Expanding Horizons, Part I of III

By the time I’d reached my senior year in college, I still didn’t think of myself as being actively bisexual, despite the fact that for a good part of high school I’d had a sexual fling with my best friend, had done a threesome with two other guys one drunken night in college my sophomore year, and had discovered my own proclivity for having my ass stimulated. I still just thought of myself as a straight guy with a wild sexual streak, ready for all kinds of experimentation.

After all, I still dated women primarily and they were still the overwhelming source of my sexual experiences. Most of them didn’t know about my homosexual experiences, much less the pleasure I got out of having my ass filled. One girlfriend, Sara, had surprised me one night in the middle of fooling around when, as she was going down on me, she suddenly licked one finger and slid it up my ass. A jolt of electricity shot up my spine when she did it and she said afterwards that she could feel my cock get even harder and my balls tighten when she entered me. As she fingered me, massaging my prostate, I could no longer control myself and shot one of the biggest loads ever into her mouth.

“What made you do that? The finger thing” I asked her after I’d caught my breath.
“Well, you obviously liked it,” she grinned. “A girlfriend told me that you can make a guy cum quicker if you stuck a finger up his ass. I just wanted to see if it was true.” I figured it was all better left at that and just nodded in agreement with her friend’s wisdom.

A later girlfriend, however, came to know all about my experimentation with members of my own sex and loved to hear about it. Thea, though, was a wild one. Bisexual herself, she’d had sex with a number of female friends before meeting me and made no secret of her attraction to both men and women. She was, in fact, the one who broached the subject with me initially, asking if I’d ever fooled around with another man. I laughed when she asked, brushing the subject off. “Oooh, I bet you have, haven’t you?” she said, her eyes widening. I changed the subject, thinking she would let it die, but she pestered me for days to fess up about it and when I finally did, she insisted on knowing every detail.

I felt uncomfortable, for some reason, describing my experiences, I guess because I had never talked about them with anyone before. But as I did so and as it became more and more obvious that it turned Thea on to hear about my escapades, the more I warmed up to the subject. By the time I related the story of how I had ended up in a threesome with two other guys—of how a night which had begun with me and two friends out cruising bars trying to meet women had evolved, first into a drunken agreement between me and one of my friends to give each other head, and later ended with me being filled from both ends—we both had our clothes off and were masturbating furiously.

“I want to watch you do it,” she said when I finished.
“What?” I asked, surprised at the request.

“You heard me, I want to watch you do it. It would be so hot,” she repeated her request. I demurred, still taken aback at the thought that it would turn her on so much, but she was a wild girl, so I guess I shouldn’t have been surprised.

From that point on, my revelations opened a new dimension to our sex life. Thea loved to finger my ass while she went down on me. One night, feeling particularly turned on by the pressure of her inside of me, I kept insisting that she use additional digits, until finally she wasn’t even bothering to give me head, so focused was she on pleasuring my ass. She ended up with four fingers inside of me, thrusting her hand in and out as I moaned with more pleasure than I’d ever felt. She tried to get her thumb in as well, but that was too much for me to bear at that point. I had begun furiously stroking my rock hard cock and quickly shot cum all over my chest and face in long powerful spurts. Thea said afterwards that she could literally feel my rectum clamp down around her hand as I began cumming. It was an amazing experience for both of us.

Thea had more surprises in store for me still. The first came one night as we were fooling around. After I’d been going down on her and fingering her for some time, she suddenly said that she needed to go to the bathroom. I laid back on her bed, breathing heavily but incredibly turned on as I watched her adorable naked behind disappear into the bathroom which adjoined her room. When the door reopened, I couldn’t believe my eyes. Scanning down her body from her face, across her beautiful breasts, to her waist, I saw that she was wearing one of the biggest dildos I had ever seen strapped into a harness around her waist. It had to be at least ten inches long and I don’t know how thick. A change had come over her too. “I hope you’re ready for me, bitch,” she said lustily.

“What?” I asked, still surprised but now more excited at what she was up too.
“You heard me,” she said, walking to the bed. “Come here and suck me off.”

I couldn’t believe what I was hearing but I felt hypnotized by the massive dong between her legs. As I sat up on the edge of the bed, she straddled me, grabbing my head with her hands, her fingers clutching handfuls of hair. “Come on, bitch,” she growled. “Start sucking.”

She pushed the dildo against my lips and, involuntarily I opened my mouth and began licking her new “cock,” running it across my lips and taking it slowly into my mouth. “Mmm,” she cooed, “That’s right. Take it for me.” I sucked more and more of the dildo into my mouth as she fed it to me, her hips moving back and forth in front of me.

“Now take it all, you little bitch,” she demanded. I held on to her firm buttocks as she pushed it further into my mouth, the toy filling me inch by inch. I gagged a little at its size, but finally succeeded in loosening my throat enough to let her slide the entire dong into me. “That’s good,” she moaned. “Now it’s time to fuck my little bitch.” I felt the dildo pulled out of my mouth, glistening with all of my slobber from having been so far down my throat. “Now be a good little girl and get on your hands and knees,” Thea commanded.

She didn’t have to tell me twice and I was turned around, ass in air, almost immediately as she added KY to the thick sheen of saliva I had already put on her dildo. Thea climbed on to the bed behind me, grasping my hips with one hand as she guided the cock to my rectum with the other. “I’ve been waiting for this for so long,” she whispered. “I’ve waited so long to fuck you the way you deserve to be fucked.”

My mind was spinning as she entered me, slowly pushing the head of her cock into my feverishly aching hole. “Tell me how much you want this, bitch,” she whispered in my ear, as she began thrusting in and out of my ass, feeding me more of the dildo as she went. “Tell me how much you need it.”
I was completely caught up in Thea’s game by now and did just as she told me. “Oh god, I need it so bad,” I moaned.
“Tell me what you need, bitch” she demanded. “Tell me what you need.”

“I need your big fat cock inside of me. I need you to fuck me so hard,” I panted as the dildo stretched me out.
“That’s right,” she said. “That’s right, whore. Now tell me that you want it all. Tell me to you all of this cock.”
“Mmm, give it to me all. I need you all the way inside of me. I need your huge cock all the way inside of me,” I moaned out.
“Are you my little bitch?” she demanded. “My little whore? I’m only going to give it all to you if I know that you’re my little bitch.”
“Oh yes, yes,” I gasped, the dildo filling me so exquisitely. “Yes, I’m your little bitch. I’m your little whore. I’ll do whatever you want me to do, just fill me up with your cock.”
“Whatever I tell you to do, whore?”
“Yes, whatever you want. Your little bitch will do whatever you want”
“That’s what I needed to know bitch,” she moaned out, spanking my ass as she paused briefly in her fucking. She then thrust the dildo all the way into me, pulling me all the way back to her, her hips ramming against my buttocks.

Stars exploded in front of my eyes and jolts of electricity shot up and down my spine and scalp when she did it, bottoming out in my rectum with that enormous dildo. My own cock was pulsing now, so engorged was it with blood and lust. I felt like I might cum any moment as she fucked me and only became more turned on, if that was possible, each time she spanked my ass as she pounded into me, talking dirtier and dirtier to me as she did.

I lost track of how long our rutting went on, so lost in pleasure was I, but soon Thea began reaching down between my legs, running her nails lightly over my testicles at first, which made me shiver with a pleasure that was becoming almost unbearable. She must have sensed how badly she was teasing me soon, as she then ran her nails up the shaft of my cock before grasping it tightly. I moaned loudly then had to catch my breath, as she began stroking my penis, running her fist up and down its length in time with her thrusts into my ass.

That quickly sent me over the edge. My cock jerked, my balls tightened. Thea must have sensed it, because she thrust all the way into me in one long slow stroke. I came in a huge burst that felt like it was going to go on forever, blood rushing to my head and pulsing across my vision to the point I thought I would pass out. We were both spent after all of that, laying collapsed across each other in the bed trying to recover our breath and our senses. “That was so hot,” Thea finally moaned to me, nuzzling her face up against my neck. “I can’t believe how hot that was,” she repeated as we both fell asleep.

From then on, we took turns playing “the man” in our love-making sessions, often according to her mood. I learned to be open for whatever she might decide she was in the mood for—sometimes she wanted our more “traditional,” but still wild sex sessions; others, she wanted me to become her bitch and do whatever she demanded to service her enormous “cock.” But Thea, as I said before, would continue to be full of surprises.
