My sister-in-law, introduced to me by my newlywed brother, turns out to be a former sex worker! And she was my favorite girl! It seems my brother knows nothing about his wife's past, and fearing that I might spill the beans, she offered to keep quiet by taking my penis in her mouth! And since she's no longer in the sex industry, there are no prohibited acts! Everything is allowed, including full sex and creampies, all for free, in a free-for-all state!
