Short Time or “ST” is the term used to define how long the girl will spend time with you. This is usually 1-2 hours and 1 shot. After 1 shot it is usually over and the girl will leave depending on the circumstance.
You will also hear of “short time” bars. These bars have facilities or rooms on premise where you can have sex with the girl.
Freelancers, Bar Girls, Go Go girls will also use this term to communicate how long they will expect to stay with you.
In Soapy Massage parlors, even after your 1 shot, you can still stay with the girl until the time is over depending on how long they give per session. For clarification speak with the Manager/Staff and they will tell you.
