You sit and watch, your temperature rising, your dick so hard it hurts. I slowly swivel my hips as I pull the tank top over my head. My tummy is flat ...et soft and you gasp a quick intake of breath as I free my melons from the white lacey bra that was barely containing them. I close my eyes and run my hands up my belly, up under my breasts and cup them both hard one in each hand. I open my eyes and watch you watch me squeezing my nipples until they get hard and when I see the tight stretch. Despite all the pain and discomfort, I was so horny. My head swam. This was all so new and exciting.Lastly, Daddy bound my hands together across my stomach. I couldn't touch my pussy even if I had permission.“Beautiful,” he grinned.“Thank you, Daddy.”His eyes flashed over to Sun. “Get your slutty ass over here now, girl.”“Yes, Daddy,” she squeaked and hopped to her feet. She raced over, her small breasts jiggling. Her body was flushed, her pupils dilated, making her eyes seem even darker.. The 9 inch monster was stretching his boxers out, he tugged at the sides and pulled them down slowly to reveal his engorged member. Hannah gasped at the sight of it, then hurried looked away as her brother leaned in closer and began sliding his cock up and down her now wet slit. “Oh God, I’ve missed this, sis.” He moaned, “You were so tight when we were younger, I bet it’s even better now.”Hannah shut her eyes tight and let out a barely audible, “Oh God” as her brother began to stretch her. I pulled laid her down onto my couch as I ran into the other room coming back out with some rope and a knife. I tied her hands behind her back and laid the knife on a table near her. I then sat down and waited for her to come to so we could start the fun. Once she came to she realized her hands were bound behind her back so she began to scream I slapped her once across the face and said “Bitch shut the hell up you better not scream again if you know what’s good for you.” She silently nodded in.
