I ended up living with my younger brother and his wife, but my younger brother's wife is very kind to me, my brother-in-law, and treats me like family, even more! The sense of distance is strange! I always wear clothes that emphasize my cleavage or extremely short skirts, and they trigger an erection in me without me even realizing it! What's more, when she saw that I had an erection, she would secretly cum on me... and she seemed to get really excited about having someone with whom I couldn't cum, so she was quite an innocent and lewd woman!
