My girlfriend looks cute in bed with someone else. (True story)

[pony]

I'm new to the site, and just wanted to start by sharing my story. I've known my current girlfriend for 9 years now. We started out as just friends, she had her boyfriends and I had a boyfriend and a girlfriend during that time, too. Yes, I'm bisexual. My 2 relationships didn't get physical, and I was still a virgin. Her relationships, including those relationships she had before I met her, however, were physical. She was experienced with a quite a few guys.

Three and a half years ago, we ended up becoming more than friends, and she took my virginity. She has taken a few guy's virginity, admitting she enjoys teaching guys how to have sex.

One time when we were having sex, she asked me, "Does it bother you to know that other guys have been in there?" I thought about it for a moment. It didn't bother me, as a matter of fact, just thinking about it made me feel something, but not something bad. I told her it didn't bother me.

One thing she had told me in the past was that all the guys she has had vaginal sex with were not well endowed. Even I am not well endowed, at only 5 inches, just like all the others she's had. She had a love interest before me that was 7 1/2 inches, but only had oral sex, not vaginal sex.

One day when talking about it, she mentioned, "I guess I'll never know what a big cock feels like." kind of shrugging it off with acceptance. She said she would be happy with what I have. In order to make up for it (and because I wanted to do it, too), I ended up getting two cock piercings (frenum and prince albert) which she enjoys.

One day we met this guy, who I instantly was attracted to. She later told me she didn't find him attractive at first, but he kind of started to become that way. Moreso as I admitted it. I wanted to have sex with him, and I knew that my girlfriend had been in an open relationship with someone in the past. So I mentioned, "Would you have a 3some with D?" I expected a, "No way!" but instead she just kind of smiled, and brushed it off as not serious. But I teased her about getting screwed on both ends at once, and eventually she said, "If he wants to."

Not long after, I put the notion to D. He thought about it a while. He was homosexual but bi-curious, and later told me yes. So he came to visit us. Since he had never had sex with a girl, she got to teach him. I actually felt it kind of erotic to help him position himself to hump my girlfriend. Here I am, letting another guy stick his cock into her, and knowing she's going to enjoy it. And it excited me.

She gave me a blowjob while he humped her until he came into his condom. Shortly after, she enjoyed watching me get humped by him, later saying she liked to hear the soft sounds I made each time he humped. I felt so immasculated at that point. This guy had pleased my girlfriend, and now he was making me his girl.

Before long my GF and I wanted to make D a more serious part of our life. And he ended up being our BF. The three of us would play, sexually (usually him fucking both of us), then I'd leave the room afterwards when it was over. I'd notice the two of them are nowhere to be found, and would go back to the bedroom to find them fucking each other, again. I'd stay and watch. Before long, this happened A LOT. I'd walk in on them having sex. My GF couldn't keep her legs closed when she was around him. She was definately having sex with him more than me, but D made it up to me by pinning me and fucking me, too. Also, since we were all 3 serious, now, she allowed him to have sex with her without a condom, just as she allows me, too.

One day when the three of us were at a hotel, he decided to humilate me, which is something I really love. He made me wear a diaper and lay in bed next to him while he had sex with my GF. He even said, "You can't have sex with her." And she didn't mind those terms at all, either. I watched him humping her, and looked at the pleased look on her face. It seemed to last forever, and I thought my cock was going to burst from how hard I was. I wanted to fuck her badly, but I couldn't. And frankly, being in a diaper wasn't going to make my girlfriend think about me during this sex. And he gave her her very first vaginal orgasm. Until then, she'd never had one vaginally. I had given her orgasms orally and by hand, but never that way.

One time D and I both took cialis and took turns pleasuring Her. We came up with the phrase "Cialis is evil" because 4 minutes after finishing we were "in the mood again" although our bodies were still aching. We had sex about 10 times each in one day, taking turns with her.

Eventually, D grew apart from us, and we had no choice to break it off with him, which was hard on both of us. Neither of us had been fucked so well. And we had loved him. And by the way, his size was no greater than mine or the others, too, leaving her still curious about larger guys. It's like her curse.

But D had opened our eyes to a new open lifestyle. I asked her, "Do you want to be open?" She paused to think, and I added, "You can find out what a big cock feels like." She didn't hesitate to agree, once I said that. I made it clear that she doesn't even have to ask my permission. That way if a situation arises where she wants to do something, and I'm not around, she won't miss the opportunity.

I had later found out that when we were setting up our first sexual encounter with D, she had posted to her blog to all her friends about what we were planning, stating, "I've always secretly fantasized about having two guys in bed at once." Turns out she probably deep down wanted to be open all along.

When she and I have sex, I ask her questions during it, and make her tell me the truth. I ask her, "Is my cock too small for you? Tell me the truth." She says, "Yes..." I then ask, "You want to have sex with other guys, don't you?" And she says, "Yes." I also ask, "I can't trust you around other guys can I? You'd fuck another guy if I wasn't there, wouldnt you?" She answers with another, "yes..." Her answers drive me wild, and I can't help but to come just seconds after she says this.

Within hours of us deciding to be open, she posted to all her friends she's available. Within a few days she had a long list of friends who were interested in having her "visit". One offered to pay for a bus ticket for her to come up and visit him. That didn't end up happening because of schedules, though. But my GF didn't hesitate to flirt with guys and let them know she was interested in them sexually. I sometimes would catch a glimpse of her chat window, seeing guys type sexual things to her, like groping her between the legs along with comments about how much she'll enjoy when they do it to her in real life. And her replies not only welcome it, but encourage it as she flirts back.

One day, at a con, we met up with a mutual friend of ours, K. We had met him in her hometown before we had moved, and this was a rare opportunity to see old friends. Sometime during the con, she went off to socialize while I did the same (at cons, its typical to split up and do various things alone). She went off to hang out with K.

K is someone who is somewhat straight and bi-curious and had expressed interest in both of us. However he had a GF who was flakey and would agree that she and K were open, then disagree, so me and my GF really took K's open-ness with a grain of salt.

However, later that night she told me that she was really horny and that she and K had "dry humped" doggy-style. What she said next gets me aroused everytime I think of it, "If I had a condom I would SO have had sex with him." I wish I'd have given her some condoms. She also added that another male acquaintance of ours, P, was in the room watching them dry hump, and he expressed his desire to have vaginal sex with her.

Ironically, the next night, K was really horny, but this time, wanting to hump me. I would have been all for being his first male experience except it was really late and I was beat, however, I said, "If you can get a condom, sure." He didnt have one, and so I suggested he go knocking on hotel room doors asking for one. He wouldn't. To my surprise, I later discovered that in the side pocket of my bag I had a condom and a packet of lube, which I kept in case of emergency (but had forgotten). Oh well, sorry K.

The next day at the convention, another friend of ours, V (who was P's boyfriend, both bisexual and open) stuck his hand down her pants and panties and rubbed her clit in our room, in front of me. She had invited him to, because they had set it up in advance of the con that she would teach him female anatomy (another bi-curious guy with no female experience, yes). V is sexually attracted to us both, and with me and my GF being in an open relationship where we both want to have casual sexual encounters with our close friends, its only a matter of time.

At a different con we met two of our mutual friends B and R, both guys and boyfriends. B and me play wrestled in the bed and had brief (incomplete) sex with one another, both ways. I didn't realize it but meanwhile in the other bed my GF was giving R a blowjob and swallowed his cum.

So that brings us to now. She still hasn't experienced more than 5 inches. And we are about to move again. When we decided on a place, she immediately followed, "Thats where V and P live." I didn't even realize that. Our new lease is set and we move in a month. Now she'll be one bus ride away from visiting two guys who I know are interested in her sexually and that she is sexually interested in, too. With no rules to stop her from going as far as she wants, I don't think she'll forget to bring condoms when she goes out on her own to go hang out with them. I'm sure I'll hear her come home one day to tell me she went all the way.

The way things are is great. If I'm feeling particularly feminine, I get to be fucked by guys, which she enjoys watching, too. And if she's in the mood for variety or multiple guys, she gets that, too. And as a bonus, I get to see her having sex with other guys or hear about it. Thinking about that always gets me horny. I find it hard not to cum immediately at the thought when I'm masturbating.

Its obvious to both of us that I'm not enough man for her. With this arrangement, I can be what I am and she can get pleased as much as she needs.
