unfortunately for you, some of them make a lot of money by just sitting there and showing their feet. the target audience is the mzungu who has very strange fetishes, especially for African women.
there are at least three Kenyan couples.
Atomic something... - though she comes alone nowadays
Pricila and Rob
Yummy something.....
but you are right, it's still not a viable way of making money for Kenyan girls (over 70% left after Lockdown was lifted), so maybe next year if Corona persists, there will be more enjoyable and vibrant girls and couples.
