As we got to the den, i asked Susan to sit down on the couch. Carol and I stood in front of her, and I said "Susan, I wonder how long you have been listening to us. I think it's been for quite a while hasn't it?" As she nodded, I continued "And you have been watching us fooling around before haven't you." Her eyes looked down as she nodded again - I knew I was right. I continued "Your sister has been having a slight problem and I have been helping her with it>' As Susan looked at us I said "Would you like to help me help out your sister with a problem?" Susan nodded again and I continued "Carol has mucho milk in her breasts and she needs some relief - Carol, show her what you mean>" Carol went over and sat next to Susan, took Susan's hand and placed it on her breast. As Susan touched her, I could see Carol start to sigh again, and I felt something in my shorts jump a bit.
