Gf going away with lover for the weekend (fist time)

This is my first time writing on here. Suppose I'm looking for input off other cuckolds and there experiences on this specific topic.
Our relationship started out as a cuckold one from the get go. I already have very profound feelings for her and feel so lucky to be with her. She currently has a lover, who she met after me. it's only a new relationship with him but non the less he satisfies her in bed more than I ever could (I'm only 5 inches and very thin) and never orgasms with my little thing. This weekend she goes away with him. I've never seen her so excited and wet when he rang up last min to surprise her.
Anyway I'm so excited at the thought of her with him looking and acting like a real couple and getting really close to him while I stay at home (horny as hell). Part of me wants her to get closer to him and tell me how amazing and how much better he is then me in the bedroom, as a man and that she can't wait to see him when there not together. Of course the usual thoughts creep in of jealousy and not wanting her to leave me for him but these are completely normal feelings to have from what I read.
Has anyone had the same experience and is there any advice you could give me? I want this relationship to evolve and develop into a deep cuckolding one.

Is there anything extra I can do? Things I can say to her to show support? Let her know she's in charge and make it obvious I'm her subservient cuck always there for her however things turn out?

Did she read your post?
If not she have to do it!

She knows I'm on here but has not seen the post no.
You think showing her is the best option?

Can you tell us more about her - looks, age, how confident she is etc. What's her name? Could we see a pic? One thing you should definitely do is help her get ready - prepare herself and pack her bag. Would love to know what she's planning to wear.

She's 5ft 4, brown hair, brown eyes, slim with the most amazing ass I have ever had the pleasure of seeing! The kind of figure that lingerie is made for! She's 25 and quite new to the whole cuckolding scene. She's introvert but also confident. I wouldn't be comfortable putting pictures up. We keep this side if us very private.
She would definitely love me to get her ready! She wants me to paint her nails for her
I get really turned on by offense and before I even told her it turned me on she told me my penis is too small and not up to the job (we still have regular sex) she never cums with me though. Puts me more in the cuck zone so it's something I quite like.

She wants me to get a cyber skin penis extension so she can feel something. Anyone know if they're good or not?

Just a quick update! She had an amazing time and told me when she got back she's crazy about him! Apparently they pretended it was their aniversary and got a free bottle of wine and an upgrade on the room. She was telling me she loved playing the part of being his and had feelings in her stomach she hasn't had for a long time. Il be honest it made me so hard when she told me this but I still get the pangs of jealousy. One thing she seems to enjoy the most is telling me how much better sexually and as a man he is. I'm not sure if she keeps saying this cause she knows it turns me on or if it's just totally true! either way things are moving forward

Well he turned out to be a total idiot so she's back on the search! Date all lined up for the 28th already. He seems better looking, in better shape and not brain dead so I'm hopeful for this one
Don't know his size yet but due to how small I am he can't be any smaller (her words). I think I get more excited then her sometimes.

After 8 years together my girlfriend went away for a weekend with a new fuck buddy (the 4th fuck buddy in total), several weeks later she left me for him and is still with him a year on

Few questions.... How come after 8 years you never got married? Is that something you wanted to happen?
It's not something I'd want to happen. I do believe you can fall for more then one permister and stay together. It just takes a special type of permister I suppose. Do you still serve her though? Because that would be hot if she's with someone else but still keeps you informed and makes you preform duties for her.

Me and the gf are going away this weekend she told me she had a surprise for me for when we get there, but she couldn't hold it in any longer and told me she had bought the feather sex aid (makes your penis feel longer and thicker) and also...... The smallest chastity cage she could find . She's not sure how long she wants to keep me locked up but definitely when she's with others she wants me locked up. I have a habit of masturbating but not letting myself cum and I could do this for hours! Does anyone else do this?
I can't lie I'm very turned on by the thought of chastity Im hoping it's something she really gets into and who knows how long il be locked up at her mercy. All very exciting.

If she needs some encuragement.

Let me have her email.
it might be painful

I take it your a bull George? You been with many cuckold couples?
