I'd say my pain tolerance, not threshold. It pushes the boundary for sure. Well, the first time I saw her, Cecilia was off. Then I snuck in another day when they were both working and booked Cherry for 90 minutes to really get a feel of her massage skills, since first time was 30 mins before close. However, yesterday I chose Cherry again for 2 hours, really needed a good workover. I mentioned in a few posts back the difference between the 2. If you want a more fun, sexy time choose Cecilia, but if you want a good massage choose Cherry.
