"My younger brother sucks on my breasts every day..." It all started about a month ago when something happened at work and my younger brother became depressed and missed work for a few days without permission... "I'm letting him suck on my breasts to help him get back into society... It doesn't feel good... It definitely doesn't feel good..." The older sister lets her younger brother suck on her breasts for his own sake, and the younger brother sucks on his breasts to motivate himself, crossing the line into the brother and sister's breast addiction...
