Mistress Natalia and her friend wanted to try fist fetish. Because it was their first time, they did not want to do it with someone else. They felt comfortable doing it to each other and so they prepared each other, had foreplay and used lots of lube to do it successfully. It was fun and they wondered whether dicks would feel the same after they had used fisting and had fun with it.
