Erotic massage parlours in Leuven are always on the move or “temporarily unavailable”. They’re the usual suspects when it comes to human traffic and pimping charges. Police hit them hard and often, making sure employees have proper visas. Your best bet for a rub and tug in Leuven - or Louvain as the name in French goes - are the girls who advertise on nationwide directories such as Redlights ((https://www.redlights.be/) and Afspraakjes (http://www.afspraakjes.com/).
Very rarely you will come across independent erotic masseuses who run their own website. Have a look at the professional personal website and the impressive photo gallery of Sensual Kelly (https://www.sensualkellyleuvenmassageart.com/. According to the info on the website this sensual ebony lady offers GFE service as well. Prices for erotic massage in Leuven vary but rarely go lower than €100 for an hour. When you want more massage services and masseuses to pick from you are far better off taking the train to Brussels where the offer is obviously more diverse and larger.
