My mother-in-law has always been beautiful, devoted and kind. One day, when I injured both arms and was in trouble because I couldn't take a bath, she said she would put on a swimsuit and wash my back... At first, I apologized and tried not to care, but it was a swimsuit when I was young. Or my mother-in-law is strangely sexy and there are many things sticking out of the swimsuit if you look closely. Involuntary erection. Of course it will be exposed, but the mother-in-law who washed my dick said: "Mom also has to wipe this place...". Moreover, saying "If it is with your mouth"... I am tearing my dick off!
