There was a long silence then a heavy sigh.

"Stephanie...you are adopted." I was ecstatic! "And Eddie...sigh you are too."

"What!?" we said in unison.

"Its true. I picked both of you up at the orphanage on different days a few years apart. There's no blood between you. I'm sorry to have to tell you this so suddenly." I assured her I bore her no grudge. After I hung up, Eddie grabbed my boobs from behind and stuck his cock inside me before I realized what was going on. But when I did, I moaned long and loud as he pumped my pussy with his hard dick. My pussy didn't hurt from being deflowered anymore, so I humped back to meet his thrusts and soon I was cumming hard and so was he. Eddie shot another big load inside me, then another after some fast fucking.

From that day on, we were fuck buddies. Even when nobody else came with him, Eddie still snuck into school, found me and fucked me. He always made sure to cum inside my cunt, just because he knew I loved it.

Later, we went to find out who our real parents were through the genealogy part of the library. It turns out, that while 'mom' did adopt us, our parents were the same people. Eddie and I are full-on siblings.

We fucked again that night. Not like we can go back and not have sex now.
