I’ve been dating my girlfriend for 3 years and we’ve had overall a very good relationship together and everything’s been solid. I also have a great relationship with her family, and I see them all the time since she still lives at home. Her sister also lives at home, and I’m not going to lie, I’ve always been very attracted to her.
She looks like my gf, but with more curvier features like a bigger ass and hips. I’ve also always gotten along really well with her, we seem to have similar interests and have great conversations about various topics. I’ve fantasized about her often but never thought anything would actually happen.
We’ve flirted a bit here and there and she tends to be a little handsy (nothing sexual, just putting her hand on my shoulder or back sometimes). However, nothing remotely close to crossing the line.
That all changed quickly this past weekend. On Saturday I went over to her parents house in the morning as I told her mom I’d help her haul some tree debris to the front. It didn’t take too long, and I went back inside to relax. My gf and her mom told me they were going to go shopping for a bit and that there was coffee boiling and some leftovers in the oven she had ready for me, so I should stay and relax until they’re back.
I knew her sister was still upstairs sleeping, so it wasn’t that weird as I wouldn’t be alone in the house.
Maybe 10 minutes later, I hear a door open upstairs and then some footsteps down the stairs. I turn to look once I hear “oh, dotoromotor, I didn’t know you were here sorry, I thought I was alone.” She was wearing just a bra and a thong.
Normally you’d expect someone to run to get changed when that happens, but instead she went along like nothing happened and pranced around in her thong in front of me for the next several minutes as she had her coffee and toast. As I said, I’m attracted to her and love her features, so seeing her in her underwear was a major turn on for me, and I started to get hard.
She walked around a bit more before saying “Let’s see what’s on tv, I’ll go get some clothes on first.” She came back down in what I felt was still very sexy attire. Tight yoga pants and a T-shirt that she had pulled up a bit in a knot so her stomach was showing.
She sat down on the couch right next to me , like her legs were touching mine kind of close. I felt super uncomfortable but also turned on still. I had on gym shorts and still had an erection, which I think was fairly obvious to notice if she looked in that direction.
She put on Friends, her favorite show, and the second episode in, she laughed at a line and sort of patted my upper thigh area while laughing. Well..this just happened to be right where my hard dick was positioned, so her fingers actually were slapping my cock.
She immediately looked down at my tented shorts and said “oh, I’m sorry dotormotor, I didn’t know what I was touching.”
I’m pretty sure I turned beat red and just sort of mumbled “it’s okay.”
She then goes “Did walking around in my underwear cause that? I know you like checking out my ass, so it’s okay if that is why you’re so hard.”
I’m no idiot, at this point I knew she was escalating things and I was okay with it, so I was blunt and told her it was and it’s been like that all morning due to her.
She smiled, moved her hand up my shorts and took it out. She told me “my sister is lucky.” And then started stroking it for a couple minutes, followed by her putting her mouth around it. I should note that my gf hates oral, so this was the first BJ I’ve had in like 5 years, and wow did it feel good. I told her that her sister never sucks it, and she said “you picked the wrong sister, I’d suck this every day.”
I was insanely turned on and honestly had no regrets while this was happening. Well, things escalated even further and she climbed on top of me and we had sex right there on the couch.
This was the first time I’ve ever been unfaithful, and man, instantly after cumming, the regret hit me hard. I immediately felt panicked and started telling her how we shouldn’t have done that and I just ruined everything etc etc.
She promised me it was okay and she wouldn’t ever say anything. She seemed to not feel any regret and told me we could do it again whenever if my sex life with her sister isn’t good.
About an hour later my gf and her mom came back
home and I felt I did a good job at acting normal, but a couple days later and the guilt is just eating away at me.

You seem racked with guilt. Good thing you posted about it two days later.
Just fuck her sister again
If you’re still with her in a few months, the holidays should be interesting.
She knew exactly what she was doing. And she’s going to do it again. You had better be prepared to either bury your cock balls deep in her pussy, throat and ass OR never touch her again.
My guy, we all know that your gf’s sister knew what she was doing. Lol. What’s done is done, however what you decide to do after is what will seal the deal.
You must fuck that ass at least once, don’t you think?

Oh boy, going from lust fueled euphoria to post-nut guilt was the worst. Give it some time, and the 2nd/3rd times get a little easier.
If a GF does not do things you want or is normal in bed before marriage it does not improve with marriage usually. It gets worse. I married one who is would not do things when we were young. Over the years it got worse. Sex less than once a month in 40s. You have to weigh everything else versus unsatifactory sex life. Breaking it off before marriage you guys just lost time. Divorce is messy and add kids it becomes even worse. You are young. Don’t know about the mental state of sister to come on to you and state of relationship that you went with it. Guilt is one things, but the fact the sister could turn your head so easy says a lot about your relationship.
I can’t help but wonder how the mom looks if both daughters are hot.
> She put on Friends, her favorite show
Pretty big red flag if you ask me.
Well I can tell you one thing if she ever argues with her sister just know she’s going to spill the beans. I can almost guarantee it
tell your gf before her sister tells her first. your gf deserves better.
If you feel guilty, you’re gonna have to own up to it and be honest. That, do it enough and you’ll stop caring. But honestly, you should break up with your girl. I’d say possibly try to get with the sister, but just know that’s not gonna work out well either.
