The outcall service is more expensive than the in-house massage. The outcall massage sex average cost is around 5000 baht. However, this price is quite cheaper if you compare it to the prices in Hong Kong. With this price, you can get a girl to give you massage sex in the hotel you stay in. You can also look for girls online, for instance, on Thai cupid. You can take her out and ask her to give you a happy ending massage. For a good girl, you might require some time for this.
