  • My suggestion for anyone considering threesomes are:
    1) communicate with each other well. The less you argue/fight over issues, and more you can just talk and work the out, the better.

    2) neither of you be the jealous type. If you say yes, and then you all get in bed, and he touches her, and you get upset? That's not his fault. Resolve jealousies, or just be low jealousy people. Otherwise, you even see him smile and say hi to her, you might start thinking things are happening behind your back. Jealousy is ugly.

    3) Be absolutely positive he has no reason to be possessive/jealous with you.

    4) pick a third person you both want included

    5) be sure the third party is someone you can both trust.

    6) Don't do it to make your partner happy. Do it because you want to share the experience with your partner.

    Those are my suggestions no matter who is in the threesome.
    Your sister?
    Some people might read that and freak out over it. I'm not one of them. As long as you trust her, trust him with her, and you don't mind the idea of doing it?
    Give it some deep though, but if you consider it, I don't think that's a horrible thing.

    But... if you don't trust her? Or don't trust him? Or don't trust yourself to not be jealous even if you know you can trust them? Or even if you know you can trust them unconditionally, but you DO NOT WANT this?
    Then don't do it. That simple.

    • Outstanding answer. You took the words right out of my mouth.

  • Wait a minute. The threesome would include you and your sister as well as your boyfriend? And you're wondering if you should do it? Okay... First, assuming that you are all of legal age (18), and all of sound mind (except, of course, you, for asking the question in the first place), I would not advise getting naked with a member of my own family even if we never actually touched, and the guy was just the middle of a fun little daisy chain. There are so many ways that this could go south, other than the obvious. One: State laws vary in their opinion of such activities. I would make sure I wasn't going to have to register as a offender under some weird incest statute. Two: There is always the odd chance he might think your sister ______(s) better than you do. How do you deal with that? Think there is a chance for a bit of jealousy or worse? Three: Do you want all your friends or all of his friends to know about this because dude is gonna brag about this (guaranteed) and your sis will probably talk to her bffs at Sunday school. So good luck with your new found celebrity. Four: If this is your idea, it's a bad one. If this is his idea, he's hot for your sister. Don't do it. Dump him. Stay out of sissy's bloomers. And stop watching so much porn.

  • I hate to tell you but 3-somes are not all that they are cracked up to be. People make them out to be so much fun and that they are really hot to do. But in actual fact the single person male or female has to divide their attention between to other people. So how exactly is that fair...

    • I n ny girlfriend had lots of threesomes both mmf and mff n never affected us. Still going strong.

    • Some people like it others don’t.. plain and simple, I myself that tried it and did not like it, but then again it could have been with the person I was with at the time

    • Probably. Our rule that we stick to is nobody is neglected or given less attention etc... its tempting for the guy in a ffm to concentrate on other girl n girlfriend to concentrate on ither guy in mmf so we lay down simple groundrules n so far so good.. if ur ever in dublin look us up (wink)

    • Show All

  • Dont do it. Even by asking this from you he is an asshole. He doesn't respect you at all can't you see? I know probably now you are blind with love but this guy is up to no good trust me and leave him asap.

  • If you’re serious that’s basically incest and also it makes it seem like your boyfriend is only with you for your sister.

  • absolutely not... practically incest and your boyfriend is weird asf

  • No, tell him no and if he presses the issue, dump him. You'll never look at your sister the same. Every Thanksgiving is going to be awkward. "Why are they always staring at each other?" You can't shake that off. Don't do it.

  • Chuckle. I did that very thing back in the day. All I can say is that IF you are going to have a 3some, it’s the type least likely to be hurtful to anyone. Hey, the 3 of us are still friends after 15 years

  • Not a wise thing to do. It's fraught with possible problems. If issues or problems arise, you sister is not someone you can just put to the side, out of your life, as a friend or acquaintance can. If your sister marries or has a long term relationship, her SO will always know that she got naked with your boyfriend and fucked him. That could lead to some awkward family situations. That could lead to some jealousy and real problems later. Also, what if your boyfriend started showing more sexual attention to your sister, than to you? And other problems could easily happen.

  • Is this a real question?

  • It is legally and rightly incest. But if you are identical or siamese twins, it would be like having sex with yourself, so you might get away with it.

    Unless you already have a sexual relationship with your sister, I suggest you not do it.

    I think there was a set of female siamese twins who had sex with their boyfriend and had pictures of it uploaded.

  • Absolutely not. It’s incest, and it would be immensely awkward between you and your sibling and would damage your relationship. I would also consider dumping your boyfriend— him asking for your sister is disgusting. Please don’t.

  • If yiu dont mind incest.

  • NO!!

  • No. It's sad he doesn't have enough with just you. It fucked up he wants to do your sister too. He's been watching too much porn. If you're serious about this relationship, don't do it. From that moment on all your family events will be awkward AF.

  • Uhhhhh... yeah no. No... No... No...

  • Ew not cool

  • Absolutely. And give your boyfriend props for me if it happens. Haha

  • Of course you do it. As long as all three are up for it then yes do it

  • No! That's incest!

  • ewwwwwwwwwwwwwww nyet

  • hahaha... sure. Go for it.

    • Yeah my sister is pretty cute

    • I'm sure she is. I've seen plenty of vids where all three people enjoy it and it's a blast.

  • No way

  • If this is a serious question, Leave him. He clearly has one intention with you.
    Girls are so afraid to Leave a guy.

  • that would be weird

  • if he specifically ask for your sister you need to be concern
