Tips based on past experiences...
Be a Gentle-Manyak but don't be naive.
Never pay in advance, kahit partial lang ng fee.
Once the fee is agreed, don't go haggling when your handing her the fee.
You're paying for the service, not the person. Respect.
Yes, you're paying her to get-off, but as a GM, it's always good to make her cum.
If you cut fast, then you better know how to eat pussy well.
Haggle but don't push it, if she says no, then itxs a NO.
Hygiene. Fresh breath, fresh balls. And require the same hygiene from the PSP.
