18 22It's not technically incest, because they aren't blood-related, but it is still taboo. And yeah, he cheated on you, who he cheated on you with is really irrelevant. Dump him. He can always bang his stepsister again if he gets lonely.
That is GROSS
You have to remember that a bond with a step brother or sister grows over time. Its not like a real sibling bond. So really its more like the stages a friendship goes through. We all have a friend that we have gone through the, damn they are hot all they way to the feeling of deep caring or hate.
Id be more concerned with him still having the sexual attraction with her now then when he did before
Not that simple I mean if they grew up together then it's gross but if they met as adults it's fine
The only problem I see is, you got cheated.
There is no relation between them so it isn't wrong, the only reason why people think it is wrong because the are hung up on the word "sister". it isn't like he cheated on you with her
Wow you need to dump him
Discovered my new partner had a secret two year relationship with his non-blood step sister. Kept it secret from his whole family and even cheated for several months on his long term ex for her. Initially I was able to see it wasn't actual relative but as time has gone on the constancy of her in his life (comparisons/fact his parents love her/talk about her/she is around) has really broken me. He thinks it is all my issue and can't see how it could affect our future. We've talked about marriage and kids but she is getting married now too (they broke up two years ago after their two year relationship) and it feels as though we would be compared by his whole family and then our kids would be too. They don't see each other nowadays since they came out to the family and the relationship doesn't work, but knowing she is always nearby and current at his parents place really makes me unhappy. O thought it was worth posting in case you hadn't thought any further down the line. They never ever go away like most people's exes do.
If my step sister is hot then I would so fuck her also.
I would be VERY careful. My now ex-boyfriend cheated on me... with his stepsister. They were actually raised from childhood together, so it's really disgusting to me. In my opinion, it's just as bad as if it was blood related. I was so disgusted with it. I was willing to overlook it when he told me it happened in the past, but I realized it was a mistake, because it was still going on. There will always be that attraction and temptation there, especially if she's still in his life.
Its not incest but it is inappropriate.
Not incest but it is wrong. To cross that line even if you're not related is just ick. That just starts family drama. Only way I could phantom someone doing that is if they were 100% in love and wanted to be with the other. Seeing how it sounds like it didn't work out, it shows a real lack of control. I don't think sex would be worth the drama and plus it's gross. No one likes to see their others ex. What he did is have to subject whoever he's with to be around someone he's fucked. Awkward.
even though he did it before yous were together its not okay. and he still makes time to call her? dump him asap. its not okay, its so wrong! omg he needs serious help! do you know if they still have sex or what?
I ask him on the phone are u thinking about having sex with her again? He's like " in all honesty if we break up.. I wouldn't mind fucking her. I find my step sister sexy so yeah" and I'm on the other line like... o. O
It's not incest. It's not even technically incest.
If he was dating you at the time though, it's cheating.
No we were not dating at that time
