The best way is for all you to get together and talk about it. You have to set ground rules and make sure all are in agreement. If you don't someone could get upset and all is ruin. Have fun!!!

i have no idea but i wish you luck

Step one... Invite me!!
Step two... Sit back and enjoy the ride....



haha....but seriously...You would be soo surprised how these things ride themselves through...doesnt take much effort...Just requires one person to kinda choreograph some of it..

Start with kissing and touching....start with the removable of some clothes...oral sex...Switch up who's licking who... start with some masterbation...and you will be surprised how the rest figures itself out...

In my experiences, you should have sort of a casual conversation beforehand, maybe not right before the actual act, but just sometime beforehand so you can figure out what everyone is comfortable with.

To avoid any awkwardness, we have usually started the night just hanging out, listening to music and drinking wine. Things sort of naturally progress after about 3 glasses apiece, lol. Good luck and have fun!

i'd start with booze, but then again, i have a history of botching such things, lol

but seriously, have fun, and just keep the lines of comunication open on the subject to avoid misunderstandings
you'll have a blast

Me and my girlfriend are in this same situation. I think it all depends on the mood set but it would be best to go out and loosen up first. Whatever that involves for all of you (drinks, sexy movie, porn anything really) and then let your instincts guide you. If its someone you know (and it sounds like it is) then that'll make it real easy because you can straight up ask beforehand what kinds of things get her in the mood.

Well besides that your boyfriend is a lucky fuck.. I would have to say that no drunken threesomes! Way to crazy to handle the first time. The best time is the morning or mid sleep.. the distorted feeling is pretty cool..lol

Well you all three go to you room or couch, and you should, start it out. Kiss her, then him, then she or he will kiss the other, Start taking his clothes off then her, and let him take yours off. Have fun!!! Not sure if this will be good for your relationship. Try not to get jealous if he makes a sound with her, or if she really enjoys him and him her..

alcohol always helps but yeah i think you should talk about it before hand just to make sure you know where everyone stands
xx

So, wait...not only does your boyfriend get to have sex with you...but now he gets to have a threesome with you and whom I am assuming is another gorgeous girl? Man...some guys get all the luck!!!

And it looks like you've received some really good input here. I agree with everyone suggesting keeping those lines of communication open. The one time I did this, it wound up ruining my relationship because we never fully discussed it beforehand. It just kind of "happened" one night...

Anyway, I look forward to hearing how this all goes down!!

3 green lights = go for it! Just let it happen spontaneously! Have fun!
