During the early months of Alena's pregnancy, the three of us continued to get together for casual fucks. It was honestly a little bit nice that some of the emotional intensity drained out of the experiences - they were simpler, more lustful. On one memorable occasion, I hadn't cum for a couple of weeks, and creampied first Kate, then immediately moved to Alena and finished in her within about ten minutes, while Alena ate my creampie out of Kate's pussy. Kate liked that idea, and they started licking each other at the same time - very fun to see two women sucking my cum out of each other's pussies. I never did ask about the... supposed IUD. The risk was tantalizing. Nothing ever did end up coming of it, though, so I assume Alena was just giving me some fantasy material. I continued going on dates, but not finding too much interesting in them, and keeping myself occupied with Kate and Alena.
That is, until I met Samantha, Sam. A mutual ex introduced me to her telling me we would be a perfect fit. "She's the only person I've ever met who's kinkier than you," was the only endorsement I needed before asking Sam out. We immediately hit it off. We shared interests, had a good rhythm to our conversations and compatible senses of humor. She was a sculptor that had recently made a big break with some media attention, so could now basically sell one or two pieces a year and live off the proceeds. And she had this uncanny ability to see small details, notice things that would pass everyone else by, and a curiosity that made me open up and see the world in a new light. I was head over heels for her right away, and told Kate and Alena I would have to put a possibly indefinite pause in our extra-curricular activities.
And my friend was right about Sam. She was a kink machine. Assertive, almost brash in her daily life, she became a complete brat and a sub in the bedroom. She enjoyed getting her boundaries pushed, and by our third night together, I was fucking her in her apartment, breasts pushed against the glass of a totally uncovered window, where the whole world could look up and see her exposed. She was bi, and sometimes her task would be to go out unicorn hunting, and find someone who she could bring home for me to fuck while she watched, or joined in. There was barely anything she wasn't willing to try once, or three times, and she had a sex drive that was higher than my own.
Within a few months, I realized this was someone I would want in my life for a long time. Maybe forever. I had never once felt judged by her, so I decided to open up about the experiences I had with Kate and Alena. I wanted to her to know all about me, and if we were getting serious, didn't want to have any big secrets. Ticking time bombs that could blow up at any time.
We were sitting on the couch, chatting, my arm around her, and I tried to approach the subject delicately. "What do you think the most shocking thing, or like, shocking to the average person, you've done sexually is?" I asked her.
"Hoh, man, that's hard to pick. I mean, you already know some of them. I mean, I put a reddit post up asking people to suggest things to fuck myself with, then posted those videos. That's pretty shocking. I had a guy pee on me once. I wasn't really that into it, but that's pretty shocking." She started stroking my arm, with her hands, her light touch tracing little circles on me. "Why? Are you thinking of something especially vile you want to do to me?"
Fuck, I loved that's where her mind went. "No, I think I'm already running out of creativity in terms of findings new vile things to do with you, to be honest"
"Oh, I doubt that," she said, draping my hand against her chest. She was about my age, and her tits were very large for her frame, at the cost of starting to sag ever so slightly. I still adored them. "If not that, then what were you thinking of?"
"Well, I have something in my sexual past... something I think you should know about. But it's... well, it's something that not everyone would be cool with. So I've been looking for a way to talk to you about it."
She shifted on the couch, putting her feet between us, so we could look directly at each other as we talked. Her face was impassive, curious as it looked into mine. "Did you hurt anyone?" She asked. "I mean, like, do something someone didn't like?"
"No, nothing like that."
"Do you have an STI or something I should know about?"
"No, no," I laughed a bit at this. "Nothing like that either."
"Well, if it doesn't fall into one of those two categories, I can't imagine I'll have a problem with it! But go on, spit it out. You can be open with me. Even if it's not my thing, I'm not going to think differently about you."
"Okay," I took a breath. "You know how I was Alena's sperm donor? Well, they were having a hard time, and Alena was struggling with the medicalization of all of that... so, they asked me if I could just... cum in her. Instead of cumming into a cup. And I agreed."
Sam kept looking at me, inquiringly, clearly she thought this wasn't the whole story. "So... that's it? You fucked your sister's wife?"
"Well, and Kate was there. And... she helped."
"Ah." Sam looked at me, the gears turning in her mind, things falling into place. "I bet she didn't just help, did she? Things got a bit out of hand and went further than that, didn't they?" Damn, Sam could always jump one or two steps ahead.
"Yeah."
"Do you want to tell me more about it?"
"Do you want to hear about it?"
"Kinda."
"Okay... well, here's what happened." And I told her all of it. Our initial negotiations, how we had this crazy idea that it was going to be kind of asexual between Kate and I. Alena's incest kink coming out. My incest kink coming out. Alena sending Kate in, that first time, to help me jack off in the shower, my cum spraying all over her body. The weekends spent together, mostly in bed, filling Alena with cum while Kate sucked, toyed, got off. Alena realizing I was into Kate, and pretending to be her while she rode my cock. Me realizing I had feelings for Kate, and that I wanted more than I could really get from the two of them. That night by the lake, where I made love, truly made love, to Kate for the first time. Continuing to hook up with them, just for fun afterwards.
"So... are you saying there was an overlap? Are you trying to tell me you kept fucking them after we started dating?"
