My friend "Jane" and I used to date for a few months and decided we weren't really a good fit for that. But we had amazing sex, so we stayed friends with benefits.

She is bisexual and got an amazing girlfriend "Beth" a few months ago and they are super in love. The three of us have hung out a few times and we ended up hooking up together, the three of us, a few times. It's been really, really fun.

Here's where it gets challenging. Part of the dynamic Jane and I have is DDLG. I call her "baby girl" or "princess" (etc) and she calls me "daddy" and we do some very light roleplay around that. Mostly she just trusts me to be kind of paternal and take care of her and make her feel safe, rather than anything super age play related. It's a dynamic that is really easy for us and fulfilling and super hot.

Jane has been a little... um...protective about how involved me and her girlfriend can be. She doesn't want me and Beth to do anything DDLG related (which is totally reasonable and understandable), other than me being allowed to call them both "good girls". She also doesn't love the idea of me kissing and penetrating Beth, although in the heat of the moment she does allow it sometimes (she will just take control and tell me to fuck her or whatever).

I'm 100% fine with all this because my number 1 concern is everyone staying happy and having fun, and I honestly just feel like I've won the lottery so I'm not going to complain.

Whenever we are done, we always talk about how things went and adjust our boundaries and expectations if we need to. It's working really well, but one thing that has come up a few times is Beth can feel a little bit left out since Jane and I have free reign to do whatever we want to each other, but Beth and I are more limited. Especially with the DDLG stuff being mostly off-limits between Beth and me, as Beth has confessed she finds that dynamic hot and likes calling guys "daddy" and being called "baby girl" too.

So the advice I need is, what are some scenarios or dirty talk I (or we) can do to make Beth feel more included within the boundaries we've all agreed to? One that I've thought of that we agreed to try next time is Jane is my Baby Girl and Beth is her friend. So she's included in the dynamic, but she can't call me Daddy and I can't call her Baby Girl or anything like that. So I guess I would say things like "baby girl, your little friend is sucking daddy's dick so good" or whatever.

What are some other things we can try?
