For my international guests: Finally Calendaring is now possible for Sarah Blume as of August 2020 for real dates in Switzerland (Region Zurich) or Germany (Countrywide).
Please take account into the fact, that we do still live in the Corona Pandemic so not all BDSM possibilities you are used to will be possible.
Or … as we say in Germany: „Always keep a Bullwhip distance.“
Services out of the Area of Cologne, Germany (+/- 50km) can only be done as „Overnight“ in a Hotel near you. Pre-Charges (200 EUR minimum depending on your whishlist) do apply on every booking.
