manipulated her completely, making her do what I want and letting her think it was all her idea. I deserve an Oscar, but I'll take her booty as my prize, thank you very much.
Karen took me by the hand and rushed me into our bedroom. There, she eagerly got on all fours and spread her plump butt cheeks wide open. I grinned, and pressed my cock against her butt hole. Then, I pushed it inside. Her ass was so tight. I could tell that she was an anal virgin. I decided to be gentle with her. I slowly worked my cock into her butt hole. Inch by inch, I fed her hungry asshole my cock. She screamed. She howled. She creamed. In the end, she begged me for more. I held her by the hips and thrust my cock deeper into her booty hole. Deep down the tunnel of darkness. How I loved thrusting in and out of that butt hole. Knowing that I was the first and indeed the only man to shove his prick into her asshole filled me with a feeling I found hard to describe. It must have been how Christopher Columbus felt when he discovered America. I fucked Karen's asshole like there was no tomorrow. In the end, I came, sending my hot seed deep inside her. Down where the sun didn't shine. We both screamed passionately as a rock-hard orgasm overtook our bodies.
Since that first experience, Karen has never been the same. I swear, she never knew how much pleasure a woman could have by allowing herself to be anally penetrated. After discovering it, she couldn't get enough. I can't even begin to tell you the number of times I came and found her playing with herself, a massive dildo buried inside her asshole. Yeah, she's become an anal addict. And I created her! She loves me dearly and still thinks that I am bisexual. Since I can't be sure how she'd react to the truth, I never confessed it to her. Besides, what's the harm? I did make her swear not to tell anyone about my "secret bisexual lifestyle", though. She winked and told me my secret was safe with her, as long as her secret was safe with me. Apparently, she didn't want people, especially her girlfriends to find out that she loved getting fucked in the ass. It was her dirty little secret and one I was happy to keep. After all, I didn't tell any of her girlfriends. I did tell all the guys at my favorite bar, though. Now that's not breaking a promise, is it? What? I didn't tell her girlfriends, I swear!
