I need some advice! (Sorry for the wall of text, I didn't realize how long this was going to be!)

Okay so for context, a little over a month ago I met this woman at a bar. She's about 15 years older than me and SUPER pretty. She started flirting with me and yea I was super into it lol. So we like chatted, she bought me a drink, and we ended up making out a little, and at the end of the night she was like come back to my place, but I had like a complete panic attack for no reason haha. She was super cool about it, we exchanged numbers and she was like don't worry at all just go home and let's chat later and see if anything happens. Like she was really sweet and nice. So yea I went home and ngl I was kinda sad I didn't go lol. She even texted me later and was like I hope you got home safe!

So I texted her the next day and was like I'm so sorry I just sorta freaked out and she was again super nice and was like don't worry about it at all. So for like a week we just kept texting and stuff and flirting and she was telling me all of the things she was into haha. She would like tell me all the things she wanted to do with me and it was hott haha. She was like I'm gonna take you shopping and then we're gonna get coffee and then I'm going to take you back to my place and I want to sit on your face lol. And yea we decided to meet up the next weekend. We went shopping, she bought me a cute top, we got boba (because I asked lol), and then we went back to her place and she...sat on me haha.

Okay that took a while sorry I just thought it was important for context. So this is where I need advice. When she says "sit on my face" she means it lol not like kneel over me while I go down on her, she meant she likes to sit on girl's faces like a pillow while she uh..does her thing lol. She was suuuper up front about this btw so it wasn't like a surprise or something just wanted to say that haha. She asked me about it and like I didn't know what to expect but I told her I would at least try it! Ngl I was pretty nervous but she was super excited because yea normally girls don't let her haha and she was really sweet so I wanted to try for her. Yea at first it didn't go well haha. She's not like big but she's taller than me and she works out a lot so...I don't want to call her heavy but...yea lol. Not like jacked, but tone...she takes care of herself yaknow? Anyways it's awesome lol EXCEPT it does make it more difficult haha. But we took it super slow and she made sure I could tap her and she would move right away so I could breath and stuff. At first I couldn't last for very long, like instant panic and like kinda painful, but after a few times I was actually able to hold it for a bit! It really wasn't that bad when I got used to it, but still I could only hold it for like 30 seconds at most.

So this is where I need help. For the first couple of times we met, whenever I would tap her she was like super quick to move and see if I was okay and tell me how amazing I was doing and stuff. And she would let me recover until I said I was ready before we tried again. And then like the second to last time it like started out the same but then after a few times she kinda...took a little longer to get off? Like to physically get off of me I mean lol. When it first happened I was like oh maybe I just felt like it took longer or like it was an accident so I was like whatever, but then last time we met up it happened again and like even went further. Okay so to be fair this last time she did ask if she could try to push it a little longer and I did say yes but even when I tapped her she was just like you can do it, take it a little more for me, you're doing so great and stuff and wait a lot longer to give me a break. Okay not like a lot longer but definitely a few seconds.

Okay so to be clear OVERALL I’m enjoying this haha. Like in no way is she like forcing this on me BUT I do have a question about what happened. Like in the moment I panicked a little bit honestly it wasn’t that bad and she was soooo happy after like it was kinda worth it, but I think a part of me feels like it wasn’t right for her to push me further even after I tapped her? Like I was really trying to hold it longer and I think I was really getting better but she did tell me she would love to be able to like do it for a minute at a time. I used to swim so like I should be able to hold my breath not sure why I panic sometimes haha but I am trying to get better. But like also at the same time I feel like maybe I agreed to let her push it further and I honestly think it helped me haha (in a weird way haha like getting used to dealing with the weight and the panic).

I guess I’m just not sure how to feel haha. I really do want to get better, I guess I’m just a little scared? Like she’s really sweet, I don’t think she would let anything happen to me but not having control is a little scary but also like REALLY exciting lol. Has anyone experienced something like this? Is it normal to have someone help you get better by pushing like this? Is there something I should say to her? I don’t want her to get self conscious or think I’m not interested, I love doing it for her and seeing how happy it makes her, so I’m scared to bring it up. What should I do? I’m supposed to meet her this weekend and I’m really excited but also this is the most nervous I’ve been.
