I liked that she was worried I might leave her for other girls. Several times we agreed there were no commitments between us, but I knew she was not fucking anyone else and always acted jealous of any girl I talked about or eyeballed when we went out. It kept her doing things for me a lot of girls wouldn't.
Doing more and more daring and perverted things kept things interesting for me. I mean, why spend time and effort picking up some new babe in a bar who might give me a quick BJ or a boring fuck when I had a girl like Laura who was so willing to please me? Over the next few weeks I had Laura do all kinds of sexual things for me. I made her dress up in costumes, let me spank her, let me push a dildo up her ass while I fucked her cunt, stuff like that. Sometimes she objected, but usually she eventually went along with it. She often gave in when I got quiet and cold, or when I acted like I was getting bored with straight sex.
One night I brought over some of my old silk ties and a blindfold. Her bed didn't have bedposts, so I had to rig some leather belts to make loops from the corners of the metal mattress frame to the top of the mattress. Then I used the silk ties to bind her hands and feet to the belts. It worked quite well. I kept the bindings rather loose but made sure she couldn't move her limbs more than 6 inches. The blindfold and a set of stereo headphones added the final degree of vulnerability. Unlike some other sexual games we played, Laura agreed right away to be tied up, thinking it would be fun for both of us. And it was. I ate her out a couple times, tormenting her by pausing just short of orgasm until she begged me to finish her off. I enjoyed teasing her and exerting so much control over her mind and body. I climbed on top of her a few times and made her suck my dick. I also fucked her hard while she lay spreadeagle. It was fun but it was actually less satisfying because she couldn't use her fist to pump my shaft during oral sex or her fingernails in my back during missionary sex. But it did have a kinky kind of fun about it that kept things interesting between us for awhile longer.
The following weekend, I left town for a business trip and didn't see her for a week. It was the longest period of time we didn't fuck since we had met six weeks earlier and I was pleased how desperate for me she sounded when she called me on my phone a few times. I told her she could only call me twice that week and only between 7pm and 8 pm. She broke the rule, though, and called me four times. I took three of the calls but ignored the fourth one because it was almost midnight and I was in the middle of fucking a chubby thirty's-ish young woman I had met at the hotel bar. She was at least 25 lbs overweight for someone her height, but she had bigger tits than Laura and I found burying my face in her soft grapefruits was a nice change from sucking Laura's pair of peaches.
By the time I got back in town that Friday night, I was horny for her again but tired, so even though I told her I would come by, I skipped it and went to my place instead. The next morning she called me and acted hurt I didn't come over. I played hard to get and she fell for it. I acted almost annoyed with her, even though I could hardly wait to see her.
