She stood still for a few seconds, then looked over her shoulder, smiled and shut the door.Beth and I looked at each other with our mouth open.“Did ...ou see that Steven? Mom showed us her ass on purpose.”“How could I miss it? Do you think Mom is teasing us so we will try something with her?”“I don’t know Steven, I’m confused. Sometimes I think so and then it scares me when I think I might really try doing something with her. She is our mother for Christ’s sake.”As soon as we saw mom drive out of. So Dave falls asleep and Lisa and Tommy still wanted to party and I was getting tired. Lisa said I think I'll go to the room and change out of my dress, Tommy said I'll get more ice and have drinks ready when yall get back. Kim you go with lisa to the room. Ok I said I'll take a walk with her. About 20 minutes later Tommy comes into the room with our drinks and said what's taking so long? yall having sex! What? No!, We ran into some friends of kim and daves and we talked for 10 minutes we just. Now why don’t you tighten up that little thing just a wee bit more and bounce just a wee bit higher and let’s get my rocks off before they get here?”“Oops, Daddy. I hear the doorbell. I guess all three of you are cumming or coming simultaneously, huh?” She sweetly mentioned.“Hi, Dad. Come on in. do you know why you are here?”“Not really, son, but I knew it was very important to get here and help Luci with something you couldn’t handle, so I came as quickly as I could.”“So did I, Dad. So did I”,. . he says hopefully. I nod my assent, and he steps over to the bed, kneeling and tying one of the ribbons around my wrist, showing me how I can pull it to get free, and taking the other end and securing it to the bed post. Already I feel that I am going to enjoy it, the feel of the ribbon sending shivers through me. He moves to the other side of the bed, securing my other wrist and asking if it is too tight, if I am comfortable, and I assure him that I am. He whispers the safe word to me so.
