Fucked my G[F22]’s twin sister by [M24]istake

My gf Kylie has an identical twin sister named Kayla. When I first went out with Kylie, I would always mix her up with Kayla. They even played jokes on me and pranked me about this. But after a while, I caught on and could tell the difference between Kylie and Kayla. After Kylie and I dated for about a year, we moved in together.

There would always be days I would work late and didn’t get home until late. Kylie was already asleep most the time so I just crawled into bed and went to sleep while she slept. One time, after working late, I took the next day off and took a nap because I felt sleep deprived. I heard the door open and close in our bedroom and saw Kylie. Kylie came up to me as I was getting up from my nap and said, “hey babe. I’m horny. You wanna?”
I wasn’t a guy to say no to it, so I decided why not? Kylie and I started to undress as she got onto her knees and started sucking my cock.
I felt myself about to cum, so I told Kylie, “I’m about to cum!” Kylie kept going and I came in her mouth and she swallowed it all. Kylie wanted her turn so I got her into position and peeled her bottoms off and began sucking, licking, and eating her out. Kylie squealed out loud and breathing hard while moaning. I wanted to make Kylie cum just like she did to me and I could tell she was close as I could feel her body tremble and her left leg shake. Once Kylie writhed around and tried squirming away with a yelp, I knew I got her to cum. We started to fuck wildly like animals, multiple positions, but felt…good but different. I didn’t care and kept going until Kylie screamed, “Oh fuck yea! Keep going right there! Cum in me, please!” After I filled Kylie up, she collapsed onto me and I held her close and cuddled.

After catching our breathe, we decided to clean ourselves up. It was at that point I got a real good look and realized, fuck, did I just fuck Kayla and not Kylie? I said tentatively, “Kayla?” Kayla looked at me and said, “Yes?” My stomach sank and I was shocked Kayla would do something like that.
Furious, I screamed at her, “why would you do that?! I’m dating your sister, not you! Damn, I don’t think she’ll ever forgive me now.”
Kayla said, “calm down. Kylie always says how good you are and I wanted to try. And I agree.”
“How can you be so calm about this!” I screamed.
“Because Kylie and I fantasize about scenarios,” Kayla said. Not caring what Kayla said, I told Kayla to stay and I all I have to do was dreading the fact when Kylie came home from work soon. I gotta explain this to Kylie. I so seriously hope Kayla was not joking about her earlier statement.
