Sara said she heardthe whole thing and I should be on my best (i.e. most obedient) behaviorand do what I was told. I was to send her a picture when th...y were done.She then hung up. Before starting the polish Angie asked if I hadbrought my slip-ons. And I said they were in my bag. She went to getthem form the bag and out fell the diaper and pink plastic panties,right between me and Gail in the next chair. I turned beet red as Angieslowly put them back in the bag. I know Gail had to see them too.. Ryan went over to his bed and sat down to masturbate he didnt want her to see him. He had the image of his sister naked in the bath sponging her breasts in his mind as he masturbated faster and faster. His breathing increased as he orgasmed, his body spasming. Ryan clenched his teeth from crying out in pleasure. After Ryan got his breath back he felt ashamed, hated himself because he just masturbated over his younger sister who was getting sexier every day. He put some trousers on and casually. "Let's go," she laughed, "and two people here are wearing way too much clothing."In minutes there were three of us naked on the bed, cuddling and kissing, with Sandy in the middle. Sheri and I took turns kissing and feeding her, then kissing and feeding each other. If we spent too much time away from Sandy, she reminded us.It was better. Playful, casual. Lots of touching and fondling, kissing and licking. Nothing overtly sexual, except for a lot of breast play.I was achingly hard, and Sandy was. ’Finally I hung my head. ‘Okay, Daddy. I will.’‘Good. And since it took you so long to respond, I think you owe Daddy another small apology.’Grinning, I reached over and smoothed my hands up his jeans, rubbing the hard lump concealed in them.I didn’t do that for too long, though. Daddy hates to be teased for too long and I didn’t want him to be angry with me.Sliding the zip down, I reached carefully into his boxers and pulled out his rigid cock. He had such a beautiful cock.I licked my lips.
