"Hmmm, I feel panties. Nina, are you wearing panties?" Yes Master," Nina responded, "I always wear panties. Do you want me to take them off too? Shoul...d I take them off here?" she added hopefully." Yes I want you to take them off," he informed Nina, "no I don't want you to do it here. Now scoot," he added, swatting her playfully on the ass, as she dashed for the bathroom.When Nina returned a moment later, she faced Steve, looked him in the eye, and said, "I'm naked under this dress now. K blushed and looked down. It hit me then that kiss in the car had marked K as mine. I knew it was incest to want my older sister but what boy does not want to fuck his older pretty sister. Older sisters are made for sex to my way of thinking. After all those years of being cock teased; my simply taking her mouth to mine had marked her and she knew it. I have read that 18% of College girls had fucked a brother and sibling incest is the most common.Later I went to Karen's room and I respectfully. We lie like that for a long time, feeling our love wash between us. I gaze at her face, and she turns her head and returns the look. We smile at each other."I never knew anyone could feel like this, Mary," she whispers."I'm so glad. I've been with girls and women before, but I've never felt the way I do with you." I love you, Mary." I love you too, Lydia. So much." I want to please you now." I won't complain," I reply, grinning at her.I lie back and Lydia lies on top of me, kissing me. I kiss. I looked at her and she knew what was about to happen. She nodded, held tight to me and, without breaking eye contact, I came deep in her. I used long and slow thrusts to fill her and kissed her as the last of my load emptied out of me. “Oh Steve,” she whispered when I stopped, spent of cum. “This can’t end, it really can’t. I love Phil but I want you. Please tell me this isn’t the end.” I held her tight and kissed her before answering,“It has to end. Jay and I have an agreement and I would.
