One of my friends can’t keep his hands off my girlfriend.

Show him her tits!

Have you thought that she probably knows that you showed him the photos and videos and that this may be her way of paying you back?
She is probably waiting for you to make the next move. She may also be showing you that she would like to experience a threesome with you and your buddy, which doesn’t necessarily mean that she doesn’t care about you. Just that she needs a bit more excitement.
I think you showed him the photos because you wanted to make him feel jealous of the great sex that you are getting and unfortunately for you it worked and now he wants to share the fun. Now that you have opened Pandora’s Box, you need to see how it plays out. Decide how far you want things to go. Set the limits with both of them and have some fun together.
In my experience there is something really special about watching your girlfriend perform with another guy and then joining in. It really is an awesome experience if you can handle it.

Works like this- Ifyou can't stand up to him, she is going to go to the alpha. she will enjoy and desire him. if he respected you, no way in hell he'd do this. depends on what you want- do you want to see it happen? you showed him the pics. you let them hang out. you can challenge him and make them do it front of you- hey dude you saw her tits, pull your pants down... and go from there. Or you can really want it to stop- take him aside, away from her, call him out and tell him it had better not happen again or you and him are done. It does not have to be a physical threat. If he does it again, he has made the statement loud and clear about your relationship. You can tell your gf just that a to why you are not inviting him out any more. if she chooses to keep seeing him- she had made her statement to and its time for you ditch. you can only control what is in your life, you cannot control their desire for each other. it wont be the first time your love desires another, but if she can't control it, she is not ready for a relationship. how old are you guys anyway? sounds like 16 yo behavior.

Not sure if you're trying to elicit sympathy or solicit advice. You've come to the wrong place for both ! You have an appalling lack of good judgement, and they ( and, you ) have the morals of a mud shark. It's always laughable when such bottom feeders look around themselves and go, " Ewww, it's muddy and nasty down here ! " Comes with the territory you nutless needledick !

Your fault for showing him, but...Put a stop to it, now. My gf is very beautiful, sweet-smiled, sexy, and guys just..Go to her. Guy I know from the sports bar I to go has, twice, come over to us and hit on her, massaged her shoulders, and, the first time, she was on pain meds for her back and mixing drinks (even though I told her don't), and not in a good mind frame, sat on her side, two seats from me, and gradually started leaning into her and putting/resting his hand on her upper thigh. The fact that she did nothing about it the first time concerned me, but, I did get her/us out of there, since she was getting sick and did end up yucking in my car.

That second time, though..The shoulder massage, was my last straw. He started, she didn't refuse, and I looked at him, dead-direct, and told him "Fucking stop now", and he did. Then made up some excuse about thinking she was someone else he knew, all this lying shit. What bothered me more was that she sat there and soaked it up (we did talk about that a little later). I do her shoulders, and it's..Not there, too hard, this and that..HE does them, and she's into it. We don't go there often, by choice and b/c there are two other places we go that we, as a couple, like better, but anymore..I'm careful of what night we might go (this guy works nights), and we get a table, not the bar.

That first time pissed me off a bit, too, since, before she started getting sick, she was flirting and eating up the attention. Weeks later, during a back and forth, that night came up, and I told her "It looked like you were going to fuck him right there on the bar". As much as this guy is handy (with a lot of women, mind you), she was equally at fault for accepting it, until I had to step in and stop it. I do blame her, both times, as much as I blame him. It hasn't happened since, and if it ever happens again, she's walking home or getting whoever gets their hands on her to pay the bill and take her home. I'll walk out and drive home.

Well played my friend.

He is checking her boundaries. If she doesn’t stop him at the shoulder massage, it’s only a matter of time before he is sliding his hand inside her top and massaging her tits. Maybe he already has when your back is turned, or you are away at the bar.

I rarely leave her if we're at the sports bar, and that's why. If the same guy is there, I have no idea what goes on even for the brief, fast piss I might take. The shoulder massage wasn't long b/c I put a stop to it. He's just one of these guys who thinks all women want him, whether they're married, single, with someone. And he knew I wasn't buying the whole "mistake, thought she was someone else" crap. Was a little surprised when I so directly told him to fucking stop.

I work behind a bar and I see plenty of this, especially towards the end of the evening when everyone has had plenty to drink. I a boyfriend distracted talking to his friends and his girl standing alone nearby. A guy comes over and says something in her ear. They both look over at the distracted boyfriend and the guy runs his hands over her body. She doesn’t attempt to stop it. She makes her way towards the restrooms and the guy follows. Boyfriend still hasn’t noticed. She returns alone about 20 minutes later. I have seen this happen on more than one occasion. Girls love the attention and if you are not providing it they will get it from someone else. The element of risk adds to the excitement for them.

I gave her tons of attention, and she ate it up. I did it because she loved it, and, speaking as a guy, to give the message to other guys, lay off, she's mine. She's only left to go outside for a smoke, and I can usually see her though a window if I don't go with her. I have told her a few times to let whatever guy she was flirting with (or perceived to be) pay the bill and get you home. That did seem to get a good response from her. Told me one night when we were out "I know you don't like when I talk to guys"..Well, DUH...What guy would?

Drunk or not, you made a big mistake showing him the pictures, You also mentioned videos and its my guess that these are not just pictures of her naked, but fucking and sucking as well. He has probably been jealous of your hot girl for some time and now you have shown him what she is really like in bed, he also wants a piece of the action. He probably thinks she is up for it after seeing her slutty behaviour. If you don’t want to lose her to him, why don’t you suggest a threesome with him? Then everybody is happy.

I am guilty of this. I have no idea why a couple of my friends allow me an occasional grope or kiss their wives. They sure dont seem to mind and my friends really never pay it any mind. Hell I wish either one of them would do the same to my wife who is one of those that is usually the prettiest one in a room.

I think this is hot, I wouldn’t be jealous if I was there and she didn’t mind. It’s exploring new boundaries, which is only going to make fucking her all the more exciting.

This is not so unusual; there was a guy I used to play football with, who admitted that he got off on watching his girlfriend with other guys. He used to bring her to the away games and she let us play with her boobs at the back of the team bus while he watched us over the seat in front.

Put em in his place, or you gonna lose her haha.

You fucked up. Never ever share things like that because it won't stop there. It's not going to be the tits, but his dick parting her lower lips and you are doomed. Once she has his child in her uterus you are fucked over forever. Never share pics.

Might as well have a threesome now and get some of the action out of it.

I do that with my friends girlfriend, basically i want to fuck her!
he is the same

Sounds as if you will be looking for a new girlfriend soon. This girl is not committed to you. Everything is wrong here.... her letting you take videos and you showing them to friends.
