GF's First Face Sitting Goes Wrong

Ok, I'm finally ready for this. I know how much face sitting turns you on, and you've been dropping hints all week about how bad you want this. I've decided I'm finally ready to sit on your face, but I've never done this before. My butt is really big, and I'm worried it could smother you completely. Are you sure it's safe if I just sit on your face? I'm really nervous, but also really turned on. If you think this is safe, we can try it. Tell me how you want to me sit on you, and let me see you jerk off once I do. I want to watch you cumming as I sit on your face and ride it. You're sure squirming a lot down there. I can't tell if it's because you're about to cum really fucking hard or....honey? Hey? Are you....? Oh no... Oh no, uh oh, no, no, no. This is not good. Did you just... or are you...honey? Please say something? Dear? I had too much fun riding your face!
