Ok this time I tried EVEN WeChat.
When I search around, I always receive 3-4 messages from people nearby who say hello to me. I am used to ignore all of them (they include gays, TV and girls offering ST/BO).
This time I replied to one. We started some conversation. Her pic looked pretty and next-door type.
She claimed to live with family and be university student.
On my last day in Batam (ferry at 16:40), instead of doing the usual tour of joints for a last ST, I proposed her to meet for coffee, telling also that I needed to go to my room quickly to pack luggage. Unseen in Batam, she was at my table at Jco just 30 mins after the message. She rushed to shower and take her bike to ride to Nagoya Hill.
She was not so pretty as in pic, but the face was hers. I could not just see she is a bit chubby in reality. A nice girl indeed, not someone on the P4P scene.
Once sit at the cafe, she even refused the coffee due to lack of time, to come to my room immediately to help me for luggage. This request for help works always.
Needless to say, once in my room I had to shower and then...
She claimed to have NEVER tried a BJ, but, as she was on mens, she felt kinda obliged to learn on the job. She did her best to imitate what she has seen only in porn movies. For some reason, many Indonesian guys interpret sex as just penetration in vagina. All other holes seem not interesting for them.
Only at the door, leaving the room with me to checkout, she tried to ask me if I could give her a gift for her birthday next week....

OK, understood. I gave her 300, then rounded up to 400 to make her very very happy.
