This is the sequel to 'Dating A Sex Addict Ch 01' about my sex addicted girlfriend Sarah.
*
Sarah and Lila began spending more and more time together, sometimes with me, sometimes without, but to be honest I found that the longer it went on, the better I felt about it. I know technically Sarah was cheating on me but weirdly, I think the thought of being cheated on was what really upset me because I had always assumed it would be upsetting. The reality was that I actually didn't mind sharing my girlfriend and I didn't see it as her lying to me or betraying me. The added bonus of course was that I got to keep fucking Lila as well, and we actually grew to really like each other. A few weeks after our first encounter, Sarah was away helping her mother with something so she agreed to let Lila spend the night alone with me. I think it was Lila's idea though as she was a little coy about it and she seemed just as excited as I was. She stayed at my place and we spent hours pleasuring each other, a little less urgently than we do with Sarah because there was no urgent need to get her off. Lila was insatiable and by the end of the night, she had let me fuck her in the arse, which she told me she had only done with Sarah and a strap on.
Things were going great but part of me began to suspect that Sarah wasn't only seeing Lila on the side. On one occasion, I called her and I could hear her grunting and groaning. That wasn't too unusual on its own and she told me she was masturbating, but I could swear I heard another guy grunting in the background. I noticed that she had become bit unpredictable, visiting people at random and making last minute plans, but with Sarah, it was difficult to judge what kind of behaviour was really unusual. I think if I was honest, I knew what was coming but I just didn't want to admit it and eventually the inevitable happened, Sarah came over to my place one night and said she had to confess something. I almost knew the story before she told it to me but still I sat there while she told me how she had been to see an old friend after work that day and one thing had led to another.
Again, I was surprised that I wasn't more upset as she told me that she was really horny, and that she had only gone over to see her friend but before they knew it, she was bent over his sofa and he was fucking her from behind. She really did seem remorseful and she assured me she hadn't let him cum inside her but then she stopped and looked away from me hesitantly. I knew what was coming and we went on to talk about how deep down, we both knew that I wasn't enough for her. It wasn't me specifically, it was that no one would be enough for her; she just needed sex all the time. She said she hated this situation as she didn't want to cheat on me but she knew she could never just be with me. I think deep down I had been expecting this and although it wasn't easy, I felt more prepared than I had expected, and over the next few days, we agreed that we would try including other people in our sex life. We agreed that this would definitely be a mutual thing, she wasn't just going to go off fucking other people, but we would start by having a session with Lila and another friend of hers. Not really knowing what to expect, I agreed and we arranged to do it at Sarah's place that weekend.
That Saturday, I got to Sarah's place in the afternoon and she greeted me at the door, totally naked and barely able to contain her excitement. Although I wanted to save my energy for when Lila and Sam showed up, I did agree to finger Sarah and then I ended up eating her out once as well. She was almost out of control and was busy shoving a dildo inside herself when they arrived so she asked me to let them in while she freshened up. When I opened the door, I found Lila looking as gorgeous as usual in a tight grey dress, and a good looking guy about my age with her who smiled and introduced himself as Sam. I invited them in and we chatted a little awkwardly for a couple of minutes and I found that I quite liked Sam. It felt weird because essentially I knew he was there to fuck my girlfriend but as much as I wanted to be a little hostile toward him, he was just such a nice guy.
I had got them a drink and made some small talk by the time Sarah practically skipped into the living room, now dressed in a skimpy silk dressing gown, and greeted them both with a big hug. We chatted for a few minutes, somewhat unsure how this was supposed to work, and I quickly found out that Sarah and Sam had met before but never had sex, and that Sam had fucked Lila before but not recently. Sarah seemed more comfortable with this than the rest of us so she suggested she and Sarah break the ice by getting started, and Sam and I could watch. By now, I had seen Sarah and Lila pleasure each other many times but I never got tired of the sight of them undressing each other and rubbing their right bodies together. Sarah wasn't wearing anything under her dressing gown so she was naked in a few seconds but when Lila had peeled off her dress, Sarah knelt in front of her and pulled her panties off before spreading her legs and pushing her face between them.
I guessed that Sam hadn't seen anything like this before because he looked like he could barely contain himself, but weirdly I felt a little bit proud that I had. It made me feel good that I was more experienced than him and I decided to own the fact that I was letting this happen, rather than being a bystander. I stood up and took my clothes off first, and after we watched Sarah quickly eat Lila to an orgasm, and then Lila return the favour, I stepped up towards them and asked "right, where do we go from here?"
