I’m a 21 year old guy who was raised by a loving adopted family. I went off to college and met this beautiful 18 year old girl, and we hit it off instantly. When I met her mom, there was instantly a strange energy between us. When it was mentioned that I was adopted, she started asking really specific questions like my birthday and which hospital I was born in. After that she went very silent. It looked like she was fighting back tears at a point. Little did I know that I had just met my biological mother.

Three days after meeting me, she called up my girlfriend and confessed that she was my birth mother. She did some research to confirm what she already knew in her heart. When my girl told me, we were both in shock. My girl didn’t even know that her mom gave a boy away before marrying her dad. Apparently her mom was dating a man (my biological father) who was a huge ass hole. When she broke up with him, he got angry and raped her. That’s how I was conceived. She didn’t have the heart to abort me, but also couldn’t go through with raising this man’s son. So she gave me up for adoption.

My girl’s mom wanted us to break up. Our relationship was technically incestuous and there was a chance that our offspring would have health problems (if we ever had one). Hearing this hurt but I understood where she was coming from. I asked my girl if that’s what she wanted, and she shocked me by saying that it kinda turned her on that were related. She said she used to fantasize about having a sexy older brother, and that in a way this was like a dream come true.

We had the kinkiest sex of our lives that night, calling each other baby sis and big bro. Both of us came several times. Even though we had already fucked before this, it hadn’t felt taboo until now. We’re still dating and are becoming more serious by the day.

Any thoughts on how to smooth things over with her (our) mom? Seeing me has to be painful for her, and it will be emotional for me as well now that I know. I’d like to connect with her in some way, and meet my younger half-siblings. Most of all, I want to keep this amazing girl in my life.

I can share more details about our sex life if anyone is curious.
