Living situation with sister was getting tense. Our joint p*** gooning m*********** was bugging her (understand I guess) because while she watched p*** I watched her. Was creepy for her. So she dared me to describe to her what I found hot while clothes were on for both of us. I accepted the dare and succeeded. She was breathing heavy and flushed when I was done. Dared me further to m********* for her as she slowly undressed and said it all again. I was on my knees moaning her name when I came. She let me clean up and catch my breath then laid across my lap and put my hands on her body and asked me to make her c** for me. She came sp violently and was sobbing as she came. I just cradled her and kept her feeling cherished. She napped in my lap. When she woke I did not ask I simply took her to the shower then held her in a bath. She never spoke. But when she was ready for bed she cuddled back against me and pulled my arms around her. She feltnme grow hard against her and asked me if I needed to come again. I told her I would rather wait until she was ready to herself again. She turned in my arms and rested her head on my chest and asked I would do it for her because she asked. She just lay alongside me touching my skin (but not down there) as she watched. I went slow as she looked down watching and when she could tell I was close she turned my face to look me in the eyed and reached down and cupped my balls with her hand pressing against the base of me and told me to c** for her. It was so intense to c** for her with us staring into each others’ eyes only a few inches apart. I was exhausted and she just kept a gentle grip on my balls as I dozed. I woke to feel her hand slowly slide up and down me and she asked me to please c** for her again. This time our eyes stayed glued to each others’. We slept like the dead.
