I made my sister cum the first time we met

I

I didn’t know my sister existed for the first 25 years of my life. My dad fathered a girl when he was a teen before he met my mom, and she was given up for adoption. My very religious parents made a point of keeping this from me until I married myself, living in another country.

I’m not close with my parents; I stopped being religious and didn’t really have anything in common with them. So when I found out, I cared so little I didn’t even tell my then-wife. I pretty much forgot about her until we moved back to the states. We moved around a bit and ended up in a new state when I was 27, mid-COVID. Around the time I turned 28, I found out she lived near me, and her social media eventually recommend her to me. Still didn’t think much of it; never intended to meet her.

My spouse and I were nonmonogamous. I was on okcupid trying to find a new… Something. Had my setting set to non-monogamous or open people, and, lol and behold there she was. Her profile was clear: married mom of three, looking for a casual kink play partner. Odd first facts to learn about your mythical sibling. Out of curiosity, I swiped on her and she’d already matched with me. I messaged her, and she replied quickly. She asked if I recognized her, and I told her I did. We laughed about it being a strange way to meet for the first time.

Turns out she’d been adopted by a shitty religious family, and only recently had left the church as well. Her husband suggested nonmonogamy, and she went with it since she was kinky and he was on the vanilla side. We talked about our journeys and experiences in ENM, and I mostly shared the rosy facade I still believed covered my crumbling marriage (not because of ENM).

Kink was a pretty big part of her life, and she shared about it really openly. It wasn’t told to be salacious or erotic, though once she felt confident that I was interested and wouldn’t judge her, she became pretty blatant about the things she’d done and the things that aroused her. I didn’t consider myself kinky, but I still found it fascinating.

After a month or so of consistent talking, I suggested we get dinner sometime; we’d hit it off better than I expected. The weird thing is, I didn’t tell my spouse who she was; I felt odd admitting I’d had a secret sister I’d never mentioned.

My sister, Beth (not her real name), and I met at a cheap Chinese restaurant and she got us margaritas (I like my drinks fruity). She was physically what you’d expect a 40-year-old mother of 3 to be, but motherhood definitely worked for her. We had a few tattoos, one side of her head shaved into an undercut, and a pierced nose, but was still definitely a mom. I’ll admit I noticed, despite her being my half-sister. I also noted that we don’t look much alike.

Even in person, we both talked really openly and easily. We already knew each other well enough, and pretty much continued in as much detail as in text. Maybe more. I’m sure we scandalized the people at the other booths. We went for a walk through a local park after that, still talking. We walked and talked for several hours, then went and sat in her van and talked more when it got too cold. By then I knew the details of her family, her sex life, upbringing, and her insecurities (mostly her body). I was quick to reassure her about her body – a bold move for me under normal circumstances, I’m pretty shy – and she looked at me strangely for a second before blushing. That was the start of the flirting.

We were still in the van when the bars started closing up, and I made a joke about what usually makes the windows of a car get that foggy, to which she said it was the car hinting at something.

I said I wished it was. She said that wouldn’t be such an awful thing. I already knew her kinks, and, even though I’d never done anything kinkier than holding my spouse down or biting their neck during sex, I felt the urge to with Beth. Looking into her eyes, I reached over and grabbed a fistful of hair. She froze up, eyes wide, lips parted. I paused and waited. She nodded. I kissed her. Hard. I’m not sure how aware of her I was as a “sister”. It definitely crossed my mind.
