My sister-in-law is a quiet woman whose hobby is reading. She is always rational and I have never seen her get upset. Could it be that she has feelings for me, her younger brother? One night, when the mood was just right, my sister-in-law pressed her body against me and seduced me with dirty talk! I hesitated but accepted, and she pistoned me while whispering dirty words in my ear! And she kept cumming inside me without pulling out! Her dirty talk made my brain melt, and I ejaculated like I had never felt before! This pleasure is seriously crazy! I'm addicted!
