Ethically Correct?

[doktored]

Right, this should be a happy time of my life but it isn't. I just had sex with my new girlfriend (we've been going out for a couple weeks). Im upset and confused because it didnt turn out how I wanted it to. Basically, you may remember I was bribed because my sisters stepbrother was getting called tumour dick, well since we sorted that out we have been real close, up to the point where I have been showing him pointers/techniques on masturbation. I just couldn't help but think how similiar he was to me. Anyway, today I was giving him pointers on condoms, safe sex you know what it's like. So, afterwards, it got to the point where we started wanking, and in comes my GF. Instead of going into a blaze like I expected her to do she starts to strip and in the end it turns out we are all having sex wearing the, convenient, condoms.
Anyway, my question is that is it ok/ethical for a step sister/brother to have sex with one another. Also, I think the main reason my gf's brother was involved was mainly because my gf didnt want her parents to know. Should I tell her not to bother?

Well they technically are still brother and sister, so yeah thats wrong. But by science they are not brother and sister. If I had a hot step-sister, why not?

i would strongly suggest not to get involved with step bros/sis. even though they aren't blood relatives, it would make life around the house and stuff very awkward if you got involved with them sexually. i just wouldn't do it!

[Oblivion]

Well I dont believe its incest since they aren't technically related, but it still could cause major family problems
I would advise keeping sex between yourself and your girlfriend from now on.

Not a good idea. I'm sorry.

Wait, I'm confused here. Are you saying your g/f and you and her step bro had sex? And you're not sure if this is wrong? Are you serious?

Let me be real clear here, Clarkey. I think there's a lot wrong here, b/c a lot of really bad feelings and stuff can occur (as they seem to have already) when you and your g/f have sex with someone else, unplanned, and with a family member, no less. If it's technically incest or not is irrelevant. It's potentially very messy. She's your g/f, if the 2 of you decide to have sex, that's between you both. Sex is very personal and very intimate (or at least it's supposed to be), and having someone else join you sorta interferes with that, unless it's a recreational activity who's participation you both agree on. And, if it's someone she lives with, then it's doubly complicted. If things get stirred up emotionally, as they often do with sex, there's nowhere to go to get some space from that person.

I do remember your last post concerning your step bro basically blackmailing you into doing sexual things, and if this is all true, i think you've got a big problem on your hands here with sexual things and the way you guys handle those urges. At the very least, I think you need to keep sex out of that relationship, as it seems to be causing a lot of unnecessary and potentially very complicated problems in your family.

We've chatted, both my gf and her bro have thought about problems that may occour in the future because of this. We've decided to keep things secret, sex will be between myself and my GF now, although I will still masturbate with her brother and give him tips.
