Got a little too drunk and thought it was my gf

A couple of nights ago I went out with my girlfriend to do some bar hopping around town. After a few bars my gf and I get to a packed club with little lighting and loud music. She goes to the bathroom after a bit because she doesn’t feel well and later goes home with a friend and sent me a text about it but I didn’t see.

I was about 7 drinks in and feeling it. I went into the dance floor and found someone that looked almost exactly like my girlfriend from hair to shape (No she does not have a twin). I start dancing with this girl and because of the light I can’t really discern who she actually is. She starts grinding her ass on me and with all the alcohol flowing through me and not great decision making I get pretty horny from it and start grinding up on her.

This girl looks at me with a little surprise from how big my dick is. I smile back and ask her if she is ready to head home and maybe take a full look at it. I normally wouldn’t be so direct with anyone but the booze was really affecting me. She nods and bites her tongue. I take her to my car still not knowing who she is and it’s already midnight by now so I take her home and we race into my room already making out on the way. It’s still dark in my house so we stumble to the bed. My girlfriend has some huge naturals and a fat ass and that’s what I’m expecting here. After I rip off this girls clothes some huge titties jump at me and they are great but you can tell that they are fake with how hard they are. I don’t get super suspicious because I’m really drunk but this girl’s ass is a natural beauty with its soft cheeks. I feel a little confused cause things feel a little different but I think it must be the alcohol playing tricks.

I then lube up my dick with my spit and shove it between her boobs. She then starts using those huge jugs to fuck my dick hard. She is moaning and sucking the tip which her mouth Making me moan a hit because it’s the first time that has happened and it feels great. After a few minutes of this she asks for me to give it all to her because she has never seen a dick my size.

I then move back on my bed to get down to her pussy which is dripping wet. I stick it in and start going to town. Her pussy is softer and tighter than my gf’s and right away I can feel the difference and start to wonder if it’s not her but I really don’t think about it. She really gets into it with her pinching her nipples and moaning to me to give it all to her. I then give her all I have and she starts yelling that she is cumming and she starts shaking as her first orgasm shoots through her.

She then asks if it’s alright to ride me and I say of course so she basically jumps on me sending her tits jumping and ass bounces on my balls. She really starts jumping and slamming it all down to me so I do the opposite and when she goes up I slam into her ass. I feel a load getting ready so without asking I thrust into her and let out a large load of cum into her pussy and she accepts it wholeheartedly. Her eyes roll back and she shudders as she falls into the bed dripping cum.

I basically pass out from being drunk and the orgasm that I just had.

I wake up to the girl leaving early in the morning and I’m groggy so I really don’t say anything as I watch her leave. She glance back at my doorway and that’s when I realize that it wasn’t my girlfriend and that I just fucked and creampied another girl. My girlfriend comes home a few hours later and asks what happened after she left last night and I lie and say that I jacked off thinking of her which is a little kink that we both like to share.

I don’t know what I should do. Should I confess what I did or keep quiet about it.
