I just had sex with my step sister?

so a few months ago my dad remarried with this lady who has a daughter thats my age, 18. my dad and his new wife have been living together for almost about year and since they got married I've been spending more time with my dad. since I've been living with my dad for a few months now i really got to know my step sister. she's always been really flirty with me since we met. so anyways a few days ago my dads cousins came to visit him and they were going to stay at his place for about a week, they needed a room to stay in so my step sister offered them her room and my dad decided she could stay in my room with me. before we went to sleep we had a pretty long conversation, we ended talking about sex. i told her I've only had sex once and she told me the same. she kept telling me how she wanted a fuck buddy. in the morning i woke up to her touching my morning wood saying "having a nice dream" then waking out the room. later that night i was in my room watching a movie and she had just gotten out the shower. my dad and step mom were downstairs with my cousins having a good time, playing board games and drinking. my step sister sat down next to me and told me she was sorry she touched my boner, she told me the reason she did it was because she hasn't had sex in a while and its driving her crazy. she put her had on my lap and said "i just need someone i can have sex with". i was surprised but before i could say anything she leaned in and started kissing me. we both started to touch and grap eachother. taking off clothes. and before i knew it i was having sex with my step sister, it all happend so fast i couldnt think straight. she started moaning but because of the little party going on downstairs they didn't hear her. i ended up cumming inside her, i freaked out but she told me she was on the pill. after that we talked and she told me she wanted to keep this sex thing going. i dont know how i feel about this. i feel that its bad but also want to have sex with her. is this bad?

  • Well... since she isn't blood related to you so it's not TOTALLY gross (since you aren't going to inbreed if something DOES happen)... I wouldn't suggest to keep going because once your parents find you two out, they're going to freak and they will probably have some major consequences for you and your sister. It's up to you if you want to keep doing it but my opinion is stop. Once you have a girlfriend, she's not going to be too happy if you were having sex with your step-sister and depending on how your girlfriend is, she may dump you.

  • No, the same thing happened with my step brother and I. We were fucking buddy for about 6 months and it was really fun.

    • OKAyyy that's not right

    • @mattl338 we met at 16 and 17 and were attracted to each other oh well. Enjoyed each time he was in my guts

    • Okay I did not need to know that and you’re sick in the head

  • Well there's no blood relation so as long as both of you are comfortable than go for it.
    Just keep in mind that you both are still technically family which can cause problems since inevitably either you will try to find another girl or she will try to find another guy since I doubt you two will marry.

  • "oh sorry I touched your boner" in badly imitated female voice,"I just... haven't had sex in so long..." I had to laugh here

    • LOL same. I had this thought of Dakota Johnson saying that in her "sexy" voice and started laughing.

  • wow, thats crazy, go for it

  • *slowly claps*

  • In my opinion, there is nothing wrong with you having sex with your step sister because she is not really your sister and you are both at or past the age of consent. I would suggest you not have sex with her at home because you might get caught. I would also suggest you keep this from all other family members. There is no rule that says your people have to know all of your business. However, if you continue to feel guilty or bad about it, do not keep having sex with her. That is a warning sign that you have made a mistake. Never ignore your conscience. However, from my point of view, you have done nothing wrong. Take care.

  • She's not your actual sister so whatever.

  • Meh, still a better love story than twilight.

  • So this seems like a very Japanese anime script

  • I pray this is a troll

  • There is nothing wrong with it.

  • If only all girls were like this but I would prefer it never be my step sister.

  • It's bad... But whatever... Bad decisions are fun! :D

  • I mean it might get weird, especially if you two get into a fight or get caught or fall in love. I guess congrats on getting laid. I don't know man to be honest.

  • Trolls be trolling

  • This sounds way too convient and made up.

  • I think I would be playing... a lot

  • You aren’t related by blood, go for it. Marcia and Greg Brady would approve.

  • Plzz b a troll bro

  • trolllllll

  • She's only a step sister go for it have sex with her

  • As long as you both like it and she's a stepsister and it was consensual

  • A family is a family. Even if its blood related or not she is still part of the family. Respect every woman like your own mother, discipline yourself even if its hard., its hard to fight temptation especially if its good on your side but remember every wrong decision comes with a negative effect. Remember, repentance is always at the last.
