I have not dated anyone close to my age.  But I think the issue is with establishing and understanding each others' boundaries.  If one person is secretly hoping to find a long term life partner and the other is just seeking nsa playdates, you have a problem.  I don't think the lack of a big age gap makes it any easier or harder, just talk it out so you both know you're on the same page.

I get it. You can see this developing into something "real."   But it's not. At least not yet.  She joined the site looking for sugar. You negotiated and agreed to a sugar arrangement.  So for now, live the arrangement and enjoy it.  

 
Consider this from her perspective IF you try to wrangle this into a civilian dating relationship after one date.  You will probably look like a "salt daddy" who wants the juice but won't pay for it.  

 
If she wants to "blur the line" she will let you know. Or maybe she won't. But I will suggest that you wait for her to make some gesture before you get your hopes up. In time, she may offer to stay for longer dates. She may offer to go on (expenses paid) travel with you for no additional allowance. She may want to see you for non-BCD and/or non-allowance dates. She may even suggest that you transition to a traditional relationship with the desire to be exclusive and perhaps in the hope of developing or advancing to BF/GF or even being open to marriage options. But that's not going to happen in the immediate time frame.  

So go forth and enjoy your balls deep experiences with a woman who checks all your boxes and rings all your bells.  All arrangements end. But endings can come in many flavors, including moving on to someone else, or moving forward with her. Time will tell.  

 
Life is good

Are you asking should you continue to keep paying her?
Or more so, isn't it great when there's not a 50 year gap? lol
Trust me, there's not an older guy here who wouldn't have liked to have enjoyed a super model when he was younger
But the reality is, he's not going to now bc of the cost of such an arrangement.
I'm able to, but yeah throwing a couple grand her way is a bit irritating.
In any event, I'm jealous and I would think most of the guys here would be equally so.

If you are paying her, don't fall in love. She's there because you are paying her.

I hope it doesn’t go the way it sounds like it’s headed

I've been burned pretty hard by getting very emotionally involved in a SD?SB relationship.  And she was far older than the average SB.  However, there were some clear flags that I overlooked.  I would take it one step at a time.  If you really start to fall for her you need to really see who she is.  

Why is she still a SB at her age?  If all she knows is how to look hot for you, then get your kicks out of it and run.  She has decades of experience of being paid to look hot and that's all she has.
Would she want a real relationship or be completely exclusive to you?  If she's not willing to only see you, that's a clear sign.
Is she only looking for FWB?  If that's in her profile.....  At her age?  WTF?
What's her family, kids, marriage/divorce situation?  And really find out, not just what she says it is.  There's always something fishy going on with much older SBs.  Multiple divorces, kids, meaning very unstable.  

In my case, she swore we were exclusive.  She had a job that included 'travel'. It turned out her 'friend' was her real boyfriend. Her travel for work was her seeing SDs in other states.  My advise, be very careful.
