So I'm fairly new to this world, have only done a couple of calls. I haven't really felt that the girls were that into it which was a little disappointing. Specifically I like C2C and JOI while I finish by cumming into my own mouth and on my face. I don't want to waste a girl's time before a call chatting too much to try to find out if she's really into it, or is just willing to watch, but I also feel like I want her having fun with it. How do I tell?
