When I came back out, she asked me what was up and why I didn't want to cum myself. So I decided I had to tell her I had cum with her mom and see how she reacted. I wanted to play it off as a much smaller thing than what really went on just to gauge her response. I was shocked by how she reacted. I sat. I said ok and went back to my room to play Nintendo. About any hour later I heard Lucy call out to me Mike can you come here for a second She was holding my sister in her arms Can you get the baby powder from the bathroom and the wipes.

He kissed my neck and over the top of my breasts as he slowly unbuttoned my shirt. I let it whisper down to the floor while he kissed my shoulders, hands… He knelt in front of me and kissed my stomach while he unfastened my pants and slid them to the floor, helping me out of them. He kissed my hips and the keyhole cutout of my thong, slipping a hand between my legs and brushing my clit with his thumb. Instantly rigid – I got a little self-conscious and gently pulled him to his feet. I helped.
