Okay listen i am going to a have a three some this weekend w/ my girlfriend and her dorm mate.
i have never done this before.
tips? stories? experience?

It'll probably end your relationship if you don't do it right. Act like you don't give a damn about her dormmate; pay attention to your girlfriend. Maintain eye contact with her as long as you can. If you give a damn about the relationship, don't focus on the other girl, as hard as it may be. If not, then lewl. Give 'em hell?

In my experience, I was the 3rd wheel while they focused on each other. I hope yours is similar :)

My biggest suggestion is to RELAX. Using whatever substance (legal of course) you can. And enjoy it, because unless you're a F*CKING liar like most folks, you'll only get to do this thing once or twice before it comes down in a pile of steaming shit like Gman said.

Yeah what Gman and Dirk said, just relax man and pay more attention to your Gf than the other girl, ofcourse if you
get them to play around with each other that makes it alot easier for you :)

Starting with massage is a great way to get them to relax aswell and it also makes it easier
for you to get them into the whole girl on girl action ;)

Oh and for the love of god enjoy it man cause this is gonna be a memory for life no matter which way it goes :P

Shiiiiit son, I don't have any tips, but I want the details after this is all over with!

And don't forget to post the video

F*CK yeah dude, get the whole voyeur thing going on with the hidden cams and shit!

don't pee on them...

He's right. It may excite them the first tmie, but then they will want something freakier and freakier each time (think 2 girls 1 cup.) It's a slippery slope. Pun very much intended.

If anything make sure you and the dormmate both focus on your gf, make it all about her and you'll be fine. Don't try to satisfy the dormmate, she's the whore in all this and needs to be treated as such.

Pics, vids, and a well written post are mandatory if you expect to maintain your membership in n00b. Maybe not but it would go a hell of a long way as far as my respect for you as a man.

Utter damnation...some guys have all the luck.

Pics/Video or it didn't/doesn't happen.

Ive been down this road, If you truly care about your lady, do not even do the threesome. If you do decide to go through with it anyway, the above suggestions are excellent, maintain your lady as the focus.

When my lady and I had our three way with a lesbian friend of hers, I made my lady orgasm a couple times and went to move on to the other young lady(about to penetrate), unfortunately seeing ANYONE other than herself getting my attention drove her crazy, My lady started trying to fight her friend, I did not penetrate her friend, I took a step backwards and i said "Not everyone involved in this is comfortable, I am sorry but we will have to end this exploration.
Whats really funny is that after her lesbian friend played with my dick , SHE WENT STRAIGHT. LOL 2 weeks later we saw her again and she had a boyfriend.

All in all, Nothing bad came from it (it would have escalated if i didn't stop it), In fact i got a hot young lady liking the dick, I think that is a win for men everywhere.

Stop talking right now, because I don't want to feel any worse. Sigh...why do I never get to play with a lesbian and my girl?

Awe! poor reborn! lol i feel ya! but im young so i have PLENTY of time :)
