Wearing G String to massage

As a man, I wore a G String to an Asian massage. They told me to take off all my clothes and lay down on the bed. I stripped down to my G string and laid down on the bed. She came in and said something but can't remember.

She started on the massage and then left the room for a minute but she left the door open. I heard other voices from behind and walking around.

She came back in and closed the door. She got to my butt and pulled the G String down to just below my butt. She massaged my butt and inner thighs, then pulled the G string back up and gave it a little tug.

Then she had me turn over to be face up. So, I am lying there with a small pouch and my dick gets hard. She massages my chest and legs while gently brushing up to my hard dick. She finished, handed me a towel and said I could finish. So I started stroking with her in the room as she cleaned up and then exploded on my chest. I cleaned up, got dressed and she walked me to the front.
