Is it wrong for me to have sexual feelings for my sister-n-law? My girl is my world; she gives me everything. But, this has been eating at me. Her sister and I had a strange encounter which I don't think she remembers. I played with her for two hours and I thought she was awake because she would move and turn towards me. If she wanted me to stop, she would tell me or let me know, right? Should I let it go, or try again?
