It's my own fault really. Maybe I shouldn't have fucked Jenna up the ass like I had. I just couldn't help myself though. And, to be fair, she fucking loved it. That girl is a serious little anal slut.... And, it turns out we have that in common.
A few days ago, my sister and I both sodomized each other. She had pissed me off, so I came home on Monday and shoved my cock up her ass. I had felt so dominant over her. I fell asleep that night dreaming of all the ways I was going to use my sister as my little fuck doll.
However, Jenna had other plans. She tied me up while I was sleeping and dominated me instead. And, I have to admit, she was better at it than I had been. She sat on my face, slapped me around, and eventually fucked my ass with a strap-on. Afterwards, I was shocked at how much I had enjoyed it. As she walked out of my room, she said, "Matt, let's get one thing straight. You're my bitch now."
And, I was. I was her perfect little sex slave. For nearly a week, I did everything that Jenna asked me to do. Jenna was delighted by this, of course. We barely left the apartment for the next few days because Jenna was constantly horny and needed to use me. I obeyed when she told me to eat her pussy. I obeyed when she told me to lick her thigh high boots. I obeyed when she wanted my cock. I obeyed when she told me to lick her ass. She was very fond of making me lick her ass. In fact, it was one of her favorite things to make me do. Sometimes she would have me lick her ass while she was just watching TV or something; just because she was bored.
I thought my sister was over-sexed before, but it turns out I had no idea. She constantly wanted it. And, she was into pretty much everything. Once, she started spanking me, and then ordered me to spank her too. A couple of times, she attached her strap-on to my face and told me to use it to fuck her. And, of course she often used the strap-on to fuck me.
I would never in a million years have let a girl fuck me with a dildo if it wasn't for that night that Jenna tied me up and forced me. She had been so rough, yet I had cum while she was fucking me, and the orgasm I got from that was incredible. It was different and very new to me, but I will admit that I was into it. It unleashed my submissive side. I had always been the dominant one in relationships, but I now had the urge to be submissive as well, and I was good at it.
Yes, I couldn't have been a better sex slave. Of course, that's what I needed Jenna to think. It's true, I actually was enjoying being submissive to her. I still got to fuck her, and I liked that very much. However, I still needed to be dominant sometime. I knew I couldn't be submissive forever. Jenna could be a cruel mistress. She would often bring me to the peak of orgasm and then stop, ordering me not to cum and never finishing me off. She got a thrill out of giving me blue balls. I got back at her by jizzing on her toothbrush and inside her pillowcase. But, that was nothing compared to what I had planned for the weekend.
The idea had suddenly occurred to me on Wednesday. I had been Jenna's bitch for only two days at the time, but already desperately needed to find a way to get back at her. She was actually fucking me with her strap-on in front of an open window when the plan came to me. The first step was to drive out to a stud farm north of town and buy a horse aphrodisiac. They usually use them for stallions, but there is another one specifically for mares. I talked to someone who worked there to find out what would happen if a human were to take some. The way he described it was a sexual frenzy.
Apparently, the stuff was so strong that, if humans took it, they literally wouldn't be able to control themselves. This was going to be very useful to me. I bribed the man into giving me some. The second step of the plan was to talk to a frat boy. Normally, I hate frat boys, but it seemed I needed them for this.
There was a frat boy named Eric that my sister and I both knew. I explained my plan to him (not telling him Jenna was my sister, of course). In the end, there was little risk to him, and he got something good in return. All he had to do was invite Jenna and me to a party on Saturday. He invited us to the party at his fraternity, and Jenna said she would go. Perfect, now I just needed a little cunning to pull off the rest of the plan.
Saturday was business as usual. I woke up and went downstairs. Jenna was completely naked, watching TV on the living room couch. She only really wore clothes when she felt like it at this point. She called me over, spread her legs, and had me eat her pussy until she came. Then I had breakfast and went back upstairs. Typical morning for that week, actually.
Around 2:00 pm, Jenna walked into my room wearing her dominatrix outfit with her hair pulled back. She had the thigh high boots, the corset and, of course, the strap-on. I didn't even hesitate. I obediently took off my pants and got down on all fours. Jenna mounted me and started pounding me in the ass.
I had learned that her strap-on was double sided. There was a portion of the dildo that went inside of her as well. I guess that's why she loved using it so much. Jenna was in high spirits as she humped the rubber cock into my ass. It was filling me up so much that it hurt. Jenna was being really rough on my ass, stretching me out and slapping me. She was mocking me, trying to humiliate me even more.
"What's the matter, Matt? Forgot how to take a cock? Does my little fuck boy need a rest?" She continued to peg my ass for another ten minutes or so. I didn't get to cum, but that was alright. Just meant more satisfaction later, during the evening I had planned.
At 9:00, we both started getting ready for the party. Around 10:00, we were both ready to go. Jenna was wearing a sexy, tight dress that was sort of silver colored. It was very short, barely covering her ass. We were almost out the door, when Jenna suddenly decided to pull it up to her waist and shove my face in between her big cheeks. I pulled down the black thong she was wearing and licked her ass at her command while she rubbed her clit. 'Enjoy your dominance while it lasts, Jenna,' I thought to myself.
It was only a ten minute walk to the frat house. I had only ever been to a couple of frat parties, but I knew what to expect. We had to go around back and were let into the basement, which was the main party area. There was a bar set up, drinking games in every corner with a large beer pong table in the middle, a dance floor, blaring music and several couches along the walls. The place was packed. Jenna told me to go get her a drink while she went and mingled. I made my way to the bar.
Along the way, I saw Eric across the room. He had seen me come in and nodded to me. Good. Everything must be set. I got myself a beer and a vodka and cranberry for Jenna. The horse aphrodisiac I had gotten came in pill form, so I had crushed a half of one up earlier and put it in a small container. The man I bought it from said a whole one might be a little too dangerous. I stealthily added the crushed up aphrodisiac to Jenna's drink and delivered it to her. It was supposed to take at least an hour to start taking full effect, so I had some time to kill.
Jenna went off on her own to mingle and I decided to do that as well. Many of the frat boys were giving me strange looks. 'Those ones must be my recruits,' I thought. I talked to a few people, but never for too long. I really tried to find someone to get along with at this party, but it was tough. Drunken frat boys and sorority girls are generally pretty uninteresting people.
After 45 minutes or so of trying, I gave up and took a seat in a recliner in the corner. I was only sitting for about five minutes before Jenna came over and sat on my lap. We tell everyone we meet that we're roommates, so no one was weirded out by this.
"I fucking hate frat boys," said Jenna.
