Body Therapy in Tamuning. I don't see this place mentioned often but I've been there a few times. Usually just Mama there but sometimes there might be a girl or two also. Mama also has a couple girls on her phone that she can call so just ask her. The last two girls I was with were both mid to late 30's looking, decent bodies and great performers.
I forgot to ask her if she has any kind of local girls ie, Chamorro, Micronesian, Caucasian, Filipino, etc. (not Chinese) but I will on the next trip.
