“C’mon Steph. I’ll show you our family room.The family room sat a half-floor lower than the living room and a half-floor above Dad’s office. O... their way, Stephanie commented how the reversed floorplan made everything look odd.“What do you want to play?” he asked. They stood at Jason’s shelf of game chips.Peering at the labels, she said, “I don’t know any of these. Pick something fun.”Jason handed Stephanie a controller then pushed the ottoman against the couch. He plopped down, kicked his. “You are doing fine, bro!” Her eyes were back on my erect cock. Her hands went straight for my cock. “You’re fucking hard!!!” “Would you like to titty-fuck me? I’ll let you if you want!” she said with a wicked smile on her face. For me the answer was obvious. “Sure sis! Tell me what to do.” Sis knelt before me and took my dick in her boobs. Shereen spit on my dick to lubricate it as I rubbed it in between her tits. The physical contact was arousing us siblings. “Well? Do you like it? You can. ”John suggested they go out of a meal to save cooking on her first evening, and she readily agreed.When they returned, she left him and went to sort out her room and unpack, then she sat in ‘her’ room for a while, soaking in the feeling that she was at home there. At nine, her mobile rang. It was Peter.“Where are you?” he asked without preamble.“At John’s,” she said coldly.“Didn’t he find you a hotel?”“Peter, you know that was never the plan. I wouldn’t have gone to a hotel if he’d booked one.. You want me to set you up with one?" Sure, just as soon as you talk your father into it." They both laughed. From there the conversation went onto other things.In bed that night I asked my wife, "Does she know we were listening?" Yes, but she doesn't know how long." Are you jealous of her?" I guess I'm jealous of her youth and her freedom."I said, "I was thinking how I would feel if I came home and heard that noise from our bedroom -- knowing your were with someone like him."That got my wife's.
