Don't just go grabbing the girl's bits. You should ask first. You are allowed to ask what the boundaries are. So, she might say "hands off" but she might say "This isn't a museum, touch all you like"!
If the ad says MT (mutual touch) obviously get handsy. If not, you should probably follow Dharma's sage advice. Try gently touching a flank and saying,"Is this OK?"
One more note, most of the L1 girls prefer no digital penetration, so tread very softly there.
...and when you find a bodyrub girl that likes DATY and or mutual massage, please PM old Crossroads.
