From what I understand there are several in town it's just a matter of what your preferences are. Some are what can be defined as GFE while others may not DFK but will take a PSF for example. Heres a few that I can think up off the top of my head. Let me make sure I say as a disclaimer that I don't know what your idea of MATURE is, but I will guess your looking for more ESTABLISHED providers instead of newbies.

1. Sydney Burke, I have never had a session with her but she has numerous "GOOD" reviews.
2. Rachel Reid, I met her last night and she looks FUN. I will be calling her myself real soon.
3. League City Blake, alot of "GOOD" reviews on her to. I don't think she kisses very much, but I hear she allows a PSF.
4. Julia of Houston, I have never had session with her either but she is a Houston favorite.

Do your research on these ladies, I hope this helps.
