“I’ll show you the other room in case you want to try out any of the things in there,” said Suzy-Jayne as she stepped across the landing and ope...ed the other door. As I looked inside my eyes scanned the equipment contained within; various restraining devices including a spanking bench with wrist and ankle straps, a St Andrew’s Cross fixed to the chimney breast, a pillory, ceiling pulley and various rings bolted to the floor and walls. I’d seen similar at some of the clubs I’d been to and had. Then i had a courage to stand up and remove my pant.As i removed my pant my sister noticed my erection which is visible through the brief and said “this is the reason you are secretly admiring my body and my beauty. I thought you were gay but you got erection now by seeing me. Is it your idea to buy thong and panties for me?” I said “at first i am not gay i am bisexual”. “Yes, i told the sales women to give you sexy dress because i love your body and wanted to see you sexy and happy here”… She. Sometimes i'd find a bench or a railing and push backward against it, humping myself like an animal, pushing those rubber cocks deeper into me. Marco reached for my telephone and i jerked my hand back, snarling. He laughed and slapped me across the face. i turned and stumbled away, fingers poking desperately at the buttons on the phone. The vibrator turned on again and i leaned against the wall, felt a huge orgasm shaking my body, then the hum stopped and i screamed at him. "Bastard!" i threw. Daddy said it was important for her to get alone family time too. This meant Daddy and I had Sundays all to ourselves. “What are we going to do today Daddy?” I asked as I skipped into the living room. Daddy glanced up from the DVD player and looked at me, his eyes going to my little buds under my t-shirt. I wasn’t wearing one of the bralettes Mommy bought for me and my puffy nipples were sticking out. “Daddy’s going to introduce you to a new kind of sex baby girl,” he said calmly, turning on.
