Mistress Sonja is a commercial Mistress which means that she demands payment for her “thing”.
Do not expect a dark SM-studio with candles, cages, crosses and girl slaves.
She runs a small studio, which is big enough for playing and is good equiped (she has a lot of small and big teasing toys/materials).
And besides, you will not be disappointed about her skills.
She is in for a soft as well as a hard play, mild or extreme,
for beginners or for submissive/slaves with (a lot of) experience, for 1-hoursessions but also longer.
As she likes the “personal touch” she will not forget the erotic aspect.
