I want to ask about if i have 20 minutes with the girl and i cum before the time is up, some people told me you can not continue. Therefore, i want to know if this is true or not

Yes, usually in a standard €50 session, once you cum....that's it, finish!

Thank you bro, but what about the 1 hour session ?

Depends on the girl. If you fork over €200 to a rip-off girl, she'll probably kick you out as soon as you cum once regardless of how much time is left (if you can even cum at all with the level of service you're likely to get in that scenario). With any decent girl, in a longer session, multiple pops are on the table.

I do hourlong sessions with Simona, Desi, and Veronika regularly, and we always go more than once.

Just mention it at the door as part of your requirements.

Thank you guys so much
