My dad told me to just relax and he called him in. I knew Mikey really wasn’t my father, but my half-brother didn’t. We were both naked under the ...heets and we sat there when my brother entered. My dad told him to come sit down, so that we could talk, and he did. As the conversation moved on, my brother admitted to my dad that he and I had engaged in sex on a number of occasions. My dad looked at me and I nodded, telling him the entire truth. My brother seemed upset, since his father Shawn had. Well, not quite sterile. He has a very low sperm count. My mother just wasn't getting pregnant so being the swingers my parents and Sam's parents are, Sam's father took care of the job getting my mom pregnant with me."Now it was time for Steve to say, "Wow. You and Sam are half-sisters and second cousins."His nymphet looked at him very seriously. "It's a deep, dark family secret. You can't tell," she said to Steve.Steve hugged her tightly and told her that would be their secret."So that's why. "It really turns me on to hear you ask for it, Suzie. Tell me exactly what you want me to do and then I'll do it."Suzie gave another low giggle. She knew they were doing this for Buddy's benefit and it turned her on, knowing that Buddy would be hearing everything. "I want you to lick my hot pink pussy," Susie replied, squirming a little on the mattress. "Make me so hot I can't stand it. Then, after I cum that way, I'll tell you what else I want."Buddy felt his face turn red in the darkness.. She is very good at this, and she had me close to orgasm pretty quickly, so I I took her hand to slow her down, as I wanted the evening to last. As she slowed, but continued to stroke my cock, we watched the screen for a few more minutes as the lesbians continued to suck each other pussies, and finger each other. My wife commented that the girl being fingered should come already! About this time, I reached over between my wife’s legs, and began to lightly stroke her pussy hair, lightly running.
